The invention discloses a stainless steel pipe cutting machine which comprises a rack, two horizontal rotating rollers are arranged on the rack, the two rotating rollers are driven by a rotating motor to rotate, a supporting frame is arranged on the rack, a cutting mechanism is installed on the supporting frame, a cutting edge is arranged on the edge of the outer side of a cutting wheel, and the cutting wheel is arranged on the rack. Polishing blocks are arranged on the two side faces of the cutting wheel correspondingly, and a material receiving mechanism is arranged on the discharging side of the rack in a sliding mode. A to-be-cut stainless steel pipe is rotated through the transmission roller, then the stainless steel pipe is cut through the cutting wheel, the cutting wheel does not need to wholly descend to the position below a notch, the cut notch is more uniform and neat, and the cutting precision is higher; and a grinding ring is arranged on the cutting wheel, after the cutting edge finishes cutting,
