Circles for polishing on a grinding machine

Grinding machines can be found in many workshops. These devices allow sharpening and polishing various parts. At the same time, various types of grinding circles are used. All of them differ in the type of abrasive material, dimensions, hardness indicators and degree of graininess. Today we will talk about the features of these circles.

Features and destination

Circles for grinding electric machines allow us to simplify polishing processes as much as possible and at the same time get the highest quality result. These grinders are intended to remove a certain amount of material from the surface of the processed structures.

This method is removed unevenness, sharpening of various devices are performed.

Some types of work sometimes require special grinding wheels with non-standard configuration and sizes. Other models, they will vary with graininess, shape. Most often, similar polishing products are used for full configuration of factory equipment.

Views and sizes

The main requirement for the material that is taken to create these circles is The presence of abrasive parameters. At the same time, they must have good mechanical strength. Quality models will not collapse and deform under the influence of an aggressive environment.

All grinding circles depending on the material from which they are produced, can be divided into several separate species.

Felt

Special extruded wool is taken as raw materials for the production of such products. This is a fairly efficient grinding method, which is ensured by the special protein nature of the material used, which is used on an electric sharpener. Wool fibers are saturated with keratin, it provides interaction with the most different components of the tools processed.

These polishing circles can also be divided into 3 separate groups:

  • coarse;

  • thin;

  • semigrushrests.

The most durable and durable models are created from dense bases. In the production process, woolen components are careful processing and hardening, which allows you to make products as hard and durable. It should be remembered for some important rules for circumstances. If they are not used for a long time, then you need to cover them to reduce the risk of scratches and chips on their surface. It is also recommended to deteriorate the circles as much as possible after each application. During rotation, you can bring a pumose to it, it is not worth putting too much. Various additives and pastes use no need if there is no sharp necessity.

Vulcanite

These varieties are intended for pure polishing and grinding of metal structures. They allow you to remove the whole rusty layer from the tools and give them shine. The composition of such circles includes a special superproof tires, which is vulcanized during the production process. Special abrasive material is added to this component. Vulcanized base has excellent heat capacity.

Such products can be both flexible and hard.

Felt

Such varieties are used at intermediate processing stages before finishing polishing. Felt itself is a rather thin tissue basis that has good density. It allows you to get rid of even the smallest irregularities available on the processed structures. Before use, the felt base should be mounted as a special fluid.

Poropolone

These grinding circles are made from polyurethane base. All of them are classified into several separate groups, each of which has its colors and shape.

  • So, Black Models are designed to process surfaces that are covered with paints and varnishes. They have a rather soft structure.

  • Blue Models have an average hardness level. They are used at intermediate stages of processing.

  • Orange Circles have an average rigidity rate, increased density and good elasticity.

  • White Products are made of hard and durable foam rubber. They should be used for initial rough grinding.

Foam samples can have either smooth or relief shape. The first option may contain small abrasive particles, it makes it easy to remove scratches on smooth surfaces. Often smooth models are used to clean ceramic tiles. Relief products for grinding have an inhomogeneous working part, they contribute to the cooling of electrical equipment in the process of long polishing.

Abrasive

These polishing circles are used for medium and coarse processing of metals, wood, concrete and plastics. Such products may contain particles of various origin. Most often a grenade is used, which is natural material, it differs in the greatest flexibility, elasticity, such a component is best suited for wood processing. And the circles may contain particles of silicon carbide, which is considered high strength and reliable material. It can be perfectly able to approach rough polishing of metal, wood and plastics. Ceramics elements allow you to cope with large irregularities on the surface of the processed structures.

Aluminum oxide is used to conduct delicate polishing works. It will not leave small dents and scratches on products.

Circles for grinding machines can have different dimensional values. But the standard variants are considered models 125 mm, 150 mm, 175 mm and 200 mm in diameter. Landing is most often 32 millimeters. Product thickness may vary from 10 to 25 millimeters.

How to choose?

Before you purchase such a circle for polishing, you should pay attention to the most significant nuances of choice. First look at the composition and material from which the sample is made. After all, each individual model can be intended for coarse, medium, intermediate polishing. Some varieties apply only for delicate processing of smooth or lacquered surfaces.

In addition, individual samples are used only for processing plastic or wood, metal, exist products and for sharpening drills. There are special sharpening varieties for drank, their edge is formed at a small angle, it allows us to provide ease of treatment between teeth.

And also before buying it is necessary to pay attention to the size of grinding circles. In this case, the choice will depend on the dimensions of the parts, which further need to be processed, as well as from the size of the sharpening equipment itself.

Consider the degree of grain of the circle. These sharpening parts may have different grains, it is indicated by the following values: 8H, 12H, 16N, 25N, 40N. And the more the number will be, the greater grain, rougher grinding and polishing parts.

It should be viewed on the shape of these polishing nozzles. Preferably there are models in the form of a cup, plates or a simple straight profile. The choice in this case will depend on the type of work performed, as well as on the form of the material that is required to be processed.

If you select such a disk for polishing and grinding the metal, then look at its colors. So, white samples are intended for sharpening a simple steel base, shovel, kitchen knives, axes. They are labeled A25.

Often, manufacturers add special pigments in the manufacture of these circles, as a result they can purchase a blue or orange shade. During the operation of a simple metal on such a nozzle, the most high-quality sharpening will be obtained, because the composition of the product itself is quite soft, the temperature values ​​are small at friction, so blue scale will not appear on a metal basis.

Models having green colors are used for sharpening carbide structures. They are often taken to process drills for metal, knives intended for woodworking work. They possess marking 64c. It should be remembered that When working with these varieties on the metal, dark scale may appear, since in this case there will be a rather high temperature indicator.
