11、ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical
12、committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of elect
13、rotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the
14、member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ident
15、ifying any or all such patent rights. ISO 702-1 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work holding spindles and chucks. This third edition cancels and replaces the second edition (ISO 702-1:2001), Tables 1 and 2 and Figures 1 and 2 of which have been techni
16、cally revised. ISO 702 consists of the following parts, under the general title Machine tools Connecting dimensions of spindle noses and work holding chucks: Part 1: Conical connection Part 2: Camlock type Part 3: Bayonet type Part 4: Cylindrical connection In this corrected version of ISO 702-1:200
17、9, the “” (minus) sign has been deleted from the zero values of tolerance of d1in Table 1 and footnote “c” of Table 2 has been corrected to read “Type A1” and “Type A2”.

18、dimensions of spindle noses and work holding chucks Part 1: Conical connection 1 Scope This part of ISO 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 “cylin
19、drical connection” are specified in ISO 702-2, ISO 702-3 and ISO 702-4, respectively. 2 Interchangeability 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, th
20、e connecting dimensions in Tables 1 and 2 allow for interchangeability between metric- and inch-based 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 o
21、f diameter d3(Type A2 for Nos. 3 and 4; types A1 and A2 for Nos. 5 to 28).
