Technical Information Hydraulic Chucks General Design (continued) Application Hydraulic expansion chucks work best when clamping these style shanks: • Shanks to DIN-6535 — forms HA, HB, and HE. • Shanks to DIN-1835 — forms A and B (with shank tolerance h6 and Ra minimum of 0,3 μm). 0,003mm • Forms HA and A — plain cylindrical shank, 6–32mm diameter. (.0001") • Forms HB and B — Whistle Notch™ shank, 6–20mm maximum diameter. D h6 • Form HE — Whistle Notch shank, 6–20mm maximum diameter. (WIDIA™ suggests the use of a reducer collet). • Inch straight shanks: 2.5 x D - 1/4–5/8" (.0004 under nominal diameter maximum). max 50mm - 3/4–1-1/4" (.0005 under nominal diameter maximum). (2") Slim Line Design Weldon® shanks with a maximum diameter of 20mm (3/4") can be gripped without reducer collets. However, WIDIA recommends using reducer collets for all flatted shanks. Highest accuracy is obtained with plain, cylindrical shanks. 0,006mm (.0002") D h6 2.5 x D max 50mm (2") Using a sleeve gives higher grip torque: Formula: sleeve bore x chuck torque = assembled torque chuck bore Example: 12mm (sleeve bore) x 220 Nm = 132 Nm 20mm (chuck bore) While chart shows for a 12mm Hydraulic Chuck = 70 Nm approx. 2x grip advantage K62 WWW.WIDIA.COM Technical Information
