How was the more then 100% improvement in cycle time achieved?

Air Turbine Spindles® are governor-controlled. Airflow increases if the rotational speed slows, maintaining the high speed under load when you start cutting – even on angles and hard materials. The constant high speed while in cut will improve your surface finishes and increase tool life while reducing production time.

No need for downtime to install our constant high speed direct drive spindles. Automatic Loading from any CNC Magazine is available.
