Cutting machine

The invention provides a cutting machine. The cutting machine comprises a frame, a driving device, a piston and a splitting device, wherein the piston is connected to the frame in a sliding manner; the splitting device is arranged on the frame and located under the piston; the driving device drives the piston to move up and down, so that the piston applies pressure to a to-be-cut object on the splitting device and the to-be-cut object is cut by the splitting device; the driving device comprises a motor and a driving wheel; the motor drives the driving wheel to rotate; the driving wheel is connected with the piston through a rod; one end of the rod is rotationally connected to an eccentric position set on one side surface of the driving wheel, and the other end of the rod is rotationally connected to a mounting plate of the piston; and the splitting device comprises an accommodating barrel, a slicing part, a dicing part and a driving part for driving the dicing part to move. The cuttingmachine has reasonable s
