Specific implementation mode
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings and pass through
Specific implementation mode further illustrates the technical solution of the utility model.
A kind of milling cutter is present embodiments provided, as depicted in figs. 1 and 2, which includes handle of a knife 1 and milling portion 2, the milling
It includes several spaced blades 3 to cut portion 2, and the gap between the adjacent blade 3 forms knife core, and the knife core includes
First knife core 31 and the second knife core 32, the first knife core 31 and the second knife core 32 by the milling portion 2 front end backward
End sets gradually and is connected to, and the area of section of the first knife core 31 is not more than the area of section of the second knife core 32,
In, the arrow direction in Fig. 1 is that the direction of rear end is directed toward in the front end in milling portion 2.
The present embodiment is by setting the knife core in the milling portion 2 of milling cutter to spaced first knife core 31 and the second knife core
32, and the area of section of the first knife core 31 and the second knife core 32 differs so that knife core becomes core setting, in the process of workpieces processing
In, since the area of section of the first knife core 31 is not more than the area of section of the second knife core 32 so that the second knife core 32, which is conducive to hold, considers to be worth doing,
The area of section of first knife core 31 is less than normal, is on the one hand conducive to hold bits, while can improve the rigid of cutter entirety again, extend
Cutting-tool's used life.
