Polishing systems and methods for polishing complex polycrystalline diamond compact geometries

A system for polishing a polycrystalline diamond compact, comprising:

• a housing including internal surfaces defining an enclosed chamber therein, the housing including a fixture configured to hold at least one polycrystalline diamond compact therein such that at least a portion of a surface of the at least one polycrystalline diamond compact is exposed within the chamber;
• at least one fluid inlet leading into the chamber from outside the housing;
• at least one fluid outlet leading out from the chamber from inside the housing;
• a fluid reservoir for holding a working fluid therein;
• a pump for producing flow of pressurized working fluid through the enclosed chamber within the housing and across the at least a portion of a surface of the at least one polycrystalline diamond compact exposed within the chamber;
• and
• fluid conduits defining a circular fluid pathway extending from the fluid reservoir to the pump, from the pump to the at least one fluid inlet, and from the at least one fluid outlet to the fluid reservoir.
