Description of the Related Art Generally, a finishing cutter has a front cutting edge having a wide cutting width on an end face of an outer peripheral portion of a tool body, and performs a finishing cutting by using the same cutting edge. In particular, a throw-away type cutter (hereinafter, abbreviated as a cutter) using a throw-away tip (hereinafter, abbreviated as a tip) as a cutting blade does not require re-grinding, and the tool body is semi-permanently permanent. It can be used and is widely used because the tool cost is reduced.

なっている。Conventionally, among the cutters of this type, in particular, a cartridge which is provided with a cutting blade in an axially position-adjustable cartridge to facilitate the position adjustment of the cutting blade is disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 6 (1994).
No. 0-186311 is disclosed.
Examples of these conventional cutters are shown in FIGS. In this cutter, a tip pocket 2 is formed on the outer periphery of an annular tool body 1 that is rotated about an axis, and a part thereof is removed toward the outer periphery.
A concave portion 3 is formed at the rear side in the cutting rotation direction. A cartridge 4 is mounted in the recess 3 with a tightening screw 5 with its side surface abutting against the bottom surface of the recess 3. A tip 7 having a cutting blade 6 is detachably mounted with a screw 8 or the like. On the other hand, a wedge 9 is attached to the base end of the cartridge 4 in the axial direction by a clamp screw 10, and the rotation of the clamp screw 10 causes the tool body 1 to rotate.
, The position of the cartridge 4 can be adjusted along the axial direction.

与え、振れ調整がしにくいという問題があった。Generally, in the cutter, after the replacement of the insert 7, it is necessary to adjust the position of the cutting edge, that is, to adjust the run-out, in order to improve the finished surface roughness of the work material. . In such a case, in the conventional cutter described above, the adjustment is performed by rotating the clamp screw 10 to push the wedge 9 into the concave portion 3 and pushing the cartridge 4 in the axial direction of the tool body 1. However, the amount of change in the axial width of the wedge 9 pushed into the recess 3 by the rotation of the clamp screw 10 and, as a result, the amount of movement of the axial width of the cartridge 10 pushed in the same direction are different. Since they are equal, there is a problem that a slight difference in rotation of the clamp screw 10 causes a large change in the pushing width of the cartridge 4, and it is difficult to adjust the runout.

In addition, on the arc centered on the axis of the tool main body front end face 1a, the tool main body front end face 1a extends along a tangential direction to the arc.
Is provided in the base direction.
Here, the bottom surface of the concave portion 3 is an inclined surface that gradually projects toward the distal end side in the axial direction of the tool main body as the longitudinal direction goes from the rear end to the front end of the concave portion 3 along the rotation direction of the tool main body 1 (arrow X in FIG. 1). 11 and are formed at the same height in a direction orthogonal to the longitudinal direction. At the tip of the recess 3 in the rotation direction, there is provided a tip pocket 2 formed by cutting out the tool body tip surface 1a.

The inclined surface 11 is formed by the tightening screw 5 inserted into the elongated hole 12.
The mounting recess 13 is formed at the tip of the tool body tip surface 1a side. Then, in the mounting recess 13, the chip 7 having a substantially flat plate shape is provided.
The ridge is detachably mounted with a screw 8 with the ridge protruding from the tool body tip surface 1a, and a front cutting edge 6 is formed on the ridge. The front cutting edge 6 is parallel or convex to the tool body boss surface 1b as shown in FIG.

１a方向に突出し、カッターの高さが高くなる。The run-out adjustment in the cutter of the present invention is performed by rotating the clamp screw 10 and changing the amount of pushing of the wedge 9 into the concave portion 3 so that the cutting depth of the front cutting edge 6 is an optimum value for cutting. Is performed by pushing the cartridge 4 out. In particular, the amount of movement of the cartridge 4 pushed out in the same direction in the same direction as a result is smaller than the amount of change in the width in the axial direction of the wedge 9 pushed into the recess 3 by the rotation of the clamp screw 10. Therefore, clamp screw 1
Fine adjustment of the pushing amount of the cartridge 4 is possible by the rotation of 0. In this case, when the clamp screw 10 is rotated in the direction in which the wedge 9 is pushed in, the cartridge 4 moves rightward in FIG. 3, so that the front cutting edge 6 protrudes in the direction of the tool body front end surface 1a, and the height of the cutter is reduced. Get higher.

May be appropriately determined according to the tool diameter and the like, but is preferably 5 ° to 30 °. If the angle is less than 5 °, the amount of movement of the cartridge 10 in the axial direction with respect to the amount of change in the axial width of the wedge 9 pushed into the concave portion 3 during the run-out adjustment is extremely small, and the run-out adjustment is performed. On the other hand, if the angle exceeds 30 °, the amount of movement of the width of the cartridge 10 in the axial direction with respect to the amount of change in the width of the wedge 9 pushed into the concave portion 3 during the run-out adjustment may be reduced. This is because there is a possibility that the size becomes large and fine adjustment of the shake becomes difficult. In the present embodiment, the clearance angle α of the front flank connected to the front cutting blade 6 is the same as the inclination angle θ, and the angle β formed by the wedge 9 is 10
°.

きさである必要がある。FIG. 4 shows a second embodiment of the present invention. In the present embodiment, the inclined surface 11 protrudes in the direction opposite to the rotation of the tool body 1 in the direction of the tool body tip surface 1a. Therefore, when the clamp screw 10 is rotated in the direction in which the wedge 9 is pushed in, the cartridge 4 moves rightward in FIG. 4, so that the front cutting edge 6 retreats toward the base end of the tool body, and the height of the cutter decreases. Become. in this case,
In order for the clearance angle α of the front flank to have a predetermined angle, the angle γ formed by the inclined surface 11 and the front flank must be larger than the inclination angle θ of the inclined surface 11 with respect to the tool body tip surface 1a.
There is a need to be of wood.

付剛性が高く、従って切削時の安定性も高い。In the cutter of the present invention, since the concave portion 3 is opened only on the tip end surface 1a of the tool main body, the rigidity of the tool main body 1 due to the opening of the concave portion 3 is less reduced than the conventional cutter. Further, since the cutting load is received by the entire inclined surface 11 having a relatively large area, the mounting rigidity is higher than that of the conventional cutter, and therefore, the stability at the time of cutting is also high.
