• Pull-out
• Scanning Electron Microscope

The process of polycrystalline diamond compact (PDC) cutter turning granite was investigated by means of tools microscope and dynamometer, and the fracture section of worn PDC was studied by scanning electron microscope. The results indicate that the process of polycrystalline diamond compact (PDC) cutter turning granite is composed of initial wear, fast wear and stable wear, and single force curve of the process is cyclical fluctuate, and the wear of PDC cutters is the result of grinding and impact as well, and the abrasion mechanism of PDC includes several mechanism such as grinding abrasion and fatigue wear. The wear and fracture of PDC are due to the break of W/Co loaded by applied loading and the pull-out of the diamond particles.
