Design guidelines

▶In general, the less we do to the ceramic part after it is sintered,

the less it cost. Here is a list of of the processing after sintering in

order if cost increasing to ceramic part.

●Sintering

●Grinding                                                                                              

●Lapping

●Polishing

▶The different choice of machining also cause the different cost of ceramic part. Below there is a list of machining operations in order of cost increasing to ceramic part.

●Surface Grinding

●Cylindrical Grinding

●Milling or Drilling

●Lapping

●Hand finishing

▶Avoid sharp internal corner and undercut to save the cost and away from the stressriser

▶Avoid knife edge features, because the brittleness of the ceramics.

▶Provide radius and chamfer in each edge to prevent from chipping whenever possible

▶Tight tolerance causes expensive cost.
