Cylindrical grinding of various diameters, grooves, thrust surfaces and shapes with one unit. Suitable for cylindrical grinding of milling cutters, drills and taps, grooves, flats, threads and chamfers.

Features of step grinding mill
—— High precision and high efficiency
—— Centering and step-difference forming cylindrical grinding
—— One-time rough and fine grinding of punching and needle, high finish
—— Ceramic CBN grinding wheel requires less dressing, while electroplated CBN grinding wheel does not need dressing.
—— Ceramic bond (higher efficiency than resin bond) or electroplated bond for rough grinding
—— Metal bond for fine grinding
