The work of pre
10、paring 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-governmental, in
11、 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 3. The main task
12、 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. Attention
13、 is drawn to the possibility that some of the elements of this part of ISO 5414 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5414-2 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 2, Drills, ream
14、ers, milling cutters and milling machine accessories. This second edition cancels and replaces the first edition (ISO 5414-2:1982), which has been technically revised (in particular by the addition of shanks with diameters 14 mm and 18 mm, and of chucks with 7/24 taper shanks for automatic changers)
15、. ISO 5414 consists of the following parts, under the general title Tool chucks (end mill holders) with clamp screws for flatted cylindrical shank tools: Part 1: Dimensions of the driving system of tool shanks Part 2: Connecting dimensions of chucks and designation BSISO54142:2002iiiINTENRATIONAL TS

17、ews for tools with flatted cylindrical shanks in accordance with ISO 3338-2. It also specifies the designations of these chucks. Two types of connection are defined: chucks with 7/24 taper shanks in accordance with ISO 297 for manual changers and with ISO 7388-1 for automatic changers, for tool shan
18、ks with either single flat or a double flat for manual and automatic changers; NOTE 1 This part of ISO 5414 specifies the dimensions of tool chucks with 7/24 taper shanks No. 30 for automatic changers although these are not standardized. chucks with Morse taper shanks in accordance with ISO 296 and
19、ISO 5413 for tool shanks with a single flat only. NOTE 2 The dimensions of the driving system of the tool shanks are dealt with in ISO 5414-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO
20、5414. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 5414 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
