CNC laser welding is more affordable
An affordable CNC laser unit enables medical devices to be laser welded achieving high quality micro welding of a wide range of alloys including seam welding, hermetic sealing and other operations.
The StarWeld Performance, from Rofin-Baasel, enables medical devices to be laser welded achieving high quality micro welding of a wide range of alloys (including stainless steel, titanium, nitinol and other commonly used medical grade alloys) Now with added CNC capability, the StarWeld Performance can be used for accurate seam welding, hermetic sealing and other operations without relying on manual positioning

High beam quality pulsed YAG profiles finely
In medical device manufacture, pulsed Nd:YAG lasers now can do the work of profiling increasingly finer, structures.
Perfectly suited to the batch production of sensors, endoscopes, probes, implants and other devices - the Performance CNC is able to ensure consistent and repeatable positioning of weld spots and reliable overlap in seam welding.
With the patented SweetSpot Resonator, the laser gives consistent pulse to pulse stability from the first pulse to the last.
The optional Fine Welding Mode allows spots smaller than 75 microns to be made (standard range of spot sizes is 0.3 to 2.0mm), particularly useful for the joining of fine wires and foils.
As standard, the machine is fitted with XYZ axes (75 x 75 x 130mm).
An optional rotary axis (with tiltable bracket) allows cylindrical parts to be welded in various joint configurations.
A PC with Windows-based CAD/CAM and CNC front end allows the user to program in 'G' and 'M' codes, or draw welding geometries using the CAD front end, and then convert them to CNC part programs.
99 memories allow different laser settings to be stored depending on the materials used and weld-penetration required.
By removing the front cover-plates, it is possible for the operator to manually position workpieces under the laser beam for tacking or pre-assembly prior to seam welding.
For safety, the motorised axes are locked out in manual mode, to avoid risk of entrapment.
Hence the system retains the flexibility of the manual laser welding systems which have become well used in medical device manufacturing, jewellery workshops and dental laboratories.
Rofin-Baasel introduced the StarWeld Performance 12 years ago and has already shipped over 4,500 of these around the world.
A global support network means that wherever the final manufacturing plant is located, a Rofin-trained engineer will be nearby. Request a free brochure from Rofin-Baasel UK ...
