Characteristics and Choice of Grinding Wheel

The grinding wheel from Grinding Wheel Supplier is the most important type of grinding tool in grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, strength, bonding agent, hardness, organization, shape and size.

(1) Abrasives

Abrasive is the main component of the grinding wheel from Grinding Wheel Exporter. It has high hardness, wear resistance, heat resistance and certain toughness to withstand the cutting heat and cutting force during grinding. At the same time, it should also have sharp sharp corners for profit. Grinding metal. A summary of commonly used abrasive codes, features and application areas.

(2) Particle size

Particle size refers to the size of the abrasive particle size. The particle size is divided into two types: abrasive grains and fine powder. For abrasives with a particle size greater than 40 μm, it is called abrasive particles. The classification was carried out by a screening method, and the particle size number was expressed by the number of perforations per inch of the sieve passing through the abrasive grains.

(3) binder

A binder is a material that binds abrasive particles together to form an abrasive article.

(4) Hardness

The hardness of the grinding wheel refers to the difficulty of the abrasive grains falling off under the action of external force when the grinding wheel is working. The grinding wheel is hard, indicating that the abrasive grains are difficult to fall off; the grinding wheel is soft, indicating that the grinding wheel is easy to fall off. The hardness level of the grinding wheel is shown in Table 6.9.

(5) Organization

The organization of the grinding wheel refers to the proportional relationship between the three parts of the abrasive grains, binders and pores of the grinding wheel.

(6) Shape and size

The shape and size of the grinding wheel are determined according to the type of grinding machine, the processing method and the processing requirements of the workpiece. The commonly used grinding wheel name, shape diagram, code number and main purpose are shown in Table 6.11.
