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.
