In a method and an apparatus for supplying coolant in a grinding machine while the grinding machine (1, 90) grinds, a cooling nozzle (37) and a cleaning nozzle (38) are mounted on a moving member (61), and the moving member (61) is moved in a direction identical with a first normal line (K2), relative to the grinding wheel (8), at a first predetermined angle (&thetas;1) away from a reference straight line (K1) perpendicular to an axis (CL) of a main spindle. The reference straight line (K1) passes through a grinding point (P1). Accordingly, the cooling nozzle (37) injects the coolant (La) with an injecting outlet port (34) directed in a direction of a tangential line (K3), of the grinding wheel (8), passing through the grinding point (P1). The cleaning nozzle (38) injects the coolant (Lb) with an injecting outlet port (36) directed in a direction of a normal line (K4) relative to the grinding wheel (8). <IMAGE> |
