Abstract

The utility model relates to a metal cutting cutter, in particular to a hard alloy milling cutter. The utility model is provided with a cutter body and a cutter handle. The cutter body is provided with a blade group; the cutting of any two blades of the blade group on the circumference is comprehensive; the appearance of the whole milling cutter is in corn cob shape; the cutting edge of two adjoining blades have a certain distance, which leads the contact surface between the cutting edge of each blade group and the workpiece to be reduced by about a half, and the contact surface between the whole milling cutter and the workpiece to be correspondingly reduced, thus reducing cutting force and cutting power efficiency of a machine tool.

Description

Carbide-tipped milling cutter

The utility model relates to a kind of metal cutting tool, particularly a kind of carbide-tipped milling cutter.

Carbide-tipped milling cutter in the market generally is made up of bite, cutter hub basis, handle of a knife, and bite is a carbide alloy, spiral elongated tool section, this milling cutter is because spiral elongated tool section is continuous, so exist the cutting edge contact-making surface big, cause cutting force big, and be difficult for the defective of reconditioning after forging a knife.

The purpose of this utility model is to propose a kind of carbide-tipped milling cutter that can solve above-mentioned shortcoming.

The purpose of this utility model is achieved in that a kind of carbide-tipped milling cutter, every tool section is made up of one group of granular screw type long blade of monolithic corn, be welded on the milling cutter body, adjacent two set of blades cross arrangements, guarantee that adjacent two set of blades cut containing on circumference, whole that the milling cutter outward appearance is corn is bar-shaped.

Because it is granular that the blade of each set of blades of the present utility model is all made corn, one distance is arranged between the cutting edge of adjacent two blades, the cutting edge and the workpiece contact-making surface of each set of blades have reduced about half when making cutting, whole the also corresponding minimizing of the contact-making surface of milling cutter and workpiece, thus cutting force reduced, and the cutting power of lathe reduces, be difficult for forging a knife, even forge a knife, only need single blade is repaired or changed, very convenient.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the rotation partial sectional view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the structural representation of another kind of mode of the present utility model.

As Fig. 1, Fig. 2, carbide-tipped milling cutter shown in Figure 3, have cutter hub 1 and handle of a knife 2 cutter hubs 1 are provided with screw type long blade group 3, set of blades 3 is made up of several blades and small blade 4.First blade that has one group in set of blades 3 two adjacent groups is big blade 5, and other blade all is small blades 4, cuts containing to guarantee the two adjacent groups blade on circumference.3 to 15 blades are generally arranged on a set of

blades

3,2 to 10 set of blades 3 are arranged on the milling cutter.

Be illustrated in figure 3 as another embodiment of the present utility model, screw type long blade group 3 is welded on the cutter hub 1, and cutter hub 1 is made cover shape 6, is enclosed within on the handle of a knife 2, can change cutter hub 1 easily like this.
