Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-4, a high-speed dry cutting milling cutter comprises a cutter handle 1 and a cutter body 2, wherein the cutter body 2 is arranged on one side of the cutter handle 1, the high-speed dry cutting milling cutter further comprises a double-cutter groove 5, the cutter body 2 comprises a neck portion 8 and a blade portion 9, the cutter handle 1 is connected with at least one blade portion 9 through the neck portion 8, and the blade portion 9 is spirally arranged from the lower end of the cutter body 2 to the direction of the cutter handle 1 around the axis of the cutter body 2.

Specifically, the number of the cutting parts 9 is preferably four, the four cutting parts are spirally and uniformly distributed on one side of the neck part 8, through the arrangement of the four cutting parts 9, the rigidity of the cutter body 2 is good, the surface smoothness of a processed workpiece is good, the spiral angles of the cutting parts 9 can be equally divided or unequally divided, the equal-division spiral angle milling cutter is small in processing difficulty and low in manufacturing cost, and the unequal-division spiral angle milling cutters are different in spiral angle, so that the processing difficulty is increased, the manufacturing cost is high, and the vibration generated in the processing can be effectively reduced.

The inner side wall of the cutting part 9 is provided with a double-cutter groove 5, the outer side of the cutting part 9 is provided with a peripheral blade 10, the bottom end of the cutting part 9 is provided with an end blade 4, and the end blade 4 and the double-cutter groove 5 are provided with chip grooves 3.

In particular, by the arrangement of the chip flutes 3 and the double flutes 5, chips can be removed from the tool, and sticking of chips to the tool can be avoided.

Due to the arrangement, the chip removal mode of the milling cutter can be improved through the arrangement of the double cutter grooves 5, the phenomena of chip accumulation and cutter breakage are avoided, and the service life of the cutter is prolonged; the friction heat between the chips and the double cutter grooves 5 is reduced, the necessity of heat dissipation of special materials by cutting fluid during processing is reduced, and the milling cutter with the novel structure can be used for dry cutting of metals such as magnesium and the like.

Further, the double knife groove 5 is composed of a knife groove I6 and a knife groove II 7, the knife groove I6 is arranged to intersect with the side edge on the blade part 9, and the knife groove II 7 is arranged to intersect with the knife groove I6.
