Machinable glass ceramics
Machining glass-ceramic requires specialized knowledge and skills to ensure proper handling and precision. Turning involves rotating the material against a cutting tool to create cylindrical shapes, while milling uses a rotating cutter to remove material from the surface. Drilling involves creating holes in the glass-ceramic using a drill bit, and tapping is the process of creating internal threads. Each of these techniques plays a crucial role in shaping the glass-ceramic into the desired form, making it a versatile material for various applications. With the right tools and techniques, machinable glass-ceramic can be transformed into intricate and precise components that meet specific requirements..

MACOR® Machinable Glass Ceramic
Macor is a unique material that offers exceptional engineering properties. Its ability to be machined using regular metalworking tools sets it apart from other ceramics. This versatile material combines the strengths of technical ceramics with the flexibility of high-performance plastics. Macor is non-porous and, once properly baked, it remains free of outgassing. Its strength and rigidity make it a reliable choice, as it does not exhibit creep or deformation like high-temperature plastics. Additionally, Macor's machinable glass ceramic composition provides excellent resistance to radiation, making it a valuable option for various applications.
Properties of MACOR® Glass Ceramic
MACOR® has a continuous use temperature of 800°C and a peak temperature of 1000°C. It offers excellent high-temperature electrical insulation properties with an electrical breakdown strength of 40KV/A per millimeter.
 | Industry Applications MACOR® builds value in every field : |
• Constant and ultra-high vacuum environments • Laser technology • Semiconductor / Electronic • Aerospace / Space • Medical/ Laboratory equipment • Fixtures • Chemical • Automobile • Military • Nuclear |
