650JS

650 CNC Spindle Series

The 650JS (3/4” / 20mm Straight Shank) delivers governed constant high speeds under load – 25,000 to 40,000 rpm, < 0.88 hp (0.66 kW). Robust and reliable, with double front ceramic bearings, the 650 Series is ideal for heavier duty applications and milling hard materials in corners. The governor-controlled turbine maintains rated high speed, optimizing tool performance and life. Effective in all materials, including tool steel, titanium, and ceramic. Ultra-low vibration and no heat in 24/7 operation. Selectable rear or side air feed on each spindle. Automatic Loading from the magazine on all machines.
