ERSK50P SCHUNK ER25, ER32, ER40 precision collet chuck with SK50 shank DIN ISO 7388-1 AD/AF for clamping tools with cylindrical shank DIN ISO 15488, length of your choise
(Incl. Tax: €260.23)
The SH-ERSK50P SCHUNK precision collet chuck is designed for clamping tools with cylindrical shanks according to DIN ISO 15488. It features an SK50 shank that complies with DIN ISO 7388-1 AD/AF standards, ensuring strong and reliable tool holding during machining operations. The chuck is available in various lengths to accommodate different applications. Its ER25, ER32, and ER40 collet sizes provide versatility for a range of tool diameters, making it suitable for precision tasks in milling, drilling, and other CNC machining processes. The special care taken in manufacturing allows for a maximum concentricity error of less than 3 microns (< 0.003 mm) detected at a distance of 2.5xD. The perfect balance of G2.5 safely allows spindle rotation up to 25,000 rpm or with a maximum residual imbalance of Umax<1gmm. Due to its robust and precise construction, it ensures high reliability and high-performance during use.
