Abstract. This paper describes the technological basis and the current state of the art in the field of high speed grinding. The technological fundamentals of high speed grinding are first of all presented on the basis of the kinematics of the chip-forming process. The paper then goes on to consider energy aspects.
Principle of high-speed grinding: After the grinding wheel speed is increased, the number of abrasive grains passing through the grinding zone per unit time increases. If the feed rate remains the same as in normal grinding. Then the cutting thickness of each abrasive grain becomes thinner during high-speed grinding. At the same time, the load ...
