BSI BS 4656-4:1971

This Part of this British Standard specifies requirements for the accuracy of milling machines of bed type with horizontal or vertical spindle by establishing permissible deviations from certain essential dimensional and geometrical characteristics, and by prescribing, by reference to BS 3800, the details of the tests to be carried out to verify compliance with these requirements.

The standard deals only with the verification of accuracy, and does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components etc.) nor to machine characteristics (speeds, feeds etc.) which should generally be checked before testing accuracy. Definitions and terminology are given in Appendix C.

NOTE The title of the British Standard referred to in this standard is given on page ii.

Specifies accuracy requirements and geometrical tests with reference to BS 3800. Relates to machines in general use and of normal precision. Does not apply to testing of the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc.) or to machine characteristics such as feeds, speeds etc. Appendix C gives terminology that is technically equivalent to ISO 1984/0.
