It also specifies the tol

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
