Abstract:
1. A method of supplying coolant in a grinding machine wherein a grinding wheel carried on a wheel head and rotationally driven is given a grinding feed relative to a workpiece supported on a workpiece support device for grinding the workpiece with a grinding surface of the grinding wheel with coolant being supplied to a grinding point, the method comprising the steps of: providing at a position upstream of the grinding point in a grinding wheel rotational direction a fluid jet nozzle which blows a fluid jet to traverse the grinding surface of the grinding wheel from one lateral side of the grinding wheel to the other lateral side for intercepting a wheel-following air layer rotating to follow the grinding wheel; supplying a large quantity of the coolant while stopping the supply of the fluid jet during a heavy grinding having a large infeed per abrasive grain of the grinding wheel; and supplying a small quantity of the coolant while supplying the fluid jet during a light grinding having a small infeed per abrasive grain of the grinding wheel.
