The work of preparing In

9、ternational 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 that committee. International organizations, governmental and non-governmental, in liaison

10、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 accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of techn

11、ical 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 requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn

12、 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 3442-1 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work holding spindles and c

13、hucks. Together with ISO 3442-2 and ISO 3442-3, this first edition of ISO 3442-1 cancels and replaces ISO 3442:1991 and ISO 9401:1991. ISO/TC 39/SC 8 decided to split ISO 3442:1991 into three parts, at the same time incorporating ISO 9401:1991. As soon as all three parts of ISO 3442 are published, I

14、SO 3442:1991 and ISO 9401:1991 will be withdrawn. ISO 3442 consists of the following parts, under the general title Machine tools Dimensions and geometric tests for self-centring chucks with two-piece jaws: Part 1: Manually operated chucks with tongue and groove type jaws Part 2: Power-operated chuc

15、ks with tongue and groove type jaws Part 3: Power-operated chucks with serrated jaws BS ISO 3442-1:20051Machine tools Dimensions and geometric tests for self-centring chucks with two-piece jaws Part 1: Manually operated chucks with tongue and groove type jaws 1 Scope This part of ISO 3442 specifies

16、the sizes for interchangeability of self-centring, manually operated chucks with two-piece jaws (tongue and groove type) and describes, by reference to ISO 230-1, the geometric tests for such chucks. It also specifies the tolerances which apply to these tests. 2 Normative references The following re

17、ferenced documents are indispensable 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. ISO 230-1:1996, Test code for machine tools Part 1: Geometric acc

18、uracy of machines operating under no-load or finishing conditions 3 Preliminary remarks 3.1 Measurement units All dimensions and tolerances in this part of ISO 3442 are expressed in millimetres. 3.2 Geometric tests This part of ISO 3442 deals only with the verification of the rotational accuracy of

19、the chuck and the positioning of the assembling elements of the top jaws. It does not apply to other dynamic considerations, such as measurement of lack of balance during rotation, balancing or measurement of gripping power. The main purpose of these tests is to allow either top jaw mounting compati

20、ble with the machining accuracy of the chuck or precise setting for top jaws on the chuck after carrying out preliminary centring, straightening or locking operations on a jig separate from the machine. 4 Accuracy classes This part of ISO 3442 specifies only one accuracy class.
