The invention relates to slicing equipment, in particular to an automatic ham sausage slicing machine for catering. Therefore, the technical problem of the invention is to provide an automatic ham sausage slicing for catering, which is high in slicing efficiency, does not easily damage ham sausages and is safe. The automatic ham sausage slicing for catering comprises a bracket, supporting legs, arotating shaft, a disc-shaped shell body, a rotating disc, a funnel, a first supporting column and the like, wherein the supporting legs are arranged on the left side and the right side of the bottomof the bracket, the disc-shaped shell body is arranged on the left side of the top of the bracket, the rotating shaft is arranged at the circle center position of the disc-shaped shell body in a rotary manner, the rotating shaft is provided with the rotating disc, and the rotating disc is located in the disc-shaped shell body. The ham sausages are sliced by a slicing mechanism, an air cylinder pushes multiple slicing cutters to move right to cut off the ham sausages, thus there is no need to cut off the ham sausages manually, security accidents caused by manual operation in the slicing processare avoided, a motor rotates to drive the rotating disc to rotate, therefore there is no need to rotate the rotating disc manually, and the slicing speed is high.
