Polycrystalline diamond(PCD)tools have significant advantages in the efficient and high precision machining of hard and brittle materials,but conventional PCD tool manufacturing technology has problems such as low pro-cessing efficiency and limitations,the laser machining is an effective technology to achieve efficient and high quality machi-ning of PCD tools.This paper describes the removal mechanism of laser processing of PCD materials,outlines the influence of laser processing wavelength,pulse width and other process parameters on the processing quality of PCD materials,high-lights the current status of the application of laser processing technology in the cutting edge,surface texture and ablation forming of PCD tools,and introduces the progress and status of the research and development of domestic laser processing e-quipment.
