ER20 Elastic Collet (CNC Machine Chuck).
Model: Elastic Collet 20 (ER20); Maximum clamping diameter: approx. 20mm;
Appearance: Metal, cylindrical, with evenly distributed elastic grooves on the surface (shown by black lines), and a "3/4" marking on the side (possibly a specification parameter or production number).
Core Uses and Features
Uses: Used in CNC machine tools, CNC engraving machines, etc., to clamp milling cutters, drill bits, and other cutting tools. The elastic grooves allow for rapid clamping and positioning.
Features: High precision (clamping accuracy up to 0.008mm), elastic design adaptable to cutting tools of different diameters, metal material ensures strength and wear resistance.
Applications: Widely used in CNC engraving machines, CNC machining centers, milling machines, etc., suitable for wood carving, metal processing, mold making, and other scenarios, especially suitable for precision machining where high tool positioning accuracy is required.
Selection and Usage Recommendations
Model Matching: Select according to the maximum diameter of the cutting tool (e.g., ER20 corresponds to ≤20mm). Common models also include ER16, ER25, and ER32.
Precision Requirements: For high-precision machining (such as precision mold engraving), it is recommended to choose products marked "high precision" or "one-micron precision".
Maintenance Notes: Regularly clean debris from the elastic groove and avoid oil or corrosive substances affecting the elastic performance.
