|ICS Code (Dividing and tool-workpiece holding devices):||25.060.20|
This part of ISO 26623 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).
