適用范圍：1.Describes both geometrical and practical tests on horizontal spindle capstan, turret and single spindle automatic lathes for machinable bar diameter greater than 25 mm and gives the corresponding permissible deviations, with reference to IS : 2063-1962 'Code for testing machine tools'.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.Note—Machines with contouring numerical control are excluded from the scope of this standard, and also lathes with sliding heads and lathes with rotating tools.
