What it is
How it works
General reference — not yet source-verifiedLapping machines use a rotating flat plate called the lapping plate. An abrasive slurry is applied to the plate. Workpieces are held in place by carriers and pressed against the plate by weights. The relative motion between the plate and the workpiece removes material through abrasion.
