Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
