Grinding method using nanolayer-lubricated diamond grinding wheel based on shock wave cavitation effect

A grinding method using a nanolayer-lubricated diamond grinding wheel based on a shock wave cavitation effect, wherein the method includes:

• step S1. generating compressed gas and storing the compressed gas in a gas tank;
• step S2. inputting the compressed gas into a gas acceleration tube, which has a push plate, a high pressure chamber and a low pressure chamber;
• inputting nanoparticles into the low pressure chamber and inputting compressed gas into the high pressure chamber, in which the compressed gas is further pressurized by the push plate until pressure of the compressed gas reaches a first preset threshold;
• Step S3. Opening the high pressure chamber, so that the compressed gas is delivered to the low pressure chamber with a streamline tightening structure to push the nanoparticles therein to a second wave focusing device;
• Step S4. setting two shock wave sources, a first shock wave source and a second shock wave source, which are both facing towards the grind wheel;
• Step S5. generating shock waves in sequence with the two shock wave sources, wherein the first shock wave source generates first shock waves and enhance the first shock waves using a first wave focusing device in front of the first shock wave source, and the second shock wave source generates second shock waves and brings the nanoparticles in the second wave focusing device to impact the grind wheel;
• Step S6. forming a uniformly distributed nanolayer on a grinding wheel surface by using the shock waves.
