Published by UKAM Industrial Superhard Tools — American manufacturer of precision diamond & CBN tools since 1990. 99.5% alumina ceramic is one of the most widely used advanced ceramics in semiconductor, aerospace, electronics, medical, optics, and industrial manufacturing applications. It offers excellent hardness, dielectric properties, wear resistance, and thermal stability — but it is also highly brittle and sensitive to edge chipping during cutting.

PDC cutter grinding fails in three specific ways: thermal damage to the diamond layer, chipping at the diamond-carbide interface, and wheel glazing that stops material removal entirely. Each failure mode has a distinct cause and a distinct fix. Most process problems trace back to one of three decisions: the wrong bond system, inadequate coolant delivery, or unchanged parameters across the diamond-carbide transition zone. This guide addresses all three. It covers the material science behind PDC grinding difficulty, why vitrified bond outperforms alternative systems, how to set starting parameters, how to manage the transition zone, and what wheel specification variables actually control surface finish and tool life.
