The polishing solution is one of the key elements for carrying out ultra-precision machining on a workpiece, and the performance of the polishing solution directly influences the quality of the polished surface. The polishing slurry is typically composed of an ultra-fine solid particle abrasive (e.g., nano-SiO)2、Al2O3Particles, etc.), surfactant, stabilizer, oxidant, chelating agent, deionized water, solid particles for grinding, and chemical oxidant for corrosion and dissolution.
In the polishing process, the polishing solution is one of the important process factors affecting the efficiency and quality of the polishing process. The traditional polishing solution is usually supplied by a pump, but because the polishing solution has high abrasive concentration and high viscosity in some polishing processes, the pump often causes the blockage of the polishing solution and the damage of internal elements of a pump body. Therefore, the polishing liquid is added into the polishing disc regularly in the manual filling mode mainly adopted in the polishing process of the high-viscosity polishing liquid at present. According to different procedures and process requirements, the additive is generally added once every 10 minutes to 30 minutes. The polishing solution filling method has the following main problems: 1) a large amount of manpower is consumed, and the efficiency is low; 2) the addition amount of the polishing solution is difficult to control; 3) the polishing solution has poor suspension performance and is easy to precipitate after being placed for a period of time; 4) real-time charging cannot be realized.
