BS ISO 26623-1. Polygonal taper interface with flange contact surface Part 1. Dimensions and designation of shanks
|Standard number:||19/30383674 DC|
- 25.060.20 Dividing and tool-workpiece holding devices
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).
