BS ISO 2772:2019 pdf download – Test conditions for box type vertical drilling machines — Testing of the accuracy This document specifies, with reference to ISO 230-1, geometrical tests on general purpose and normal accuracy box type vertical drilling machines. It also specifies the applicable tolerances corresponding to the above-mentioned tests. This document deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) or to machine characteristics (such as speeds, feeds, etc.), which are generally checked before testing of machine accuracy. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements 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.
