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") 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 to be applied on machine tools (such as turning machines, drilling machines, milling machines and grinding machines). 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. Type B is automatically exchangeable by means of drive key notches and indexing grooves. Manual actuation of the clamping mechanism can be performed by means of a bore in the taper shank.
