625XVSJS

625X Variable Speed CNC Spindle Series

The patented double turbine 625XVS JS (3/4” / 20mm Straight Shank) delivers constant high speeds and power under load. Easily switch between speeds of 30,000 and 50,000 rpm, with 0.76 hp (0.57 kW) in twin turbine mode. Speed up your cycle times with this compact and powerful spindle. Ideal for contouring, mold making, milling, finishing and drilling with small tools. Direct drive means low heat, no duty cycle and super reliability. Selectable rear or side air feed.

 

This Flexible Spindle Can Easily Change Speed and Power Ratings

Simply insert a hex key through the air shaft at the back of the spindle and turn the flow control screw up or down to switch speeds.

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.

Retrofit Any CNC with High Speed

We retrofit any CNC machine to mill at a constant high speed 24/7 – so any CNC can be a high-speed machine. This includes, but isn’t limited to DMG MORI, Haas, Fanuc Robodrill, Doosan, Hermle, Hurco, GROB, Brother Okuma, Makino and Mazak. Easy installation using selectable air feed inlets – choose side inlet NPT / Stop Block or center through shank/tool holder air feed. HSK, CAT, BT, and DIN Toolholder options are available.
