Description
This product is a high-precision, high-rigidity pull-back collet chuck system specifically engineered for external diameter (OD) clamping applications.
By utilizing a draw-back mechanism, the system generates uniform and stable clamping force, ensuring excellent concentricity and machining stability throughout the process.
Unlike multi-purpose clamping systems, this solution is optimized exclusively for OD clamping. The simplified structure enhances rigidity and consistency, making it ideal for high-precision and high-repeatability production environments.
It is widely used in shaft components, cylindrical parts, and precision turning applications, providing a reliable solution for manufacturers seeking superior machining quality and productivity.
