The ER collet chuck with HSK40E taper is a high-precision solution for clamping cylindrical shank tools, in full compliance with DIN ISO 15488 standards. Thanks to the versatility of the ER system, it allows clamping of shanks with different tolerances, ensuring a wide range of applications and great operational flexibility. When precision collets are used, accuracy levels of up to 3 microns can be achieved, guaranteeing outstanding performance in machining operations where dimensional precision and surface quality are critical.

Technical Data:

The HSK40E interface is designed to ensure optimal coupling with the machine tool, combining high structural rigidity with dynamic stability even under demanding working conditions. This collet chuck is balanced to G2.5 at speeds up to 25,000 rpm or with Umax below 1 gmm, making it suitable for high-speed cutting (HSC) applications where vibration reduction is essential to preserve both tool life and workpiece integrity.

The run-out accuracy of less than 0.003 mm at 2.5 times the tool diameter highlights the outstanding manufacturing quality of this chuck, ensuring optimal concentricity during cutting operations and greater process reliability. The supplied clamping nut guarantees a uniform and secure grip on the tool, while also facilitating quick and safe tool changes.

This ER collet chuck with HSK40E taper is widely used in sectors such as aerospace, automotive, mold making, and precision engineering, where stability, accuracy, and repeatability of clamping are fundamental to achieving the highest product quality and production efficiency.
