What can be done with a corner grinder

Corner grinder is an electric tool, without which it is difficult to imagine the work of a locksmith or repairman. The angular grinder is used for cutting the material and grinding of finished parts. The angle grinding machine refers to instruments of increased danger, before starting work it is necessary to familiarize yourself with safety precautions and the rules of use. But in addition to theoretical knowledge, it is important to know how to properly use a corner grinder, depending on the material with which you have to work.

It is forbidden to start working with a corner grinder if the operator feels malaise, tired or not sleeping. The main task is to ensure the safe use of a corner grinder, for this you will need personal protection and a casing from the tool. Overalls during the saw. An obligatory part of the work. Protect your eyes and face with a mask, headphones or beryushi will save from high noise. Do not forget about clothes with long sleeves and gloves of dense leather, which will protect from sparks and flying pieces of material. The corner grinder cover is a special protective part of the tool located directly between the operator’s hands and the processed material. Experts do not recommend neglecting the casing and dismantling it from the tool, it protects against sparks in the direction of the operator, and will also protect it from injuries in the event of a breakdown of the abrasive disk. There are also requirements for the choice of disk. Do not exceed the radius of the disk specified in the technical passport of the corner grinder. Select a disc of this size so that the thickness of the processed part does not exceed half of the radius of the disk.

The main rule of working with corner grinding is to use specialized discs for each of the materials. Neglect of this rule will lead to the destruction of the cutting disk, the rapid failure of the tool, as well as to injury to the operator. Consider the features of work with various materials.

  • Cutting angular grinder of concrete. For work you will need a diamond disk. The peculiarity of concrete work is systematic cooling with water. Use the spray gun, spray the surface of the material, as well as the disk itself to avoid overheating (first make sure that there is no electric current source next to the disk).
  • Cutting corner grinding tiles. Optimal to cut tiles use a tile cutter. But if this is not possible, an angular grinder with a grinding disk with diamond spray is also suitable. With prolonged work, select discs for wet cutting to make several sections a disk for dry cutting is suitable. Carefully secure the tiles with the grip before the cut.

Rolling the parts with specially selected circles of large thickness. The choice of a circle, as well as during cutting, depends on the material with which work is underway.

  • Grinding corner grinder of wood. Depending on the condition of the tree, use the peeling (removal of varnish and paint), grinding and polishing (rough grinding) and sandpaper (thin grinding, completion of the process) of the nozzle.
  • Grinding corner grinder of concrete. For directly concrete, use the dry grinding method. The flooring in the form of marble crumbs or mosaics is customary to complete using the method of wet grinding.
  • Grinding corner grinder of metal. Working with metal takes place in two stages: the removal of burrs with an abrasive circle and polishing a petal nozzle.

The assortment of disks for corner grinder is wide, but their skillful use and combination will lead to a quick and qualitative result.

What can be done with a corner grinder?

Initially, this power tool was produced only as a grinding machine, but over time it was improved, which made it possible to use it in various types of work.

  • Process different types of building foundations (brick, concrete, etc.D.);
  • Polish the surface;
  • Cut the material, including stone and metal;
  • Clean a different surface;

With the correct selection of additional devices, all these tasks can be performed only by this power tool.

What is the difference between a professional corner grinder and household?

Corner grinder used in large.Scale construction work have significant differences from household models. Therefore, their cost will differ.

Therefore, before going to the store for a power tool of this type, think carefully for what purposes it may be necessary for you.

The main features of a professional angular grinding machine are:

  • In high wear resistance of nodes, which allows you to use it in prolonged work;
  • In power characteristics (more than 1,500 watts);
  • In significant weight, the cause of which are special nodes and a high.Strength case;
  • In the low probability of overheating;
  • In additional functions that can facilitate prolonged work on it;
  • In the cost of the machine and in components to it;

The manufacturer indicates the characteristics of the corner grinder in the description, but also in the instructions for use.

How to work properly a corner grinder: step.By.Step instructions

Knowledge of how to work properly a corner grinder can help achieve the goal and protect life, as well as health. The aforementioned tool does not tolerate safety precautions. Manufacturers emphasize that equipment operation should be accompanied by compliance with the instructions.

make, corner, grinding, opportunity, which, direction

The angle grinding machine today is much more functional than a few years ago, when the tool could be useful only for grinding work. Today, these devices are indispensable in metalworking and construction. Outwardly, the angular grinder looks unpretentious, it has a cylindrical case, on the one side of which there is a handle, and on the other. A mount for nozzles. It is the nozzles that make this unit multifunctional. They are fixed on a spindle, while the discs are additionally attached with a clamping nut and a flange. This measure is mandatory when working with the described tool.

What is the angular grinder for

Having examined modern angle grinders, you will note that they are able to cope with many tasks, including:

For each type of work and material, a certain abrasive tool should be used.

General recommendations for working with an angular grinder

In order to understand how to properly work with a corner grinder, you must familiarize yourself with the assortment of nozzles, among which are brushes and circles. The former are intended for polishing and cleaning surfaces. In this case, you can polish welding seams and clean the metal from rust. Different circles can be used to perform different tasks depending on the composition. You can cut ceramics alone, while others are suitable for metal. You can familiarize yourself with this information by considering the instruction on the disk or packaging.

Which corner grinder to choose

If you have a question about how to work properly a corner grinder, then you should know that there are different no only nozzles, but also angling machines. They are represented in different classes, among which:

The last option is suitable for operation for a limited time every day. Professional angle grinding machine is capable of working every day for several hours. As for industrial equipment, it is a device that works almost tirelessly. Tools differ in appearance. Thus, the case can be supplemented with one or two handles, as well as vibration.Absorbing handles.

Safety precautions during the operation of a corner grinder

Before starting the work process, you must prepare the tool. For this, a circle is selected and installed. The motor has a certain power, it provides for the need to choose a circle of certain sizes. The smaller the circle, the greater the speed of rotation it is able to maintain. If you use the circle incorrectly, this will cause wear of equipment and deformation of nozzles.

If you are thinking about how to work properly a corner grinder to avoid injuries, you should know that discs should not be installed on the tool, the dimensions of which are more than those for which the unit is intended. Nozzles should not be deformed. If cracks or potholes appeared on the circle, then you should get rid of them. Do not use those circles that have deviations from the original form.

Rules and recommendations

After fastening the circle, the tool should be launched and checked in idle mode. Within 30 seconds, the equipment is driven away at maximum speeds. If you have not noticed extraneous sounds and vibrations, and the protective casing does not hurt the disk, then you can start work.

Quite often, novice home masters ask about how to work properly a corner grinder. Before starting manipulations, the operator himself should prepare, for this you need to wear:

The operator needs to remove all the jewelry, for example, hours and bracelets, because they can be wound on a circle. You can not start work if you feel fatigue or are intoxicated. The use of saw disks for wood when working with an angle grinding machine is excluded.

Fire safety and mounting parts

The operator needs to make sure that there is no one in the cutting plane. Until the discharge of the disk is completely stopped, you can not release the tool from the hands. You should not touch the equipment earlier than it cools down. In the working area there should not be flammable objects, namely:

If you are interested in the question of how to properly work with a corner grinder, then you should think about a reliable attachment of parts. Everything that is processed and cut should be recorded. The exception is the elements that will remain motionless under the influence of their own weight, the slabs and stones should include this. The part can be recorded in a vice. In the absence of such an opportunity, you should use the help of a partner, which will fix the workpiece or pipe with the divorce key. It is forbidden to hold the processed parts in the hands.

How to cut a corner grinder

Many owners of the described equipment in the first stages of its operation are interested in the question of how to work correctly with a small corner grinder. It is worth noting that the methodology of cutting the workpiece in this case is no different from the time when the professional class tool is used in the work. Workplaces must be cleaned, the workpiece must be placed, only after you can start work.

Equipment must be held with two hands. If the circle is jammed, the tool should not be torn out of the hands. You should always be prepared for the opposite impact, which can cause a strong displacement. In general, a reverse blow is one of the most dangerous points in the operation of an angle grinding machine. In this case, there is a sharp sudden discharge of the tool when jaming the disk in the workpiece.

How to work with a corner grinder correctly and safely

Corner grinder is the most popular tool, both in everyday life and in production: they cut, polish and clean the surfaces from rust. At the same time, you need to understand how to work with a corner grinder correctly, because it is a fairly traumatic tool that can cause serious injuries.

Therefore, before picking up a corner grinder, carefully study the technique of working with this tool. Be sure to learn how to work with a corner grinder, what can be done and what you can’t do. In this article of the construction magazine Samastroyka.Ru will talk about how to properly use a corner grinder, and what errors should not be allowed.

What is a corner grinder

Corner grinder is the name of the angular grinding machine (corner grinding), a colloquial one, which appeared among the people because of its country of production, Bulgaria. It was Bulgaria who became the birthplace of such a popular tool that many of us are used to using almost daily. Having a fairly simple design, at the same time, the angular grinder is very convenient, if not, a multifunctional tool. By the way, many craftsmen found him another application, since various ideas Corner grinder, do not stop appearing in the vast World Wide Web.

Modern corner grinder can do a lot:

  • Grinding and polishing;
  • Cutting materials, not only of metal, but also from stone, glass, concrete, as well as wood. By the way, when working with a corner grinding of wood, it is worth observing particular caution, because, in principle, this tool is not intended for working with wood.

Over time, the corner grinder has become a simply indispensable tool in work. For car deles, welders, as well as builders of all stripes.

Safety precautions or how to work with a corner grinder

What you need to know first of all to work with a corner grinder:

  • The tool is unacceptable without a protective casing;
  • When using a corner grinder, you should always put on glasses to protect against the ward of metal, which can easily fly into the eye;
  • Sparks from the corner grinder should fly back, although many reduce the corner grinder, so that the sparks fly forward, and not under the feet. However, in this case, holding the tool in your hands becomes much more problematic;
  • During operation on the corner grinder, water should not pour. Some craftsmen, for example, pour water onto the disk of corner grinders when cutting concrete to reduce the amount of dust, but this can lead to electric shock;
  • Be sure, before cutting the metal of the corner grinder, you need to think about where the sparks will fly and whether something is caught up as a result.

In addition, a more diameter disk should not be placed on an angular grinder than you can. Some clever men, in the absence of a disk, remove protection and put a larger diameter disk, which is not intended for the manufacturer of the tool. As a result, not only the level of vibration increases, but also the risks associated with damage to the circle, which inevitably leads to serious injuries in the absence of a protective casing.

Also, you can not use when working with a corner grinder, circles that have some obvious defects. Very often the disk “walks” from side to side, which indicates a violation of its internal reinforcement. All this can lead to the destruction of the disk at the time of cutting materials.

What cannot be done when working with a corner grinding?

Before working with a corner grinder, you must make sure that the processed part is securely fixed in the vice. Very often, pressing the corner or sheet of metal to the ground, and carrying out its cutting, the disk of corner grinder applies to stones and other objects, which in the literal sense of the word are scattered to the sides at high speed. Therefore, it is necessary to provide a short distance from the ground, put something under the processed material.

The worst thing when working with a corner grinder is a reverse blow when the disk is closed or the tool is held not tight enough in the hands. Keep the corner grinder is allowed only with two hands and very tight. At the same time, the body position should be located so that the corner grinder is located between the legs of a working person, and the body is not on the same line with a cut.

In this case, even if the corner grinder will vomit from the hands, the disk will go aside and will not cause much harm.

Memo for those who work with a corner grinder

Be sure, before working with a corner grinder, remember:

  • It is necessary to cut the material only when the disk of corner grinding rotates at maximum speed. It is forbidden to turn on the tool at the moment when the disk is in the puncture.
  • Do not make excessive effort to an angular grinder during metal cutting or any other material. Firstly, you are there to the risk of burning a corner grinder, and secondly, the risk of jamming the circle in the material increases, and, therefore, its damage.
  • It is best to start cutting a corner grinder from a place where there is a smallest cross section. This is especially true for cutting corner grinding metal profiles.
  • Carrying out a stroke with a corner grinder, you always need to wear a respirator and glasses.
  • While working with a corner grinder, you need to understand risks, so attention should be maximum, 100%.

In addition to all of the above, you can also add that many people like to cut corner grinder, trees. This is a very dangerous activity that can lead to severe injuries, and even death.

Main secrets of work with an angular grinder: we master a useful power tool

Corner grinding machine (angular grinder) has a fairly wide area of ​​application. Welding, installation of various kinds of reinforcement frames, including pouring a tape or slab foundation, can not do without it. Even the arrangement of the grounding circuit in the courtyard of a private house involves the use of such a power tool. However, it is worth remembering the safety rules when working with it. Today we will consider 5 main secrets of working with corner grinding, which will help protect your home master from possible injuries.

Working with corner grinder requires accuracy and marginal care

What is an angular grinder intended for and what is intended: General information

The name itself says that it is designed to grind the corners. However, the work performed by the corner grinder will depend on the selected and installed disk. For example, it can be a detachment, a grinder or a special metal brush that allows you to quickly rip off the rust from the metal surface. But brushes are used extremely rare. The most common use of an angular grinding machine can be called a cutting of various metal. Pipes, sheets, corners or channels.

Keep the corner grinder when working should be very tight in one position, without heating on the side

It is cutting that is considered the most dangerous work using corner grinder. In order for this work to be performed faster, easier and safer, you should choose the right type of tool.

What corner grinder can be found on Russian shelves

The corner grinder differs from each other not only in size and weight, but also the speed of rotation of the disk. Heavier angular grinders of medium sizes accelerate the disk to 6000-7000 rpm. For this kind of device, the speed is small, but at the same time the power allows you to “dissolve” a rather thick.Walled metal.

Good to know! The smaller the number of revolutions per minute, the greater the diameter of the disk can be used to work.

For household needs, corner grinding machines are often used, which have a very small weight that allows you to hold it with one hand, and reduced dimensions. Such corner grinder develops up to 16,000 rpm., And the discs used for work are very small.

There are very large corner grinders that can only work with a special stand, but they are used only for industrial needs and, in general, they can already be attributed to the category of a end saw. Such equipment will not be considered today.

The corner grinder of medium.Sized power is higher, but the number of disk revolutions per minute

Secrets of safe work with corner grind

In order to reduce injury hazard, various protection elements are used: working costumes made of dense fabric, a millet.Glass mask, gloves. However, confidence in security during work can only be fulfilled by the implementation of the basic rules, which will now be considered.

Rule: The location of the adjustable handle

The handle should be located on top. Many masters screw it on the side, in a horizontal position, arguing that the area of ​​the cut is better visible in this way, and therefore higher security, but this is a dangerous error. Only with a vertical arrangement of the handle on top it is possible to provide a strong grip and protect yourself and others from the option when, when you “eat” the disk, the corner grinder flies out of hand.

The handle should be located on top. This will provide a reliable grip

Many will ask why, in this case, the side location of the handle is provided. It is used in the production of grinding work, when there is no danger of “biting” the disk with metal details.

Rule: Direct direction direction

Inexperienced masters often believe that the disk should rotate, making the cut “from themselves” so that the sparks fly away from the operator. However, no specialist who has experience working with angular grinding machines will not agree with this statement. The fact is that a special casing protects from flying sparks, so they are not terrible to the master. Here the question arises in another: how the corner grinder will behave in the case of “biting” the disk with a metal?

When rotating “on itself”, a sharply stopped chopped disk leads to the fact that the corner grinder breaks out of the operator’s hands in the direction of the ground, t.E. Away from the master. If this happens during the reverse rotation, “from myself”, the corner grinder can fly into the head of her work, which at best will be very unpleasant, and in the worst it is not only fraught with a hospital bed, but also more terrible consequences.

The disk should rotate “on itself”. The protective casing will not give a spark to fly in the eyes, and the use will be safer

Rule: The location of the metal during its cutting

Many novice masters make a serious mistake, fixing the sawing pipe or channel on both sides and starting cutting between fasteners. With this arrangement, the probability of jamming the disk at the end of the saw. For example, you can recall an ordinary board, which everyone sawed at least once in his life. At the end, the hacksaw clamps and has to look for a position that will lead to the opposite effect. The same story with pipes. One end should be on weight. In this case, the fraud will occur, not jamming.

What you need to know about corner grinder

What you need to know about corner grinding 10.09.2012 What you need to know about the corner grinding of Posteed on 10.09.2012 in instrument plumbing, plumbing

Corner grinding machine or, as we often used to call it, the corner grinder came to us, oddly enough, from Bulgaria in the 1970s.

In general, corner grinder (or grinding machines) is a rather extensive concept. But I will talk about the features of working with a corner grinder from the point of view of plumbing. I will share examples from my experience. And I will say a few words about safety measures when working with a tool.

Conventionally for myself, I divided the corner grinder into three types: small, medium and large. (Do not take it very large)

The best combination, in my opinion, is to have a large and small corner grinder in work.

It is very convenient to crawl into narrow places with a small corner grinder, it is easier and safer (it is easier to hold it) of a medium.Sized angular grinder. This is the same alternative when there is no large one, and the little one is no longer sinking. Well, and large is designed for cutting large pipes (it has a large cut depth). T.E. It has a larger diameter disk and, accordingly, it turns out to be a cutter, which is important when working with large diameters.

Once or twice for household needs or every day (professional need)? If you need a corner grinder for one.Time work or you buy it just in case, then buy a household. She is inexpensive, and if you have to work all day, just let her cool every half an hour.

If for household needs I want a corner grinder more safer (so as not to overheat), I recommend taking a small corner grinder at the price of 3-4 cheap. Large cutting machines for household purposes are very rare. If you work with pipes, then a small corner grinder can be cut pipes up to a diameter of 50 mm (with a disk of 125 mm) when buying inexpensive Bulgarians, you must keep in mind that it cannot serve for a long time, because it is made of cheaper materials.

The first thing that usually “flies” in household Bulgarians during intensive operation is the gearboxes of the gearbox.

10 points that you need to pay attention to when buying a corner grinder for constant work

The speed of the disk is on average 6. 11 thousand. Rpm. Some are spinning faster. When buying a corner grinder, it would be useful to understand whether you will need to adjust the speed of rotation of the disk. For example, if you need to polish something melting or even flammable at high speeds, as I often have to do, then the speed adjustment will be very useful.

Power = Endurance.

The more powerful the corner grinder, the more hard it will be. Professional corner grinder, as a rule, is an order of magnitude more powerful than household, due to which the tool is easier to work and it takes much more time to overheat.

The system of smooth start.

Many powerful grinder of a more expensive segment are equipped with an electronic system that smoothly launches a disk. T.E. The disk is turned on not instantly, but with current limitation and, with speed growth, the current increases by the maximum. Although this happens quickly and to determine whether there is such a system in a corner grinder, you need to turn it on. If when turning on, the corner grinder does not jump out of the hands, the system works. However, you should not confuse the smooth starting system with a weak corner grinder. There are corner grinders in themselves low.Power. They are launched with a small jerk and spin a few seconds. But it is worth touching such a corner grinder to the working material, as the turns significantly fall.

Maintaining the speed of rotation.

Some corner grinders are equipped with a system that allows maintaining the optimal speed of disk rotation. T.E. When cutting the material, the speed of rotation of the disk will not depend on the load on which force you will press on the corner grinder. (Naturally, we are talking about pressing within reasonable limits, because it can be unsafe)

Turning off the brushes when the power is turned off.

Many professional grinder are equipped with a system of turning off the brushes with a sudden disconnection of electricity. For example, if the power was disconnected in time, from when it turned on, the corner grinder will not begin to work. It must be turned off and turned on again. It happens that during operation, the power breaks off, and the master forgetting to turn off the corner grinder, goes to look for a rupture of the chain or the reason for the disconnection. If the electricity unexpectedly turned on, from at the time of the absence of the master the corner grinder with such a system does not turn on and will not begin to saw everything around him.

Protection against random inclusion.

Most of the Bulgarians are equipped with a safe switch button. To start such a tool, you need to push the lever forward and only then press the button.

Stop by rupture and clip of disk.

Some grinding machines have a system that recognizes the disk rupture and turns off. And such a corner grinder will turn off if the disk starts to clamp. The machine will not have to pull out and the risk that the disk will fly to minimum.

Balancing disk.

Expensive grinders can automatically balance the disk. When cutting, very often the disk wear out unevenly. To prevent strong vibrations during operation, the spindle has a cunning bearing that balances an uneven disc.

Options for fastening pens.

Cars come with a fixed main handle and with an additional handle, which can be twisted. And there are grinder where this very handle can be screwed on the other side or from above.

Vibration protection.

In expensive versions, pens are made from vibration protection material for more comfortable work. This is important when working with a machine. In addition to all this, professional corner grinders are performed in a solid and moisture.Proof case, which is important in plumbing.

make, corner, grinding, opportunity, which, direction

Safety precautions

Never neglect safety precautions when working with grinder. In the end I will tell a real case from my practice. But in order.

Service angular grinding

A little about how to serve a corner grinder.

The change in the changes in the working nozzles, periodic adding and changing the oil in the gearbox, cleaning the motor compartment and the engine from dust, and the timely change of contact brushes can be attributed to the care of the corner grinder.

The change of nozzles is quite simple:

  • Turn off the angular grinder from the outlet to exclude random inclusion;
  • We block the gearbox with the button on its back;
  • We unscrew the clamping nut with a special key;
  • Remove the worked disk or the old nozzle, put a new one and press it with a nut.

You can change the disk without a special key, for this, turning off the corner grinder from the network and blocking the gearbox with a button with one hand, the second turn the disk counterclockwise. If the force is sufficient, the clamping nut will unscrew with the disk.

To change the oil (lubricant), it is enough to remove the gearbox cover, twisting four, less often than six bolts.

Partially cleanse the corner grinder from dust that was stuffed into the housing, you can blow it with a stream of compressed air and processing it with a vacuum cleaner, but it is better to at least occasionally disassemble the entire body for cleaning.

What else can a coffee grinder will be prayed?

Last update May 10, 2020. Author: Know Your Grinder

Perhaps you will not quite be surprised that there are many other things that can be chopped with a coffee grinder, except for coffee.

There are several things that arise again and again, and people all the time ask about them.

So, we have compiled a list of frequently asked questions (FAQ) about whether the coffee grinder can grind ”, as well as some specific recommendations for certain types of coffee grinders that can be useful for each substance that you want to grind.

Let’s start with an explanation whether the coffee grinder can grind spices.

Can a coffee grinder grind spices?

One of the most frequently asked questions: is it possible to use a coffee grinder as a mill for spices?

As a rule, the answer to this question. Depends on the circumstances. No matter how disappointing this answer is, it is true.

Okay, then what it depends on? Since “spices”. This is a very wide term, and some spices are more difficult to grind than others, it depends on both the coffee grinder and the spice that you are going to grind.

In most cases, people are wondering whether a hard spice is too hard for grinding, but you should also think about whether the soft spice that can have its own problems. For example, create more mess and sniff the car if you do not apply it. Do not clean.

Yes, and if there is moisture in spices. Don’t even think! Moisture will lead to corrosion of the coffee grinder (for more details see. In the next section about kitchen combines).

We think the best option. This is to buy a coffee grinder that advertises itself as a grinder for spices, and there are many of them. In fact, many coffee grinders advertise and design their coffee grinders specifically for grinding spices, as well as coffee.

Grinding of burrs vs. Lying “Grinding”

Most often, spices grinders are shredions with blades specially designed for “grinding” spices.

Arc Welding 2DVD

When it comes to grinding machines, technically speaking, they actually cut your spices into slices, and not “grind” them, which is more like a grout.

This also applies to coffee. However, some will say that this is one and the same. When it comes to coffee, this is really not the same. Blades sometimes negatively affect the taste, especially with espresso. But with spices with blory-coffee grids really your best, cheap and fast option.

Here is a short video about a coffee grinder for spices Cuisinart SG-10, which perfectly grinds most spices.

The best.Selling Krups F203 is available at a price of less than 20 (depending on where you buy), and in fact it is advertised as a coffee grinder for spices, and not vice versa.The reasons to purchase such a coffee grinder for grinding spices are simple.

If you want to experiment with grinding various spices, the Krups F203 spices are cheap enough, and if your experiment fails, you will receive only 20, not 100 or more.

If you are a chef, most likely, you are still going to use one of these mills worth 20 to grind spices, because they are damn effective and we have not seen super-expensive mills for spices there. Who do work better.

The seasonings that Krups F203 buyers have successfully grinded: flax seeds, cinnamon, nuts, rice, oats and everything that can be less solid or hard than coffee grains (and coffee grains themselves are quite hard). It can also be used to grind herbs.

Since the Krups F203 blade is so low in the case, this makes it a more effective chopper of almost everything that you throw there.

Of course, there are several coffee grounds for coffee / spices on the market, so the Krups F203 is not the only one in this ability, although it is very popular among thousands of customer reviews that sing it.

Another coffee grinder model that is great for grinding spices. Kitchenaid BCG211OB (in the photo below).

Some other important general issues that you want to ask regarding the grinding of spices include:

make, corner, grinding, opportunity, which, direction

  • What exactly are you grinding here. It will probably smell bad or difficult to clean?
  • How easy it is to clean the coffee grinder?
  • Material: stainless steel or plastic?
  • Are you going to use this for coffee or other tastes later?

Shock spices with coffee mills

As for coffee grinds, they can also be used to grind chosen spices.It is obvious that there are restrictions on the size of electric grinding machines with blades, and you must keep in mind that this time you will polish the burrs instead of blades.

Grinding with burrs changes the game a little. Take a coffee mill, such as Hario Skerton, one of the most popular grains of millstones available today. You must remember that, since this is a coffee grinder, this is not the same as a mill for spices. Zornova is specially designed for grinding coffee, although the bottom line is that yes, with some spices they work.

Here is a list of spices that are well crushed with Skerton and, probably, with other mills, although we recommend that you be careful not to break it:

  • Berries of fragrant pepper
  • Cinnamon (although it is not easy and can break the coffee grinder)
  • Cardamon seeds
  • Carain seeds
  • Oregano
  • Salt is large crystalline
  • Wheat berries (again, another tough, risky, but already made)
  • Rice (difficult, risky, but feasible)

In general, the coffee grinders are not designed specifically for spices, but for this reason you can definitely benefit from them.There is another option for spices that we have not explored.

How to work a corner grinder?

So, you bought a suitable “corner grinder” and discs to it. There is no work experience, the tool is dangerous and approaching it is scary. And you have to work. What to do? First of all, you need to take care of the protective equipment. At least you should protect your face and hands. The mask is convenient in that it protects the lower part of the face, but it fogs with a deep sigh. Glasses of this drawback are deprived, but the nose and mouth remain open for sparks, so it is advisable to use the respirator along with glasses.

Means of protection

Attention should be paid to the quality of fastening the mask to the straps. Usually this mount consists of screws with plastic lambs, which must be tightened as much as possible. It is very inconvenient when the mask dangles and falls off when bending forward.

The mask can be made of plexiglass or polycarbonate. The second option is preferable, because polycarbonate is much stronger than a plexiglass. The fragment of the scattering disk will break through the plexiglass immediately, and the polycarbonate, although it will be punched, the disk fragment will delay. Whether the damaged mask can withstand the repeated hit of the fragment, it is difficult to say. It is better not to experience fate and acquire a new means of protection.

It should be borne in mind that complete protection cannot be obtained from either the mask-shield or from the glasses. Sometimes sparks fly along a completely incomprehensible trajectory and fly under the mask, and sometimes, oddly enough, and under glasses (probably sparks fall into small gaps, which are formed between the frame and body surface during movement). Another feature of cheap plastic masks and glasses is vulnerability in front of sparks: it is worth catching a sheaf of sparks, like plastic becomes matte.

It makes sense to purchase a transparent mask with a head protection or even a welding mask. There are closed masks with a respiratory filter, which is a labyrinth of bulkheads (a fragment, getting there, spends all the inertia into ricotes between the walls).

The best protects the backfall mask. Army gas masks of the old model protect the eyes with glass eyepieces, which are not terrible sparks, but the viewing angle is too small for comfortable work. Modern gas masks with a panoramic mask is much more convenient. Unfortunately, such protection is not cheap.

Gloves as a means of protection

Gloves should be selected for a suitable size, so that there is no empty space on the fingertips on the fingertips. If the hand is close to the disk and the dangling tip caught on the rotating disk, you risk missing the moment when it is not too late to remove the hand, the less the “angular grinder”, the more relevant this problem. If the glove is perfectly sitting on the hand, the maximum that threatens you is to cut on the edge of the rotating disk.

How to Cut Tile With a Grinder Professionally

The glove from the cut will not save, but minimizes the damage. Gloves are also useful because when working with leaf metal, the edge of the cut is sharp as a razor, and a careless cut of the cut without gloves threatens with a deep cut. The metal heats up from friction, and you can burn yourself on the just cut workpiece, if you do not use gloves. Clothing should not fetter to move, but nothing should hang. Shoelaces, ties, ends of the belt or wide sleeves angular grinder will tighten so quickly that you will not have time to understand anything. The problem is that, having tightened clothes, the tool is selected to the body, and it is not at all the fact that by this moment you will have time to turn off the motor.

Long hair must be assembled in a bunch or tail. Ordinary clothing can light up when sparks hit, so it is recommended to put on a dense apron for locksmith work on top of clothing or a special overalls soaked in fireproof composition.

In general, when working with a dangerous protection tool, there is little protection. The above complex of protective equipment can be supplemented with shoes with a metal footman to protect the feet from the fall of disk fragments. You can build a real iron chain mail using the experience of reconstructors of historical battles. Chain mail protects well from large fragments, but it will let sparks pass. The same applies to masks made of metal mesh.

To the one who spends a lot of time with a “corner grinding” from a “corner grinder”, soundproofing headphones or Berushi will be useful. After a multi.Hour work, the ringing in the ears will stand for several days, and doing such work constantly, without resorting to the protection of the ears, you can easily ruin the ear.

Working with corner grinding

The “corner grinder” itself is provided with minimal protection. Actually, she has one thing for protection: a casing installed on a gearbox and closing half of the disk. This casing should be turned in such a way as to protect the master from sparks and disk fragments when it breaks. An additional handle is placed above this casing to avoid contact of the hand with the cutting edge. There is a technical ability to install the handle on the opposite side of the casing, but then the hand will be in dangerous proximity to the working area, which is fraught with serious injuries.

Of great importance is the correct installation of equipment. Different masters put abrasive discs in different ways: some-a label to the gearbox, others-label outside. Beginners often have a question, which installation option is correct? Meanwhile, due to the absence of teeth, the direction of movement of the edge does not matter. True, there is one nuance. The landing hole of the abrasive disks frames a metal ring, which, according to the manufacturer, should take on part of the load with the flange self.Loading. Usually put the disk so that this ring is under the flange.

How to avoid self.Tightening of a flange ?

The flange self.Tightening is possible when the disk is jammed, when the disk and the flange dull to it stop, and the spindle continues to rotate.Self.Elimination also happens at a sharp start, when the flange and the disk remain in place in place, and the spindle makes a breakthrough. Sometimes the flange is delayed so that attempts to free the fastening lead to a breakdown of an open key, a stop button (it is plastic and therefore very fragile) and even a gear casing.

You can avoid self.Addicted by putting a puck under the flange. You can find a suitable metal washer, or can be cut from plastic, cardboard or even paper. A very good solution would be a puck of rubber: with a prolonging jerk, it stretches, and after the downturn of the voltage returns to the previous position.

Naturally, when using proprietary mechanical soup.Ups (Bosh, Makita), the problem of self.Addication ceases to be relevant. True, new problems appear. For example, forgetting to press the folding bracket, you risk hooking it with a workpiece or a workbench, which will lead to irreparable damage to the fast.Packed mechanism.
