Komatsu NTC Zµ3500

NTC - First Zero Contact Machining Center - Zµ3500 World's first Zero Metal Contact Machine Revolutionary technological breakthrough Superior Rigidity, Accuracy and Precision Operating without linear guideways, roller bearings or ball screws, the Zµ3500 overcomes the inertia of conventional technology, as well as the compromised tolerances required for that technology to function. Zero metal contact design eliminates major sources of friction and related thermal distortion. Temperature-controlled hydrostatic oil in the hybrid spindle bearing, static pressure guides and the linear motor cooling system virtually eliminate thermal distortion saturation time. The near-absence of friction (and therefore vibration) increases precision, extends tool life and reduces noise levels. Features the world's first fluid hydro hybrid spindle - incorporating hydrostatic and hydrodynamic technologies that virtually eliminate wear and run-out.
