      Cryogenics

      Breakthrough Cryogenic Design

      Cryogenic machining using the new, unique through-spindle, through-tool system cools the cutting edge more efficiently than ever before possible, enabling higher cutting speeds for increased metal removal, longer tool life or a blend of the two advantages. The liquid-nitrogen (-321°F) cooling system can also be combined with MQL (minimum quantity lubrication) to reduce tool friction and adhesion, enabling even higher metal removal rates or longer tool life. Ideal applications involve aggressive metal removal in the hardest workpiece materials, such as titanium, nickel-based alloys, and nodular or compacted-graphite iron (CGI).

        Advantages

        • Highspeed cutting of titanium, nickel-based alloys, stainless steel, compacted-graphite iron (CGI), composite materials
        • Applications show significant increase of productivity for titanium, CGI and hardened steel
        • Tool life can be increased significantly compared to conventional flood cooling
        • Nitrogen is non-toxic and not a greenhouse gas
        • For special machining requirements such as medical devices parts are contamination-free
        • Thermal control for high reliability in composites machining
        • MAG cryogenic through-spindle, through-tool cooling system uses small flow rates of liquid nitrogen applied near the cutting edge to maximize cooling effectiveness
