The main characteristics and functions of the Bulgarians
Corner grinding machine is one of the most dangerous construction tools. Therefore, manufacturers equip the corner grinder with various functions that protect both the operator and the tool itself.
Smooth start. The function provides a gradual set of revolutions. Lack of sharp vibration when turned on, avoids the loss of the tool from the hands. When connecting a grinder to the generator, a smooth start reduces the requirements for the power consumption. This significantly reduces the cost of an emergency power source.
Revolutions adjustment. Allows you to set the number of revolutions for the specifics of the processed material. This is important when grinding and polishing workpieces, carrying out cuts on wood or plastic. Proper setting guarantees the accuracy of processing and retains the integrity of the material.
Permanent electronics. Supports selected turns, regardless of the load on the tool. This is especially important when processing objects with a large profile and viscous materials, for example, aluminum.
Protection against “snacking” disk. The principle of operation of protection against “snacking” the disk is quite simple. It is based on the instant shutdown of the MSU engine in the case of a disk jacket or during interruptions in power supply. Both cases, as you know, are the most common causes of injuries when working with grinders, even if safety precautions are observed. However, using the tool with such protection, serious consequences and injuries can be avoided. A special electronics are provided in the filling of these MSU, which instantly responds to an increase in the load on the engine, as well as to a power break on the network, and turns off the electric motor. This allows minimizing the likelihood of splitting the disk when jaming the tool. After such an emergency stopping grinding, it will be possible to start work only by transferring the power switch to the position “off” and returning it to the on position. Thus, this system increases safety when working with MSU in two cases.
Vibration control. Placed in the handle, reduces the effect of harmful vibration on the operator. Especially relevant for powerful heavy bells.
Rotary housing and fast rearrangement of the casing. Some large grinders have the function of turning the case to an angle up to 90 ° and a protective casing with a quick fixation system. This saves the time of the operator and reduces labor costs with frequent tasks.
Ungle grinding machines from a professional segment have these functions. They are not obligatory, but allow you to facilitate the operation of the tool.
The main characteristic for the corner grinder is its power and what diameter of the circle it is designed. If you do not know how to choose an angular grinding machine for the house, then know that for optimal work you should choose a corner grinder with a capacity of up to 1000 watts. If you rarely plan to work for her, then you will be more than enough angular grinding with a small supply of power, so as not to overpay for the resource that you do not use.
If you buy a corner grinder for construction or production activities, then you should choose a corner grinder is more powerful, with an engine of more than 1000 watts. Such a device is much more resilient and more productive, so it can withstand large volumes of work with maximum workload.
The most running angular grinding machines are designed for the following circles:
125 circle. Such a corner grinder is the smallest and most mobile, it is easy to use, and it is easy to control when working. Such corner grinders are most often bought for domestic use, but it is not rarely bought to work in more severe conditions.
180 circle. Corner grinding machines that are designed for such a circle and productive and mobile. They are not very bulky and can perform the work of a larger volume. Applied both in everyday life and production.
300 circles. The largest circles for the largest Bulgarians. Such a tool easily copes with the most difficult work and can cut thick metal and cut out deep ditches.

Additional systems to work with tools
Corner grinding machines are widely used due to convenience, versatility and reliability. The design of the power tool provides a number of systems that are designed to ensure high performance and safety of working with the tool. The functionality of each model is determined by the manufacturer at the design stage, the list of additional options affects the cost.
That is why, then we will consider additional systems that ensure the operation of the corner grinder and determine how important their presence is for effective and safe use of the tool.
Starting current restriction system
When the electric engine is turned on, an abrupt increase in the load on the engine winding occurs by 6-8 times, which can cause damage or the operation of protection. In this case, a stroke moment also arises, which is transmitted through the shaft to the gearbox and spindle. The starting current restriction system is an electronic circuit that provides a smooth increase in the speed of rotation.
The principle of operation of this system is a gradual increase in voltage on windings for a given time. The use of a corner grinding machine at the same time becomes safe, increases the resource of the electric motor and gearbox.
The lack of a blow at starting helps to increase the accuracy of cutting and eliminates the possibility of stray when grinding.
The system for maintaining a constant number of disk speeds
When the cutting disk is in contact with the processed surface, friction occurs, which increases the load on the engine and reduces the speed of rotation. The system for maintaining the constant number of revolutions of the disk compensates for the resistance and ensures the maintenance of the cutting speed. Stabilization of the spindle rotation frequency is carried out due to the use of the constant electronic circuit.
There are two ways to maintain speeds in corner grinding machines operating under load: on the current or by the spindle rotation frequency. In the first case, a current consumed sensor is used, which fixes its value and, as it increases, the circuit increases the voltage on the windings.
Rotation frequency regulation involves the use of a tachiometric sensor that controls the turning of the angular grinder. With a decrease in this indicator, the electronic circuit increases the voltage and, as a result, provides the optimal speed of the equipment of the equipment. The choice of the methodology for maintaining a constant rotation frequency occurs at the design stage and is carried out taking into account the positive and negative sides of each method.
Not all models are equipped with such a system, we can say that its presence is desirable, but not necessarily.
Re.Inclusion lock system
During the construction work, a situation is possible when the power is turned off for a variety of reasons. The system for blocking the re.Turning on the corner grinder excludes the possibility of unintentional engine start. With a sudden stop of the corner grinder, the employee most often simply puts the tool to the side, without checking the position of the circuit breaker.
The sudden resumption of energy supply in this case is fraught with injuries for the contractor or damage to valuable property. For the Bulgarians equipped with such a system, re.Switching on occurs only after disconnecting the starting device and its re.Press. In this case, the user will need to take the tool in his hands, which means that his actions will be meaningful and controlled.
The presence of such a system is very important and necessary.
Disk automatic balancing system
In the process of use, corner grinder, especially with the equipment of a large diameter, wear of the disks or brushes occurs unevenly. This leads to the occurrence of an imbalance, which manifests itself in the form of vibration, which does not contribute to the accuracy of the operation. The beating adversely affects the condition of the bearings and reduces the resource of the electric motor.
The automatic disk automatic balancing system compensates for the uneven distribution of the mass of rotating equipment. Different technical solutions are used to stabilize the tool, mostly these are special design of bearings with fewer balls. This system will increase products and is usually used on professional models with large diameter disks.
If you choose a tool for intensive use on the construction site, then it is best to give preference to models equipped with this system.
Engine protection system from overload
In the process of use, the angular grinder load on the electric drive is inconsistent and in certain periods can significantly exceed the calculated. To protect the engine from overloads of the “corner grinding” are equipped with special systems that forcibly stop supplying current. In this case, the tool simply stops working and for renewal it is necessary to turn it off first, and then turn it on again.
There are two ways to protect angular grinding machines from overheating: by current or temperature. In the first version, the shutdown occurs when the limit parameters are exceeded, which are fixed by the electronic module. Another design on the engine is installed a temperature sensor that interrupts the power circuit when the parameter exits the set values.
The system provides the highest life of the tool but does not affect the quality and safety of the work.
Dust protection system
In the process of grinding surfaces or cutting materials, a significant amount of dust is formed using an angular grinder. It enters with the flow of air into the case and serves as the cause of increased wear, the most vulnerable bearings, brush node and the outer surfaces of the rotor and stator. Metal particles formed during cutting can cause a short circuit between the turns of the winding.
The system of protection of the angular grinding machine provides for the use of the following structural and technological solutions:
- Installation of nets on ventilation holes, and on expensive professional models and filter elements.
- Booking the stator windings and the use of cord bandages on the rotor.
- The use of closed type bearings.
- The gearbox body is done if possible airtight.
- Pouring windings with epoxy resins.
The main selection criteria for corner grinder
What is she. An ideal angular grinder? It all depends on the goals for which you want to choose it. We recommend focus on the main parameters:
- Maximum size of cutting disk;
- Engine power;
- Number of revolutions;
- Ergonomics, ease of work;
- The presence of additional functions.
The maximum diameter of the cutting disk of the angular grinding machine indicates how deep the gap will be. Remember that the greater the maximum diameter, the higher the power of the motor should be.
Example: For a corner grinder with a 125 mm cutting disk, you need a 750 W engine. For a 230 mm disk-at least 2200 watts.
The speed of the corner grinder is also closely related to the size of the equipment. For example, a corner grinder with a circle of 230 mm cannot have more than 10,000 revolutions per minute. This rule is saved: the larger the circle, the more revolutions, and the engine should be more powerful.
Ergonomicity and convenience in work understand light weight, comfortable handle, the ability to work angular grinder in different positions. Everything is very individual here. But it will be better if the corner grinder is equipped with an additional removable handle. She will help out more than once.
The main characteristics of corner grinding machines
When you come to a construction supermarket, to a profile tool store or just to the market to buy a corner grinding machine, the first question that you will be asked. You need a professional tool or for yourself. Professional corner grinder is designed for daily operation for several hours a day. In order to facilitate the work of the master and extend the resource of the unit, it is equipped with enhanced dust protection, all kinds of electronics, design features that reduce the noise level, and adjusting the speed of rotation of the disk.
The corner grinder “for yourself” belongs to the category of household instrument for a home master, who will use it episodically, when something suddenly breaks or does, or no more than 30. 40 minutes a day. Household corner grinders have less power and require work with interruptions. For example, 15. 20 minutes of work and 30 minutes of rest. During this time, the engine manages to cool down and the probability of failure is less.
When choosing a corner grinding machine for home repairs or professional activities, it is necessary to understand exactly what specific work it will be used. Already based on needs, the diameter of the disk, the speed of its rotation and the power of the corner grinder are selected.
Diameter of the disk of corner grinder
The diameter of the disk is angular grinder is the main parameter, which must be focused on when choosing, the power of the unit and the speed of rotation of the circle is selected taking into account the diameter.
There are corner grinders under discs with a diameter of 115 mm, 125 mm, 150 mm, 180 mm, 230 mm. The simplest angular grinder with a disk diameter 115. 125 mm are domestic, they can be used for grinding various surfaces, removing rust, paints from parts, for polishing, as well as for cutting various metals and ceramic, granite tiles, the thickness of which does not exceed 50 mm. The main restriction in cutting is the thickness of the material. The disk of small diameter will not work to cut a concrete border or another massive element. But for home needs, a 125 mm angular grinder is more than enough.
A 230 mm angular grinding machine belongs to a professional tool, 180 mm can be attributed to the same category. Such powerful units are used to cut massive concrete products, asphalt, stone, brick. Huge power, heavy massive disk, large vibrations make it meaningless to use angular grinder with a 230 mm disk diameter for cutting a thin corner, sheet iron, tiles, plastic, as well as for grinding and polishing surfaces. This is easier to make a less powerful and weighty unit.
The power of the corner grinder
The spread of capacities into the corner grinder is very large: from 600 watts to 2700 watts. Corner grinder with a disc 115 mm are 600. 1000 watts of power, more simply meaningless.
Corner grinder with a disk of 125 mm have a power of 750. 1500 W. As a rule, low.Power units from a series of 125 mm have a small number of additional functions and are not intended for long.Term use. Corner grinder with a capacity of 1200. 1,500 watts is usually crammed with all kinds of useful functions and elements.
How to adjust and operate a G131 Corner Grinding Machine
Corner grinder with a circle of 180. 230 mm belong to multi.Power units 1500. 2700 watts. To cut concrete, stone and other massive elements, you will need an angular grinder with a capacity of 2000 watts. But for cutting small parts, sheet metal, plastic, for grinding and polishing, an angular grinder with a capacity of 720. 1000 W is suitable. If the corner grinder is bought for home repairs, but for difficult work, then it is better to take an angular grinder at 125 mm with a capacity of 1200. 1500 W.
The greater the power of the corner grinding machine, the longer it can work under load. Power is selected taking into account the complexity and duration of work, the weight of the disk that you are going to use. For example, if it is planned to clean the welding seam with a 115 mm corner grinder, then you need to take an unit with a capacity of 1000 watts. If it is planned to use 230 mm heavy disks, which are not so easy to promote, then the power will take from 2000 watts.
The speed of the disk on the corner grinder
The speed of rotation of the disk or spindle on which it is planted shows how much revolutions per minute he makes. The greater the disk is set, the less speed it is necessary.
The speed of the disk rotation to the corner grinder occurs from 2800 rpm to 11000 rpm. Small circles 115. 125 mm are used at a maximum speed of 10. 11 thousand. Rpm. But for 180 mm circles there is already a limitation of 8500 rpm, and for circles 230 mm. 6650 rpm. These restrictions are due to the fact that the linear speed of the cutting edge of the disk should not exceed 80 m/s, otherwise the disk may fly apart by crippling the master.
Important! It is better to purchase a corner grinding machine, which has the ability to adjust the speed of the disk, depending on the size of the disk used. Most often it is implemented using a special lever or regulator.
Recall that the size of the disk indicated in the marking is the maximum permissible. For example, in a 150 mm corner grinder, you can put discs 115, 125 and 150 mm.
