Aluminum Extruded Microchannel Tube Straightening and Cutting machine

Overview

The Automatic Circular Cold Saw Pipe Cutting Machine works for copper capillary tubes with outer diameters from 1.5mm to 3.81mm. Tube straightness is ±2mm per meter. It handles coiled copper tubes of TP1/2 or equivalent standard products. The machine ensures high production efficiency, precise length, and excellent tube quality, making it essential for HVAC, automotive, and industrial applications.

Automation & Control
Automatic Circular Cold Saw Pipe Cutting Machine is equipped with a PLC and Servo control system for fully automatic operation, including:

• Tube uncoiling

• Tube feeding

• Tube straightening

• Tube cutting

• Tube unloading

The microchannel tube coil is decoiled from microchannel tube reels using an automatic synchronized uncoiling decoiler. Tubes are transferred stably at high speed through a tube feeding dancer unit.

Cutting & Straightening

• Tube cut-off can be performed by rotating or linear knives.

• High-speed operation can reach up to 120 pieces per minute (dependent on tube length, e.g., 600mm).

• The straightening and cutting system allows precise adjustment of rolling wheel distances.

• Stretch-breaking cutting ensures chipless, burr-free cuts with minimal deformation.

• Tube end nicking helps with subsequent core assembly.
