Wear And Corrosion Resistant Industrial Ceramic Parts Petroleum Industry Equipment

Machinable Glass Ceramic is an outstanding engineering material and is machinable with ordinary metalworking tools. It has a low thermal conductivity and is a useful high temperature insulator. Further more, it is an excellent electrical insulator and has a high maximum use temperature (800°C continuous, 1000°C peak). No longer is it necessary to staff a ceramic specialist with high temperature kilns or specialized diamond grinding equipment.

Machining

Machining tolerances are surprisingly tight, up to10 microns (.0005”).It can bemachined to a surfacefinishof less than 0.5 micron (20 microinch) and polished to a smoothness of 125 angstroms 0.5 microinch) average roughness. Most conventionalmachining processes can be used. Configurationsare limited only by available equipment and theexperience of the machinist.

The manufacturing route for advanced ceramics include: consolidation of the powder, green machining of the compacted powder, sintering and finally, when required diamond grinding.

>>> Green Machining
This technique is commonly applied to as-pressed parts which are still in a chalky condition. Common metalworking machines are used to machine the part in this soft condition, as greater material removal rates are possible than by post-sintering operations such as diamond grinding. As-fired green machined components are subject to tolerances of approximately +/- 1%. To achieve tighter tolerances, diamond grinding must be employed.
