BS ISO 26622-1:2017 pdf download – Modular taper interface with ball track system Part 1: Dimensions and designation of shanks
This document specifies the dimensions for modular taper interface with ball track system: tapered shanks for automatic and manual tool exchange to be applied on machine tools (e.g. lathe machines, drilling machines, milling machines and turn/milling machine centres). A range of shank sizes is specified and details of the coolant-sealing O-ring are specified in Annex A.
The shank incorporates a flange with a groove to enable automatic tool exchange. The tools can also be exchanged manually. The clamping of the shank can be realized by the use of locking balls of a standard size and by a variety of mechanisms.
The torque is transmitted at the tail end of the shank by friction, locking elements and keys.
