Precision Laser Tube Cutting Systems

AMADA WELD TECH designs and builds integrated laser systems for precision micro cutting of small-diameter tubes. These systems combine the laser source, precision motion, tube handling, tooling, software, and process controls into a coordinated production solution for applications requiring fine features, tight dimensional accuracy, and high-quality cut edges.

Laser tube cutting is particularly well suited for manufacturing intricate tubular components such as stents, hypotubes, catheter components, needles, cannula, and other small-diameter tubing.

What is an Integrated Laser Tube Cutting System?

An integrated laser tube cutting system combines the laser cutting process with the equipment required to accurately position, rotate, and process small-diameter tubing.

Depending on the application, system capabilities may include:

  • Fiber or femtosecond laser technology
  • Precision linear and rotary motion
  • Multi-axis coordinated motion
  • Tube handling and application-specific tooling
  • Process controls and operator interface
  • Part capture and unloading

Integrating these functions into a single system provides the precise coordination between laser processing and tube motion required to create complex features and geometries in small-diameter tubing.

Precision Micro Cutting of Tubes

Laser tube cutting is a non-contact process, making it well suited for small, delicate, and thin-walled tubing. Because there is no physical cutting tool contacting the tube, the process avoids issues associated with tool wear, deflection, and mechanically induced stress.

The focused laser beam enables:

  • Narrow kerf widths
  • Fine feature resolution
  • High dimensional accuracy
  • Complex tube geometries
  • High-quality cut edges
  • Minimal or no burring, depending on the process

These capabilities make precision laser tube cutting particularly valuable for small tubular components with intricate features and demanding dimensional requirements.

Laser Sources for Tube Cutting

The laser source is selected according to the tube material, wall thickness, feature geometry, edge-quality requirements, and sensitivity to heat.

Fiber Lasers

Fiber lasers provide a fast, stable process for precision cutting of metal tubing and can be integrated with precision tube motion and tooling for repeatable production.

Femtosecond Lasers

Femtosecond lasers provide precision micro cutting with virtually no heat input into the part. They can produce burr-free cuts and are particularly useful for materials such as nitinol and for applications where thermal effects must be minimized.

Laser Tube Cutting Applications

AMADA WELD TECH laser cutting systems are designed specifically for precision tube cutting applications, including:

  • Stents
  • Hypotubes
  • Catheter components
  • Hypodermic needles
  • Cannula
  • Other small-diameter and thin-walled tubing

System configuration can be tailored to the tube diameter, material, wall thickness, feature geometry, production requirements, and laser process.

AMADA WELD TECH Integrated Laser Tube Cutting Systems

Both the laser process and the design of the complete system are critical to successful production. AMADA WELD TECH combines laser processing expertise with system engineering capabilities in motion, tooling, software, and automation to develop production-ready laser tube cutting solutions.

Our applications engineers can evaluate samples and process feasibility to determine the appropriate laser technology and process parameters. System engineers then integrate the required laser, motion, tooling, controls, and other functions into a solution designed around the application and production requirements.
