MACHINED CERAMICS
(Quantities, methods, materials, applications, lead-times, tolerances)
|
•
|
When
small quantity orders for prototype samples or short production
runs do not justify construction a production tool, our machined
ceramics are the best solution.
|
|
•
|
These materials are machines in the "green" state to exacting tolerances, and then kiln fired. |
|
•
|
Standard
machined tolerances are 1/2% or .005" per inch, with a minimum
of .005". Tighter tolerances may be available depending upon
the specific configuration.
|
|
•
|
Our
primary machined ceramic is Aluminum Silicate. This material is
well suited for both electrical and high temperature applications
up to 2,800 degree Fahrenheit. See the table below for the properties
of Aluminum Silicate. Other machinable materials are available for
specific applications.

|
•
|
Machining
methods include saw cutting, milling, turning, and grinding.
