High performance MACOR Machinable Glass Ceramic
MACOR Ceramic Rod
MACOR Ceramic Parts
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.
Our machinable glass ceramic has good machining performance, and can be turning, milling, grinding, drilling, drilling and tapping and other machining by ordinary machine tools and cutting tools. The machining accuracy can reach up to 5μ m, finish high up 0.5μ. It has a good vacuum, high and low temperature resistance, insulation and acid and alkali corrosion resistance ect properties.
