9、ide 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 right to be represented on th
10、at 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. International Standards are drafted in
11、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 member bodies for voting. Publication as an International Standard r
12、equires 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 identifying any or all such patent rights. ISO 6753-1 was prepared by Tec
13、hnical Committee ISO/TC 29, Small tools, Subcommittee SC 8, Tools for pressing and moulding. This second edition cancels and replaces the first edition (ISO 6753:1:1994), Clause 2 of which has been technically revised. ISO 6753 consists of the following parts, under the general title Tools for press
14、ing and moulding Machined plates: Part 1: Machined plates for press tools Part 2: Machined plates for moulds BS ISO 6753-1:2005blank1Tools for pressing and moulding Machined plates Part 1: Machined plates for press tools 1 Scope This part of ISO 6753 specifies dimensions and tolerances, in millimetr
15、es, of machined plates for press tools. It gives guidance relative to materials and hardness and specifies the designation of machined plates in accordance with this part of ISO 6753. 2 Dimensions See Figure 1 and Table 1. 3 Material and corresponding hardness The material and hardness are left to t
16、he manufacturers discretion. 4 Designation A machined plate for press tools in accordance with this part of ISO 6753 shall be designated as follows: a) “Machined plate”; b) reference to this part of ISO 6753, i.e. ISO 6753-1; c) its edge machining process (oxygen cut, water-jet cut, etc.: 1; milled:
17、 2); d) the grade of its thickness tolerance (1 for normal precision plates; 2 for high precision plates); e) its length a, in millimetres; f) its width b, in millimetres; g) its thickness t, in millimetres. EXAMPLE A normal precision-machined plate with oxygen-cut edges (1), with length a = 160 mm,
18、 width b = 80 mm and thickness t = 20 mm is designated as follows: Machined plate ISO 6753-1 1 - 1 - 160 80 20 BS ISO 6753-1:20052 Values of surface roughness in micrometres NOTE These values of surface roughness apply only to plates with milled edges.
