Metallographic phase automatic corrosion device

The utility model discloses an automatic metallographic corrosion device, and particularly relates to the technical field of metallographic pretreatment, the automatic metallographic corrosion device comprises a device shell, a control panel is arranged on the front side of the device shell, a corrosion module is arranged on the device shell, a cleaning module is arranged on the device shell, and a rotary sample table is arranged at the top of the device shell. A plurality of sample placing grooves are formed in the rotary sample table, water outlets are formed in the bottoms of the sample placing grooves, and a waste liquid outlet is formed in one side of the bottom of the rotary sample table. Through the arrangement of the corrosion module, the cleaning module and the rotary sample table, the requirement for experience of workers is not high, the use difficulty is reduced, meanwhile, the corrosion time can be accurate, the dosage of a corrosion reagent can be quantified, and the problems that due to imprope
