11、reserved Foreword ISO (the International Organization for Standardization) 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
12、which a technical committee has been established has the right 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 al
13、l matters of electrotechnical standardization. International Standards are drafted in 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
14、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 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 res
15、ponsible for identifying any or all such patent rights. ISO 3089 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work holding spindles and chucks. This third edition cancels and replaces the second edition (ISO 3089:1991), which has been technically revised. In parti
16、cular, the tables and figures have been modified.

17、,- INTERNATIONAL STANDARD ISO 3089:2005(E) ISO 2005 All rights reserved 1 Machine tools Test conditions for self-centring, manually-operated chucks with one-piece jaws 1 Scope This International Standard specifies, with reference to ISO 230-1, the geometric tests and corresponding tolerances for sel
18、f-centring, manually-operated chucks for machine tools with more than two jaws. This type of chuck has jaws known as “one-piece hard jaws”, the relatively large stroke of which allows quick adaptation to the most varied sizes of workpieces without dismounting. This International Standard deals only
19、with the inspections of rotational accuracy of the chuck, the straightening and the centring of workpieces. It is not applicable to other dynamic quantities, such as measurement of counterbalancing or measurements gripping powers. 2 Normative references The following referenced documents are indispe
20、nsable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、der no- load or finishing conditions 3 Preliminary remarks All dimensions and tolerances in this International Standard are expressed in millimetres. 4 Accuracy classes Unlike the previous edition, this International Standard specifies only one accuracy class. 5 Geometric tests 5.1 Master pinion Tig
22、htening of the chuck on the test mandrels (test G3) or on the test rings (test G4 to G7) shall be carried out using the master pinion only. The master pinion is a pinion nominated as the reference pinion. 5.2 Input torque For geometric tests, the input torque shall be the same approximately 67 % of
23、maximum input torque as specified by the manufacturer.

The accuracy of test mandrels used shall be as specified in ISO 230-1:1996, A.3,
25、 for test mandrels of similar diameters. 5.4 Test rings 5.4.1 General Test rings/discs shall be manufactured from solid steel and hardened to avoid damage to the active surfaces due to the gripping force of the chuck. In order to minimize the effects of possible distortions of the test ring, it is r
26、ecommended that readings be taken next to the jaws. 5.4.2 Accuracy of the test rings for external jaws The accuracy of test rings/discs for external jaws should satisfy the values listed in Table 1.

28、ince all the geometric tests to be carried out involve the chuck rotation, the chuck should be mounted on a test spindle either directly or by means of a face plate. The radial run-out on the outside diameter of the test spindle or face plate and the camming at any point on its face shall have been
29、previously checked as described by G01 and G02.

The mandrels shall be of different diameters. The sizes of test mandrel diameters to be used shall be proportionate to the scroll pitch so
42、 that various angular scroll positions differ from one test mandrel to another through an arc subtending an angle of approximately 90. The sizes of test mandrel diameters shall be smaller than the diameter at which the jaws are bored. The contact of each jaw on the test mandrels shall be made grippi
43、ng along the centre line of each jaw, it being understood that any increase in the number of contact points or in their width would upset the centring and make the test difficult to carry out. Test G3 shall be repeated not less than three times for each test mandrel to check the repeatability of gri
44、pping; each measured deviation shall fall within the quoted full indicator movement figure. In order to ensure the maximum stability of grip of the jaws on the test mandrels, the test mandrel diameter shall never be larger than the bore diameter of the chuck.
