How To Machine Ceramic Parts

Ceramic is highly prized for its thermal resistance toughness and applications in the electrical field.

How to machine ceramic parts.

Macor machining guide how to machine macor. Macor is a corning inc. Many people are woefully unaware of just how prevalent ceramic parts are in the industry. Manufacturing by ceramic mold casting is similar to plaster mold casting in that it can produce parts with thin sections excellent surface finish and high dimensional accuracy.

Macor is one of the few ceramics that can be machined using regular metal working tools. Superior has in house capabilities to design engineer tool and manufacture these advanced ceramics in quantities ranging from one prototype part to large. 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. Manufacturing tolerances between 002 and 010 inches are possible with this process.

Corning is well know for its glass products and macor is a hybrid machinable glass ceramic that can be fabricated into intricate shapes with tolerances on the order of 0 0002 in with ordinary carbide tooling. Following a final firing when as fired tolerances are not sufficient fine diamond machining grinding using diamond impregnated cutters is often required. Conventional machining methods milling drilling turning may be applied for the ceramic parts in the presintered state. For the low to medium volume precision work macor is a material that even a modestly equipped shop can machine into precision ceramic parts.

Fine diamond machining full density parts ceramic parts fired to their full density are too hard for machining with tool steel cutters or even conventional methods. While there is a learning curve to machining macor it is certainly achievable with the correct skill and patience. Properties and considerations of manufacturing by ceramic mold casting. Today s business comprises a host of custom ceramic parts made from alumina zirconia zirconia toughened alumina steatite mullite cordierite grade a lava macor and boron nitride.
