The present invention aims to make it possible to continuously grind and to prevent the occurrence of a lot of consumables by grinding. The grinding machine (1) of the present invention comprises: an ultrasonic cleaning nozzle (5) which comprises: a spray nozzle main frame (52) for spraying a cleaning solution (51) to a grinding wheel (41); a cleaning solution supply unit (53) for supplying the cleaning solution to the spray nozzle main frame; an ultrasonic vibrator (55) for giving ultrasonic wave to the cleaning solution supplied by the cleaning solution supply unit; and, a power supply means (56) for applying an AC power to the ultrasonic vibrator. The ultrasonic cleaning nozzle is placed to spray the cleaning solution with ultrasonic wave toward a grinding surface (42a) of a grinding stone (42) which grinds an object to be processed (W). The vibration frequency of the ultrasonic vibrators is set to be 450 kHz to 1.0 MHz. |
