Machine tool builder Okuma America Inc., Charlotte, N.C., has joined forces with 5ME LLC, Warren, Mich., to demonstrate the advantages of cryogenic machining, including faster processing, longer tool life, increased part quality and lower environmental impact, according to the companies. The strategic partnership will establish two cryo demonstration facilities—one at 5ME's Technical Center in Warren, and the other at Okuma's Aerospace Center of Excellence in Charlotte—where manufacturers can test various machining processes using 5ME's cryogenic machining technology. Both facilities will have Okuma machines equipped with cryogenic systems that use vacuum jacketed feed lines to deliver small flow rates of liquid nitrogen through the tool directly to the cutting edge.
