Product Description

I Description of NC coil copper tube straightening & burrless cutting machine

This 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 occured and brings burr-less cutting result as well.
This machine has two cutting stations, each station can cut two same size pipes simultanenously. Tube size in two stations can be different.

II Main features of NC coil copper tube straightening & burrless cutting machine
- Servo feeding, stable and high re-positioning precision
- One time cutting four pieces, high 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.

12	Cut-to-length tolerance	≤0.3mm /1000mm
13	Length difference between two tubes	≤0.5mm
14	Tube end ID reduction ratio	f < 25%*
15	Roundness of cut tubes	Non-roundness ≤3% (diameter ≤Ф12.7mm) Non-roundness≤0.4mm(diameter>Ф12.7mm)
16	Surface condition after cut	No apparent scratch, drawing marks; no burrs

* 1- 2+2 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.
* 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%
