Coldwater Machine named exclusive manufacturer of laser peening systems

Jan. 11, 2017
Coldwater Machine Company will integrate LSP Technologies' laser peening system into CMC-fabricated laser peening cells.

Coldwater Machine Company (CMC; Coldwater, OH), which designs, builds, and integrates specialized equipment for discrete manufacturing, has entered into an exclusive manufacturing agreement with laser processing services and equipment supplier LSP Technologies (LSPT; Dublin, OH) to integrate the Procudo 200 laser peening system into CMC-fabricated laser peening cells. LSPT is the only company in the world selling, installing, and integrating fully licensed, state-of-the-art laser peening equipment into the facilities of its customers.

Laser peening is a surface enhancement process that imparts superior reliability and performance into metal parts through improved fatigue life and damage tolerance. A high-energy laser beam is pulsed upon a workpiece to produce a controlled shockwave whose propagation yields a predictable plastic deformation within the material. The plastic deformation generates compressive residual stresses to a much greater depth than conventional shot peening, and in a more controlled pattern. The compressive stresses result in improved fatigue strength of the workpiece, along with increased resistance to foreign object damage. Laser peening has proven to extend the service lifetime of critical metal parts by over 10X that of an untreated workpiece.

CMC will build the equipment based upon the LSPT laser peening system designs. These systems can then be integrated directly into a customer production line. The laser peening systems include an IP license to LSPT's intellectual property, which allows infringement-free laser peening, customer training, ongoing equipment service, long-term technical support, and many other process advantages.
