In the such scheme: this cutting blade more comprises one first side knife surface and one second side knife surface, this first side knife surface is the side face between this first side edge and this second side edge, it is planar to be circular arc, this second side knife surface is the side face between this second side edge and this side tool back of the body, it is planar to be circular arc, and the arc radius of this second side knife surface is greater than this first side knife surface, so that the side face of this cutting blade is double-deck step shape.Be formed with a shallow chip removal groove on this first side knife surface, this shallow chip removal groove is along this second side edge lower edge moulding, and the degree of depth is shallow than this chip removal groove.
This milling cutter more comprises: one first end sword, and be located at the end of a bite sword, and be formed at a wherein side channel limit of a chip removal groove ends; One second end sword is located at the end of another cutting blade, and is formed at a side channel limit of another chip removal groove ends, and this second end sword and this first end sword are a straight line; One first end knife face is by the low backward oblique angle of this first end sword; And one second end knife face, by the low backward oblique angle of this second end sword, and the low tilted direction of this second end knife face is opposite with this first end knife face.
This milling cutter more includes the one first end knife back and the second end knife back, and this first end knife back hangs down oblique one bigger angle backward by this first end knife face, and this second end knife back hangs down oblique one bigger angle backward by this second end knife face.
Compared with prior art, the beneficial effects of the utility model are: the utility model milling cutter is when the rotation milling, this first side edge just can be rough milled workpiece earlier and cut, this second side edge also can then be cut as finish-milling this workpiece subsequently, and make the feed each time of this milling cutter all can finish simultaneously to rough mill and cut and effect that finish-milling is cut, and then can therefore significantly promote the operating efficiency that milling is processed, and since this rough mill cut with the finish-milling cutting not performed by this first side edge and second side edge, the service life of this milling cutter that therefore then more can increase substantially.
