Abstract:
A method for supplying coolant in a grinding machine, while said grinding machine grinds, which grinds a workpiece by rotating a grinding wheel mounted on a main spindle and by relatively moving the workpiece and the grinding wheel along at least three mutually transverse axes including a direction parallel with an axis of the main spindle, said method comprising the following steps of:mounting on a moving member at least one first nozzle, for cooling a grinding point at which the grinding wheel grinds the workpiece, and at least one second nozzle for cleaning a periphery of the grinding wheel; and moving said moving member in a direction substantially identical with a first normal line, relative to the grinding wheel, which is positioned at a first predetermined angle away from a reference straight line passing through the grinding point and being perpendicular to the axis of the main spindle, whereby said first nozzle injects said coolant with an injecting outlet port directed in a direction substantially identical with a tangential line, of the grinding wheel, passing through the grinding point, and said second nozzle injects said coolant with an injecting outlet port directed toward a point on the surface of the grinding wheel and in a direction withinÂ±30 degrees of the radial line from the axis of the grinding wheel through said point on the surface of the grinding wheel.
