The boss 12 is a member having a tubular shape as a whole, which is provided with a flange portion 12a for supporting the cutter 10 on an upper portion thereof, and is formed by, for example, a bearing housing 13 attached to a frame member supporting the surface plate 3. It is rotatably supported. That is, the bearing housing 13 rotatably supports the boss 12 inside the bearing housing 13 at two upper and lower positions through bearings 14. A pulley 15 is attached to the lower end of the boss 12, and the rotation of the cutter driving motor M ₁ is transmitted to the pulley 15 by the belt 16.

Next, the stabilizer 20 which is provided so as to be housed in the concave portion 11a formed inside the cutting blade 11 of the cutter 10 and constitutes a part of the finishing head 2 will be described. This is a disk-shaped member and is fixed to one end (upper end) of the shaft 21 at the center thereof. The shaft 21 is rotatably supported inside the boss 12 supporting the cutter 10 via a bearing 22 and indirectly supported by the bearing housing 13. Further, the other end side (lower end) of the shaft 21 further projects from the boss 12 and a pulley 25 is fixed thereto, and rotation is transmitted to the pulley 25 from a stabilizing plate drive motor M ₂ through a belt 26.

The stabilizing plate 20 may be a flat plate member made of metal as shown in FIG. 4 (a), or a sand paper 23 as a finishing member is stretched as shown in FIG. 4 (b). Alternatively, as shown in FIG. 4 (c), a plurality of small pieces of sandpaper are arranged in a petal shape (reference numeral 23a), and as shown in FIG. 4 (d), a finishing blade 24 is provided. It can be taken. Therefore, it is preferable that various types of attachments are prepared as the stabilizer 20 so that they can be appropriately replaced and used according to the content of the finishing work.

Next, the surface plate 3 provided so as to surround the finishing head 2 will be described. A movable surface plate 30 is provided on the supply source side of the work W in order to set the cutting amount, and this fixed position (fixed height). ), The cutter 1
The relative dimension to the cutting action surface of 0 is set, and the cutting dimension of the work W is set. Then, a fixed surface plate 31 is provided in the direction to which the work W is supplied, that is, in the delivery direction. The finishing head 2 may be provided at only one place on the surface plate 3, or may be provided at a plurality of places. Further, the installation direction may be provided not only at the position acting on the lower surface of the work W as in this embodiment but also at the position acting on the upper surface and the side surface of the work.
