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

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.
