LU4000 EX

With a history of 4-axis lathes covering more than 25 years, Okuma is known as the 4-axis leader due to the ease of programming, set-up and machine longevity. The LU EX series follows this tradition, offering high production tied with thermal stability. The LU EX series incorporates the latest in live tooling technology where the tooling is bolted to the turret (BMT-style) for optimum support and power engagement. The 12-station upper turret and 8/10-station lower turret offer plenty of tool stations allowing users to perform multiple turning operations either simultaneously or independently. The integral spindle motor provides ample power along with superior part finishes. The LU EX series features Thermo-Friendly Concept, Machining Navi, big bore spindle and turret steady rest.
