According to the deburring device 1 of the present invention configured as described above, when a plurality of holes are drilled in the radial direction from the outer peripheral surface of the annular member that is the workpiece W toward the center, the annular member The burr generated in the hole portion on the inner peripheral surface of the inner surface is removed using the deburring device 1 of the present invention. In this case, first, the workpiece W to be deburred is set on the table 2 and fixed. Next, the distance between the tips of the blades 7 of the rotary head 6 is adjusted at intervals facing the diameter of the inner diameter surface of the workpiece W, and the rotary head 6 is inserted into the workpiece W, for example, as shown in FIG. As shown in FIG. 4, the cam portion 34 is first rotated by a spring force of the spring 35 by pushing the cam portion 34, that is, the tip holder 41 radially outward, so that the blade edge of the blade 7 is covered. Since it contacts the inner peripheral surface of the workpiece W, the cutting edge of the blade 7 slides on the inner peripheral surface of the workpiece W by the rotation of the rotary head 6 and deburring is performed.
[0025]
Next, the rotary head 6 is similarly rotated by approximately 190 ° in the opposite direction, that is, in the clockwise direction. At this time, as shown in FIG. 12, the cutting edge of the blade 7 is retracted in the direction away from the inner peripheral surface of the workpiece W by the cam portion 34, so that the back side of the blade 7 hits the burr and the hole of the workpiece W is formed. It is not pushed in, and therefore the pushing action of burrs is avoided. Next, as in the previous case, the rotary head 6 is rotated counterclockwise again as shown in FIG. 11 to perform deburring, and such a horizontal rotation of about 190 ° is repeated several times. Since the deburring can be performed satisfactorily, a smooth and suitable processed surface can be obtained.
