Hairpin tube bending&cutting machine

1)This bending machine is uesd for processing pipe to long U shaped 2)High efficency 3) Easy operation 4) Dependable property

      Hairpin tube bending&cutting machine is used with AC servo motor NC system to drive to feed. The feeding is precision. The consistency of the length is good. It is also used with clamping hydraulic and bending. The angle of bending is and the run of the equipment is stable.

       It is used with PLC to control and also used with touching screen to set parameter automaticaally. The program is very easy and you can only use one switch to complete the whole operation.

       The whole machine is used with import components and the protecting function is perfenct.

Different bending dies can be changed to meet various requirements.

       Different bending dies can be changed to meet varous requirements.
