Embodiment 1
[0019] S1. Surface treatment: Place the high-precision mechanical parts that need to be polished on the workbench, first clean up the metal debris and sundries stuck on the surface of the high-precision mechanical parts, and rinse them with clean water after cleaning ,dry;
[0020] S2. Chemical treatment: Spray acidic solution on the surface of high-precision mechanical parts, let it stand for 5 to 10 minutes, rinse with acidic solution, rinse with clean water, and dry;
[0021] S3. Mechanical polishing: Spray polishing liquid on the surface of high-precision mechanical parts, rotate the mechanical grinding wheel at a speed of 200r / min, and polish the surface of high-precision mechanical parts until the surface roughness of high-precision mechanical parts is Ra0. 1-0.2mm to stop the polishing process, clean up the metal debris and sundries produced on the surface of the high-precision mechanical parts every 15 minutes during the polishing process, and spray the polishing liqui...
Embodiment 2
[0024] Except that the composition of the raw materials of the polishing liquid is different, the others are the same as in Example 1.
[0025] The polishing liquid, according to the total weight of 100%, includes the following raw materials in parts by weight: sodium tetraborate 6%, benzisothiazolinone 1.0%, sodium dodecylsulfonate 5%, diamond composite abrasive 6%, Perfluoroalkyl polyoxyethylene ether 1.8%, modified cubic boron nitride 1.5%, polyether modified silicone oil 1.0%, and the balance is water.
