Amendments This standard differs from DIN 55026:1980-03 and DIN 55028:1980-03 as follows: a) The standard has been completely revised and brought into
11、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.

12、O 702 specifies the sizes for interchangeability of conical spindle noses and corresponding connecting faces of face plates or work holding chucks. NOTE The “camlock type”, “bayonet type” and “cylindrical connection” are specified in ISO 702-2, ISO 702-3 and ISO 702-4, respectively. 2 Interchangeabi
13、lity In this part of ISO 702, all dimensions and tolerances are expressed in millimetres. Although there are differences in the values of dimensions and assembly screws in metric and inch series, the connecting dimensions in Tables 1 and 2 allow for interchangeability between metric- and inch-based
14、chucks (see also footnote “a” in Table 2). 3 Sizes for interchangeability 3.1 Spindle noses See Figure 1 and Table 1. Type A1: Two bolt circles of diameter d2and d3; Type A2: One outer bolt circle of diameter d3(Type A2 for Nos. 3 and 4; types A1 and A2 for Nos. 5 to 28). DIN ISO 702-1:2010-04 4 Mac
