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.
