The w
7、ork of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-govern
8、mental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
9、 main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
10、 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 identifying any or all such patent rights. ISO 702-2 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work hold
11、ing spindles and chucks. This second edition cancels and replaces the first edition (ISO 702-2:1975), of which all the clauses, tables and figures have been technically revised. ISO 702 consists of the following parts, under the general title Machine tools Connecting dimensions of spindle noses and
12、work holding chucks: Part 1: Conical connection Part 2: Camlock type Part 3: Bayonet type Part 4: Cylindrical connection BS ISO 702-2:2007 1 Machine tools Connecting dimensions of spindle noses and work holding chucks Part 2: Camlock type 1 Scope This part of ISO 702 specifies the sizes for intercha
13、ngeability of cylindrical spindle noses and corresponding connecting faces of face plates or work holding chucks. NOTE The “conical connection”, “bayonet type” and “cylindrical connection” are dealt with in ISO 702-1, ISO 702-3 and ISO 702-4, respectively. 2 Interchangeability In this part of ISO 70
14、2, all the dimensions and tolerances are expressed in millimetres. Although internal mounting components and assembly screws are not respectively interchangeable, as they may conform with either the metric or inch series, there is complete interchangeability between metric spindle noses and face pla
15、tes in inches and vice versa. BS ISO 702-2:20072 3 Sizes for interchangeability 3.1 Spindle noses Key 1 size No. 3 2 size No. 4 3 size Nos. 5 to 20 aReference line.
