625XVSBT40
625X Variable Speed CNC Spindle Series
The patented double turbine 625XVSBT40 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.

Automatically Tool Change on your CNC
Automatically load Air Turbine Spindles® in CNC machines with our patented wrap-around Toolchanger Mounting Assembly (TMA). This option allows CNC tool-changers to automatically load/unload our family of high-speed precision spindles using a proprietary collar system and mounting block or ring around the CNC spindle integrated to the right side of the CNC spindle in minutes.
Screw In Mounting Block
Two Piece Ring and Block
Drill Tap
Mounting blocks or rings compatible with Haas, Hurco, Doosan, Robodrill, Hardinge, DMG, Brother, Okuma, and all other CNC’s are available. We are accustomed to developing custom solutions for any CNC. A Universal Block can be provided for drilling your CNC screw positions. Installation Kits are available. The TMA block remains on the CNC spindle for normal tool changes, even if not using the Air Turbine Spindles™ as it will not interfere when using the main spindle.
TMA Assembly Includes
- Mounting block or ring assembly
- Spindle manifold collar with adjustable height connector to block
