Precision grinding technology of diamond abrasive tools based on grinding method

In this experiment, the technology of grinding diamond abrasive tool with complex profile by grinding method is studied. The typical complex diamond tools are grinded by the method of combination of shape and surface with the optical image grinder. The grinding mechanism is analyzed by theoretical analysis, experiment and microscopic observation of the grinding surface. The influence of the basic grinding process on the grinding efficiency and precision is studied and the relevant laws are determined. The results show that the mechanism of grinding removal is that the surface of diamond is slightly broken by the high stress produced by the local contact points in the contact surface of abrasive particles, so the precision grinding technology based on grinding method has the advantages of high efficiency and precision; the main influence factors of the dressing effect are the grinding depth, grinding speed, grinding wheel, etc.; the precision of single element profile grinding can be improved In order to achieve 0.002 5 mm, angle within 5′, the overall profile accuracy can reach within 0.005 mm, and the surface roughness of grinding workpiece by cut in grinding feed mode after dressing can be less than 0.120 μm.
