9 or on the elastic sheet 35 on the jig pace 34, and while positioning it with the reference pin 33 and rotating the counterbore cutter 5 via the spindle 3,
When the spindle holder 6 is lowered, the cutter 5 cuts the workpiece W to a predetermined depth, and the workpiece pressing ring 24 presses the upper surface of the workpiece W, as shown in FIGS. 2 and 3. In this case, the workpiece W will descend to some extent due to the elasticity of the support jig, but as shown in FIG. 4, the distance a between the tip of the spot facing cutter 5 and the lower surface of the workpiece pressing ring 24 is constant The depth of the counterbore portion is always a constant depth from the top surface of the workpiece W.
すなわち本発明によれば、ワークＷの上面を基準にして

て元の中心位置に戻される。Further, lateral movement of the cutter 5 during counterboring is absorbed by the play between the cutter 5 and the inner peripheral surface of the workpiece pressing ring 24 . That is, after the workpiece pressing ring 24 comes into pressure contact with the -H workpiece W, it does not move relative to the workpiece W, but the sliding ring 21, which is integrally connected to the workpiece pressing ring 24, moves through the steel ball 23 to the adjustment ring 18. lower surface 18d of
Since the cutter 5 slides against the cutter 5, the lateral movement of the cutter 5 can be absorbed by this sliding movement. When the counterbore process is completed and the workpiece pressing ring 24 is separated from the workpiece W together with the cutter 5, the sliding ring 21 is returned to its original center position by the action of the coil spug 27.

。Further, as described above, the counterbore depth by the cutter 5 is determined by the protrusion length a of the cutter 5 downward from the lower surface of the workpiece pressing ring 24, but in the device of the present invention, the adjustment ring 18 is pressed by loosening the bolt 19. Food 1
4, the protrusion length a of the cutter 5 can be accurately set to an arbitrary value by the action of the screw of the threaded portion of the cutter 5. Moreover, its operation is easy. Once this setting is completed, the threaded portion may be fixed via the shim 20 by tightening the bolt 19.
