Industry Solutions Machine Tool
We provide fluid sealing solutions for machine tool applications.
Designed for high pressure and high speed service, DSTI’s proven rotary unions (joints) meet the demands of today’s advanced machine tool workholding and lathe chuck applications. Single and multiple-flow passage designs provide a flexible and cost-effective solution for reliable sealing and transfer of oil, air, coolant, and other media types.
Fluid Sealing Solutions
Fluid Sealing Solutions Rotary Table & Workholding Systems
Reliable supply and flow control of hydraulics and pneumatics is critical for clamping operations. DSTI offers high-precision rotary union solutions for continuous flow and rotary timing valve solutions for controlling flow to meet the exact fluid, operating pressure, speed, and the space requirements of each unique workholding application.
Fluid Sealing Solutions Hydraulic & Pneumatic Lathe Chucks
DSTI’s fluid rotary unions for high-speed lathe machining provide high performance hydraulic and pneumatic solutions critical for reliable workpiece clamp force. Specialized designs for lathe chuck applications prevent crosstalk between flow channels delivering dependability with both simultaneous oil, air and other media type service.
