CNC cutting machine is a multifunctional thermal auto-cutting device combined microcomputer controlling, precise machinery and oxygen-acetylene gas cutting. Its CNC cutting torch can cut plates in arbitrary shape. As the steel plate can be heated and cooled at the same time, the side-curve will eliminate once for all.
This kind of machine is composed of a gantry frame, guide rail, CNC plasma/flame torch, and CNC system. Both driving end and cross beams adopt box-beam welding structure whose stress has been relieved, with compact structure and artistic appearance. The driving of the main longitudinal end beam adopts Japan Panasonic AC servo driving system and driving epicyclical and Japan SHIMPO decelerator, through rack-and-pinion gearing. At the side of driving end beam fixes horizontal directive wheels which can be used to fasten by adjusting the eccentric shaft, therefore, the stability and accuracy during the whole moving can be assured. The longitudinal guide ways firmed by pressure plate backing board and connecting sleeve, all made by high intensity track, all the contact surface of track have precision machining and accurate grinding racks are installed outside the guide way. This installation method can guarantee the straightness and parallelism of guide way. The transverse cutting torch fixed on the transverse tool carriage. Its moving also realized by AC servo electric machine made in Japan Panasonic to drive the epicyclical decelerator made in Japan SHIMPO, then use the way of rack-and-pinion driving.
