| Abstract: | The largest diameter polycrystalline diamond compact with diameter 51mm was synthesized on domestic cubic press.Scanning acoustic microscope（SAM） analysis showed that there were no defects such as delamination,cracks and non-uniform thickness of PCD layer in batch samples.Cutting test indicated that the cutting performance of our company sample was similar to that of foreign company when turning cemented carbide. |
