Reaffirmed 2023

1. Scope

This standard describes both geometrical and practical tests on vertical boring and turning mills having single or double columns with table diameter up to 1 600 mm, and the corresponding permissible deviations, with reference to IS 2063 (Part 1).

It deals with the verification of accuracy and applies neither to the testing of the running of the machine (vibrations, abnormal noises, stick slip motion of components, etc) nor to the machine characteristics (speeds, feeds, etc) which shall generally be checked before testing the accuracy.
