Retrofit Okuma CNCs and Lathes with
Constant Governed 25,000 to 90,000 RPM and Torque

Air Turbine Tools® and Okuma America Corporation have partnered to deliver patented high-speed machining technology to Okuma CNC machines and lathes.

A simple connection to 90 psi air is all that is required and full ATC is available.

Now Okuma users can integrate Air Turbine Spindles®, Air Turbine Live Tools®, and Air Turbine Motors® seamlessly into their machines, enabling constant high speed milling at governed constant speeds of 25,000–90,000 RPM with power to 1.4 HP and 2 micron accuracy.

How Does Air Turbine Spindles® Reduce Your Cycle Time?

Tools under ¼” (6 mm) require high RPM to achieve proper SFM and prevent tool breakage and wear. Once connected to a 90 psi air supply, the spindle instantly accelerates to its rated speed. The patented built-in governor automatically increases airflow under load, maintaining both the RPM and power in cut without heat or thermal growth that is confirmed by third party testing.

“One of the key benefits to Air Turbine Spindles® is the ability to add 25,000 to 90,000 RPM directly to your Okuma CAT40 15,000 RPM spindle.”

– Joe Grigg, Applications Engineer, Okuma America

This proprietary design is what enables continuous 24/7 operation with no duty cycle and 2-micron accuracy by regulating airflow to maintain both RPM and torque in hard materials and complex tool paths. This will expand your Okuma machines’ capabilities to perform as high-speed, high-precision machining centers without any additional wiring, control boxes or maintenance.
