At IMTS 2014 Okuma will introduce its new LU4000 EX CNC lathe which utilizes two turrets, allowing two tools to work simultaneously, providing process flexibility as well as high removal rates. This machine is excellent for machining parts for the automotive industry. At IMTS this machine will be shown cutting a camshaft using Machining Navi for chatter reduction and tooling from Sandvik, a member of Partners in THINC.
The LU4000 EX incorporates a new 45° “box bed” with all box way construction, three point bearing support for the spindle, crown gear turret coupling for both turrets, two power ranges and the Okuma THINC®-OSP control, providing a foundation for a long production life. This CNC lathe is Okuma’s latest evolution of 4-axis turning in the 10-15” chuck class.
