ISO 3089:2005 pdf download.Machine tools — Test conditions for self-centring, manually-operated chucks with one-piece 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 rotational 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 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 accuracy of machines operating under no- load or finishing conditions
3 Preliminary remarks
All dimensions and tolerances in this International Standard are expressed in millimetres.
4 Accuracy classes
Unlike the previous edition, this International Standard specifies only one accuracy class.
5 Geometric tests
5.1 Master pinion
Tightening of the chuck on the test 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 by the manufacturer.
