Machinable Glass Ceramic Characteristics:
The most outstanding characteristic of Machinable Glass Ceramic Disc is that it can be processed by turning, milling, planing, grinding, drilling, sawing and tapping with standard metal processing tools and equipment. It can be processed into products with complex shapes and high precision requirements. Although glass ceramics are brittle and hard materials, as long as the processing route and clamping mode are reasonably determined, the machining method is paid attention to, and the cutting parameters are accurately selected, the finish reaches 0.5 μ m and the machining accuracy is controlled at 0.005 mm.
