Grinding abrasive is a material used for grinding and trimming saw blades. The following is an introduction to grinding and sawing abrasives:

1、 Common types of grinding and sawing abrasives

diamond grit 

Characteristic: It has extremely high hardness and is the hardest substance in nature. It has good wear resistance and cutting performance, and can quickly and effectively grind saw blades.

Application: Suitable for grinding high-performance saw blades such as hard alloy saw blades and diamond saw blades. Commonly used for fine trimming the cutting edge of saw blades to improve their cutting accuracy and service life.

Silicon carbide abrasive

Characteristic: High hardness, second only to diamond. Has good self sharpening ability, which means that new sharp particles can be continuously broken during the grinding process, maintaining good cutting ability.

Application: Widely used for grinding ordinary steel saw blades, high-speed steel saw blades, etc. It can remove the wear and defects on the surface of the saw blade, restoring its sharpness.

Aluminum oxide abrasive

Features: Moderate hardness, relatively low price. Has good grinding performance and stability.

Application: Commonly used for general grinding and finishing of saw blades, suitable for saw blade materials with medium to low hardness.

2、 Particle size selection of abrasives

The particle size of abrasive has a significant impact on the grinding effect. Generally speaking, the smaller the particle size, the higher the surface smoothness after grinding, but the grinding speed is slower; The larger the particle size, the faster the grinding speed, but the surface smoothness is relatively low.

Coarse grained abrasive: usually used to remove larger defects and wear on the surface of saw blades, such as notches, chipping, etc.

Medium grained abrasive: suitable for general grinding and finishing, can improve the flatness and sharpness of saw blades.

Fine grained abrasive: used for fine grinding of saw blades to achieve higher surface smoothness and cutting accuracy.

3、 The function of abrasives

Restore the sharpness of the saw blade: With the use of the saw blade, the cutting edge will gradually wear and become dull. Abrasive removes the wear layer on the cutting edge through grinding, restoring the sharpness of the saw blade.

Correct the shape of the saw blade: During use, the saw blade may deform, twist, and other situations. Abrasive can adjust the saw blade to restore its correct shape and size.

Improving the service life of saw blades: By regularly grinding and trimming the saw blades, the service life of the saw blades can be extended and production costs can be reduced.
