In the context of specific function conditions, it may prove necessary to machine the surfaces of ceramic components. Primarily, this serves tribological purposes, i.e. the use of grinding, lapping or vibratory grinding to create an appropriate standard of surface quality that it is not possible to achieve during the actual manufacturing process.
The geometric shaping processes for ceramic components, irrespective of whether that process involves extrusion, pressing or injection molding, are prone to process-related fluctuations in dimensional integrity. Partial and retrospective machining of components is a way to assure reproducible compliance with even the tightest of tolerances.
