Abstract
The invention discloses a PCD formed milling cutter. The PCD formed milling cutter comprises a cutter body, and an edge strip sheet is welded to the cutter body. The edge strip sheet is welded and attached to the annular end face of the front end of the cutter body. A chambering blade is formed in the front end of the edge strip sheet. Two cutting edge chamfering portions are arranged on the two sides of the front end of the chambering blade and comprise the first cutting edge chamfering portion and the second cutting edge chamfering portion. Three V-type annular groove thread openings forming sharp angles of 60 degrees are formed in the chambering blade. A rough reaming blade and a fine reaming blade are formed in the rear end of the edge strip sheet. A third cutting edge chamfering portion is arranged at the front end of the rough reaming blade. A fourth cutting edge chamfering portion and a fifth cutting edge chamfering portion are arranged at the front end and the rear end of the fine reaming blade. A primary rear angle and a secondary rear angle are arranged on the chamfering blade. In this way, the functions of chambering, milling, reaming and chamfering can be achieved, so that the size of a machined product is more stable, and the cutter replacing frequency is lowered; and the PCD formed milling cutter is machined in place after being clamped at a time, and the machining efficiency of the product is improved.
