Polishing device for shaft part machining

The utility model relates to the technical field of part machining, in particular to a polishing device for shaft part machining, which comprises a machine body and a table top fixedly connected to the upper surface of the machine body, a protective shell is fixedly connected to the middle of the upper surface of the table top, and hydraulic cylinders are mounted on two sides of the protective shell. According to the polishing machine, the overall structure is more reasonable, the design is more optimized, dust and water spots can be prevented from splashing during polishing by arranging the protective shell, the polishing machine is more environment-friendly, the polishing efficiency is improved, and the polishing machine is suitable for popularization and application. And the two carborundum grinding wheels are arranged and can move in the grinding process, so that the whole shaft part can be comprehensively ground without changing the fixed position, the two carborundum grinding wheels can be installed at
