Description / Abstract:
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).
