The ER collet chuck with HSK63A interface is a high-precision tool holder designed to meet the demands of professionals and specialized operators in mechanical engineering, CNC machining and high-performance milling. It is intended for clamping cylindrical shank tools by means of collets in compliance with DIN ISO 15488-B, ensuring maximum compatibility and versatility in a wide range of applications.

Technical Data:

The ER system stands out for its wide clamping range, which allows secure holding of tools with different shank tolerances, simplifying tool management and reducing the need for dedicated holders. The HSK63A interface guarantees extremely rigid and precise coupling with the machine spindle, providing stability and repeatability even in high-speed machining, where tight geometric tolerances and high surface quality are required.

A key feature is the G2.5 balance grade, which ensures optimal performance even at high rotational speeds, minimizing vibrations and wear. This chuck is capable of reaching a maximum rotational speed of 25,000 rpm, making it particularly suitable for High Speed Cutting (HSC) operations and for applications that require extreme reliability of the clamping system.

The included clamping nut allows uniform and secure tightening of the collet, improving overall stability and making tool mounting and replacement easier. The combination of the HSK63A body, ER collets and clamping nut provides an efficient, precise and durable system, capable of ensuring consistent performance both in workshops and in advanced machining centers.
