ER collet is a type of collet that is commonly used in milling chucks. It is a cylindrical metal sleeve with a tapered inner surface that expands when tightened, gripping the tool or workpiece securely. ER collets are designed to hold round shank tools, such as end mills, drills, and reamers, in milling chucks.
The ER collet system is widely used in milling appliCATEEions due to its versatility and accuracy. It allows for quick tool changes and provides good concentricity, ensuring precise machining. ER collets come in various sizes, designated by a number such as ER16, ER32, or ER40, which indiCATEEes the maximum tool diameter they can hold.
To use an ER collet in a milling chuck, the collet is inserted into the chuck and tightened using a collet nut. The tool or workpiece is then inserted into the collet and secured by tightening the nut further. This creates a strong grip on the tool, preventing slippage during machining operations.
Overall, ER collets are a popular choice for milling chucks due to their reliability, ease of use, and ability to hold a wide range of tool sizes.
