Abstract:

A creative conception is set up to exploit the potentialities of high efficiency grinding to great extent through enhancing heat transfer of the grinding zone, and a new grinding fluid providing device is put forward to enhance heat transfer of the grinding zone by the high pressure jet impingement. Furthermore, theoretical and experimental studies on the effect of the jet impingement are completed. The calculated results well correspond with the tested ones.
