Abstract

The utility model relates to a milling cutter for finishing and cutting a hard alloy with high efficiency and high speed, comprising a cutter body and a cutter handle, wherein the cutter body comprises at least two groups of cutting edges and at least two groups of chip removal grooves; the cutting edges and the chip removal grooves are spirally arrayed; the chip removal groove is disposed between the two adjacent cutting edges; and at least one spiral groove is disposed along the rotation direction of the chip removal groove in each chip removal groove. The milling cutter for finishing and cutting a hard alloy with high efficiency and high speed disclosed by the utility model has the following advantages that: spiral grooves are disposed on the chip removal grooves, so that iron chips can be discharged from the chip removal grooves via the spiral grooves while machining, thereby enhancing chip removal capacity during the machining process; and a chip adhesion phenomenon is avoided at the end edge of the cutting edge, thereby ensuring the normal use of the cutter, enhancing the cutting capacity and increasing the service life thereof.

Description

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

Technical field

The utility model relates to a kind of machining equipment, is specifically related to a kind of efficient high-speed fine finishining 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; Adding man-hour; As when adding cold cut liquid invariably, be prone to cause the blade chip removal not smooth, cause the tool wear aggravation; Cutting power descends, thereby influences milling cutter service life.

The utility model content

The technical problem that the utility model will solve is that milling cutter adds the not smooth problem of chip removal in man-hour, improves a kind of efficient high-speed fine finishining cutting carbide-tipped milling cutter.

In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of efficient high-speed fine finishining cutting carbide-tipped milling cutter; Comprise cutter hub, handle of a knife, said cutter hub comprises at least two group blades, at least two group chip areas, and said blade, chip area be shape arrangement in the shape of a spiral all; Said chip area is arranged between the two adjacent blades, is provided with at least one helical groove along the chip area direction of rotation in the said chip area.

Preferably, the helical angle of said blade is 30 °, helical angle and cutting resistance, anterior angle, machined surface precision, and cutter life is all relevant, and helical angle is 30 ° and is an embodiment of the utility model.

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, the advantage of the utility model:, adding man-hour through having helical groove on the chip area; Iron filings can be discharged chip area through helical groove, make in the process, and the chip removal ability improves; 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 fine finishining cutting of the utility model carbide-tipped milling cutter front view.

The specific embodiment

Embodiment one:

As shown in Figure 1, a kind of efficient high-speed fine finishining 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; Be provided with at least one helical groove 5 along chip area 4 direction of rotation in the said chip area 4, the helical angle of said blade 3 is 30 °, and helical angle and cutting resistance, anterior angle, processed precision, cutter life are all relevant; 30 ° 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, and 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, Practical Performance is good; 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, because groove 5 is very little; People can not detect by an unaided eye, and need use magnifying glass and observe and could observe.

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 iron filings on the workpiece can flow out through the helical groove 5 that has in the chip area 4, discharge through chip area 4; Make in the whole machining process process; The assurance iron filings are normally discharged, and add man-hour, need not to add cooling fluid.

Embodiment two:

Like embodiment one described a kind of efficient high-speed fine finishining cutting carbide-tipped milling cutter, present embodiment has following difference, and the helical angle of said blade is 55 °.

In sum, through having helical groove on the chip area, adding man-hour, iron filings can be discharged chip area through helical 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.
