なっている。Among conventional cutters of this type, a cartridge whose position can be adjusted in the axial direction is provided with a cutting blade to facilitate the position adjustment of the cutting blade.
What is found in 0-186311 is disclosed.
Examples of these conventional cutters are shown in FIGS. In this cutter, a tip pocket 2 formed by removing a part of the tool pocket 1 toward the outer periphery is formed on the outer periphery of an annular tool body 1 rotated about an axis.
A concave portion 3 is formed at the rear of the cutting rotation direction. Further, a cartridge 4 is mounted in the recess 3 with a side surface of the cartridge 4 in contact with the bottom surface of the recess 3 with a tightening screw 5. Further, the front end of the cartridge 4 is substantially parallel to the surface of the work material. A chip 7 having a cutting edge 6 is detachably attached by a screw 8 or the like. On the other hand, a wedge 9 is attached to the axially proximal end portion of the cartridge 4 by a clamp screw 10, and the tool body 1 is rotated by rotating the clamp screw 10.
It is possible to adjust the position of the cartridge 4 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 tip 7, it is necessary to adjust the position of the cutting edge, that is, the so-called runout adjustment in order to improve the finished surface roughness of the work material. . In such a case, in the above-mentioned conventional cutter, adjustment is performed by rotating the clamp screw 10 to push the wedge 9 into the recess 3 and pushing out 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 the amount of movement of the axial width of the cartridge 10 pushed out in the same direction as a result are Since they are the same, there is a problem that a slight difference in the rotation of the clamp screw 10 causes a large change in the pushing width of the cartridge 4, making it difficult to adjust the shake.

行うことが可能である。According to the present invention, the cartridge moves in the longitudinal direction of the inclined surface in accordance with the amount of change in the width of the wedge pushed in, and in the axial direction of the tool body in accordance with the inclination of the inclined surface. Therefore, if the inclination of the inclined surface is made sufficiently small, the movement distance in the axial direction of the cartridge with respect to the movement of the cartridge in the longitudinal direction becomes small, and the change in the shake amount of the chip can be reduced. Therefore, it is possible to easily and accurately adjust the deflection of the chip.

The ridge is projected detachably from the tool body front end surface 1a and is detachably mounted by a screw 8. Further, 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。To adjust the runout in the cutter of the present invention, the clamping depth of the front cutting edge 6 is set to an optimum value for cutting by rotating the clamp screw 10 to change the pushing amount of the wedge 9 into the concave portion 3. The cartridge 4 is pushed out so that In particular, the amount of movement of the width of the cartridge 4 pushed in the same direction in the same direction is smaller than the amount of change of the width of the wedge 9 pushed into the recess 3 by the rotation of the clamp screw 10 in the axial direction. For clamp screw 1
A rotation amount of 0 enables fine adjustment of the pushing amount of the cartridge 4. In this case, when the clamp screw 10 is rotated in the direction in which the wedge 9 is pushed, the cartridge 4 moves to the right in FIG. 3, and as a result, the front cutting edge 6 projects in the tool body front end surface 1a direction, and the height of the cutter increases.

The inclination angle θ with respect to 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 width of the cartridge 10 in the axial direction with respect to the amount of change of the width of the wedge 9 pushed into the recess 3 in the axial direction becomes extremely small during the shake adjustment, so that the shake adjustment can be 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 relative to the amount of change in the axial width of the wedge 9 pushed into the recess 3 during the shake adjustment becomes large. This is because there is a risk that it becomes large and it becomes difficult to finely adjust the shake. In the present embodiment, the clearance angle α of the front flank that is continuous with the front cutting edge 6 is the same as the inclination angle θ, and the angle β formed by the wedge 9 is 10 °.

必要がある。On the other hand, FIG. 4 shows a second embodiment of the present invention. In the present embodiment, the inclined surface 11 projects in the direction of the tool body tip surface 1a along the direction opposite to the rotation of the tool body 1. Therefore, when the clamp screw 10 is rotated in the direction in which the wedge 9 is pushed, the cartridge 4 moves to the right in FIG. 4, and as a result, the front cutting edge 6 retracts in the tool body proximal end direction, and the height of the cutter is lowered. 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 clearance surface must be equal to or greater than the inclination angle θ of the inclined surface 11 with respect to the tool body tip surface 1a. is there.

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 thus the stability during cutting is also high.

Since the inclination of the inclined surface is made sufficiently small, the movement distance of the cartridge in the axial direction of the tool main body with respect to the movement of the cartridge in the longitudinal direction is reduced, and the change of the deflection amount of the tip is reduced.
