Abstract

The invention provides a laser and mechanical composition finishing resin binder diamond grinding wheel method, comprising: adopting high power density pulse laser, focusing a laser beam by focusing lens and irradiating vertically to the grinding surface of the grinding wheel, rotating a grinding wheel, measuring the fluctuation of the grinding wheel round, adjusting the focus position of the laser to lead the focus to be dropped at the maximum position of the fluctuation of the round, adjusting the parameter of the laser in order to lead the maximum position of the fluctuation of the grinding wheel round to reach the value, axially and repeatedly feeding and rotating the grinding wheel till diamond grinding grain part close to the maximum position of the fluctuation round is wholly removed or partly and slightly removed or partly lost with holding force owning to the removal of the bonder through a plurality of finishing, shaping the grinding wheel by using a single-crystal diamond pen or a carborundum idler wheel with definite tip, removing the grinding grain which loses the holding force and the grinding grain metamorphosing layer burned by laser, and repeatedly carrying out the composition processes till required round fluctuation and topography and geomorphology are reached. The invention obviously improves the finishing efficiency of the grinding wheel and leads the cutting surface of the grinding wheel to obtain excellent topography and geomorphology.

Description

technical field

[0001] The invention relates to a dressing method for a resin bonded diamond grinding wheel, and further refers to a method for realizing precise shaping and sharpening of a resin bonded diamond grinding wheel by using laser and mechanical compound dressing. Background technique

[0002] Resin bonded diamond grinding wheel has exceptionally good grinding performance, and has broad application prospects in grinding of difficult-to-machine materials, precision ultra-precision grinding, profile grinding, high-efficiency grinding and grinding automation. In recent years, due to breakthroughs in related technologies such as grinding wheel manufacturing and CNC precision grinding machines, the application of such grinding wheels has increased dramatically. Due to the characteristics of this grinding wheel itself, it is very difficult to dress, and the dressing accuracy is difficult to guarantee, which greatly affects the grinding efficiency, precision, and quality,...
