Laser Tube Cutting

What Is Laser Tube Cutting?

Laser tube cutting is a precision, non-contact process that uses a focused laser beam to cut small-diameter, thin-walled tubing with narrow kerf widths, high edge quality, and tight dimensional tolerances. AMADA WELD TECH focuses on precision laser tube cutting for applications such as stents, catheter components, needles, and hypotubes.

Because the laser does not mechanically contact the tube, the process is particularly well suited for delicate, thin-walled tubing that could be affected by conventional mechanical cutting methods.

How Laser Tube Cutting Achieves High Precision

Laser tube cutting systems focus the laser beam to extremely small spot sizes. Combined with precise positioning and rotation of the tube, this enables the creation of small, intricate features and complex patterns in tubular components.

Precision laser tube cutting provides:

  • Very narrow kerf widths
  • Fine feature resolution
  • High dimensional accuracy
  • Clean edge quality with minimal or no burrs
  • Precision processing of thin-walled tubing
  • No tool wear, deflection, or mechanically induced stress

These characteristics make laser tube cutting particularly effective for small-diameter tubing requiring intricate geometries and tight tolerances.

Laser Sources for Precision Tube Cutting

Different laser sources can be used for precision tube cutting depending on the tube material, feature size, edge quality, and thermal requirements.

Yb: Fiber Lasers

Ytterbium (Yb) fiber lasers provide excellent beam quality and stability and are well suited for precision cutting of metal tubing with high repeatability.

Ultrafast Femtosecond Lasers

Femtosecond lasers provide extremely precise tube cutting with virtually no heat input into the part. This capability is particularly valuable for heat-sensitive materials and applications where thermal effects must be minimized.

Femtosecond laser tube cutting can:

  • Cut metal and plastic tubing
  • Produce burr-free cuts
  • Process challenging materials such as nitinol
  • Minimize thermal effects on the tube

These characteristics make femtosecond lasers particularly well suited for demanding micro-scale tube cutting applications.

Materials for Precision Laser Tube Cutting

Depending on the laser source and process configuration, precision laser tube cutting can be used with tubing made from:

  • Stainless steel and other metals
  • Nitinol and other shape-memory alloys
  • Plastics and polymers

The laser source and process parameters are selected according to the tube material, diameter, wall thickness, required feature size, edge quality, and thermal sensitivity.

Precision Laser Tube Cutting Applications

AMADA WELD TECH laser cutting systems are designed for small-diameter tube cutting applications requiring high dimensional accuracy, fine features, and excellent edge quality.

Typical applications include:

  • Stents
  • Catheter components
  • Needles
  • Hypotubes
  • Medical device tubing
  • Implantable and minimally invasive device tubing
  • Precision sensor and instrumentation tubing
  • Other small-diameter, thin-walled tubular components

The combination of fine feature resolution, non-contact processing, and precise laser energy control makes laser tube cutting well suited for manufacturing complex features in miniature tubing.
