Abstract

The invention relates to an efficient high-speed cutting hard alloy milling cutter, comprising a cutter body and a cutter handle, wherein the cutter body comprises four groups of blades and four groups of chip removal slots; the blades and the chip removal slots are spirally arranged; the chip removal slots are arranged between the two adjacent blades; the junction of the end blades of one group of symmetrical blades is provided with a groove; and the end blades of the other group of symmetrical blades are connected. The efficient high-speed cutting hard alloy milling cutter has the advantages that: the end blades are provided with the grooves; when the efficient high-speed cutting hard alloy milling cutter is used for machining, scrap iron can flow into the chip removal slots from the groove; the chip removal capability in the machining process is improved, the end blades of the blades are free from sticking chips, the cutter is guaranteed to normally use, the cutting capability is improved, and the service life is prolonged.

Description

A kind of efficient high-speed cutting carbide-tipped milling cutter

Technical field

The present invention relates to a kind of machining equipment, be specifically related to a kind of efficient high-speed cutting carbide-tipped milling cutter.

Background technology

Milling cutter is to be used for rotary cutter Milling Process, that have one or more cutters tooth, and existing milling cutter comprises handle of a knife, cutter hub, cutter tooth and chip area composition, and the cutter hub of handle of a knife one end is provided with several cutters tooth and chip area; Discharge launder is arranged between the two adjacent cutters tooth, and cutter tooth and chip area shape in the shape of a spiral are arranged on the cutter hub, and its several cutters tooth are arranged on the cutter hub with chip area with identical helical angle symmetrically; Because cutter tooth end sword does not have chip area, is adding man-hour, adds man-hour as not adding cooling fluid; Be prone to cause the blade chip removal not smooth, cutter tooth end sword is prone to sticking bits, causes the tool wear aggravation; Cutting power descends, thereby influences milling cutter service life.

Summary of the invention

It is not smooth that the technical problem that the present invention will solve is that milling cutter adds the chip removal in man-hour, and cutter tooth end sword is prone to problems such as sticking bits, improves a kind of efficient high-speed and cut carbide-tipped milling cutter.

In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: a kind of efficient high-speed cutting carbide-tipped milling cutter, comprise cutter hub, handle of a knife, and said cutter hub comprises four groups of blades, four groups of chip areas; Said blade, the equal helical layer shape of chip area are arranged; Said chip area is arranged between the two adjacent blades, and the end sword junction of said one group of symmetry blade has groove, and the said end sword that another organizes symmetrical blade links to each other.

Preferably, the helical angle of said blade is 55 °, helical angle and cutting resistance, anterior angle, machined surface precision, and cutter life is all relevant, and helical angle is 55 ° and is one embodiment of the invention.

Preferably, the roughness of said blade, handle of a knife is 0.2 μ m, and the roughness of chip area is 0.4 μ m, and the microcosmos geometric shape characteristic that less spacing that roughness refers to have on the finished surface and peak valley are formed has determined the process of handle of a knife and chip area.

Preferably, said cutter hub and handle of a knife integral manufacturing, but also can for as structure such as the tooth-like indexing type of whole weldering, integral manufacturing is convenient and simple, Practical Performance is good.

Preferably, said cutter hub, handle of a knife adopt carbide alloy, also can process for other cutter materials, and carbide alloy has the hardness height, thermohardening is good, wearability is good, intensity is high, corrosion-resistant premium properties such as good.

In sum, advantage of the present invention: through having groove on the end sword, adding man-hour, iron filings can flow into chip area through groove; Make in the process, the chip removal ability improves, and the end sword of blade does not have sticking bits phenomenon; Guaranteed that cutter normally uses, improved cutting power, improve service life.

Description of drawings

Below in conjunction with accompanying drawing the present invention is described further:

Fig. 1 is a kind of efficient high-speed cutting of the present invention carbide-tipped milling cutter front view;

Fig. 2 is a kind of efficient high-speed cutting of the present invention carbide-tipped milling cutter right view;

Fig. 3 is the partial enlarged drawing of III among Fig. 2.

The specific embodiment

Embodiment one:

Like Fig. 1, Fig. 2, shown in Figure 3, a kind of efficient high-speed cutting carbide-tipped milling cutter comprises cutter hub 1, handle of a knife 2; Said cutter hub 1 comprises four groups of blades 3, four groups of chip areas 4, said blade 3, chip area 4 all in the shape of a spiral shape arrange, said chip area 4 is arranged between the two adjacent blades 3; The end sword junction of said one group of symmetry blade 3 has groove 5, and the said end sword that another organizes symmetrical blade 3 links to each other, and the helical angle of said blade 3 is 55 °; Helical angle and cutting resistance, anterior angle, processed precision, cutter life are all relevant, and 55 ° of helical angles are a kind of embodiment of this practicality, and the roughness of said blade 3, handle of a knife 2 is 0.2 μ m; The roughness of chip area 4 is 0.4 μ m; The microcosmos geometric shape characteristic that less spacing that roughness refers to have on the finished surface and peak valley are formed has determined the process of handle of a knife 2 with chip area 4, said cutter hub 1 and handle of a knife 2 integral manufacturings; But also can for as structure such as the tooth-like indexing type of whole weldering; Integral manufacturing is convenient and simple, and Practical Performance is good, and said cutter hub 1, handle of a knife 2 adopt carbide alloy; Also can process for other cutter materials, carbide alloy has the hardness height, thermohardening is good, wearability is good, intensity is high, corrosion-resistant premium properties such as good.

Embodiment two:

Like embodiment one described a kind of efficient high-speed cutting carbide-tipped milling cutter, present embodiment has following difference, and the helical angle of said blade is 30 °.

On the correct main shaft of installing with milling machine of the handle of a knife of milling cutter 2, guarantee that the cutter hub 1 of milling cutter does not rock, adding man-hour; When blade 3 carried out the milling workpiece, the groove 5 that the iron filings on the workpiece can go out out through the end sword of blade 3 flowed out, and discharges through chip area 4; Make in the whole machining process process; The assurance iron filings are normally discharged, and during cutting, need not to add cooling fluid.

In sum, through having groove on the end sword, adding man-hour, iron filings can flow into chip area through groove, make in the process, and the chip removal ability improves, and the end sword of blade does not have sticking bits phenomenon, has guaranteed that cutter normally uses, and has improved cutting power, and improve service life.
