ISO/NP 26622-3

Modular taper interface with ball track system — Part 3: Dimensions of shanks, four locking elements ISO/NP 26622-3

Scope

This part of ISO 26622 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, with details
of the coolant-sealing O-ring being given 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.
