CNC tool grinder is widely used, how to choose the right grinding wheel to get a good grinding effect? The commonly used resin bond grinding wheel and metal bond grinding wheel and hybrid bond grinding wheel are used for cutting tool grooving.
Resin bond grinding wheel has a certain elasticity, can play a role in polishing, the finished tools are better. But the high temperature resistance of the resin is not very high, the temperature exceeds a certain temperature and the shape retention will decline, and the rounded corners are easy to appear.
Metal bond grinding wheel has high strength, high temperature resistance, good shape preservation and high grinding efficiency. But the metal hardness is relatively high, not easy to trim.
Hybrid bond diamond grinding wheel has the elasticity and good finish of resin bond, and has the wear resistance and good shape retention of metal bond, so it is a good choice for cutting tool powerful grooving.
The single side cutting depth of grooving can be up to 6mm and the feed speed can be up to 90-120mm/min. Due to the small grinding resistance and low grinding temperature, there will be no crack, burn and thermal deformation of the bar when the powerful slotting wheel is processed. At the same time, the powerful slotting grinding wheel has little wear and tear when it is used, and the dressing cycle and service life of the grinding wheel will be greatly improved.
Suitable grinding machine:
WALTER, ANCA, Saacke, DECKEL, Schute, ROLLOMATIC, STAR, Taiwan DINFWEI, Cincinnati, Viking, SCHNEEBERGE, Strausak etc.

<< ：The case of processing PCD reamer with vitrified diamond grinding wheel
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.
