90 Degree Series
Improve your cycle times dramatically and maintain continuous high speed engagement in angles and pockets. The direct drive governed 90º 625X90 spindle 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 toolholder 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, 50,000 and 65,000 rpm. Ideal for mold making, milling, finishing with small cutter capacities, optimizing cutting tool life and performance. Compact and reliable Air Turbine Spindles® operate with only 2 moving parts - the patented turbine and bearings. The result is low heat and great durability. Automatic loading from your CNC Magazine for complete integration of constant high speed in your programs.
