What factors affect the hardness of grinding tools

Grinding tools are products that are needed in many industries, and their hardness will affect the specific usage and application areas of the tools. So, what are the main factors that affect the hardness of grinding tools? Now let's take everyone to learn about it together.

1. The hardness of the grinding tool mainly depends on the amount of binder added and the density of the grinding tool. If the abrasive particles are easily detached, it indicates that the hardness of the grinding tool is low; On the contrary, it indicates high hardness. The hardness grades are generally divided into seven levels: ultra soft, soft, medium soft, medium, medium hard, hard, and ultra hard, and several sub levels can be further subdivided from these grades. The commonly used methods for determining the hardness of grinding tools include the hand cone method, mechanical cone method, Rockwell hardness tester method, and sandblasting hardness tester method.

2. The hardness of the grinding tool corresponds to its dynamic elastic modulus, which is beneficial for using the audio method to determine the dynamic elastic modulus of the grinding tool to represent its hardness. In grinding processing, if the material hardness of the workpiece being ground is high, a lower hardness grinding tool is generally selected; On the contrary, choose grinding tools with high hardness.

The factors that affect the hardness of grinding tools have been shared with everyone. Grinding tool products with different hardness are suitable for different industry needs and need to be judged based on specific circumstances. It is not necessarily the higher the hardness, the better. This should be judged based on the actual situation.
