- MACOR® (Machinable Glass Ceramic (MGC))
Essential factors for successful processing of MACOR® are proper machining speeds and the selection of a suited coolant. The glass-ceramic can be processed with conventional HSS tools although it is recommended to use carbide tools for more extended wear. Further, it is recommended to use water-soluble coolants designed for sawing and grinding glass or ceramics. Post firing after machining is not necessary. On the right, you will find typical values for the machining of MACOR®
