Chipless cutting machine RS25CNC

The chipless cutting machine RS25CNC is used for the cutting of burr-free pipe sections out of plastic, steel or non-ferrous metals.

  • Ø 3 – Ø 25 mm
  • up to 1 mm wall thickness separable
  • repeat accuracy 0.05 mm
  • moulding cycle approx. 1 - 5 sec. depending on material and wall thickness

The chipless cutting machine RS25CNC represents a consistent enhancement of existing systems for the production of pipe sections.

The handling of the machine is very simple. The pipe is inserted into the opening, usually positioned with the help of a pneumatic gripper, and moves stepwise towards the appointed cutting position.

The pipe stands still while the radially closing cutting parts are turning around the pipe axis.

The corresponding working parameters can be stored and managed in the machine control system. The user interface allows easy and logical operation. All essential processes are electronically monitored and the data is stored in the control system. This ensures high process safety and reproducibility.
