<p>A grinding apparatus (100) is provided with a rotating grinding tool (102) for grinding a subject (101) which is to be processed and is immersed in a cooling liquid (106); vibration generating mechanisms (107a-107f) for generating cavitation by applying vibration to the cooling liquid (106); and a controller (108) for making the vibration generating mechanisms (107a-107f) generate cavitation when the rotating grinding tool (102) is used. The controller (108) controls turning on/off of the vibration generating mechanisms (107a-107f) and adjusts magnitude of amplitude corresponding to a processing region and processing stage.</p>
