Roundness 0.2 mm

The existing portfolio of roller bending technology from 2-roll and multi-roll round bending machines of weil technology has been extended by another module: Tubes with smaller diameters and high-precision roundness can now be manufactured.


• Tubes Ø 30 with roundness 0.2 - 0.3 mm
• No flat zones
• Material thickness 1.0 - 2.0 mm


 

Some effort is required to produce small tubes from Ø 30 mm with a circularity of 0.2 mm - 0.3 mm

In order to produce electric motors, spacer sleeves or bushings, nothing more than the replacement of the winding mandrel of the RMA+ is required to continue manufacturing 10 minutes later.

 

  • Cycle time: 6 - 12 parts / minute

  • Diameter change approx. 10 minutes

 

Laser welding in excellent quality

The tubes are automatically clamped and welded in a laser welding machine in the subsequent welding process.

Calibration is required for even lower run-out tolerances and depending on the pipe length, a tolerance of 0.1 mm to 0.15 mm can be achieved.

High quality raw products for further processing

Ideal raw materials for the production of

  • housings for electric motors

  • spacer sleeves

  • bushings

  • filter tubes

  • silencer inner pipes

  • etc.
