I Main features:
- Servo feeding, accurate cutting length tolerance
- One time cutting four pieces, high efficient
- Pull-apart method eliminates ID reduction of tube end
- Clean, chipless and burrless cutting, no need further end processing
- PLC control, high automation—auto feed, auto cut, auto unload, auto alarm.

* 1- 2x2 means there are two separate driving system for cutting 2 pairs tubes in different diameter and different length; 1x4 means there is only driving system for cutting 4 tubes in same diameter and length, two different options.
** 2- When cutting length is less than 100mm, there will be no pre-stretching function.
*** 3- Tube end ID reduction ratio means:
f= (d1-d0)/d0%
3.1 Pay-off device: active decoiling, with clutch
3.2 Straightening & rounding device: straightening deformation can be adjusted for different hardness copper tubes. When size changing, rounding wheel and straightening wheel will be changed.
3.3 Feeding device: driven by servo motor; Pulling and clamping dies are driven by enhanced pneumatic cylinders.
3.4 Cutting device: orbital-notching + stretching method, pneumatic driving feeding stroke of orbital blade, stable feeding and quick returning; The feeding stroke can be fine adjusted to assure same mouth shrinking rate; Equipped with lubricant spraying device for lengthening blade life.
3.5 Unloading table: covered with stainless steel, 1500mm long
3.6 All the clamping dies are made by chrome steel, quenched HRC 50
3.7 Control system: PLC + touch screen
