1 CNC/GDZ—4000 flame multiple-head cutting machine  

1.1 Structural principle

Application: 

CNC cutting machine can cut plates in arbitrary shape. Several cutting torches which are used to cut strips are fixed on the other side. As the steel plate can be heated and cooled at the same time, the side-curve will eliminate once for all.

The construction of machine:

This kind of machine is composed of a gantry frame, main and secondary longitudinal guide rail. Both driving end and cross beams adopt box-beam welding structure whose stress has been relieved. The driving of the main longitudinal end beam adopts Japan AC servo driving system and driving speed reducer, through rack-and-pinion gearing. 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. Cutting torch also moves by AC servo electric machine to drive the Japan SHIMPO speed reducer, then use rack-and-pinion to drive.

Gas path: longitudinal and transverse cable and gas pipe all adopt the engineering plastics chain 。
