The surface hardness is increased by abrasive belt machine
Abrasive belt machine is in the process of preparation of metallographic specimen for metallographic metallographic specimen, important equipment to throw light on the. It takes must size of abrasive belt, and active grinding techniques, machine sustainable and stable operation without need oneself for interference, can pass the power step motor with imitation rangefinder precise control to ensure accurate grinding depth. Through belt machine polished specimen, the metallographic sample can be made bright as mirror surface, modified surface layer microstructure of, robot which belongs to a cement machine, progress nominal hardness constitute wear-resistant, anti fatigue caused by thin metal layer.
