The invention provides a reinforced cutting machine comprising a control device, a drive device, a linkage device, a cutting blade, a worktable and a frame. The frame is arranged on the worktable, the control device penetrating the frame is connected with the drive device, and the cutting blade is connected with the drive device through the linkage device. The control device is a servo motor provided with a rotating shaft penetrating an upper beam to be connected with the drive device. The drive device is of a screw-nut set, the lead-screw end of the screw-nut set is connected with the drive device and the other end of the screw-nut set is connected with the linkage device. Since the servo motor is utilized to provide power, the reinforced cutting machine can realize accurate positioning, speed adjustment and zero pollution and can be applied to food and medicine industries. The parallel-bar linkage mechanism is used to transmit power to the cutting blade so that force reinforcement is achieved and motion precision of the reinforced cutting machine is increased. Due to the screw-nut set for drive, driving precision is high and friction resistance is low.
