Abstract: Two basic countermeasures are advanced to solve the difficult problem and further develop the potentiality of high efficiency grinding. One is to study and make brazed super-hard abrasive grinding wheel to increase the sharpness of the grinding wheel for decreasing the specific grinding energy so as to reducing grinding heat as fully as possible. The other is the intensified cooling technology of diamentral jet impingement in the grinding zone to steadily control the temperature of workpiece surface at extremely low lever under the heat flux far exceeds the critical value. They will be widely used to solve the problems of grinding burn of difficult-to-machining materials.
