Why Rotary Unions Fail in CNC Machines: Causes, Solutions, and How to Choose the Right CNC Rotary Union
Modern CNC machining centers rely heavily on stable coolant delivery systems to maintain machining precision, extend tool life, and support continuous high-speed operation. At the center of this system is the CNC rotary union — a critical component that transfers coolant, air, or hydraulic media from stationary piping to a rotating spindle. However, rotary union…
