Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As depicted in figs. 1 and 2, the present invention provides a kind of cemented carbide profile milling cutter, including knife handle 1 and tool tip 2, described
Knife handle 1 and the tool tip 2 are integrally formed.The tool tip 2 is in fir tree shape, to be formed with multiple protrusions in tool tip 2
22 and groove 21.Multiple mounting hole (not shown)s are offered in fir tree shape tool tip 2, and are installed in this mounting hole
There are the hard alloy cutter tooth being made of multiple first blades 31, the second blade 32 and third blade 33, this hard alloy cutter tooth
Anterior angle angular range be 0 °~20 °.The structure of first blade 31, the second blade 32 and third blade 33 is all different,
And offer connecting hole (not shown) on first blade 31, the second blade 32 and third blade 33, by
Fastening screw (not shown) is installed the first blade 31, the second blade 32 and third blade 33 are spirally connected and are mounted in connecting hole
In mounting hole.Wherein the first blade 31 is distributed along front of motor to the connecting pin of tool tip 2, and is installed in the convex of tool tip
On rising.Second blade 32 is mounted in the groove 21 of the tool tip 2, and is respectively mounted in each groove 21 there are two portion
Divide the second blade 32 of juxtaposition setting.Wherein close to being equipped with third in this groove 21 of tool tip 2 and 1 junction of knife handle
