Constant Governed High Speed and Torque

Automatic Loading of 65,000 RPM Air Turbine Spindles® on Hermle C30U using Center Air Feed

25,000 – 90,000 rpm – power to 1.4 hp

Air Turbine Spindles® utilizes a unique patented direct drive with no vanes, gears or brushes to wear, burn or break. Dramatically reduce your cycle times, and optimize cutting tool performance and life on your Hermle.

Most of the problems that occur in micro machining come from a lack of RPM and poor dynamic runout. Air Turbine Spindles® uses the highest quality runout and balancing systems on the market today. This creates the best dynamic runout accuracy and governed high-speed precision.
