Ceramic Hard Machining

Kadco ceramics is dedicated to the precision diamond machining of hard materials into intricate shapes.

Ceramic hard machining.

Since 1982 kadco has focused on providing engineering assistance and production solutions to a broad spectrum of industrial and r d needs. Additionally materials like silicon carbide sic may not fit the precise definition of a ceramic material but they can still be classified as part of the ceramic family. We machine these materials to very precise tolerances many times measured in millionths of an inch for dimension flatness wedge and roundness or cylindricity. The main advantage that mixed ceramic has over cubic boron nitride cbn in hard part machining applications is the effect on part production costs.

Whilst cbn has a better tool life the cost per edge of a ceramic insert is a fraction of that of cbn approx one twentieth whilst feed rates chip thickness around 0 1mm and cutting speeds. Following a final firing when as fired tolerances are not sufficient fine diamond machining grinding using diamond impregnated cutters is often required.
