General grinding tungsten steel (ie alloy) can use the "green silicon carbide wheel", but also can use the "diamond grinding wheels."
"Green Silicon Carbide Wheel" using green silicon carbide material production, color is green. Because of the characteristics of the material itself, the workpiece can be widely used in hard and brittle materials, but generally not suitable for processing large material toughness. Because of its sharp abrasive, high hardness, it is possible to grind cemented carbide, optical glass, ceramics, alloys.
diamond wheels," which is based on diamond abrasive raw materials, respectively, with metal powder, resin powder, ceramic and metal plating as binder, made of abrasive. Because diamond abrasive with the characteristics (high hardness, high compressive strength, wear resistance), so diamond abrasive grinding process in the grinding hard and brittle materials and carbide is the ideal tool.
