1.Describes both geometrical and practical tests on external cylindrical grinding machines with a movable table with swing diameter up to 800 mm and centre to centre distance up to 1 600 mm, and the corresponding permissible deviations with reference to IS: 2063-1962 'Code for testing machine tools '. This test chart is also applicable for angular wheel head machines with necessary tests as applicable, according to manufacturer's recommendations.
1.1 It deals only 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.
