The invention discloses a novel circular sawing machine with an automatic discharging function. The novel circular sawing machine comprises a case and further comprises a cutting mechanism, a clampingmechanism and a discharging mechanism which are mounted on the case. The clamping mechanism is mounted on the lower portion of the cutting mechanism through a rotary disc mechanism, and the discharging mechanism is movably arranged on the rear side of the clamping mechanism. According to the novel circular sawing machine with the automatic discharging function, a to-be-machined pipe is clamped through the clamping mechanism and cut through the cutting mechanism, and the cut pipe is conveyed into a receiving box in a clamped mode through the discharging mechanism, so that automatic cutting anddischarging of the pipe are achieved, the cutting precision is improved, and the labor intensity of workers is reduced.
