This cutter unit 0→ consists of a bearing sleeve 01lS that supports the spindle /I10→, a motor M3 that drives the spindle tvab, and a transmission member (not shown) that transmits the output of the motor M3 to the spindle /I/a. Then, cutter 07 attached to the bottom of the tip of Spind /I/(li'9)
) is rotated in a fixed direction.

As shown in FIG. 1, the spindle 101 is rotatably supported with its tip tilted downward, and therefore the cutter 071 is tilted in the cutting feed direction and the vertical direction, respectively. Next, each member disposed on the tape 1v (2) side, which is seen through in a four-circular shape with its long sides inclined when viewed from the cutting feed direction, will be described.

That is, first, a positioning mechanism for the workpiece m is provided at the rear end of the tape /l/ (2) in FIG. 4, and this mechanism can freely appear and retract from the rear end of the tape tv (2). A contact plate (0) is provided, and when this contact plate (to) protrudes, it is arranged so that its contact surface is parallel to the running direction of the sliding guide (3), that is, the reciprocating direction of the cutter 〇η. .

The contact plate 0 is fixed to the piston rod of the hydraulic cylinder 01, which is installed upward in the frame (1), via a stay (A), and when in operation, the contact plate It protrudes by about ¥n.

Also, a table (2) that does not hinder the installation of the workpiece material m.
An adjusting means for determining the depth of cut is provided at the corner of the slide guide (8), which is shown in FIGS. 5 and 6. That is, a concave groove (A) is bored in the front-rear direction of the cutter α, and a slide plate l! is inserted into this concave groove (A). 21). Then, a model piece is fixed to the top of one end of the slide plate Qυ, and a model piece (A) (1) of the same thickness is attached to match the end face shape of the workpiece material.
A) is positioned according to the contact plate 0.

The symbol (e) is a dimension scale provided on the top surface of the slide plate Ql), and the symbol (c) is a 0 index provided on the table surface in correspondence with the dimension scale (to).

Further, in the embodiment of the present invention, F of table (2)
