660CAT50
the tools of a new generation™
The 660CAT50 is ideal for heavier duty applications and milling hard materials in corners. The 660 features higher governed constant speed at 50,000 RPM and even higher power at 0.94 HP (0.7 kW). Air Turbine Spindles® direct drive turbine operates with very low vibration and no heat in 24/7 operation. As a result the 660 mills faster in all materials, including tool steel, titanium and ceramics reducing cycle times dramatically.
For long life milling in hard materials this robust 660 series is equipped with quadruple air cooled angular contact bearings. Economical consumption of air results from the governor adjusting CFM air flow to the minimum required to maintain high speed.
With 2µ precision in its ER11 UP collet the 660 is also very precise. Select rear or side air feed on each spindle.
Automatically Load and Unload
Automatic loading available using through spindle air supply with the patented collar and block TMA assembly, or tool change without the TMA on certain machines that have an air blast line or coolant channel supplying a sufficient air flow volume.

Tool Changer Mounting Assembly - 650, 650X & 660 Series
Automatically load the 650 and 660 series of Air Turbine Spindles® in your CNC machine with the patented wrap-around Tool Changer Mounting Assembly (TMA). The TMA block remains on the CNC spindle for normal tool changes, and does not interfere with the main spindle. This collar system allows CNC tool changers to automatically load/unload your Air Turbine Spindle®.
Drilling of mounting block holes required for universal blocks.
The Tool Changer Mounting Assembly is a factory installation
When purchasing a TMA for an already-owned spindle you must send your current spindle to us for the TMA to be installed.
