DEFINITION OF TERMS OF HIGH-PERFORMANCE LOW TEMPERATURE GRINDING

Abstract

It has been analytically established that when grinding, it is possible to realize the condition of stabilization of the cutting temperature, which provides at the same time an increase in processing productivity, using the progressive method of deep grinding with a relatively low speed of the part and grinding depth of more than 5 mm In this case, with an increase in the grinding depth or the speed of the part (within certain limits), the cutting temperature remains constant, and the processing productivity increases. This is confirmed by the results of experimental studies. On this basis, the conditions for reducing the cutting temperature while substantially increasing the processing productivity are substantiated and practical recommendations are given for choosing rational grinding parameters according to the temperature criterion. It is shown that under blade conditions, under certain conditions, it is possible to increase the processing productivity over a wide range without actually increasing the cutting temperature, which is consistent with experimental data. This is due to a decrease in the fraction of heat leaving in the surface layer of the workpiece.
