Okuma says its MB-4000H is a high-speed, thermally stable horizontal machining center that offers quick acceleration, fast tool changes and high power to maximize moldmaking productivity within a minimal footprint. This machine can be equipped with space-saving, large-capacity, automatic toolchangers and flexible manufacturing systems to increase shop floor production. The flexibility of this machine makes it well-suited for use in the aerospace, oil and gas and automotive industries.
The MB-4000H (part of Okuma’s Affordable Excellence program) can be outfitted with either a 15K- or a 20K-rpm spindle. The range of spindle options makes this horizontal machining center ideal for high-speed, precision machining of molds, aluminum and exotic materials and for high production industries. When equipped with Okuma’s Turn-Cut functionality, it can perform turning functions, allowing it to complete complex parts, such as valves, without having to move the parts to a secondary machine.
Equipped with the OSP-P300M control, when connected to the internet, the MB-4000H can easily connect to the Okuma App Store, where users will find a variety of productivity enhancing machine tool apps.
The MB-4000H is built using Okuma’s unique Thermo-Friendly concept. This technology minimizes thermal deformation caused by extreme temperature changes, ensuring high accuracy machining and energy efficiency.

- 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.
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.
