Through the cylindrical grinding process, and by using a cylindrical grinding machine, the external or internal cylindrical surface of a work piece are ground. In external cylindrical grinding machine, the work piece rotates and reciprocates along its axis, although for large and long work parts the grinding wheel reciprocates.
