Polygonal taper interface with flange contact surface — Part 1: Dimensions and designation of shanks (ISO 26623-1:2020, IDT) (Swedish Standard)
This document specifies dimensions for polygonal taper interfaces with flange contact surface — polygon shanks for automatic and manual tool exchange to be applied on machine tools (e. g. turning machines, drilling machines, milling machines and turn/milling centres as well as grinding machines). A range of shank sizes is specified. These shanks incorporate a grooved flange to enable automatic tool exchange. The clamping can be realized by a circular groove using clamping segments or internal screw threads using centre-bolts. The torque is transmitted by form lock (polygon).
