Abstract
The utility model discloses a milling cutter with high hardness and high wear resistance. The milling cutter comprises a cutter bit part and a cutter rod part, wherein the cutter bit part and the cutter rod part adopt an integrated structure; a hard wearproof coating of aluminium oxide is arranged on the outer surface of the cutter bit part; a first hard wearproof coating of titanium nitride or titanium silicide is arranged on the outer surface of the hard wearproof coating of aluminium oxide; a hard wearproof coating of chromium nitride or chromium silicide is arranged on the outer surface of the hard wearproof coating of the first hard wearproof coating of titanium nitride or titanium silicide; a second hard wearproof coating of titanium nitride or titanium silicide is arranged on the outer surface of the hard wearproof coating of chromium nitride or chromium silicide. Through the manners, the milling cutter has higher hardness, better wear resistance and better heat resistance.
