Five-Axis VMC Provides Stable Design, Error-Compensating Technologies

Okuma’s MU-4000V vertical machining center is designed for five-axis multi-sided machining applications in the aerospace and die/mold industries. It provides high-speed, process-intensive machining capabilities combined with turning and five-axis multitasking. The VMC’s sturdy design provides a large work area, and the B-axis trunnion is fully supported to eliminate overhanging mass. Fully supported axes allow for a variety of spindles ranging from 12,000 to 25,000 rpm to efficiently handle complex and difficult-to-machine materials. 

Pallet changes occur at the back of the machine, easing connection to a Palletace flexible manufacturing system or pallet pool for greater productivity. Automatic toolchangers can be configured to meet growing demands with 32- to 64-tool chain magazine systems and matrix cabinets accommodating more than 64 tools.

The MU-4000V can be equipped with Okuma’s Super-NURBS function, enabling high feed rates and ultra-fine finishes. The five-axis auto tuning system automatically measures and compensates for as many as 11 geometric errors to ensure precision machining. Built with the company’s Thermo-Friendly concept, the machining center performs consistently regardless of warmup time or ambient temperatures, the company says.
