DIN Standards Committee Tools and Clamping Devices

Overview

This standard has been prepared by Working Committee NA 121-02-05 AA "Kupplungen für modulare Werkzeuge" ("Interfaces for modular tools"). The dimensions specified in this standard are in accordance with those given in ISO 12164-1:2001. The International Standard ISO 12164-1 has been prepared by Working Group ISO/TC 29/WG 33 "Hollow tool shank interface" of ISO/TC 29 "Small tools", with the significant participation of German experts of NA 121-02-05 AA and is based on the results of the research project "Untersuchung der Gestaltungsmöglichkeiten für die Schnittstelle Maschine/Werkzeug" ("Examination of the design possibilities for the interface between machine and tool") of the Laboratorium für Werkzeugmaschinen und Betriebslehre der Rheinisch-Westfälischen Technischen Hochschule Aachen (Laboratory for Machine Tools and Production Engineering of the Rhenish-Westphalian Technical University Aachen). This standard specifies the dimensions for hollow taper shanks with flange contact surface (HSK) to be applied on machine tools (such as turning machines, drilling machines, milling machines and grinding machines). A range of shank sizes has been specified. Two shank types were included. Type A incorporated a grooved flange to enable automatic tool exchange. The tools are also manually exchangeable. Type C has no groove in its flange and can only be manually exchanged. For both types, a bore in the taper shank has been provided for manual clamping. The torque is transmitted by friction lock over the conical and mating surface and by form lock via driving slots at the tail end of the flange.
