625XVSNS
Variable Speed Spindle Series
The 625XVS NS produces superb accuracy and fast results. Rated governed speeds available are 30,000 and 50,000 rpm with power to 0.40 hp (0.30kW) and 0.76 hp (0.57kW). The 625XVS NS features no shank and air feed from the rear position. Drop-in 57mm fixture ready to mill, finish or drill at high speed. Front ends sealed for wet environments (rear exhaust not sealed). Compact and powerful Air Turbine Spindles® 625 unit delivers patented constant governed high-speed operation under load cuts faster and cleaner – speeding up cycle times and achieving major savings. Fewer moving parts mean less vibration and fewer repairs. There are no gears or vanes to lubricate or burn up and the ceramic grease-packed bearings are durable. Specify angular bearings for drilling. Totally oil-free operation eliminates workpiece contamination and oil lubrication using 90 PSI (6.2 Bar) dry clean oil-free air.
X = Double Turbine Power. No Duty Cycle. The hex key inserted through the rear of the spindle switches the position of an internal screw – controlling the flow of compressed air to supply one or both turbines operating at different speeds with single or double turbine power ratings.

How do I change the speed?
Our patent-pending system makes it very easy to change speed and power rating in a minute with our patented double turbine. A hex key fits through the air shaft at the back of the spindle. The flow control screw is turned up or down by the hex key to switch speeds, as displayed below in the red and green positions below.
