Organization: ISO
Publication Date: 1 November 2020
Status: active
Page Count: 20
ICS Code (Dividing and tool-workpiece holding devices): 25.060.20
scope:

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).
