A Hydraulic Rotary Collet Chuck is a power-operated rotary workholding system actuated by hydraulic pressure through a rotary union, providing strong and consistent clamping during continuous rotation. It offers excellent concentricity, rigidity, and stability under heavy cutting loads, making it ideal for CNC lathes, turning centers, rotary tables, trunnions, and 4-axis/5-axis machining centers using OD or ID collet systems.
Hydraulic Rotary Collet Chuck is a power-operated rotary workholding system that uses hydraulic pressure via a rotary union to actuate precision collets during continuous rotation. It delivers much higher and more consistent clamping force than pneumatic systems, ensuring excellent concentricity, rigidity, and stability—even under heavy cutting loads.
Ideal for CNC lathes, turning centers, rotary tables, trunnions, and 4-axis/5-axis machining centers, this chuck supports OD collets (pull-back) and ID expanding collets as per application.
