使用、シムによる調整も行なわれている。 In general, a side cutter for cutting a bevel used for welding bevel processing of steel plates, etc., as shown in FIG.
It is composed of a large number of throw-away chips (hereinafter referred to as chips) 4a to 4c held at equal intervals on the circumference of part b via supports 3a to 3c, and as shown in FIG. The groove 6 of 5 is being processed. However, if the thickness of the workpiece 5 is different, machining cannot be performed with the same chips 4a to 4c held, so the cutters 2a and 2b are removed from the cutter mounting shaft 1 each time, and the mounting width of the chips 4a to 4c is The reality is that this has been addressed by changing the . Figure 1a shows the case where the workpiece 5a is a thick plate, and Figure 1b shows the case where the workpiece 5b is a thin plate.
The installation width of a to 4c must be changed so that W>w, and the method of changing this is to use the split type cutter shown in Fig. 1a and adjust the installation width with the liner 7 according to the plate thickness, etc. Special supports for each plate thickness are used and adjustments are made using shims.

る。 FIG. 4a shows a case where a thin plate-shaped workpiece 15a is grooved.
Attach the outer diameter thread 1 of the ring 18 to the inner diameter thread 12a' of a.
8' and the lower surface of the cutter 12a and the ring 1.
Rotate and screw the ring 18 until the bottom surfaces of the rings 8 and 8 are aligned. Next, the protrusion 12 of the cutter 12b
The sliding portion 18'' of the ring 18 that is integrated with the cutter 12a is fitted into b', and the cutters 12a and 12b are opposed and overlapped as shown, and the bolt 20 with a hole is
The side cutters are tightened together and attached to the mounting shaft 11 of the milling machine as an integrated side cutter.

の移動量が形成される。 On the other hand, when beveling a thick plate-shaped work material 15b, as shown in FIG. 4b, the ring 18
This is done by rotating the cutters 12a and 12b to create a gap 17 between them. That is, the gap 17 is set depending on the thickness of the workpiece 15b to be machined. First, when the hole bolt 20 is loosened and the ring 18 is rotated in the direction in which it is screwed in, the cutter 12b
The protrusion 12b' and the ring sliding contact part 18'' slide,
As the inner diameter thread 12a' of the cutter 12a and the outer diameter thread 18' of the ring 18 are screwed together, the sliding contact portion 19a' drilled in the cutter 12a and the bolt with a hole are loosened from the threaded hole 19b of the cutter 12b. The cutter 12a is pushed upward while the sliding contact portion 20' of the cutter 20 is slid, and a gap 17 is formed. At this time, since the cutter 12a is fixed to the cutter 12b by the plurality of loosened hole bolts 20, the cutter 12a does not follow the rotation of the ring 18. Therefore, if the ring 18 is rotated by an angle appropriate to the thickness of the workpiece 15b, the required cutter 12a
The amount of movement is formed.
なお、リング１８の回転角度は、計算式
カツタ１２ａの移動量（17）＝（リング１８の回転角
度）×（ねじピツチ）×１／360
で算出される。したがつて、たとえば、ねじピツ
チ10mmの場合にリング１８を90゜回転させれば2.5
mm、180゜回転させれば５mmのカツタ１２ａの移動
量が得られることになる。 The rotation angle of the ring 18 is calculated by the following formula: Movement amount of the cutter 12a (17) = (rotation angle of the ring 18) x (screw pitch) x 1/360. Therefore, for example, if the thread pitch is 10 mm and the ring 18 is rotated 90 degrees, it will be 2.5 mm.
If the cutter 12a is rotated by 180 degrees, the amount of movement of the cutter 12a will be 5 mm.
また、リング１８の回転手段としては、レン

For example, a plurality of holes are drilled at equal intervals on the surface of the ring 18, and two claws or pins of a wrench are inserted into two of the holes and turned.

図することができる。 As described above based on the embodiment shown in the drawings, according to the cutter for a milling machine according to the present invention, the amount of movement of the cutter can be easily obtained by simply rotating the ring without removing the cutter. This makes it possible to perform dimensional adjustment with high precision, and also to reduce the time required to replace supports and the like as in the conventional case. Furthermore, there is no need to prepare in advance spare parts such as special supports, liners, shims, etc. for different plate thicknesses, and it is possible to reduce costs.
