machining center rotary joints
Overview
The machining center rotating joint (also called rotary union) is a precision fluid transmission component installed on the spindle of CNC machining centers. It realizes continuous delivery of hydraulic oil from the stationary pipeline to the rotating spindle without hose twisting, which is essential for spindle hydraulic power and clamping control.
