Description
The tube cutting machine is a NC cut-to-length machine for straightening coil copper tubes and cutting it into the length required, automatically. It adopts special cutting technology, resulting in chipless cutting and small deformation of the cutting section.

Main Features of Coil Copper Tube Cutting Machine:
1. Servo feeding, stable and high repositioning precision
2. One time cutting four pieces, high efficient
3. With stretch-breaking function, less mouth shrinking rate
4. PLC control, high automation-auto feed, auto cut, auto unload, auto alarm

Microchannel Flat Aluminum Tube Cutting Machine

Description
Inside automobile air conditioners, the multi-flow condenser uses microchannel flat aluminum tubes. These tubes are also called mini-channel or multiport aluminum pipes. A microchannel flat aluminum tube cutting machine is designed specifically to straighten the coil aluminum tubes. It also has the functions of necking and automatic cutting to length.

Main Features
1. Employing servo feeding system, the coil aluminum tube cutting machine has stable and high-accuracy repositioning performance.
2. Two pieces of coil aluminum tube can be cut synchronously, resulting in high working efficiency.
3. The special stretch-break cutting function results in less mouth shrinking rate
4. Controlled by PLC, this product can complete decoiling, material feeding, and material cutting, automatically.
