Cooled by turbine air for 24/7 operation. No oil or control system required. No Duty Cycle.


Keep continuous tool path engagement on your existing CNC at high speed even in angles and hard material. Ideal for micro machining with speeds of 25,000 – 90,000 rpm with power to 1.40 hp.

Most of the problems that occur in micromachining come from a lack of RPM and poor dynamic runout. Air Turbine Spindles® use the highest quality runout and balancing systems on the market today. This creates the best dynamic runout accuracy and governed high-speed precision. No need for operator downtime. Automatically load Air Turbine Spindles® with our wrap-around Toolchanger Mounting Assembly into your Hurco VM/VMX.
