In this case, the gap between the peripheral surface of this hole and the outer peripheral surface of the grindstone shaft above the grindstone is such that the grinding part side becomes narrower and the axial direction of the deep hole and the supply nozzle is inclined, and further above the workpiece. Since the tip of the supply nozzle is located, there is a problem that the grinding liquid cannot be sufficiently supplied to the grinding portion. It should be noted that it is impossible to reduce the inclination angle of the supply nozzle to approach the vertical direction because the supply nozzle interferes with the outer circumference of the rotating tool holder.

Can be supplied with grinding fluid. Then, even if the hole is deep, the tip of the supply nozzle is inserted into the hole when the spindle descends together with the spindle head, so that the grinding liquid is removed from the position approaching the grinding portion without any trouble from the tip. Can be supplied. Since the supply nozzle has a semicircular cross section including the tip, a large amount of grinding fluid can be supplied.
