This standard indicates, with reference to standard NBN 762 - 1968 — Test code for machine tools — the geometric verifications and practical tests of machines for grinding flat surfaces with a grinding spindle with a vertical or horizontal axis as well as the tolerated deviations corresponding to machines of general use and normal precis on. It concerns machines with rectilinear grinding movements and a movable table, excluding machines with a fixed table or circular movement (**). It only deals with controlling the precis on of the machine. It does not concern the examination of the operation of the machine (vibrations, abnormal nois s, hard points in the movement of organs, etc.), nor that of the characteris ics (speeds, feeds, etc.), examinations which must generally precede that of precis on.
