CNC Chipless Cutting Machine

Machine drawing of the CNC tube chipless cut-off machine

The CNC tube chipless cut-off machine is used to decoil, straighten and chiplessly cut-off copper and aluminum coils for the pipelines of air-conditioners, water heaters, aircrafts, automobiles, etc.

  • CNC Tube Chipless Cut-Off Machine
  • Cutter - rotating, chipless cut
  • Single - side motorized decoiler (expansion type) suitable for coils with wooden reels. It is often used for copper aluminum tubes in the automotive industry
  • Straightener
  • Aluminum tube
  • Copper tube

Features:
1. Servo CNC control, accurate locating, stable feeding.
2. High precision, high degree of automation.
3. With chipless cut-off function, it reduces the tube end shrinking rate.
4. Easy maintenance, pneumatic components control, less lubrication points, pollution-free, easy to clean.
5. Easy operation.
6. Can process simultaneously two different specifications of copper tubes (two tubes for each specification), two-sided cutting.
