Inquiry Form

This Bundy tube straightener & cutter is for straightening coil Bundy tubes and capillary copper tubes, detecting length and burrless cutting automatically.

This machine adopts pull-apart cutting technology which is the most advanced cut-off method in the world, which eliminates or minimizes tube ID reduction that could occured and brings burr-less cutting result as well.

Main Features of Bundy Tube Straightener & Cutter
  • Servo feeding, stable and high re-positioning precision
  • One time cutting two pieces, high efficient
  • Adopting pull-apart technology, less tube end ID reduction ratio
  • Orbited cutter with spray lubricant, burrless cutting
  • PLC control, high automation—auto feed, auto cut, auto counting, auto alarm.
