625JS

625 CNC Spindle Series

The versatile and reliable 625JS (3/4” / 20 mm straight shank) delivers governed constant high speeds under load – 30,000 to 65,000 RPM, < 0.55 HP (0.41 kW). Speed up your cycle times and reduce tool breakage with this compact series. Ideal for mold making, milling and finishing with small tools up to 1/4” / 6mm capacity. With only 2 moving parts and air circulation over the bearings the 625JS has no heat or thermal expansion along with 2 micron ultra precision. Get the reliability of direct drive milling with no duty cycle. Selectable rear or side air feed.
