Our Power Curve Is Inverted!
These Governed Turbines Increase Power as Speed Increases
Maintaining 25,000 to 90,000 RPM in Your Tool Path
When evaluating CNC spindle performance, the relationship between speed and delivered power is crucial. Electric, coolant and geared air spindles lose torque and power as the RPMs rise, causing performance to fade just when high-speed cutting demands the most from your tool. Air Turbine Spindles®, however, deliver a unique solution: our patented, governed air-driven design produces an inverted power curve – More power as speed increases, and an increase in air flow to maintain high speed on your toolpath.
Comparative performance is illustrated on a graph below.

Proof We Maintain Constant 50,000 RPM In The Cut
Why Is This Performance Advantageous?
Having more power at higher speeds delivers real benefits:
►
Consistent material removal rates for high-feed and micromachining operations.
►
Shorter cycle times, higher throughput, and greater profitability.
►
Superior finishes, especially on small parts with tight tolerances.
►
The ability to push deeper cuts and run faster feeds without overlooking quality or risking stalling.
The Technology Behind the Curve
This inverted power curve is not just a theoretical benefit, it’s a proven result of Air Turbine Motors, Spindles, and Live Tools® proprietary air turbine governor and ceramic bearing system. These spindles eliminate heat build-up, need no duty cycle, and maintain 2 micron precision during continuous 24/7 use. With only clean, dry air powering two moving parts, reliability and accuracy go hand-in-hand, with no maintenance-intensive components or controls.

What are the Real-World
Gains for CNC Machining?
CNC shops, automation lines, and robotic systems benefit from the inverted power curve by achieving reliable high-speed cutting in demanding sectors such as aerospace, medical device, and electronics manufacturing. This technology also enhances repeatability and improves part quality, even on the smallest geometries.
Additionally, Air Turbine Spindles, Motors, and Live Tools® enable easy, drop-in spindle upgrades that require only a single airline of 90 psi (6.2 bar) air; without the need for complex wiring or lubrication systems.
See the Results, Not Just the Claims
The difference is clear on the power curve: when plotted, Air Turbine Spindles, Motors and Live Tools® curve upward as RPM increases, compared to the downward trend of conventional spindles. This allows shops to operate with confidence that high-speed doesn’t mean low power or fading results, no matter the workload.
