9、ers and Hand Tools Standards Committee and forms part of a series, each Part dealing with an aspect of hardmetal insert tooling. The series implements corresponding International Standards in the development of which the UK has played an active part. This Part of BS 4193 is identical with ISO 3365 “
10、Indexable hardmetal (carbide) inserts with wiper edges, without fixing hole Dimensions” which was revised and published in 1985 by the International Organization for Standardization (ISO) and was prepared by Technical Committee ISO/TC 29, Small tools. It supersedes BS 4193-4 and BS 4193-5, which are
11、 now withdrawn. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to
12、 the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. Th
13、e Technical Committee has reviewed the provisions of ISO 513:1975, referred to in clauses 2 and 5, and has decided that they are acceptable for use in conjunction with this Part of BS 4193. ISO 883:1985, ISO 3364:1985 and ISO 6987-1:1983 are only referred to in clause 2 for information. A British St
14、andard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International StandardCorresponding

24、geability 4.1 Tolerances Indexable hardmetal (carbide) inserts specified in this International Standard are provided in the following tolerance classes in accordance with ISO 1832: a) inserts with 0 and 11 normal clearance (TP, SN and SP): tolerance classes A, C and K, where class C is used mainly f
25、or coated inserts; Licensed Copy: sheffieldun sheffieldun, na, Fri Dec 01 01:15:07 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 4193-15:1986 2 BSI 08-1999 b) inserts with 20 normal clearance (TE and SE): tolerance class C. The values of the tolerances in accordance with ISO 1832 are given in Annex
26、A. Other tolerances are included in the diagrams and tables with the insert dimensions in clause 7. 4.2 Dimensions m Dimension m specified in the tables refers to a theoretically perfect insert. In practice, as the points on which the inserts are located in both manufacture and measuring may be diff
27、erent, the nominal value of dimension m may vary from one manufacturer to another within a range of 0,05 mm. Nevertheless, for inserts of the same manufacturer, dimension m shall comply with the tolerances in accordance with ISO 1832 (see Annex A). 5 Designation and marking 5.1 Designation The desig
28、nation of the indexable hardmetal (carbide) inserts complying with this International Standard shall conform to ISO 1832. In addition to this designation, one or both of the following may be indicated: the symbol of the group of application, in accordance with ISO 513; the commercial designation of
29、the hardmetal (carbide) grade. 5.2 Marking The following symbol, at least, shall be marked on the insert itself (except when this would be difficult on the smaller inserts): symbol of the group of application, or commercial designation of the hardmetal (carbide) grade (or both, if possible, on large
30、 inserts). 6 Measurement Annex B indicates the methods of measuring the dimension m of the indexable inserts covered by this International Standard. 7 Recommended dimensions The choice of the more common dimensions is restricted to the specifications given in Table 1 to Table 12. It is strongly reco
31、mmended that these standard inserts be used wherever possible.

B.1 Triangular inserts Dimension m is checked by reference to the diameter d of a precision roller, where d correspon
47、ds to the nominal diameter of the inscribed circle of the insert. The insert is mounted on a 60 vee-block as shown in Figure 1 and checked by means of a dial gauge which has been zeroed to dimension m by means of a roller with the aid of a gauge block. The dial gauge then gives a direct reading of t
48、he error when applied to the inserts to be measured. The roller has a tolerance of 0,002 mm. B.2 Square inserts Dimension m is checked by reference to the diameter d of a precision roller, where d corresponds to the nominal diameter of the inscribed circle of the insert. The insert is mounted on a 9
