Product Name: High-Pressure Through-Spindle Coolant Rotary Union
Description:A Rotary Union (also known as a rotary joint or swivel) is a precision mechanical device designed to transfer high-pressure coolant from a stationary inlet source to a rotating spindle or tool holder on a Vertical Machining Center (VMC) . It is the critical component enabling Through-Spindle Coolant (TSC) systems.
Key Functions & Advantages:
High-Pressure Sealing: Engineered to withstand extreme internal coolant pressures (typically ranging from 300 psi / 20 bar up to 1500+ psi / 100 bar), ensuring a leak-free seal even during high-speed rotation.
Deep Hole Drilling: Facilitates efficient chip evacuation during deep-hole drilling operations by flushing chips out through the flutes of the drill.
Improved Tool Life: Delivers coolant directly to the cutting edge, providing superior lubrication and heat reduction, which significantly extends tool life and improves surface finish.
Reliable Performance: Constructed from wear-resistant materials such as sintered carbide, hardened steel, and corrosion-resistant stainless steel to ensure long service life in harsh machining environments.
Dual Flow Options: Available in single-channel designs (coolant only) or multi-channel designs (coolant, air, or MQL - Minimum Quantity Lubrication).
Application:
Specifically designed for integration into the rear of the spindle housing on Vertical Machining Centers, this rotary union ensures consistent coolant flow for high-speed machining, gun drilling, and high-pressure machining applications.
