ABSTRACT:
In a coolant supply method and apparatus for a grinding machine, when an end surface of a workpiece is ground with a grinding wheel end surface of a grinding wheel with coolant being supplied toward a grinding point, a first coolant flow is ejected toward a first position which is on the grinding wheel end surface on an upstream side of the grinding point, and intercepts an air layer rotating to follow the grinding wheel end surface. At the same time, a second coolant flow is ejected toward a second position which is on the grinding wheel end surface and which is closer to the grinding point than the first point, and clings onto the grinding wheel end surface at the second position where the follow air layer has been intercepted by the first coolant flow. Thus, the coolant of a sufficient volume can be supplied to the grinding point where the grinding wheel end surface grinds the end surface of the workpiece.
