  • Method for machining parts made of tungsten and of tungsten with thoria
    Patent number: 4766665
    Abstract: A method is disclosed for shaping parts made of tungsten and of tungsten with thoria. The method involves machining the parts with a machining apparatus wherein the machining tool is made of diamond or material of which tungsten carbide is the main phase, the material having a hardness of greater than about 91 Rockwell A, the machining being done at a speed of from about 40 to about 120 surface feed per minute, and a feed rate of from about 0.0002 to about 0.006 inches per revolution. Machining of parts made of tungsten is done with cooling with a halocarbon solvent. Machining of parts made of tungsten and thoria can be done with or without cooling.
