Copper Tube Straightening & Cutting Machine

Inquiry Form

This copper tube straightening & cutting machine is for straightening coil 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 occur and brings burr-less cutting results as well.

Main Features of Copper Tube Straightening & Cutting Machine
  • Servo feeding, stable and high repositioning precision
  • One time cutting four pieces, highly 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 unload, auto alarm
