CNC Copper Tube Bender

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

6) 8” LCD displayer, integrative antifouling keyboard

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

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