This International Standard specifies the nomenclature appropriate to the various parts of multi-spindle boring machines in order to assist manufacturers and users in the identification of these parts. NOTE - In addition to terms used in the three official IS0 languages (English, French and Russian), this International Standard gives the equivalent terms in the German, Spanish, Italian and Swedish languages; these are published under the responsibility of the member bodies for Germany, F.R. (DIN), Spain (AENOR), Italy (UNI) and Sweden (SIS). However, only the terms given in the official languages can be considered as IS0 terms. This International Standard applies to those machines designated by the number 12.42 in IS0 79841
