Description of Copper Tube Collar Hole Punching Machine
The copper tube flange hole punching machine is also called as copper tube collar hole punching machine or copper tube collaring machine, specially designed for punching flange (collar) holes on copper tubes in air conditioners 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 adopts two servo motors, one for feeding and another for rotating, capable for collaring at any positions on the tube.
