Description

technical field

[0001] The invention relates to an on-line electrolytic metal bond superabrasive grinding wheel, belonging to the technical field of mechanical precision processing, which can realize online electrolytic sharpening and on-line electrolytic metal bond superabrasive grinding wheel precision mirror grinding. Background technique

[0002] In precision machining, resin bonded grinding wheels (diamond or cubic boron nitride fine grain size) are usually used. It is characterized by certain elasticity and high strength, and good impact resistance. However, its heat resistance and alkali resistance are poor, and the high temperature in the grinding area can burn the bonding agent. The alkaline grinding fluid will reduce the strength and hardness of the grinding wheel, increase the wear of the grinding wheel, and make it difficult to maintain the shape accuracy of the grinding wheel. Since the dressing of the resin bonded grinding wheel can only be done by the diamond...
