Laser Tube Cutting System

Miyachi America Corp. has released the Sigma Femtosecond laser tube cutting system.

Developed in partnership with laser source provider Jenoptik to expand the company’s cutting capabilities in the medical device industry, the tube cutter is the first of a new family of femto-powered systems based on Jenoptik’s ultrashort pulse disc laser platform. Ultrafast lasers offer a unique ability to process numerous materials without thermal effects.

The combination with the Sigma platform and proprietary Delta Motion control software, the system offers high-resolution, high-quality cutting for a range of tube and stent diameters, the company states.

Applying an ultrashort pulse width, this system uses cold ablation to cut materials, creating good edge quality. Postprocessing is minimal, with only ultrasonic cleaning required for materials like nitinol. The nearly cold-cutting process means very fine feature sizes can be cut into the thinnest material, while still maintaining mechanical and material integrity. No internal water cooling is needed for even the smallest tube diameter.
