More Information
Summary:The utility model discloses a large feed milling cutter which comprises a cutter head and blades, the outer edge of the cutter head is provided with a plurality of cutter grooves arranged along the circumferential direction, one blade is clamped in each cutter groove, each blade is a polygonal blade, and each side of each blade is sequentially provided with an auxiliary cutting edge, a first main cutting edge and a second main cutting edge. The auxiliary cutting edges on the two adjacent sides are connected with the second main cutting edge through a tool nose arc, the tool cutting edge angle of the first main cutting edge is alpha, the tool cutting edge angle of the second main cutting edge is beta, and alpha is smaller than beta. The cutting edge angles of the first main cutting edge and the second main cutting edge are set to be different, so that the first main cutting edge and the second main cutting edge form a broken line cutting edge, the cutting force on the unit cutting edge can be reduced, the cutt
