Also, as the second link panel 232 advances away, the processing unit 1 is smoothly moved by the guide heel 24 and mounted on the main table 3 and the expansion table 4. It is to cut a small plate.

On the other hand, the plate having a rather large length and width compared to the area of the expansion table 4, as shown in Figures 2 and 6a, the side mounting of both sides of the large plate of the auxiliary mounting means (5) The second binding bracket having the extension working platform 51 and the first and second extension bases 52, 52 ', 53' for reinforcement are provided at the front side and one end of the extension table 4 ( 41) and the adjustable fastener 54 for fastening and fixing one side of the plate to set the cutting position, respectively, mounted on the second fastening bracket 41, which is provided at the other end of the extension table 4, respectively. By doing so, it is possible to determine the processing position of the large plate and to securely mount.

Here, as shown in Figure 6b, by varying the length of the extension work platform 51 and the plurality of first extension stages 52, 52 ', the length in the advancing, retreating direction of the processing unit (1) It is a matter of course that processing of a larger plate can be easily performed.

On the other hand, in order to process not to simply cut (process) across the plate but to have a specific inclination angle, as shown in FIG. 7, the main table 3 seated on the extension table 4 is shown. It rotates in the radius part 4a, and it sets so that the advancing / removing direction of the said processing unit 1 may be twisted with a board | plate material.
