Abstract

The invention relates to the technical field of ultra-precision machining, in particular to a polishing device and method for a variable-stiffness grinding wheel assisted by magneto-rheological jet flow. The polishing device comprises a bottom plate, a sliding guide rail module, a first bearing seat, a guide wheel, a first iron core, a first coil, a workpiece, an iron core support, a second bearing seat base, a second bearing seat, a magneto-rheological elastomer grinding wheel embedded with abrasive particles, a guide pipe, a magneto-rheological polishing solution storage box, a coupler, a motor, a motor support, a second coil, a second iron core, a base, a bolt, a workpiece support, a first shaft, a second shaft, a pump, a nozzle, a pressure sensor and a third coil. Mechanical polishing and magneto-rheological polishing liquid jet flow polishing for controlling the rigidity of the magneto-rheological elastomer grinding wheel embedded with the abrasive particles through the magnetic field are carried out at the same time, and good surface machining quality and machining efficiency are achieved.

Description

Technical field [0001] The present invention relates to the technical field of ultra-precision machining, and more particularly to a polishing apparatus and method of a magneto-flow rate auxiliary shifting stroke. Background technique [0002] With the rapid development of China's manufacturing 2025, high-end equipment manufacturing industry is more powerful for superficial processing technology and process methods, especially the surface polishing technology of key components in the field of precision instruments, aerospace devices, etc., has always restricted my country's ultra-precision One of the bottlenecks developed by the processing technology. Some key components in high-end equipment are very high for their surface quality, such as optical components, semiconductor chips, route blades, motor spindles, etc., so exploring the new type of ultra-precision polishing technology is important for the development of my country's advanced equipment manufacturing industry. Realisti...
