Machining MACOR®

Machining speed and coolant are decisive for successful machining. Read all about the machining of MACOR® here.

MACOR® composition

MACOR® glass ceramics consist of a glass matrix containing mica crystals. Its composition of 55 % fluorophlogopite mica and 45 % borosilicate glass gives rise to a microstructure that can be machined into complex shapes with conventional metalworking tools.
