Description

QX series 3-jaw pneumatic hollow power chucks are manufactured from high-strength alloy steel with overall quenching and precision grinding, providing fast and reliable workholding solutions for automated CNC lathe machining.
  1. Pneumatic drive system delivers ultra-fast clamping and unclamping response, significantly improving production efficiency for automated lines.
  2. Large hollow through-hole design allows long bar stock to pass through, perfect for continuous automatic bar feeding production.
  3. 3-jaw self-centering design ensures high centering accuracy ≤0.01mm, delivering stable machining precision.
  4. Compact structure with excellent dynamic balance performance, suitable for high-speed turning operations.
  5. Standard mounting dimensions compatible with most common CNC lathe spindles, easy to install and maintain.
  6. Built-in safety mechanism maintains clamping force even in case of sudden air pressure loss.
