3-jaw draw down power chuck
Draw down power chuck feature of radial clamping prevents workpiece displacement caused by uplifting; for machining casting and forging part:
Draw down power chuck feature of radial clamping prevents workpiece displacement caused by uplifting; 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.
