How To Machine Machinable Ceramics

Ceramics can be made from several different types of hard metal oxides or nitrides.

How to machine machinable ceramics.

Machinable is a term used to describe ceramic materials that after sintering can be machined with traditional metalworking machine tools. That is they can be turned milled drilled and saw cut without the need for diamond tooling. As with most other hard machining operations coolant must be used to dissipate heat and to flush away the ceramic swarf which can damage both the machine and the production. One of the legacy products since the scientific community discovered the benefits of hot pressed hbn grade a is specified into applications from a long time ago.

In stock and ready to ship. Also fine diamond machining is used at ceramco to machine non ceramics including quartz. Moreover the loose diamond debris can scratch or mar the ceramic part. Combat bn machinable ceramics grade a.

For the low to medium volume precision work macor is a material that even a modestly equipped shop can machine into precision ceramic parts. Macor is a corning inc. No machining all depending upon the requirements of the oem ceramic part the geometry and final tolerances can oftentimes be achieved during the near net shaping process. 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.

Macor is one of the few ceramics that can be machined using regular metal working tools. 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. Combat machinable ceramics grade a uses b 2 o 3 binder system to add mechanical strength to hot pressed hbn. This is the most cost effective solution.
