I Description of NC coil copper tube straightening cutting and flaring machine
This machine is for straightening coil copper pipes, detecting length, burrless cutting and flaring one tube end automatically.
This machine adopts pull-apart cutting technology which is the most advanced cut-off method in the world, which eliminates or minimizes pipe ID reduction that could occured and brings burr-less cutting result as well.
This machine has two cutting stations, each station can cut two same size pipes simultanenously. Pipe size in two stations can be different.
II Main features of NC coil copper tube straightening cutting and flaring machine
- Integrated straightening, cutting and flaring together, saving labor and transmitting cost
- Servo feeding, stable and high re-positioning precision
- One time cutting four pieces, high efficient
- Adopting pull-apart technology, less pipe end ID reduction ratio
- Orbited cutter with spray lubricant, burrless cutting
- PLC control, high automation-auto feed, auto cut, auto unload, auto alarm.

* 1- 2+2 means there are two separate driving system for cutting 2 pairs tubes in different diameter and different length.
* 2- When cutting length is less than 100mm, there will be no pre-stretching function.
* 3- Pipe end ID reduction ratio means: f= (d1-d0)/d0%
