The responsible German body involve
6、d in its preparation was the Normenausschuss Werkzeuge und Spannzeuge (Tools and Clamping Devices Standards Committee), Working Committee NA 121-02-07 AA Drehmaschinenspannzeuge und Zubehr. Following a proposal of the German Working Committee, ISO 702-1 has been editorially harmonized with ISO 702-2
7、, ISO 702-3 and ISO 702-4. All four ISO Standards have been adopted as DIN ISO Standards and published as a series. This second edition cancels and replaces the first edition (ISO 702-3:1975), which has been technically revised. DIN ISO 702 consists of the following parts, under the general title Ma

Spindle nose types A, B and C pre
9、viously specified in DIN 55028 have been replaced and are now dealt with in DIN ISO 702-1 (types A and B) and DIN ISO 702-3 (type C). With the publication of the DIN ISO 702 series of standards, DIN 55026, DIN 55027, DIN 55028 and DIN 55029 have been withdrawn. Attention is drawn to the possibility

11、completely revised and brought into line with the current state of technology. b) Drawings and dimensioning have been revised and brought into line with the current rules of presentation. c) The tables have been revised accordingly. d) The type C spindle nose from DIN 55028 has been replaced.
