Product Detail

Our LB4000 EX II 2-axis turning center is built on Okuma’s Thermo-Friendly Concept to ensure minimal thermal growth, and slant-bed box construction translates to unsurpassed quality and rigidity. Equipped with Okuma’s high-power, high-torque PREX motor, this machine delivers high-quality machining from heavy- to high-speed cutting with a through-hole diameter able to accommodate larger workpieces. The operator-friendly, open-architecture OSP-P control makes this machine not only easy to operate, but also to integrate with other peripheral equipment. A wide variety of bed lengths, bore sizes, and options—including live tooling and Y-axis—means there is a configuration to meet any shop's requirements.
