A CNC grinding machine is a precision performance tool that uses a rotating wheel to cut material away from metal. Usually, CNC grinding machines are used during the finishing process to create a high-quality metal workpiece for camshafts, ball bearing, transmission shafts, and other working pieces that require precision and perfect finishes.

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
