Abstract: The present invention relates to an automatic lapping method for lapping a work piece and a lapping apparatus using the same. The lapping apparatus laps a work piece by moving the mounting base 103 relatively to a lapping plate 104. On a coarse processing step, the lapping plate 104 is controlled with high speed as detecting a remaining amount for lapping the work piece. Then, on a fine processing step, said lapping plate 104 is controlled with low speed by detecting that the remaining amount h for lapping said work piece has reached to a predetermined amount H0. Thereby, it becomes possible to continuously execute the coarse processing and the fine processing in one lapping apparatus.
