Stationary Pull Lock Chuck
Pull Lock | 3-JAW
  • Build-in hydraulic cylinder; it can also work with lock valve and be driven by air pressure.
  • Radial clamp and axial pull down at the same time, keep the workpiece attaching close to the base surface of the chuck.
  • Almost no workpiece uplifting displacement.
  • Suitable for drilling, milling and other machines.
  • The body with heat treatment and the organization of cylinder pull-down, and fine boring, which guarantee to the high clamping precision and durableness, it’s suitable for heavy duty machining.
  • Can work together with multi-plate.
  1. Airtight pressure detect function is optional.
