Problems solved by technology

[0003] The polishing liquid used in the existing magnetic jet polishing technology is mostly based on the conventional magnetorheological polishing liquid, but due to the particularity of the magnetic jet processing process, it requires that the polishing liquid not only have good rheological properties, but also under high pressure And under high-speed impact, it has good rust resistance and suspension stability, while conventional magnetorheological polishing fluid is difficult to meet the above requirements

Description

technical field [0001] The invention belongs to the field of optics and metal precision processing and manufacture, and in particular relates to a magnetic jet polishing fluid and a preparation method thereof. Background technique [0002] As early as the 1990s, the Belarus Institute of Heat and Mass Transfer used magnetorheological fluid and added polishing particles to realize the polishing of optical components, and optimized and promoted this method, and proposed magnetorheological polishing technology. This technology has been successfully applied in the field of ultra-precision machining. Magnetic jet polishing technology is a new processing method based on magnetorheological polishing technology. Its main advantage is that it can achieve ultra-precision machining of complex structures, especially complex cavities, and has high material removal efficiency and polishing quality. This technology is different from water jets. Its polishing process does not require ultra-...
