LAPPING APPARATUS AND LAPPING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a lapping apparatus and lapping method to wash cleanly the lapping tool to lap precision optical parts, their molds and the like. SOLUTION: The lapping apparatus 1 is provided with the magnetic field generating part 6 which generates the specified magnetic field and is arranged the specified distance off the surface of the lapping tool 2, and at the upstream side of the washing brush 3 in terms of the rotating direction of the lapping tool 2 so that the magnetized chips 10 sticking to the surface of the lapping tool 2 are ploughed to be completely washed down and removed by the root with the washing brush 3 provided at the downstream side of the rotating direction of lapping tool 2.
