ISO 26623‑1 is part one of the multi-series standard that 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).
ISO 26623‑1 helps you in designing and manufacturing machines with precision.
ISO 26623‑1 on polygonal taper interface with flange contact-surface dimensions and designation of shanks is useful for:
ISO 26623‑1 specifies dimensions for polygonal taper interfaces with flange contact surface. This will help you in designing and manufacturing machines with precision.
ISO 26623‑1 provides you guidance for design, clamping forces and designation.
BS ISO 26623‑1:2020 is the third edition that cancels and replaces the second edition ISO 26623‑1:2014, which has been technically revised.
The main changes compared to the previous edition are as follows:
