Microchannel Aluminum Tube Straightening & Cutting Machine

I Description:

Parallel-flow condenser & evaporator in automotive air conditioner uses microchannel extruded aluminum tube which is also called as multiport tube.

This machine is specially designed for decoiling reel shaped microchannel aluminum tube, straightening and cutting to length automatically.

This machine adopts special nicking & pull-break cutting technology, chipless, burr free and very small deformation on cutting section.

And the machine has special function for nicking tube ends which is good for further core assembling.

This machine can cut two microchannel aluminum tubes simultaneously.

II Main Features:

- Servo feeding, stable and high re-positioning precision

- One time cutting two pieces, high efficient

- With special stretch-breaking cutting function, less mouth shrinking rate

- PLC control, high automation – auto decoiling, auto feeding, auto cutting.
