CB-Pull Back Collet Chuck
Feature
- High-Rigidity Draw-Back Clamping Design
- Axial Stop Positioning
- Optimized for Short Workpieces
- Excellent Concentricity Performance
- Stable and Consistent Clamping Force
- Quick Collet Change
Description
This is a high-precision draw-back collet chuck specifically developed for short workpiece applications.
The collet is pulled inward by a draw-rod mechanism, simultaneously drawing the workpiece against the internal axial stop, achieving radial clamping and axial positioning at the same time. This design effectively enhances machining stability and repeatability, making it particularly suitable for high-precision and high-efficiency CNC turning operations.
With its rigid structure and strong clamping force, this product significantly reduces vibration and runout during machining, ensuring consistent machining quality.
