Accurate grinding method for coupling half working faces

The invention discloses an accurate grinding method for coupling half working faces and belongs to the field of machining. The problem that under the situation that a machine tool does not have an online detection function at present, it is difficult to control the size and form and location tolerance when the coupling half working faces are ground is solved. Firstly, coarse grinding is conducted, and working allowance is left for accurate grinding; then, the actual accurate grinding allowance is detected in a three-coordinate manner; finally, accurate grinding is conducted, and an outside micrometer is used for auxiliary detection and controlling for the actual removing amount, machine tool machining, a three-coordinate measuring instrument and outside micrometer detection are organically combined, meanwhile, a symmetrical grinding manner is adopted, and the coupling half working faces are accurately ground. The accurate grinding method is used for grinding the coupling half working faces. 种半联轴器工作面精准磨削方法，属于机
