The hardness and softness of diamond abrasive particles affect the hardness of the grinding wheel. We should pay attention to the appropriate hardness. If it too hard, the dull abrasive can’t fall in time and a lot of heat will burn the work piece, If the grinding wheel is too soft, the abrasive will fall too fast and grinding lift time so short.
Then, how to choose the hardness of diamond grinding wheel
1. The harder the work piece, using the softer the diamond grinding wheel.
2. The larger the contact surface between the diamond grinding wheel and the work piece, choose the softer hardness.
3. For precision grinding and profile grinding, should choose hard wheel.
4. The larger the particle size should choose softness wheel to prevent the grinding wheel from being blocked by grinding chips.
5. When grinding soft materials such as non-ferrous metals, rubber, resin, etc., should choose softness.
