Components And Characteristics Of Roll Grinding Wheel

The roll grinding wheel adopts new ceramic abrasives and newly developed bonding agent, and its performance far exceeds that of previous ceramic abrasives. Even if the material based on the grinding wheel is difficult to cut, these abrasive particles are less likely to cause the welding phenomenon on the top of the cutting edge, and can be used to increase the margin with a large and high efficiency.
In addition, the roll grinding wheel can greatly increase and reduce scratches, and greatly improve the surface quality of the roll.
The roll grinding wheel is mainly composed of three parts: abrasive, binder (bonding agent), pores
The following is a detailed introduction to these three materials:
1. Abrasive: is the main grinding part of the roll grinding wheel, with sharp corners, that is, small cutting edges, used to cut the workpiece, said abrasive is a material that is often very hard, usually a compound, such as silicon carbide (silicon carbide Chemical composition), corundum (chemical composition is the oxide of aluminum), diamond, corundum grinding wheel and corundum grinding wheel are the most common at present.
2. Binder: According to the different purposes of the enterprise, the roller grinding wheel is classified into ceramics, resin, rubber, metal, etc. Its main function is to bond the abrasives together to form a grinding wheel with a certain structural shape.
3. Pores: Pores are also the main component of the roller grinding wheel. The purpose of the pores is to reduce the bonding strength of the binder and store the grinding steel shavings. When the sharp parts of the small abrasives are worn out, the pores will cause The bonding strength is reduced and peeled off, exposing new sharp abrasive grains, which is beneficial to further grinding.
3. Pore: Pore is also the main component of the roll grinding wheel. The purpose of the pores is to reduce the bonding strength of the binder and store grinding steel shavings. When small abrasive sharp parts wear, they peel off due to porosity, resulting in a decrease in bond strength, exposing new sharp abrasive particles that facilitate further grinding.
Features of Roll Grinding Wheel:
1. Good cutting sharpness
2. Long service life of grinding wheel
3. High grinding efficiency
4. Short grinding time
5. Good surface roughness
6. Good sense of operation
7. Less vibration pattern
