I Description of CNC copper tube flange hole punching machine
This machine is specially designed for punching flange holes on copper tubes in AC conditioners, refrigerators and solar heaters.
This machine adopts "extruder system", forming collars by pushing-out from tube inside, different to T-drill technology. Collar hole mouth is clean and even, no need further processing. So it is suitable for large scale production.
This machine is 2-axis servo motor driving, capable for punching flange holes on any positions of the tube (usually in two rows).
II Main features of CNC copper tube flange hole punching machine
- Servo feeding,hydraulic punching, high precision and stable
- PLC + HMI, full automatic, only manual loading & unloading
- Good punching & drawing result, high efficient
- Medium-speed wire cut molds, more than 100,000 times punching life
