Ceramics can be made from several different types of hard metal oxides or nitrides.
How to machine ceramic.
Macor is a corning inc.
Macor machining guide how to machine macor.
They have a bridgeport dedicated to making the ceramic feedscrew.
Ceramic materials can be divided into two major divisions traditional and advanced.
Macor is one of the few ceramics that can be machined using regular metal working tools.
While there is a learning curve to machining macor it is certainly achievable with the correct skill and patience.
Way beyond porcelain or china.
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.
The art of ceramic processing combined with the science of high precision machining technology have helped superior build a reputation as a premier manufacturer in this field.
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.
The grit from the ground ceramic material will most likely ruin the ways of the bridgeport.
If you machine ceramic make certain you are paid well for it.
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.
Ceramic tubes and special extruded rods requiring fine features or tolerances also fine diamond machining is used at ceramco to machine non ceramics including quartz.
To this day the company i retired from still makes the feedscrews using my technique for their inhouse assembly equipment.
