the tools of a new generation™

The unmatched ability to combine the flexibility of variable speed with maintenance-free, governed power, redefines the way micro-machining is accomplished. Air Turbine Spindles® are powerful direct drives with just 2 moving parts, low heat, and have no duty cycle.

The 625XVSHSK-A63 switchable speed spindle can run at your choice of 30,000 RPM with 0.4 HP (0.3 kW) in single turbine mode or 50,000 RPM with 0.76 HP (0.57 kW) in twin turbine mode. Switching speeds is easy, just insert a hex key through the air shaft at the back of the spindle and turn flow control screw up or down to switch between the two modes.

Flexibility for multiple applications. Direct drive reliability – low heat - No duty cycle. Governed speeds that do not drop as your tool engages. Achieve 6 – 10x faster cycle times. Optimize your cutting tool performance and life. Direct drive reliability with low heat, 2μ precision - No thermal effect on accuracy. No machine spindle wear.

Automatically Load and Unload

All Air Turbine 625XVS HSK spindles can tool change automatically if the machine's air supply line has a minimum of 8 mm internal diameter through center air feed.
