Claims

[Scope of utility model registration request]

a workpiece support means for supporting a workpiece; a rotational drive means for rotationally driving the workpiece; a rotary grindstone that rotates in the opposite direction to the workpiece and cuts the workpiece with its own outer circumferential grinding surface; a main high-pressure nozzle that is positioned below the grinding point and projects the grinding fluid at high pressure toward the grinding point; and a main high-pressure nozzle that is positioned above the grinding point and projects the grinding fluid at high pressure toward the grinding point. A grinding fluid nozzle that projects the grinding fluid under high pressure is positioned with the nozzle hole facing downward in the vicinity of the part of the rotating grinding wheel that is approximately opposite to the grinding point, and the grinding fluid nozzle projects its own projection grinding onto the above-mentioned part of the rotating grinding wheel. A grinding machine device characterized by being provided with an auxiliary high-pressure nozzle that projects the grinding liquid at high pressure so that the angle C formed by the liquid and the grinding surface of the rotary grindstone is an acute angle.
