IS 2367 : 1981 Test chart for box type vertical drilling machines

1 Scope

Describes both geometrical and practical tests ongeneral-purpose and normal-accuracy box-type vertical drillingmachines, and the corresponding permissible deviations withreference to IS : 2063-1962 `Code for testing machine tools`.

1.1 It deals only with 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.
