For Widely Varied Parts in Small Lots

The MU-4000V 5-Axis CNC Vertical Machining Center combines high efficiency and accuracy to deliver high quality work-pieces with many machined portions. Simultaneous 5-axis surfacing and turning enables one-chuck multi-sided machining plus outstanding surface quality and dimensional accuracy. With one of the largest work envelopes in its class, this machine provides the flexibility to handle a wide range of work-pieces while maintaining the most compact footprint possible.

This MU-4000V builds on Okuma’s expertise in double column design, highly accurate, highly rigid machining centers, and full 5-axis cutting capability. The machine provides easy access to the working area and loading position, reducing operator burden during setup. Long-term capabilities are enhanced by the availability of peripheral equipment including pallet pools and matrix automatic tool changers.

A high speed, high power motor is available with either CAT 40 or HSK A-63 taper spindles and the option of turning mode on the C axis table for added processing capability. This model incorporates a high-speed 32-position automatic tool changer and 1968 ipm rapid traverse, resulting in a powerful production capability.

The MU-4000V includes the latest full 5-axis simultaneous control system, the OSP-P300. The control offers functionalities such as the patented OSP absolute position encoders, which do not require a zero return, and the latest Easy Operation screens and software.

Take advantage of a full range of Intelligent Technologies including Thermo-Friendly Concept, Collision Avoidance System, Machining Navi, and 5-Axis Auto Tuning System. This machine is well-suited for the aerospace and die/mold industries.

The MU-4000V was named one of the Best 10 New Products of 2015 by Nikkan Kogyo Shimbun’s Business & Technology Daily News.
