The U.S. Patent Office recently granted Nashua, N.H.-based Resonetics a new patent (U.S. 9,132,585) “Laser Machining System and Method for Machining Three-Dimensional Objects from a Plurality of Directions.” According to the company, the patent addresses the challenge of switching quickly from one location on the work piece to another by moving the laser beam instead of rotating the work piece.
Beam movement can be enhanced by using small galvo-driven mirrors in the path of the beam. This method replaces the costly scan lens with an inexpensive set of simple lenses. The tooling for this new method must only hold the part steady in one position, making it simpler, lighter and more economical, company officials said.
“The technical team at Resonetics has developed a novel solution to address unmet customer needs for quality, speed and cost-effectiveness,” said Tom Burns, CEO.
Resonetics provides laser micromachining contract manufacturing services for medical device and diagnostic companies.
