  • Method for machining sand block into sand molding elements including sand molds and sand cores for metal casting foundry operations
    Patent number: 6386264
    Abstract: A method for machining a sand core, a cope, a drag or other molding element from a block of sand held together by binder material for use in foundry metal casting operations. The sand block is cut preferably with a diamond or carbide cutting bit of a computer numerical controlled (CNC) machine tool to cut a pattern into the sand block. A machine tool may be a mill, lathe, drill press, or other machine tool as appropriate. The sand block may be clamped in a variety of positions, and reference points are used to locate the sand block during each subsequent clamping and reclamping of the sand block to the various machine tools. The machined sand core is then inserted into a mold and used in foundry operations to create an internal cavity in a metal casting.
