The invention discloses a cylindrical rapid-shaping combined cutter. The cylindrical rapid-shaping combined cutter comprises a cutter handle which is arranged on the rotating centerline of the cutter, wherein a cutter frame disc is arranged at one end of the cutter handle, a plurality of tool racks which are used for fixedly arranging machining tools are axially arranged at the outer edge of the cutter frame disc, each tool rack comprises a pair of cutting frames which are arranged at the two sides of the rotating centerline of the cutter, excircle cutting knives, of which knife heads are pointed to the direction of the rotating centerline of the cutter, are arranged at one ends, far away from the cutter frame disc, of the cutting frames, fixing grooves are axially formed in the cutting frames between the cutter frame disc and the excircle cutting knives, and chamfer cutters are arranged between the fixing grooves of the cutting frames at two sides. According to the cylindrical rapid-shaping combined cutter, the problems in the prior art that when an excircle surface of an irregular workpiece is machined, the working procedures are many, the work efficiency is low, the production cost is high and the product quality is difficult to guarantee are effectively solved, and the substantial effects of simple process, high work efficiency, low production cost and good product quality are achieved when the excircle surface of the irregular workpiece is machined by adopting the cylindrical rapid-shaping combined cutter.
