を回転させるようになっているのが一般的であった。[Prior Art] Conventionally, as shown in FIG. 2, a device for rotating a grindstone of a machine tool has a grindstone attached to one end of a grindstone 12 supported by a grindstone shaft support 11 via bearings 2 at both ends. The grinding wheel 7 is fixed to the grinding wheel mount 3 by attaching a pulley 14 to the other end of the mount 3 and driving the pulley 14 with assistance.
It was common for the machine to rotate.

ことを［］的とする。[Problem to be Solved by the Invention 1] However, when the above-mentioned device is used to grind, for example, a small-diameter deep hole, the grindstone shaft needs to be a small-diameter long shaft, and such a grindstone shaft has a high rigidity. Because it is small, it rotates at high speed!
Since harmful vibrations such as resonance or deflection due to load may occur in the samurai, sufficient circumferential speed of the grinding wheel, machining efficiency, machining accuracy, etc. (there was a problem that it would not be nipped). The purpose is to provide a grindstone rotating device that does not cause any problems.

It is characterized by a sharpened whetstone mount.

率の向上にも寄り・する。The injected grinding fluid collides with the blades of the grinding wheel mount, exerting rotational force on the grinding wheel mount, and acts as a coolant during grinding. Since the grinding wheel mount does not have a rotating shaft with a small diameter and a long axis, harmful vibrations such as resonance that occur when the shaft rotates at high speeds do not occur, and it can rotate at a circumferential speed that is suitable for the grinding wheel. The rigidity of the body is large and the shaft does not deflect, so it rotates while maintaining high machining accuracy. Since high-speed, high-precision machining becomes possible, it also helps improve machining efficiency.

In FIG. 1, the grinding wheel support 1 has an inner ring of a rolling bearing 2 fitted to one end 1a, an outer ring of the rolling bearing 2 fitted to the inner surface of a grinding wheel mount 3, and the grinding wheel mount 3 rotates. freely supported. The grindstone mount 3 is provided with annular blades 4 between the inner and outer surfaces thereof, and a fluid injection port 5 is provided on the side surface of the grindstone support 1 facing the blades t. The fluid injection port 5 communicates with a fluid passage 6 provided through the grindstone support 1 . When pressurized grinding fluid is sent into the fluid flow path 6 from a grinding fluid pump (not shown), the grinding fluid injected from the fluid injection port 5 collides with the blades 4 of the grinding wheel mount 3, causing the grinding wheel mount 3 to rotate. A grindstone 7 for grinding is fixed to the outer periphery of the grindstone mount 3, and grinding is performed. The grinding fluid that is injected and exerts a rotational force on the grinding wheel mount 3 is also used as a coolant during grinding.
