7、ing Committee NA 121-02-07 AA Drehmaschinenspannzeuge und Zubehr. This third edition cancels and replaces the second edition (ISO 3089:1991), which has been technically revised. DIN ISO 3089:2010-11 partially replaces the test conditions specified in DIN 6386-1:1977-05. Attention is drawn to the pos

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 self-centring, manually-operated ch
12、ucks 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 with the inspections of rotation
13、al 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 indispensable for the application of th

16、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 maximum input torque as specified
17、 by the manufacturer. 4 DIN ISO 3089:2010-11 5.3 Test mandrels The test mandrels shall be manufactured from solid steel and hardened to avoid damage to external surface due to the gripping force of the chuck. The accuracy of test mandrels used shall be as specified in ISO 230-1:1996, A.3, for test m
18、andrels 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 recommended
19、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.

21、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.

References to ISO 230-1 and observations The number of test mandrels to be used is four. The mandrels shall be of different diameters. The sizes of test
30、mandrel diameters to be used shall be proportionate to the scroll pitch so 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 ar
31、e bored. The contact of each jaw on the test mandrels shall be made gripping 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 les
