Chipless cutting machine RS25

The chipless cutting machine RS25 is used for:

  • chipless cutting of pipe sections

  • chipless cutting of plastic

  • chipless cutting of steel or non-ferrous metals

A typical implementation of the cutting machine is the chipless cutting of pressure sensors

from their carrier material or the cutting of flexible hoses to length. Wall thicknesses of 0.1

mm up to approx. 1.0 mm with a diameter of 3 – 25 mm are possible.

Machine setup

The handling of the chipless cutting machine is very simple. The pipe is inserted into the feed axis, usually positioned with the help of a gripper, and moved 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.

Basic machine

  • basic module for the reception of all functional components consists of: main base plate with carrier for 2 servomotors, recirculating ball screw and main ball screw
  • cutting head available in 2 versions
  • option 1: 3 cutting part holders, W > 0.5 mm, Ø > 8mm
  • option 2: 1 cutting part holder and 1 counter roll holder with counter roller, W < 0.5
