Description

technical field [0001] The invention belongs to the field of liquid jet polishing, in particular to an acoustomagnetic coupling cavitation auxiliary liquid jet polishing device and a use method. Background technique [0002] As the demand for surface quality and processing efficiency of micro-miniature optical components (such as 3D curved glass, mobile phone cameras and optoelectronic communication equipment, etc.) continues to increase, their processing accuracy needs to reach the nanometer level or below, which requires traditional After turning, grinding and grinding, there is an additional ultra-precision polishing process to improve the surface quality of optical components. At present, the jet polishing technology represented by liquid jet, micro-abrasive water jet and cavitation jet is gradually applied to the ultra-precision polishing of micro-miniature optical components, but there are still problems such as unsound theoretical methods, unstable material removal an...
