POLISHING SYSTEMS AND METHODS FOR POLISHING COMPLEX POLYCRYSTALLINE DIAMOND COMPACT GEOMETRIES

A method of polishing a polycrystalline diamond compact ("PDC") portion of a cutting element of an earth-boring tool, the cutting element comprising a PDC portion and a carbide portion. The method may comprise securing the cutting element in a receptacle, which receptacle may seal off the carbide portion of the cutting element from a working fluid comprising a carrier fluid and abrasive particles, enclosing the cutting element in a pressurized chamber, filling the pressurized chamber with the working fluid, directing a pressurized flow of the working fluid from at least one inlet toward at least one surface of the PDC portion of the cutting element and out at least one outlet, and providing relative motion between the receptacle and the at least one inlet with a motion mechanism. A polishing tool for polishing the PDC portion of at least one cutting element of an earth-boring tool.
