11、g conditions 3 DIN ISO 3442-2:2010-08 1 Scope This part of ISO 3442 specifies the sizes for interchangeability of self-centring, power-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 tol
12、erances which apply to these tests. 2 Normative references The following referenced documents are indispensable for the application of this document.

13、 applies. ISO 230-1:1996, Test code for machine tools Part 1: Geometric accuracy 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
14、of ISO 3442 deals only with the verification of the rotational accuracy of 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.
15、The main purpose of these tests is to allow either top jaw mounting compatible 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 Thi
16、s part of ISO 3442 specifies only one accuracy class. For information, it should be noted that power-operated chucks can be provided, if necessary, with specially adjusted base or master jaws which are not interchangeable with other base or master jaws. In such cases, the chucks shall be marked. Mac
