We use tubes in countless medical devices and we add new ones every day. fueled in part by the growth of minimally invasive surgery and the commonplace use of stents. The sheer number and diversity of devices is rapidly increasing—and with it, the demand for more and more laser-cut stents; flexible tubing, needles; biopsy devices; and other minimally invasive tools.

Replace legacy cutting machine
Firstly, YAG lasers is for decades have been great workhorses.Cause they have performed well and been excellent manufacturing centers for many companies.
While we update many of these systems to fiber lasers. However they still have old stage sets that are a number of generations behind current technology. In addition, they are running on slow and aging controllers with legacy software.
Simply put, the laser, stages, controller, software, water systems. Here is a brief overview of improvements.It is enable faster and better cuts with higher production rates and less downtime.
Fiber Laser
The pulsed Nd:YAG lasers used in the past years. It has been superseded by fiber lasers with better beam quality that does not change with pulse energy and average power. This provides a smaller and more consistent focused spot size.Which offers tighter cutting tolerances, with spot sizes down to 10µm, the ability to cut much finer detail features. These lasers provide pulse frequencies up to and beyond 5kHz and pulse widths down to 20µs to enable energy input optimization for a wide variety of tube materials and wall thicknesses.
Fiber Laser tube pipe cutting technology
Now fiber lasers use microsecond pulses.It offers a cutting speed and edge quality that is sufficient for many applications. Fiber laser is very short pulse duration, combined with peak powers into the gigawatt level, offers a unique cutting capability. And also, the fiber laser has a fusion cutting mechanism, whereby the laser pulse melts the metal.It is then ejected from the part by high-pressure gas. The very high peak power of the fiber laser and a pulse duration that is shorter than the material's conduction time creates a nearly pure vaporization mechanism. Since there is no melt creation during the cutting process, there is no burr, which is beneficial for such materials.
Fiber Laser tube cutting technology offer significant advantages and capability over legacy machines.It increases productivity and enabling product innovation with better process capability. Whether using the fiber laser, improvements to motion, controller and control software.It provide new capability for future manufacturing needs.
