Copper Tube Bender with Collaring

This machine is integrated with collar hole punching and 3D bending functions together, full automatic, high precision and high efficiency.

It can only bend or only punch collar holes as well. Collar hole punching can be at any position of tube.

I Main features

1)The machine frame and body adopt keel structure to ensure machine with high intensity, rigidity, and stability.

2) The bending head is designed in integral box structure and bending arm adopts precise teeth chain as transmission, high precision.

3) Special clamping structure ensures enough clamping force, not to damage workpiece.

4) The core rod is of universal joint type, exempting from lubrication.

5) Hole collaring adopts special inside-pushing technology, no burr, no need further cleaning

6) Hydraulic system for clamping and core die movement, with compulsive air cooling

7) Machine has self-testing function for detecting original of X and Z axis and dead point alarming.

8) 8” LCD displayer, integrative antifouling keyboard

9) CNC controller can save 400 units programs for 400 products, G-M code, with RS232 interface

10) Program has auto-calibration function for bending angle and length, auto counting, auto alarming, power-off memory.
