2. Description of the Related Art Normally, a blade portion attached to a milling cutter can be efficiently used by repeatedly re-grinding a cutting tip at the blade tip. For example, as disclosed in Japanese Utility Model Laid-Open No. 58-164618, a relatively long blade is used to cope with repeated polishing, and a long wedge member for clamping the blade is used. It is known that after the re-polishing, the rear end of the blade is pressed by an adjusting screw to position the tip of the cutting tip.

However, in the above-mentioned prior art, the pressing surface of the long wedge member is in full contact with the side surface of the long blade, and the blade and the wedge member slide against each other. I can't let you do it. Therefore, when adjusting the position of the blade after re-polishing, it is necessary to completely loosen the set screw for fixing the wedge member to the cutter body,
The whole re-polishing work of the blade becomes complicated. Moreover, when the wedge member is fixed by tightening the set screw after positioning the blade after re-polishing, the wedge member and the blade are easily moved, and the tip of the cutting tip of the blade is efficiently and highly accurately. Problems have been pointed out that are difficult to position.

When the cutting work by the milling cutter 10 is continued, the chip 38 is worn. Therefore, after the worn tip 38 is re-polished, an operation of positioning the tip 38 with respect to the cutter body 12 is performed. At this time, in the present embodiment, the first relief grooves 44a and 44b having a narrow width and the second relief groove 46 having a wide width are formed on the pressing surface 42 of the clamp member 36.
And the pressing surface 42 and the surface 3 of the blade portion 32 are formed.
The sliding contact area with 2a is configured to be considerably narrow. Therefore, by slightly loosening the set screw 54, the blade 32
And the clamp member 36 are slidable with respect to each other, and the blade portion 32 is easily taken out from the mounting groove portion 16. Here, when the set screw 54 is rotated in a direction in which the right screw portion 56 is screwed into the first and second set screw holes 28 and 30 of the cutter body 12, the left screw portion 58 and the first and second reverse screw holes are rotated. The clamp member 36 moves in the radial outward direction of the cutter body 12 via 50 and 52, and the wedge function for the blade portion 32 is released.

Next, when the set screw 54 is rotated in the direction to be separated from the first and second set screw holes 28 and 30 of the cutter body 12, the clamp member 36 is moved to the cutter body 1.
The blade portion 32 is moved inward by a radius of 2 and the blade portion 32 is fixed through its wedge function. In this case, since the set screw 54 is slightly relaxed as described above, the blade portion 32 can be firmly fixed via the clamp member 36 by only slightly rotating the set screw 54. This allows the chip 38
When the setscrew 54 is screwed in after positioning, the clamp member 36 and the blade portion 32 do not move unnecessarily, and the positioning operation of the tip 38 can be performed with high accuracy and efficiency.

2 a is inclined by a predetermined angle θ ° in the rotation direction of the cutter body 12 (direction of arrow C) with respect to the axial direction of the cutter body 12 (direction of arrow A). Therefore, the tip 38 has a rake angle (see FIG. 4), and the cutting operation by the tip 38 is favorably performed. Moreover, the set screw 5
The axial direction of 4 is parallel to the pressing surface 42 of the clamp member 36. Therefore, the blade surface 32 can be uniformly pressed and held by the pressing surface 42 under the screwing action of the set screw 54.

Since a plurality of relief grooves are provided on the pressing surface of the clamp member that comes into contact with the surface of the blade portion, the contact area between the clamp member and the blade portion becomes narrow, and the sliding between the clamp member and the blade portion becomes small. Dynamic resistance decreases. For this reason, the position can be adjusted while the blade is securely fixed, so that the position adjusting work of the blade can be simplified and the blade can be positioned accurately and efficiently.
