90° Spindle Series

Improve your cycle times dramatically and maintain continuous high-speed engagement in angles and pockets with the 625X90CAT40 spindle. The direct-drive governed 90º 625X90 mills with no duty cycle at constant high speed with ultra-low vibration – improving accuracy and rigidity. Rigid steel construction in one piece with the tool holder reduces the height of the unit. The entire motor is in the 90º head.

There are no gears or HF brushes to vibrate or burn up as in other 90º heads. Air Turbine Spindles® patented double turbines deliver extra power to 0.78 hp (0.58 kW) to maintain stable high speed and torque under load. Accelerate your feed rates. Select governed speeds at 30,000, 40,000, and 50,000 rpm. Ideal for mold making, milling, finishing with small cutter capacities, optimizing cutting tool life and performance. Automatic loading from your CNC Magazine for complete integration of constant high speed in your programs.

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.

Block and Collar on the Automatic Tool Changer Assembly

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.

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.
