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 625XVSCAT40 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

Automatic loading available using through spindle air supply with the patented collar and block TMA assembly, or tool change without the TMA on certain machines that have an air blast line or coolant channel supplying a sufficient air flow volume.
