Grinding machine - choice and types of device

A tool called a "grinding machine", depending on its purpose, can have a different design. Therefore, you need to know exactly what kind of work it is getting. The use of such devices is necessary to remove the rust layer from metal surfaces, to grind the surface of concrete, to cut various building and facing materials and many other works. This is a power tool. According to its design, grinders are divided into angular, belt, vibrating, eccentric.

Bulgarian

The Bulgarian, or the angular grinding machine, is designed to perform operations for cutting, grinding and cleaning surfaces from a variety of materials. Due to its versatility, this is the most famous and common tool from the category of grinders. There is a large selection of instrumental disks for this unit, for each type of material - its own. This grinding machine in its performance is very dependent on the power of the device. The more complex the work will have to do, the more powerful the tool should be. Up to 900 W such machines are considered low-power, up to 1500 W - a tool of medium power. Having a power of more than 1500 watts is a powerful grinding machine.

There are one-handed and two-handed designs. Two-handed are more convenient in work, and therefore preferable. The tool is divided into the intended use for household and professional. Professional Bulgarians are designed for a long period of work, and therefore the quality of materials for their production is higher. Various attachments and additional components are attached to them. Households are cheaper.

Tape construction

The belt sanding machine is used for rough grinding of planes. It is used in finishing work to remove a thick layer of material, for example, to remove putty. It is processed parts of windows, doors, edges, curvature, and also used to repair the car. The working tool is a belt, which is a sandpaper, glued in a ring and rotating on two end rollers. The width of the belt is from 65 to 110 mm, the speed of rotation is up to 400 m / min. The higher the rotation speed, the higher the productivity of the machine.

However, such high-performance machines have a drawback. The surface after their work happens with scratches and traces of the instrument. The best professional tools are made by De Walt and Makita. Bosch manufactures both professional and household models. The Skil grinder is produced in the Dutch factories, is of high quality and is intended for use in everyday life. This company produces a large range of such tools with a good bundle and excellent technical characteristics. The same advantages are distinguished by tools from the company Black & Decker, besides they are quite affordable. They are produced in the factories of South-East Asia.

Safety precautions

When working with grinders, you should always use protective goggles. When working with a Bulgarian it is necessary not to allow the disc to be bitten by the material. You can not use for them discs that are not designed for these machines.
