DIN Standards Committee Tools and Clamping Devices

Overview

Part 5 of the standard series DIN 69893 has been prepared by the Tools and Clamping Devices Standards Committee (FWS), 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) and on the elaborations of the Spindelarbeitskreis (Spindle Working Group) at the Institut für Produktionstechnik und Spanende Werkzeugmaschinen (Institute for Production Engineering and Metal Cutting Machine Tools) of the Technical University Darmstadt. DIN 69893-5 specifies the dimensions for hollow taper shanks (HSK) with flat contact surface, type E, which are used on high speed main spindles of machine tools (for example, drilling, milling and grinding machines). The torque is frictionally transferred. Type E is automatically changeable by means of a gripping groove and contains the connection dimensions for a coolant pipe in accordance with DIN 69895. With respect to version DIN 69893-5:2006-11, HSK-E size 20 has been incorporated in Table 1 and Table 2 and an informative clamping force value for HSK-E size 20 has been supplemented in Table A.1.
