Claims

[Claims for Utility Model Registration] 1. On the rear surface of a surface plate having a processing table, a first rail in the left and right direction and a first rail rotated by a first motor are provided.
Feed screw shafts are arranged in parallel, and a lateral moving body that is moved by the first feed screw shaft is installed on the first rail, and the rear part of the support arm is placed on the lateral moving body in a horizontally used state and an upwardly lifted state. A second rail in the longitudinal direction and a second feed screw shaft rotated by a second motor are arranged in parallel on the support arm, and a second
A front-rear movable body that is moved by a feed screw shaft is installed, and a third rail in the vertical direction and a third feed screw shaft that is rotated by a third motor are installed in parallel with the back-and-forth movable body, and a third rail is mounted on the third rail. 3. An elevating body that is raised and lowered by a feed screw shaft is installed, a cutting torch of a plasma cutting machine is installed facing downward on the elevating body, and a supporting arm is placed in a lifted state between the supporting arm and the transverse moving body. A plasma cutting machine characterized by being provided with a holding device that can hold the machine. 2. The holding device is characterized by being constituted by a tension spring tensioned between the support arm and the transversely moving body so as to cancel out the rotational moment about the pivot point due to the weight of the support arm, etc. A plasma cutting machine according to claim 1 of the utility model registration claim. 3. A request for registration of a utility model characterized in that the holding device is constituted by a cylinder interposed between the supporting arm and the transverse moving body so as to swing the supporting arm between the use state and the lifted state. The plasma cutting machine according to item 1.
