The basic principle of grinding in the machining of precision mechanical parts is to remove material from the workpiece by means of an abrasive grinding wheel. The grinding wheel is made up of abrasive particles that are bonded together with a matrix of metal, resin, or ceramic.
During the grinding process, the workpiece is held in a fixture or on a spindle, and the grinding wheel is rotated at high speed. The wheel is then brought into contact with the workpiece, and the abrasive particles on the surface of the wheel grind away the material to produce the desired shape and surface finish.
Grinding is used in the machining of precision mechanical parts because it is capable of producing very accurate and precise shapes and sizes, as well as achieving excellent surface finishes. It is also used to remove material from hard materials such as ceramics and hardened steel, which cannot be machined by conventional cutting processes.
