IS 1878 : Part 3 : 1998 Test chart for general purpose parallel lathes Part 3: Lathes with swing over bed over 1600mm ad upto 2500mm

1 Scope

This standard describes both geometrical and practical tests ongeneral purpose parallel lathes with swing over bed more than 1 600mm and up to 2 500 mm and the corresponding permissible deviations,with reference to IS 2063 : 1988 `Acceptance code for machine tools- Geometric accuracy of machines operating under no-load orfinishing conditions (first revision).

It deals only with the verification of accuracy and appliesneither to the testing of the running of the machine (vibrations,abnormal noises, stick-slip motion of components, etc) nor to themachine characteristics (speeds, feeds, etc) which shall generallybe checked before testing the accuracy.
