Carving Extremely Hard and Brittle Material with a Laser Beam

By: Dr. Lim Gnian Cher Laser is a potential tool for machining structural profiles on hard and brittle materials such as ceramics and carbides that traditional tools and methods find them near impossible to do.  EDM (electro-discharge machining) may be used for substrates that are conductive, such as tungsten carbide.  However, drilling small holes or […]
