Abstract:
A method for improving the wear resistance of resin diamond grinding wheel is made by powder hot pressing method, which is characterized by the use of diamond and powder filler particles, which are activated by surface treatment. The resin powder includes phenolic resin powder, polyimide resin powder, Dialok939p resin and other heat resistant resin powder. Surface activation treatment is the use of impregnation method to make diamond and powder filler particles surface coated with a layer of heat resistant silicone or organic fluorine coating can improve the bonding properties of diamond and powder filler particles surface and resin, improve the body strength of resin bonded diamond wheel, on the other hand, can improve the heat resistance and wear resistance of resin bonded diamond wheel. The wear resistance of the grinding wheel can be increased by 15% to 10 if the resin is phenolic resin, and the wear resistance of the grinding wheel can be improved by 10% to 5 if the resin is used as a polyimide resin or Dialok939p resin.
