Abstract

The invention relates to a self-adjustment magnetorheological flexible polishing abrasive wheel and a polishing method thereof. The self-adjustment magnetorheological flexible polishing abrasive wheel comprises a fixing ring, an inner gear, an abrasive wheel ring, a gear shaft, a synchronous rotation gear, a planetary gear, a rotary shaft and a cylinder permanent magnet. The rotary shaft is arranged in the abrasive wheel ring. The cylinder permanent magnet is arranged in a through hole formed in the lower end of the rotary shaft. The inner gear is arranged on the upper portion of the abrasive wheel ring. The fixing ring is arranged at the top of the inner gear and fixed to a machine tool. An abrasive wheel connector is arranged at the top of the abrasive wheel ring and the top of the fixing ring. The abrasive wheel connector is connected with the abrasive wheel ring. An outer gear is arranged on the abrasive wheel connector. The gear shaft is arranged on the abrasive wheel connector. The planetary gear is arranged on the gear shaft. The synchronous rotation gear is arranged at the upper end of the rotary shaft. The planetary gear is engaged with the outer gear arranged on the abrasive wheel connector. The synchronous rotation gear and the planetary gear are engaged with the inner gear. According to the self-adjustment magnetorheological flexible polishing abrasive wheel and the polishing method thereof, replacing and self-sharpening of abrasive materials and real-time recovery of the shape of an abrasive wheel block are achieved, and the self-adjustment magnetorheological flexible polishing abrasive wheel and the polishing method thereof are suitable for efficient, super-smooth and uniform grinding and polishing of planes of photoelectronic/microelectronic substrates and optical elements.

Description

technical field [0001] The invention relates to a self-repairing magnetorheological flexible polishing wheel and a grinding and polishing method thereof, which is particularly suitable for ultra-precision grinding and polishing of optoelectronic / microelectronic semiconductor substrates and optical elements, and belongs to the technical field of ultra-precision processing. Background technique [0002] In the LED field, single crystal silicon (Si), single crystal germanium (Ge), gallium arsenide (GaAs), single crystal silicon carbide (SiC) and sapphire (Al 2 o 3 ) etc., as semiconductor substrate materials, also require an ultra-flat and ultra-smooth surface (roughness Ra below 0.3nm) to meet the requirements of epitaxial film growth, and require no defects and no damage. As one of the core components of optical devices, in order to achieve good optical performance, the surface precision of optical components needs to be ultra-smooth (roughness Ra should be less than 1nm), a...
