Factors to consider when selecting the abrasive hardness

1. Hard abrasive tools are used when processing soft materials, and soft abrasive tools are used instead, but soft abrasives are also used when grinding soft materials and tough materials.

2. When grinding, the contact area between the workpiece and the grinding tool is large, and the hardness of the grinding wheel should be selected lower. For forming grinding, in order to ensure the geometric accuracy of the workpiece, the hardness can be appropriately selected.

Third, during the grinding process, the grinding tool has a high rotation speed, the hardness should be selected lower, the workpiece rotation speed is high, the hardness should be appropriately higher, and the dry grinding hardness should be 1-2 softer than the wet grinding hardness.

  *Binding agent* 

→ The binder mainly fixes the abrasive grains together to have a certain shape and strength, so as to effectively perform the grinding work. There are three commonly used binders, ceramics, resins and rubber.

→The abrasive made of resin binder has high strength and elasticity. It is widely used in metal and non-metal materials, high speed grinding, rough grinding, profile grinding, super fine grinding, cutting and slotting. .
