A lapping carrier is a workholding plate used in double-sided planetary lapping equipment. A carrier keeps parts separated in patterned openings while the machine drives the carrier through the abrasive process between opposing plates.
Double-sided lapping carriers are used during bulk or intermediate surface-finishing operations when flat parts need simultaneous processing on both sides. Such carriers sit between earlier shaping or slicing steps and later cleaning, inspection, or finer finishing steps.
Double-sided lapping carriers are used for flat workpieces that need controlled handling during abrasive planarization or thickness reduction. Such carriers are common where fragile or precision parts must be held in repeatable positions throughout the finishing pass.
