Machinable glass ceramic is a highly electrical insulating, heat insulating, vacuum tight composite material of glass and ceramics. It is machinable with common tungsten carbide or high speed steel cutting tools by turning, milling, drilling and sawing. Due to the machinability, customers can produce the ceramic parts in their own common workshop or laboratory, mainly for applications as electrical insulators, vacuum components, etc. Different sizes of standard length or customers' parts are available.

Advantages:
Glass ceramics can be machined with conventional metal working machinery. It is not necessary to sinter after machining, because strength, hardness and zero-porosity remain intact during machining. Machinable glass ceramic have the following power feature.

a) Is machinable with ordinary metal working tools.
b) Allows fast turnaround,no post firing required.
c) Holds tight tolerances, up to .0005"
d) Withstands high temperature, up to 800??
e) Is clean, no outgasing and zero porosity

MGC: Machinable glass ceramic have the following applications:
a) Electrical or thermal insulator
b) Structural components
c) Semi-conductor processing
d) Electrical and opto-electronic equipment
e) Many other uses.
