Advantages of Hardness of Silicon Carbide as Abrasive

The hardness of the silicon carbide abrasive does not refer to the hardness of the silicon carbide abrasive or the bonding agent itself. Abrasive hardness refers to the degree of difficulty for the abrasive particles on the surface of the abrasive tool to resist the external force to cause the abrasive particles to fall off the surface. In other words, it indicates the strength of the abrasive wear resistance. If it falls off, the hardness is soft, otherwise the hardness is high.

The hardness of ceramic abrasive tools with particle size 36# to 150# and resin abrasive tools with particle size 36# to 80# is measured by a sandblasting hardness machine. The hardness of ceramic abrasive tools from 180# to W5 and resin abrasive tools from 100# to W5 are measured by Rockwell hardness tester.

It is also possible to manufacture some abrasive sample blocks, which can be used as standard sample blocks after being measured by the above-mentioned instruments, and the hardness can be compared and determined by the cone method. As for the rubber bond abrasive tools, there is no very suitable instrument to measure its hardness. Now most of it depends on adjusting the formula to change its hard hair.
