The invention provides a nano layer lubrication diamond grinding wheel grinding method based on a shock wave cavitation effect. The method is characterized in that after an air pressure adjusting valve is opened, shock waves generated by an accelerating tube push nano particles to move forwards, and then the nano particles are accelerated by a small laval tube to obtain a high initial speed; meanwhile, a wave source of a shock wave accelerating module generates high-frequency and high-strength shock waves to impact the nano particles with the initial speed, so that the nano particles are continuously accelerated downwards in the axial direction of a large laval tube until the nano particles are embedded into the surface of a grinding wheel at the highest speed to form a nano layer; the other wave source is used for cleaning impurities on the surface of the grinding wheel; and in the machining process, the nano particles of the nano layer are autonomously released in a grinding core area, so that self-lubricating cooling in a grinding area is achieved. The method greatly enhances the lubricating cooling effect, and also conforms to the concept of green development.
