Variable Speed Series
Integration of the popular DIN40 tool holder into the 650 spindle housing delivers constant high speed with ultra-low vibration and improves accuracy and rigidity. Rigid steel construction in one piece with the tool holder also cuts the height of the unit. With Air Turbine Spindles® patented double turbine’s extra power the 1.4 hp (1.04 kW) motor maintaining stable high speed and torque under load. The 650XVSDIN40 accelerates feed rates and cuts cycle times as a result of its low friction power unit with few moving parts. Rated governed speeds available are 25,000 to 40,000 rpm. Plenty of power to speed up your inches cut per minute. High cutting speeds are maintained at the periphery of your end mill or burr using the 650’s unique governed performance to achieve a faster cycle time, a cleaner finished surface and more production on your CNC. 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.

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
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
