The work of preparing International Standards is normally carri
4、ed out through IS0 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work.
5、 Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting.
6、 International Standard IS0 7959 was prepared by Technical Committee ISO/TC 39, Machine tools. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise sta

8、cense from IHS -,-,- INTERNATIONAL STANDARD IS0 7959 : 1987 (E) Woodworking machines - Double edging precision circular sawing machines - Nomenclature and acceptance conditions 1 Scope and field of application This International Standard specifies the nomenclature appropriate to each part of the mac
9、hine and, with reference to IS0 230-1, the geometrical and practical tests for double edging precision circular sawing machines, and gives the cor- responding permissible deviations which apply to machines of general purpose use and normal accuracy. NOTE - In addition to terms used in the three offi
10、cial IS0 languages (English, French and Russian), this International Standard gives the equivalent terms in the German, Spanish, Italian and Swedish languages in an annex; these have been included at the request of Technical Committee ISOITC 39 and are published under the responsi- bility of the mem
11、ber bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy (UNI) and Sweden (SISJ. However, onfv the terms given in the official languages can be considered as ISO-terms. This International Standard deals only with the verification of the accuracy of the machine. It does not apply to the testing of t
12、he running of the machine (vibrations, abnormal noises, stick- slip motion of the components, etc.), nor to its characteristics (speeds, feeds, etc.) which should generally be checked before the accuracy is tested. This International Standard applies to those machines designated by the number 12.132
13、.34 in IS0 7994. The annex does not form an integral part of this International Standard. 2 References IS0 230-1, Acceptance code for machine tools - Part 1: Geometric accuracy of machines operating under no-load or finishing conditions.

14、oodworking machines and auxiliary machines for wood- working. 3 Preliminary remarks 3.1 In this International Standard all dimensions and permiss- ible deviations are expressed in millimetres. 3.2 To apply this International Standard, reference should be made to IS0 230-1, especially for installatio
15、n of the machine before testing, the warming up of the main spindle and other moving parts, and the description of the measuring methods. The measuring instruments shall not permit measurement errors over l/3 of the checked tolerances. 3.3 The sequence in which the geometrical tests are given is rel
16、ated to the sub-assemblies of the machine, and this in no way defines the practical order of testing. In order to make mounting of instruments and -gauging easier, tests may be applied in any order. 3.4 When inspecting a machine, it is not always possible or necessary to carry out all the tests give
17、n in this International Standard. 3.5 It is up to the user to choose, in agreement with the manufacturer, those tests relating to the properties which are of interest to him, but these tests shall be clearly stated when ordering a machine. 3.6 A movement is longitudinal when it takes place in the wo
18、rking direction of the piece. 3.7 When establishing the tolerance for a measuring range different from that given in this International Standard (see subclause 2.311 in IS0 230-I), it should be taken into con- sideration that the minimum value of the tolerance is 0,Ol mm.
