ンドルの故障につなかったりするという問題があった。Problems to be Solved by the Invention However, with the above configuration, the grinding powder generated when the workpiece is ground rises up in the form of a mist, enters the hollow part of the spin I shaft, and is exposed to the inner wall of the hollow part. It hardens and sticks. Eventually, the hollow part may become clogged with grinding powder. If grinding fluid is flowed with grinding powder solidified and stuck to the inner wall of the hollow part of the spindle shaft, the grinding fluid will flow backwards along the inner wall of the hollow part, and may be applied to the motor and cause electrical leakage, or may enter the spindle bearing and cause damage to the spindle. There was a problem that it could lead to malfunction.
