In repairing and newly fabricating a roll or a cylinder (such as hydraulic cylinder, roll for iron making, roll for paper manufacturing, film roll etc.), a process of vertically polishing iron, stainless steel or chrome materials is essential. We can satisfy customer requirements with one of the best products we manufacture, the high-speed roll grinding wheel.
