High-chromium ball surface polishing device

The utility model discloses a high-chromium ball surface polishing device, and relates to the field of high-chromium ball machining. The high-chromium ball surface grinding device comprises a grinding device table body, an air pump and an electric push rod are fixedly connected to the grinding device table body, the output end of the electric push rod is fixedly connected with a sliding table, the sliding table is slidably connected to the grinding device table body, a motor is fixedly connected to the sliding table, and a grinding disc is arranged at the output end of the motor. When the high-chromium ball surface grinding device is used, suction force is provided through the arranged air pump, then a high-chromium ball needing to be machined is adsorbed to the position of the suction cup, then the electric push rod drives the sliding table, the motor and the grinding disc to integrally and transversely slide, and when the motor works, the grinding disc is driven to rotate, and the high-chromium ball is grou
