Roll-forming machine RF50CNC

Roller-burnishing machine RF50

The roller-burnishing machine RF50 – roll-forming machine - is used for:

  • roll-forming of shells with cables or sleeves
  • roll-forming of cases with plugs
  • roll-forming of sleeves and pipes
  • roll-forming of sensors with cables

The roll-forming machine guarantees a form-fit connection which helps achieve, among other things, better strain-relief or tightness. 

For workers of rotationally symmetric components the roll-forming machine RF50 represents a consistent enhancement of existing systems for the roll-forming of pipes, pipe ends, sleeves, shells, armatures and many other applications.

A typical example is the implementation of sensor sleeves which mechanically protect connection leads from being pulled out and seal them at the same time (IP67 possible). This procedure also allows rolling of plugs into sensor sleeves and many more. Wall thicknesses of 0.2 mm up to approx. 2.0 mm with a diameter of 10 – 50 mm are possible.

Machine setup

The handling of the roll-forming machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a die grinder. A big advantage compared to other systems is that the work piece does not move while the tools roll around its 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.
