Do.It.Yourself grinder: how to make a grinding machine with your own hands

There are many options for applying for homemade grinder in the household. It is not only about a private house or a personal plot, but also about housing in an apartment building. With its help, you can process any surface.

The degree of purification depends on the type and used abrasive materials. Unlike industrial models, a device assembled with your own hands will be favorably different in cost, since the budget of the design will only depend on the master.

Possessing locksmith skills and basic knowledge in electric business, you can easily assemble the device yourself.

Principal grinding machine

Without thorough knowledge of the design of grinding machines, it is impossible to assemble a high.Quality device with your own hands. Before moving on to the structure, we will get acquainted with the most common types of grinds:

  • Corner. Simply put, corner grinder. Consumables are discs. Feed circles are designed to grind the surface. Pressure adjustment is carried out manually.
  • Ribbon. Surface treatment is performed with a grinding tape. Suitable for work only with flat surfaces.
  • Deltas.Grinder. For processing products with a curved structure.
  • Vibrational. Optimally suitable for finishing the processing of even planes.

In addition to the above, there are several more devices that are less common:

Regardless of whether the device is a factory or assembled with your own hands, the main elements of the design are:

  • Drive unit. The productivity of the device depends on its power. In the devices assembled by yourself, an electric type is used, however, there are pneumatic homemade homemans that work from the compressor.
  • Gearbox. Transfers torque from the drive to the working tool. The base part of the gearbox is a spindle.

The gearbox is an integral part of tools such as corner grinding or drill. Some models, especially with your own hands, do without it.

  • Working platform. Abrasive material is attached to it. To do this, you can use circles, ribbons, discs.
  • Frame. Protects the structure from mechanical damage and dust, so many factory models are equipped with dust system systems. Materials used for the manufacture of the device with your own hands, as a rule, are not able to compete with high.Quality polymers that are used in the production of professional tools.
  • Control system. Includes the power outage, as well as the adjustment of the revolutions of the abrasive.

Home.Made design options

It is not difficult to make a grinding machine with your own hands. The main thing is that it corresponds to the types of works that the master plans to perform. From an economic point of view, it is better to take components at hand.

If the components of the device must be bought, then the budget of the device made by yourself will be comparable to the factory model.

All other things being equal, it is better to give preference to an industrial tool, because its quality is incommensurable higher.

Consider several do.It.Yourself devices. Perhaps one of them is suitable for you.

DIY grinder

As the name, the corner grinder is designed for grinding. Feed discs successfully cope with rough work: removing the old paint, removing the influx of metal or traces of corrosion. For a thinner cleaning, special nozzles from an sandpaper of various grainness are sold.

Models for domestic use work in one mode, and the number of revolutions reaches 15 thousand. Per minute with an average indicator of 11 thousand. This speed is great for sawing materials, but for grinding work it is great.

The angular grinder motor has excessive power. 300-400 watts will be enough for polishing.

A grinder made of corner grinder will have a large weight compared to the factory tool, but it is possible to adapt a homemade for itself, which will increase comfort when grinding.

For angular grinder, you can make a simple nozzle that will turn the device into a miniature tape-grinding machine. In this case, the work is performed without a protective casing.

If there is no desire to use the device, you can adjust the number of engine speeds. Independent modernization of the scheme will require specialized knowledge in electrical engineering.

On professional devices, you can set the number of revolutions manually, however, their cost starts at 200.

We make a grinder from a drill

With your own hands, you can assemble a productive tape-grinding machine. In this case, the tool acts as a drive. The design itself is simple and does not require significant investments. The following materials will be needed for your own manufacture:

  • Metal rods with and without and without it;
  • Profile pipe;
  • Plywood;
  • Steel sheet;
  • Bearings;
  • Metizes;
  • The carpentry glue.

You should take care of the presence of a locksmith tool, inverter and devices for sawing metal.

  • Production of pulleys. Leading and driven pulleys are designed to transmit torque from drill to slices. They are made from plywood.
  • The diameter change can be obtained the right torque. One pulley consists of several rounds that are connected using carpentry glue. In the center it is necessary to drill holes for steel rods. After the glue dries, the workpieces are finalized, making a groove that must correspond to the width of the drive belt.

For small and accurate work, it is better to purchase compact nozzles of drum or plate type, depending on the type of work.

Homemade grinder from computer hard drive

A small grinding device can be assembled from the old hard drive, the main advantage of which will be the complete absence of investments with the exception of the costs of abrasive circles. The process of manufacturing with your own hands looks as follows:

  • We open the case and remove all the elements located next to the magnetic disk.
  • In terms of the size of the upper part of the drive, we cut a circle of sandpaper the desired granularity.
  • Using double.Sided tape, we fix the paper on the surface of the disk.
  • We make a casing that protects against dust or abrasive grain.
  • To start the design, the hard drive must be connected to the computer power supply.

What is required for the manufacture of a mini-grinder

The nozzle described today for an angular grinder turns a corner grinder into a mobile grinder, which allows you to perform operations with small details. It will require a minimum of material for its manufacture:

  • Strip metal 4 mm thick;
  • Profile pipes with sides 15 × 15 and 20 × 20 mm;
  • Bearing (inner diameter 8 mm);
  • High nut with a thread 14 mm.

The tool will become clear during the article. The only thing can be said that everything can be found in almost any garage.

Grinder from grinder: a simple way to make with your own hands

Very often, for various works, the home master requires precisely Grinder, especially if it is necessary to do small work or crawl into hard.To.Reach places. But it makes no sense to purchase a mini-grinder for one-time work. It is much easier to make a nozzle on a corner grinder with your own hands. The author of the YouTube channel Mikhail, who collected such a nozzle from improvised materials that can be found in almost any garage or workshop, offers its version of the solution of this issue.

Making the base for the nozzle for angular grind

The main task at the first stage is to correct the metal strip correctly. It should approach the angular grinder in diameter, namely to take the place of the gear clamp.

Bend it to the desired shape with any suitable pipe. However, the ring should not fully fit the circle. A place is necessary for a profile pipe, which will subsequently be welded to it. How everything should look in front of the welding stage, you can see in the photo example.

Clamp for angular grinding pipe on a profile pipe

However, a similar ring will not be clamped on a circle, which means that you need to make some kind of clamp. To do this, it is necessary to drill a profile pipe through the welded steel ring in the area. Next are the tapes (one along, the second across the profile pipe). Perhaps in the text it is difficult to understand the location of these cuts, and therefore we will show by example.

Now it remains to make a thread on one side of the drink, and expand the second hole. It turns out that when the bolt is screwed into the thread, he will be able to reduce the circumference of the clamp by the width of the cut. At this stage, it is worth checking whether the clamp is clamped well. If the structure hangs out, the width of the cut should be increased.

Longitudinal pipe and its purpose

The transverse pipe is ready, but now you need to weld the longitudinal to it, which will serve as a support for the sandpaper tape. She should go exactly in the middle of the leading video (we will dwell on its manufacture later).

After the longitudinal profile pipe is welded into place, you can cut off excess, drown out the hole from the end and clean all the seams. So the product will look much careful.

How to make a grinding machine

Когда работа с деревянной поверхностью подходит к завершению, наступает этап финишной шлифовки.

To make grinding without burrs, scratches, beautifully round the sharp corners of any details, you need to use a grinding machine for wood.

This tool will help to make grinding professionally even a beginner who first took the device in his hands. If you have a desire, you can make a grinding machine yourself, using only improvised means.

The industry produces several types of machines that differ both structurally and as intended. Here are the main ones:

  • Eccentric or orbital, in this case the sole of the tool simultaneously rotates around its axis and in some orbit. It turns out that each time it passes a little in another place, so the scratches and burrs are rubbed with each passage more and more.
  • Vibration model. Here the working sole carries out reciprocating movements with a frequency of about 20,000 movements per minute. It is due to these movements that grinding.
  • Corner grinding machine, which is popularly called “corner grinding”. Using this tool, rough processing of parts, large logs, etc.P. For processing, abrasive circles of the necessary granularity are used.
  • Ribbon grinding machine, which is usually used for work on large surfaces. Structurally, it is rollers driven by an electric motor, which is worn by an sandpaper.

DIY tape grinder

It is not at all difficult to make a tape grinder on your own, it is necessary to perform the following stages:

  • Choose suitable materials and details;
  • Make a reliable basis for fixing the tool;
  • Install a suitable countertop;
  • Fix vertical racks with a tensioner and a drum;
  • Mount the motor and drums;
  • Fix the sandpaper.

To process rather large details and elements, it is necessary to make a large copy of the serial grinder. For example, if you take an electric motor with a capacity of 2 kW or more powerful with a rotor speed of 1500 revolutions per minute, then the gearbox can not be placed. The power of such an engine is quite enough to rotate the drum about 20 cm in diameter and process parts about 2 m.

You can also use an electric engine from an old washing machine. In this case, the bed is made of a thick sheet of iron, preparing a place for installing the motor and carefully fixing it with bolts to eliminate vibration. The design of such a machine is 2 drums, one of them is fixed, and the second can be pulled and rotates on bearings around the axis.

It is advisable to make the basis for the machine from metal or several sheets of thick plywood. Drums are made on a turning machine made of woody stove. The tape is cut from the paintings of sandpaper about 20 cm wide and fixed on the bed. The larger the dimensions of the table, the larger the size of the parts can be laid and processed in the future. Drawings of finished products can be found on the network.

We make a grinder of corner grind

It is possible to make a good grinding machine from the corner grinder, which is not inferior in its parameters by the factory typewriter, only by finalizing its electrical circuit, by installing the regulator for lower revolutions and by using special grinding nozzles.

We make a grinder from a drill

The support or grinding plate is a plastic or rubber base with glued sandpaper and a shank for a clamp in a drill cartridge. Plates with a flexible shaft are suitable for working with an untouched drill, and with hard it is better to use only for a well.Fixed drill.

Grinding drums for a household drill constructively are a regular cylinder, shank and sandpaper glued to the cylinder. When using drums, the working surface of the grinder is located parallel to the axis of rotation.

We make an orbital grinder

Currently, you can make an orbital machine with your own hands only from a broken orbital machine. This is due to the complex device of rotation of the working disk, which is quite problematic to repeat on your own. It should also be borne in mind that the machine made by a specialized company will not cost too much, and it will be very difficult to make it with your own hands and will take a lot of time.

We make a grinder from computer hard drive

Anyone who has served their hard drive can be converted into a miniature grinding machine. To do this, you need to perform the following steps:

  • Completely disassemble the hard drive and remove everything that is located on the left of the magnetic discs;
  • Cut the working circle of sandpaper, make a hole for the spindle in the center of the circle;
  • Glue a few stripes of bilateral tape on the hard drive rotating disk and fix the sandpaper on it;
  • Make a protective screen that protects the eyes from the possible departure of the made sandy disk;
  • Connect the finished design to the power supply from the computer and use.

We make ourselves a tape grinding machine with our own hands

When working with a tree, the final stage of processing the material will be grinded. A grinding machine will help you with this. There are many different models on the market, but if your budget is cracking at the seams, such a machine can be made independently.

How to make a grinding machine

You can make a simple machine from the hard disk of your PC. To do this, you will need a hard drive itself, abrasive, PC power supply. It will be intended to work with small details. When disassembling the disk, you should stick an abrasive on a rotating plane. After that, the structure must be connected to the PSU (power supply), and then fix the entire structure on the working plane of the table, supplying the revolutionary control regulator, the switch.

DIY grinding machine

Grinding machines are represented by the following views:

In the manufacture of the machine, you will need:

The power unit must be taken from household appliances, for example, from a fan, a power supply. Computer, battery. Household. A wooden board on which screws should be fixed with an electric motor is suitable as a base for the above elements. The “Start” button must be attached to the base with self.Tapping screws. The wire veins are fixed using an industrial stapler bracket. The work detail of the tool is a grinding circle, which can be purchased independently. The abrasive disk will be driven using an electric motor using two bushings. You can strengthen the design of the device if you take the engine from the washing machine as an engine. In addition to polishing discs, in this case, we can install sharp and abrasive on the tool.

Homemade tape grinder

As a working element in this type of devices is a grinding tape from an abrasive. Do.It.Yourself machine will be stationary, and have large dimensions compared to the industrial model. For the manufacture of a sample, it is best to use a 2-3 kW power unit and a rotor speed of 1500 rpm. The radius of the leading drum directly affects the speed of moving the tape. The larger it is, the higher the speed of the tape is higher. The home.Made design will not allow you to adjust the speed of the tape, however, you can influence the tension force by shifting the motionless axis of the tension shaft mounted on the engine shaft regarding the desktop. The workbench for a grinding machine should be made of wood or metal. A tape for a grinding machine can be made of abrasive paper sold in a construction store. The working element, which is the sandpaper, is set in motion using the transmission and drums with a power unit. Shafts are divided into leading and led. Drums can be made using sheets of a wood-steering plate, processing them on a lathe so that as a result of processing there are about 20 cm disks in diameter. When processing, one thing should be taken into account: the edges of the shafts are required to have a larger diameter compared to the central part, to automatically hold the tape. The dimensions of the rack will depend on the width of the tape and the distance between the shafts. At the location of the shafts in the canvas, it is necessary to make slots for smooth passage of the tape.

How to make a mini.Grinding machine with your own hands

First you need to find foam to prepare the basis for the device. After that, you need to cut a hole for installing a circuit breaker in it. Then you will need an island and a power source, for example, a well.Known Crohn battery. We hug a power battery (crown) to the foam base with island. We take a champagne plug and a handle rod. Cut the rod to the desired length, then put the handle rod on the cork with a blunt end and insert the edge of the rod into the hole for the shaft of the motor. After that, you need to cut the strip of abrasive tape under the dimensions of the cork dimensions. After you cut out the tape, it should be glued to the cork around the circle. This design is made of traffic jam and will be the working part of the machine. Carefully examine all the wires and connect them with twisting, isolate the connections with electrical. Try to start the resulting device. Now you have your own mini machine. Such a device is useful for performing simple small works, for which the usual grinding machine will be too large and uncomfortable. If you are an observant and patient, as well as a reinforcing person, it is completely easy to make a grinding machine with your own hands. To do this, you only need dexterous hands and a little patience.
