Okuma America, Charlotte, N.C., recently introduced the MU-4000V, a 5-axis vertical machining center said to be ideal for 5-axis multi-sided machining within the aerospace and die/mold industries. The MU-4000V reportedly offers high-speed, process intensive machining combined with turning and 5-axis multitasking machining.
This versatile machine features a large work envelope and substantial base in a compact footprint. Its sturdy design boasts a machine mass of 9,700kg, while the B-axis trunnion is fully supported so there is no overhanging mass. Plus, fully supported axes construction allows for a broad scope of spindles ranging from 12,000 rpm to 25,000 rpm to efficiently handle complex and difficult-to-machine materials.
The unique and automation friendly design places the pallet changes at the back of the machine, allowing easy connection to a palletace flexible manufacturing system or pallet pool, delivering high productivity in addition to high accuracy. ATC’s can be configured to meet growing demands with 32- to 64-tool chain magazine systems and 64-plus matrix cabinets.
The MU-4000V can be equipped with Okuma’s exclusive Super-NURBS function, enabling high-feed rates and ultra-fine finishes. Standard 5-Axis Auto Tuning System technology automatically measures and compensates for up to 11 geometric errors to ensure precision machining.

- flexible manufacturing system ( FMS)
flexible manufacturing system ( FMS)
Automated manufacturing system designed to machine a variety of similar parts. System is designed to minimize production changeover time. Computers link machine tools with the workhandling system and peripherals. Also associated with machine tools grouped in cells for efficient production. See cell manufacturing.
- machining center
machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
- precision machining ( precision measurement)
precision machining ( precision measurement)
Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
- work envelope
work envelope
Cube, sphere, cylinder or other physical space within which the cutting tool is capable of reaching.
