HD5 step grinder

The newly designed HD5 step differential grinding machine equipment adopts the latest industrial numerical control system, integrating high-precision work heads, high-speed motorized spindles, dual-sandwheel synchronous high-speed grinding technologies, etc. It is widely applied in the pre-processing of milling cutters, drills, reamers and various high-precision cutting tools.

The grinding process using coarse and fine double abrasive wheels ensures product accuracy.; 

The self-developed simulation processing software can achieve rapidity, flexibility and customization.
