The utility model discloses a PCD (Poly Crystal Diamond) formed milling cutter capable of optimizing cutter structural strength and improving collapse resistance, which comprises a tungsten steel milling cutter body, four milling cutter grooves are arranged on the outer surface of the front end of the tungsten steel milling cutter body, a cutter pit groove is arranged at the front end of the tungsten steel milling cutter body, a PCD blade is welded on the inner side of the cutter pit groove, and the PCD blade is welded on the outer side of the tungsten steel milling cutter body. The cutting face of the PCD blade is provided with a first relief angle and a second relief angle. The tungsten steel milling cutter body and the PCD blade are welded together in a brazing mode, so that the cutting strength of the cutter body is improved, the service life of the cutter body is prolonged, the PCD and the tungsten steel cutter body are cut together through the two-relief-angle low-speed wire feeding machining process, t
