Okuma MV-4000H

The Okuma MV-4000H is a compact horizontal machining center designed for high-productivity four-face machining of medium-size prismatic components. Its horizontal spindle orientation allows chips to fall away from the workpiece by gravity, resulting in better surface finishes and longer tool life compared to vertical machining configurations on deep-cavity parts.

Built around a 400 mm pallet, the MV-4000H is well-suited for aluminum automotive components, hydraulic blocks, gearbox housings, and pump bodies where multiple faces must be accessed in minimal setups. The machine's rigid construction and precision linear guideways deliver the accuracy and repeatability expected in high-volume production environments.

Okuma's OSP-P300S control manages the pallet indexing, tool changes, and multi-face machining programs with ease. Optional pallet pool automation allows the MV-4000H to run lights-out for extended periods, maximizing spindle utilization and reducing per-part costs significantly.

The MV-4000H occupies a smaller footprint than larger HMC models, making it an attractive entry point into horizontal machining for shops transitioning from vertical machining centers or seeking to expand their HMC capacity without major facility changes.
