1. General description
The Machine is used for profile cutting the pipe terminal or pipe intersection part after the system calculation of the cutting path. There’s no need of the manual programming by the operator. The machine can work out and complete the cutting job After the operator input the intersected pipes’diameter,angle etc. the cutting surface is very good and no need for further treatment such as grinding or polish.
Configuration:
The machine is mainly consists of below units:
1. Machine base (by welded square tube structure)
2. Pipe Rotating mechanism (3-claw Chute and Rotating system)
3. Pipe (Workpiece) supporting Roller (The number depends on the pipe length)
4. Torch drive unit
5. Torch lifting unit
6. Torchdeflectionunit
7. Travel Rails (Highprecision machined steel)
8. Electrical system
