3-jaw draw down power chuck

Draw down power chuck feature of radial clamping will lead to almost no work piece uplifting displacement; for machining casting and forging part:
  • For the clampped work-piece is appressed to the surtace, chucks are suitable for heavy machining.
  • Chuck Actutors with cylindrical structure are durable and ensures high clamping repeatability.
  • Accurate self-centering and pull back features are adequate or precise length control machining requirements.
