Okuma America Corporation Debuts the MA-4000H
Okuma America Corporation has introduced its newest horizontal machining center, the MA-4000H. Making its first public appearance at a major manufacturing trade show, the MA-4000H is designed to draw a crowd, thanks to a blend of capability, control, and thoughtful engineering that speaks to everyday production demands.
Performance, Capacity, and Design—Working Together
The MA-4000H offers one of the most expansive machining areas in its class, giving you room to take on complex parts without compromise. Built for high performance, it’s at home in both mass production and variable-volume work, so you can pivot between repeat jobs and short runs without changing platforms. From automotive components to custom metal pieces, the machine is built to deliver consistent, repeatable results that keep your schedule intact.
Innovative Chip Management
A standout of the MA-4000H is Okuma’s proprietary “sludgeless tank” chip and coolant management system. By dramatically improving chip discharge, it helps prevent the buildup that slows down cycles and forces unplanned stops. The effect is simple: fewer interruptions and longer, smoother runs—especially when machining intensifies and the chips start piling up.
Advanced Control System
At the core is the new OSP-P500 CNC control with a dual-core processor. This advanced control drives accuracy while boosting overall machining performance. Because it’s built on an open-architecture platform, you can integrate applications from Okuma’s App Store, letting the MA-4000H adapt to your workflow and your shop floor—rather than the other way around.
Live at the International Manufacturing Technology Show
The MA-4000H will be shown in Okuma’s booth at this major manufacturing event, with experts on hand to walk through its capabilities. Expect live demonstrations that include machining electric vehicle battery housings as well as custom cornhole game boards—two very different parts that highlight the machine’s power, speed, and flexibility in real-world use.
Key Specifications That Matter on the Floor
If you’re sizing up the MA-4000H for your operation, these specifications offer a clear snapshot of its capacity and pace:
- Max Machining Travels: 22.05 x 25.59 x 26.97 inches
- Rotary Pallet Size: 15.7 x 15.7 inches
- Max Speed: 15,000 rpm
- Spindle Power: 51 hp
- Rapid Traverse: 2,362 ipm
Taken together, these numbers show a machine built to move quickly between features, accelerate part changeovers on a compact pallet, and hold its own on both speed and power. In practice, that means shorter cycle times and the latitude to tackle a wide mix of parts without changing your setup philosophy.

Frequently Asked Questions
What sets the MA-4000H apart from other machines in its class?
It combines one of the largest machining areas in its class with high-performance capability, making it a fit for both mass production and variable-volume work. That mix of capacity and flexibility is the point.
How does the “sludgeless tank” chip and coolant system help day to day?
It improves chip discharge to prevent accumulation, which reduces stoppages. In practice, you get longer uninterrupted runs and more predictable output during heavy machining.
What does the OSP-P500 CNC control bring to the table?
The OSP-P500 uses a dual-core processor to support high accuracy and strong machining performance. Its open-architecture platform also lets you integrate applications from Okuma’s App Store so the control can adapt to your workflow.
Where can I see the MA-4000H running live?
You can see it at the International Manufacturing Technology Show in Okuma’s booth. Live demos include machining electric vehicle battery housings and custom cornhole game boards to showcase speed, power, and flexibility.
Why consider Okuma as a single-source provider?
Okuma designs the machine and the control to work together from the start, aiming for reliability and performance. With roots in the late 19th century in Japan and a continued focus on innovation and sustainability, the company builds systems meant for modern manufacturing.
