Air-driven spindles deliver high speed and constant power.
Air-driven, high-speed turbines from Air Turbine can turn any machine into a high speed machine. Stored in the tool changer, the high speed spindle loads into the machine’s main spindle.
The spindle maintains even torque and constant high speed across the tool path at 25,000 to 90,000 rpm with power up to 1.4 hp. A proprietary governor modulates air flow with spindle load for consistent low tolerance performance.
The results are revolutionary – constant high speed and torque under load at 2 micron precision delivers dramatically faster cycle times. Now, your tool maintains constant high rotational speed in angles and hard materials.
Air Turbine Spindles patented direct drive turbine has only 2 moving parts, resulting in exceptionally low vibration and heat. Constant airflow cools the ceramic bearings, resulting in no thermal expansion within the device. With no high frequency brushes or gears to burn up, nor cumbersome control system, the spindle unit can deliver constant operation and a full duty cycle.
The air powered spindle requires 90 PSI of shop air and can accelerate feel rates to over 3,000 inches per minute with any tool up to 1/4 inch. The unit is available in multiple thank configurations: CAT, DIN, BT and straight shank. Air Turbine Spindles are manufactures in the United States and can retrofit any CNC machine. Prices start at $3,950.
