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).
