Segment forming machine SF50CNC

The segment forming machine SF50CNC is used for the pressing of rotationally symmetric components (pipes, sleeves, shells) without pinch points, which can be inserted into the machine between jaws.

  • Ø 3 – Ø 50 mm compressible
  • up to Ø 2 mm wall thickness machinable
  • repeat accuracy 0.05 mm
  • moulding cycle approx. 5-10 sec.

The segment forming machine SF25CNC represents a consistent enhancement of existing systems for the processing 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. This procedure also allows the crimping of plugs into sensor sleeves. Wall thicknesses of up to 2.0 mm with a diameter of 3 – 50 mm are possible.

The handling of the machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a stopper, which assures that it does not move while the jaws move axially towards the work piece. 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.

Other applications in the fields of cutting, chipless isolation, calibration and scoring are also possible.

 

Basic machine

  • basic module with fastening holes for the reception of all functional components consists of: base panel with carrier for motor with gearing and spindle ball bearing
