Scope: Centerless grinding wheel processing object: carbide rods, nozzle materials, six surfaces Dingding hammer, diamond composite films, magnetic rods and other rods; workpiece material: carbide, PCD, PCBN, magnetic material etc. ; 
 Centerless grinding wheel is mounted on the bed using a centerless grinding mill, which with the guide wheel, pallets interaction, composed of a grinding method, the workpiece to be machined by the pallet lift up by the guide wheel to the pallets direction of circular motion while rotating the workpiece driven by the centerless grinding wheel, workpiece surface quality in grinding high precision is also relatively high, grinding, select the wheel size is also important, coarse-grained grinding wheel is often unintentional used for rough grinding process, means that not only the high processing requirements of the workpiece, generally grinding in order to speed up processing speed, large amount of processing the first processing of the workpiece will adopt this approach, which is due to its processing the characteristics of faster, but the lower parts of the finish. The fine-grained grinding wheel quality precision machining of the workpiece on the contrary, its processing speed slightly slower, but the workpiece to be machined finish, such as the choice of the appropriate size mirror effect can be achieved, therefore, is to select the centerless grinding wheel according to workpiece to choose the specific technical requirements. Including the hardness of grinding wheels, tissue density, size choice.
