Description of BS 4656-22:1988 1988This International Standard defines machining operations on vertical turning and boring lathes with one or two columns and a single fixed or movable table. It defines and summarizes the different types of machines and establishes a glossary for the various types of machine tool. It indicates, with reference to ISO 230-1, both geometrical and practical tests for such vertical lathes, and gives the corresponding permissible deviations for general purpose use machines of normal accuracy.
It deals only with the verification of accuracy of the machine. It does not apply to the running of the machine (vibrations, abnormal noises, stick-slip motion of components, etc.) or to machine characteristics (speeds, feeds, etc.), which should generally be checked before testing accuracy. Accuracy requirements and geometrical and practical tests with reference to BS 3800.
