Tóm tắt

This paper describes the grain damage characteristics of a grinding wheel with laser-brazing and discusses its relationship to the normal grinding force during the face grinding of granite. The results of our experiment show that the primary wears patterns of the brazed diamond grinding wheel in the whole grinding process are whole, wear-away, micro-fractured, and macro-fractured. There is no type of falling-off for the diamond grinding wheel, so the result indicates that it is possible to braze the diamond grits through appropriately manipulating the parameters of the laser. During the grinding process, the diamond shapes cause grinding forces to vary, and these variations actuate the transformation of the diamond shapes. The results obtained in this paper provide a reference for researching the wear mechanism of diamond grains, for optimizing grinding parameters, and for consummating the manufacture of laser brazed diamond tools.
