Embodiment
Further illustrate specific embodiment of the present utility model below in conjunction with the accompanying drawings.
Composite milling cutter provided by the utility model, including cutter head 1, cutter head 1 have the first cutting portion 2 and the second cutting portion 3.
Wherein the first cutting portion 2 has at least two first cutters tooth, and tail end of first cutter tooth from the end of cutter head 1 toward composite milling cutter is in spiral shell
Spin line is set.Specifically, the blade of the first cutter tooth is made up of end sword with side edge, and the end sword 21 of the first cutter tooth is located at the end of cutter head 1
Portion, the end sword 21 of the first cutter tooth are in the arc-shaped of evagination, and the side edge 22 of the first cutter tooth is located at end and the second cutting portion of cutter head 1
Between 3, the side edge 22 of the first cutter tooth is linearly.Coaxially to each other, the second cutting portion 3 has for second cutting portion 3 and the first cutting portion 2
There are at least two second cutters tooth, the side edge 31 of the second cutter tooth is in the arc-shaped of evagination, and the side edge 31 of the second cutter tooth is along compound milling
The blade for radially exceeding the first cutter tooth of knife.
