によって固定されている。As shown in FIGS. 3 and 5, the cutting tool 60 has cutting edges 62, which have the same addendum angles on their four sides.
62, 63, 63 are formed. On the other hand, a positioning surface 56 having the same inclination angle as the tip angle of the blade 5 is provided along the axial direction at a position near the rear end of the blade mounting surface 54 of the blade mounting portion 54 in the rotational direction. Has been formed.
The blade 5 has the blade mounting bolt 59 in a state in which one of the pair of first cutting blades 62, 62 extending in the longitudinal direction is abutted against the positioning surface 56.
Is fixed by.

れる。When the blade 5 is fixed to the blade fastening surface 55, the other first cutting edge 62 of the blade 5 is used.
Has a tooth tip protruding forward from the front end 55a of the tool fastening surface 55 by a predetermined amount, and one cutting edge 63 of the pair of second cutting edges 63, 63 has an end on the shaft end side of the tool fastening surface 55. It projects from the edge 55b axially forward by a predetermined amount. That is, in this conventional cutting tool 51, the amount of protrusion of the cutting edge on the peripheral surface side (in other words, the mounting position of the blade 5 in the radial direction of the blade holder) is determined by the first cutting edge 62 of the blade 60 and the blade mounting portion 54. It is achieved by abutting against the positioning surface 56 of the. The protrusion amount of the second cutting blade 63 (in other words, the mounting position of the blade 5 in the axial direction of the blade holder) does not define this, and is set by the empirical subjectivity of the operator.

ことになる。However, when the blade 60 is re-polished, the width dimension (that is, the distance between the pair of first cutting edges 62, 62) and the length dimension (that is, the distance between the pair of second cutting edges 63, 63). It is unavoidable that both dimensions decrease. However,
In the conventional cutting tool 51, as described above, the blade 60
The positioning of the blade holder in the radial direction of the blade holder is performed on the positioning surface 56 formed on the rear end side of the blade tightening surface 55.
Since the cutting blade 62 is made to abut, the re-polished blade 60 is made to abut the positioning surface 56 of the blade mounting portion 54 with one of the first cutting blades 62 as in the case of a new product. And position the blade holder in the radial direction,
Naturally, the amount of protrusion of the tooth tip is smaller than the regular amount of protrusion (that is, the amount of protrusion at the time of new product), and the planned cutting ability cannot be exhibited.

Particularly in the case of automatically controlling the cutting work, there may occur a problem that the initially planned work accuracy cannot be secured due to a change in the distance between the tool shaft center and the tooth tip. Further, if it is attempted to perform the positioning with the regular protrusion amount, it is inevitable that the operator must rely on the intuition of the operator, which causes a new problem such as a decrease in workability or a variation in positioning accuracy.

のが通例であった。Therefore, in general, although there is a demand for re-polishing and reusing the blade 60 from the viewpoint of cost reduction, it is necessary to avoid the inconvenience associated with the re-polishing as described above. When the sharpness of the cutting blade became poor, it was customary to discard it and mount a new blade 60 newly.

It is screwed into the screw holes 7, 7, 7 on the surface 10 side, and these are fastened and fixed by the blade mounting bolts 6, 6, 6. This completes the assembly of the blade 5. Therefore, it becomes possible to perform a predetermined cutting operation using the cutting tool 1 to which the blade 5 is attached. In this case, as described above, the blade 5
Since the cutting edge corner portion 39 of the above is projected forward from the blade holder end surface 2a, it is possible to perform not only the cut edge cutting processing but also the groove cutting processing using the cutting edge corner portion 39 together. .

再研磨が必要となる。Reattachment of the cutting tool 5 after re-polishing When the predetermined cutting process using the cutting tool 1 is performed for a long period of time, the cutting edge portion of the cutting blade 32 is gradually worn away and its sharpness deteriorates. Therefore, in such a case, it is necessary to re-polish the blade 5.

りである。When the blade 5 is re-polished, the width of the blade 5 (that is, the dimension in the direction orthogonal to the longitudinal direction of the cutting edge 32) is reduced by the amount of grinding. Therefore, when the blade 5 is positioned on the rear end side of the blade 5 as in the conventional case, when the width dimension of the blade 5 is shortened by re-polishing, the blade tip extension amount is increased in the rear end side positioning. Since the accuracy cannot be obtained, it is already described that this is discarded and replaced with another new blade 5 without re-polishing.

ものである。However, in the embodiment,
Since the blade 5 is positioned in the radial direction (that is, the amount of protrusion of the blade tip is set) on the front side in the extending direction of the blade 5, the width of the blade 5 becomes smaller than that of a new product by re-polishing. However, without being affected by this, it is possible to mount it in the regular position again like a new product. That is, when the cutting blade 32 portion of the blade 5 is re-polished, the third contact surface 35 serves as a positioning portion of the blade 5 in the minor axis direction.
And the sixth abutment surface 38 by a dimension corresponding to the reduction of the blade width dimension by re-polishing, the second abutment surface 34 and the fifth abutment surface 38.
The abutment surface 37 is cut along the inclination direction. In this way, the re-polished blade 5 is mounted again on the blade fastening surface 10 of the blade holder 2, and the third contact surface 35 and the fifth contact surface 37 correspond to the blade. By abutting the third guide surface 13 and the sixth guide surface 16 on the side of the fastening surface 10, the position of the cutting edge 32 of the cutting edge 32 is reset to the same position as when a new product is mounted. Therefore, when cutting is performed using the re-polished blade 5, the same processing accuracy and workability as when using a new blade 5 can be secured.

である。In this case, since both ends of the blade 5 in the longitudinal direction are guided by the inclined surfaces, the blade 5 is scraped by the third abutting surface 35 and the sixth abutting surface 38, so that the blade 5 is more than a new one. When fixed in a state where it is entirely advanced, it also moves forward in the axial direction at the same time, and the cutting edge corner portion 3 of the cutting tool 5 is also moved.
9 is automatically set to the same protruding position as that of a new product.

に寄与し得るものである。As described above, in the cutting tool 1 according to this embodiment, even if the width dimension of the blade 5 is reduced and changed by the re-polishing, the cutting tool 1 is not affected by the change, and the cutting tool 1 can be easily mounted again at the regular mounting position. Since it can be set with a simple operation and reliably, the blade 5 can be re-polished and repeatedly used, and as a result, the material cost can be reduced, which can contribute to cost reduction.
