Abstract: A lapping platen having a working surface and an abrasive coating on the working surface. The abrasive coating comprises a plurality of individual abrasive composites adhered to the working surface with an epoxy, the abrasive composites comprising diamond particles and a ceramic matrix. The diamond particles have an average particle size of 0.1 micrometers to 3 micrometers with no particle larger than 6 micrometers. The abrasive composites have an average particle size of 15 micrometers to 100 micrometers with no particle larger than 150 micrometers.
