[0006] The method of the invention is as follows: the effective grinding is divided into black skin-coarse advancement-fine advancement-light advancement-light delay grinding stage, and fast advance and fast trend are used to eliminate the gap in the idle stroke feed before effective grinding. , By collecting the real-time current signal of the grinding wheel drive motor to judge the contact state of the grinding wheel and the workpiece; according to the parts to be processed, set the fast forward amount and fast trend that constitute the idle stroke, and preset the fast forward speed and fast trend speed. Set the fast trend function test before grinding the first part of the whole batch of model specifications, the test is started by the test button set in the control system, and set the current value of the grinding wheel drive motor during fast forward function test to the no-load current , Set the current value of the grinding wheel drive motor at the end of the fast approac...
