14、andardization) 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 committee has been established has the rig
15、ht 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 electrotechnical standardization. Draft Interna
16、tional 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. International Standard ISO 3364 was prepared by Technical Committee ISO/TC 29, Small t
17、ools, Subcommittee SC 9, Tools with cutting edges made of hard cutting materials. This third edition cancels and replaces the second edition (ISO 3364:1985), to which subclause 7.5 has been added and Annex A and Annex C have been completed. Annex A, Annex B and Annex C form an integral part of this
18、International Standard. Annex D is for information only. Descriptors: Tools, cutting tools, carbide tools, inserts, dimensions, designation, marking.

These inserts are
20、 primarily intended to be mounted by top and hole clamping or by hole alone on turning and boring tools. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edit
21、ions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently
22、 valid International Standards. ISO 513:1991, Application of hard cutting materials for machining by chip removal Designation of the main groups of chip removal and groups of application. ISO 1832:1991, Indexable inserts for cutting tools Designation. 3 Types of insert The types of indexable hardmet
23、al (carbide) insert specified in this International Standard are the following: TN: triangular inserts, with 0 normal clearance; SN: square inserts, with 0 normal clearance; CN: rhombic inserts, with 0 normal clearance and 80 included angle; DN: rhombic inserts, with 0 normal clearance and 55 includ
24、ed angle; WN: hexagonal (trigon) inserts, with 0 normal clearance and 80 included angle. Inserts covered by in this International Standard are standardized with chip breakers on both faces, with chip breakers on one face only and with no chip breakers at all. At present, neither the shape nor the di
25、mensions of chip breakers are standardized. Thus, if necessary, special features have to be explained by means of a diagram or additional specifications. Table C.1 gives the range of sizes for these inserts. 4 Interchangeability 4.1 Tolerances Indexable hardmetal (carbide) inserts specified in this
26、International Standard are provided in tolerance class M in accordance with ISO 1832. The values of the tolerances in accordance with ISO 1832 are given in Annex A. Other tolerances are given, either in Table 1 for hole dimensions, or in Table 2 to Table 6 for insert dimensions. 4.2 Thickness, s, of
27、 inserts with chip breakers The thickness, s, of inserts with chip breakers is defined as the distance between the cutting edge at the corner and the opposing supporting surface of the insert; see Figure 1 a) and Figure 1 b) for inserts with chip breakers on one face only and Figure 1 c) for inserts
28、 with chip breakers on both faces.

29、to the diameter d of the inscribed circle of the insert according to Table 1. Table 1 Fixing hole 5 Designation and marking 5.1 Designation The designation of the indexable hardmetal (carbide) inserts complying with this International Standard shall conform to ISO 1832. In addition to this designati
30、on, one or both of the following may be indicated: the symbol of the group of application, according to ISO 513; the commercial designation of the hardmetal (carbide) grade. 5.2 Marking The following symbols, at least, shall be marked on the insert itself (except when this would be difficult on the
31、smaller inserts): symbol of the group of application, or commercial designation of the hardmetal (carbide) grade (or both, if possible, on large inserts). 6 Measurement Annex B indicates the methods of measuring the dimension m of the indexable inserts covered by this International Standard.
