Okuma Machining Centers and Lathes

Okuma Horizontal Machining Centers
Okuma Horizontal Machining Centers

Okuma horizontal machining centers are engineered to deliver the exact power and precision required to meet any requirement. The Okuma design relies on a strengthened ball screw bracket, 3-point cooling for the Y-axis, intelligent chip handling, and Thermal Active Stability (TAS) to create the most stable and accurate horizontal machining centers on the market.

Okuma Lathes
Okuma Lathes


Okuma's broad range of lathes offers a variety of bore sizes, bed lengths and optional features, 427 combinations in all. This variety allows us to create custom lathe solutions capable of meeting any production need. Many parts can be completed on a single machine. The ability to hold tight tolerances eliminates the need for separate finishing or grinding operations. Okuma's industry-leading THINC - OSP Control creates optimal operating efficiency. The Absolute Position Encoder allows for the immediate return to production in case of power loss or other machine interruption.

High Performance Motorsports / Automotive

Global competition in the automotive market continues to grow, and being successful means producing long run and short run parts efficiently, accurately and on time. Durable and reliable Okuma machining centers and lathes give you the capacity and flexibility you need to compete effectively, and, when used in conjunction with the THINC-OSP control, manufacture parts quickly, with accuracy and reliability. Competition in the field of motorsports also continues to grow. Okuma machine tools are setting the standard for high performance in the production of racing engine components—pistons, cylinder heads, camshafts, and wheels—with precise dimensional control for quality, reliability and durability. In 2004, we formed the Okuma High Performance Motorsports industry team to develop the machining technology that gives shops a competitive edge in the production of precision performance components. The lessons we’re learning here translate into improvements in technology for virtually every type of precision machining application.
