The Cryogenic Institute of New England Inc. (Worcester, MA) has added removal of machine burrs from PEEK medical devices to its line of capabilities. The Cryogenic Institute is an organization dedicated to the commercial application of cryogenic technologies for industry, government, and scientists. Results of trials undergone by medical device manufacturers have revealed that the Nitrofreeze process is highly effective at removing complex residual machine burrs from complex and medical parts. The method works by freezing the part to maintain essential tolerances, including surface finish and critical dimensions. Once frozen, the parts are tumbled while cryogenic-grade polycarbonate media are blasted at them to remove machine burrs. The company is offering the deburring service to device manufacturers on a contract service basis. It is also providing equipment to manufacturers for in-house parts processing.
