Acceptance conditions for vertical turning and boring lathes with one or two columns and a single fixed or movable table -- General introduction and testing of the accuracy
This International Standard defines machining operations on vertical turning and boring lathes with one or two columns and a Single fixed or movable table. lt defines and summarizes the different types of machines and establishes a glossary for the various types of machine tool. lt 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. NOTE - In addition to terms used in the three official ISO languages (English, French and Russian), this International Standard gives the equivalent terms in German, Italian and Swedish; these have been included at the request of Technical Committee ISO/TC 39 and are published under the responsibility of the member bodies for Germany F.R. (DIN), Italy (UNI) and Sweden (SIS). However, only the terms given in the official languages tan be considered as ISO terms. lt deals only with the verification of accuracy of the machine. lt 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. 1, which should generally be checked before testing accuracy.
