The AUTOGRIP 3DE series is a high-precision, pull-back power chuck engineered specifically for internal diameter (ID) gripping. During clamping, the jaws expand radially while simultaneously performing an axial pull-down action. This draws the workpiece firmly against the chuck's locating/base surface, completely eliminating the common issue of workpiece lift. Combined with its fully sealed structure, the 3DE series delivers unmatched machining stability, repeatability, and extended tool life.
- Simultaneous Radial Clamping & Axial Pull-down: The unique mechanism pulls the workpiece backward while clamping, ensuring perfect flush seating against the base surface and preventing any workpiece lifting.
- High Precision & Extreme Stability: Offers excellent rigidity and superior repeatability, making it ideal for the tight tolerances required in final finishing operations of automotive and high-precision mechanical parts.
- Fully Sealed Design: Features an enclosed internal structure that allows long-term lubrication while preventing the entry of coolant, chips, dust, and foreign particles, drastically reducing maintenance frequency.
- Airtight Pressure Detection (Optional): Can be equipped with an air-sensing port to verify that the workpiece is perfectly seated against the base, enhancing safety and yield rates in automated production lines.
