Heat Pipe Automatic Tube Cutting Machine

The Heat Pipe Automatic Tube Cutting Machine is a high-speed, automated system designed for the initial processing of raw copper tubing. Unlike traditional saw-cutting methods that produce waste and burrs, this machine utilizes chipless “orbital” rotary cutting technology. By using high-hardness circular blades that rotate around the tube, it achieves a clean, mirror-like end face without generating copper chips or causing tube deformation. This is critical for heat pipe manufacturing, as it ensures the internal diameter remains perfectly round and clean for subsequent mandrel insertion and powder filling.

Key Features

  • Chipless Orbital Cutting: Uses a planetary rotating blade system that “parts” the tube rather than sawing it. This eliminates copper dust (chips), preventing internal contamination of the heat pipe.
  • Integrated Straightening Unit: Features a multi-wheel vertical and horizontal straightening system to ensure coiled copper tubing is perfectly straight before cutting.
  • Servo-Driven Length Feeding: High-torque servo motors combined with precision ball screws ensure length tolerances within ±0.05mm, even at high speeds.
  • Burr-Free & No Deformation: The cutting pressure is finely controlled to ensure the tube ends are smooth and the roundness (ovality) of the pipe is maintained.
  • Automatic Bundle/Coil Feeding: Can be configured to feed from straight bundle racks or active decoilers for coiled tubing, allowing for continuous, unattended operation.
  • Smart HMI Interface: Touchscreen control allows for easy setting of cutting lengths, batch quantities, and speed, with built-in diagnostics for blade wear and material depletion.

FAQ

Q1: What is the advantage of "chipless" cutting over traditional saw cutting?

A: Standard saw cutting creates copper dust (chips) that can clog the internal wick structure or interfere with the vacuum during the degassing stage. Our chipless orbital method uses a “squeeze and part” technique that creates a mirror-finish end with zero material loss and no internal contamination.

A: Yes. Most of our high-speed tube cutters are equipped with an active decoiler and a multi-wheel straightener. This allows you to buy material in bulk coils (which is more cost-effective) and automatically straighten it before cutting.

A: Length changes are nearly instantaneous. You simply input the new value into the Touchscreen (HMI), and the servo-feeding system adjusts immediately. No mechanical hardware changes are required for length adjustments.

A: No. Our machines feature “Floating Support” and adjustable blade pressure. This ensures that even ultra-thin tubes (e.g., 0.25mm wall thickness) remain perfectly round, which is critical for the next stage where a mandrel must be inserted for powder filling.

A: At an average speed of 2,000 pieces per hour, a single machine can produce approximately 16,000 to 20,000 tubes per 8-hour shift, making it highly suitable for large-scale heat pipe fabrication.
