る。Next, the operation of the plasma cutting machine 1 configured as described above will be described. The cutting torch 30 is processed by driving the torch support frame 17 back and forth, moving the torch head 25 left and right, and moving the cutting torch 30 up and down by driving the drive motors M1, M2, and M3 forward and backward.
To move three-dimensionally. The dust generated during the processing by the cutting torch 30 may soar above the processing table 5, but in this case, the soared dust accumulates on the surfaces of the cover member 21 and the auxiliary rail cover 34. Therefore, dust is not directly accumulated on the surfaces of the auxiliary rail 33, the front-rear guide rail 7, and the front-rear ball screw 8, and the auxiliary roller 32, the front-rear slider 9, the front-rear nut body 1
There is no inconvenience in the guidance of 3. Further, the torch support frame 17 is formed in a substantially L shape, and the front and rear sliders guided by the front and rear guide rails 7 fixed to the machine frame 3 are provided at the lower end of the front and rear slide body 15 which is a vertical portion of the torch support frame 17. 9, the auxiliary rail 33 fixed to the machine frame 3 side is attached to one end of the support arm 16 which is the horizontal part of the torch support frame 17.
Since the auxiliary roller 32 guided rotatably is rotatably supported, most of the own weight of the torch support frame 17, the torch head 25 and the like is received by the front and rear sliders 9, and the remaining slight weight is received by the auxiliary roller 32. Even if an operator mistakenly applies a downward load to the left end of the support arm 16, this load is received by the auxiliary roller 32, so that the support arm 16 can be prevented from bending and the processing accuracy does not deteriorate. Furthermore, only one front / rear guide rail 7 for supporting the front / rear movement of the front / rear slide body 15 with respect to the machine frame 3 needs to be provided, and an inexpensive plasma cutting machine can be provided.

な粉塵の吸引回収を行なうことができる。As described above, in the dust collector of the fusing and cutting machine of the present application, the shutter for opening and closing the communication state between the main duct and each dust collecting opening is moved between the open position and the closed position. Provided freely, an elastic body for always holding the shutter in a closed position is provided, an engagement / disengagement member is provided on the shutter, and the torch support frame is engaged with the engagement / disengagement member by the forward / backward movement of the torch support frame, Since the cam surface for moving the shutter of the dust collecting opening corresponding to the front-rear direction position of the torch support frame to the open position is provided, without using a solenoid or an electric control device for controlling this unlike the conventional case, Even if the suction force of the dust collector connected to the main duct is weak, the dust can be reliably sucked and collected.
