660JS

660 CNC Spindle Series

The 660JS (3/4” / 20 mm straight shank) is ideal for heavier duty applications and milling hard materials in corners. The 660 features a higher governed constant speed at 50,000 RPM and even higher power at 0.94 HP (0.7 kW). Our proprietary governor-controlled turbine maintains rated high speed, optimizing tool performance and life. 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 our governor adjusting CFM airflow to the minimum required to maintain high speed. With 2µ precision in its ER11 Ultra-Precision collet the 660 is also very precise. Selectable rear or side air feed on each spindle. Automatic loading from the magazine on all machines.
