Grinding is one of the most important manufacturing process for high precision parts. Grinding characterized by low material removal rate and high surface finish is an abrasive machining process. Geometrically undefined grits of grinding wheel influences part surface finish. Cutting edges worn out during grinding are retained by timely dressing.
Since grinding is usually considered as the last procedure for work-piece machining, grinding machines commonly have higher positioning accuracy compared with other machine tools. The grinding wheel spindle is the main part of the grinding machine. Its function is to fix the grinding wheel and drive its rotation in the grinding process.
