A fine-grained diamond compact synthesized using a mixed sintering agent of magnesium carbonate and oxalic acid dihydrate was evaluated through precision machining of aluminum alloys in comparison with natural single crystals of diamond. The flank wear of the tool made of polycrystalline compact was half that of single crystal. And the tool made of polycrystalline compact achieved as excellent a surface finish as that of single crystal.
