PROBLEM TO BE SOLVED: To provide a grinding device which allows continuous grinding and prevents generation of a large amount of consumable supplies due to grinding.SOLUTION: A grinding device (1) comprises an ultrasonic cleaning nozzle (5) consisting of an injection nozzle body (52) for injecting cleaning liquid (51) to a grinding wheel (41), a cleaning liquid supply part (53) for supplying the cleaning liquid to the injection nozzle body, an ultrasonic vibrator (55) for giving an ultrasonic wave to the cleaning liquid supplied from the cleaning liquid supply part, and power supply means (56) for applying AC power to the ultrasonic vibrator. The ultrasonic cleaning nozzle is arranged so as to inject the cleaning liquid to which the ultrasonic wave is given toward a grinding surface (42a) of a grinding stone (42) grinding a work-piece (W). The vibration frequency of the ultrasonic vibrator is set to be within a range between 450 kHz and 1.0 MHz. |
