Abstract
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of novel milling cutter is provided, and it is rational in infrastructure, and chip removal is convenient, and process velocity is fast, low cost of manufacture, the novel milling cutter of long service life.Compared with prior art, its remarkable advantage is the utility model: the utility model is rational in infrastructure, easy to process, manufacturing cost is lower, by offer groove on end sword, make iron filings enter chip area by groove, chip removal is convenient and reliable, without sticky bits phenomenon, adopt the chamfered teeth being formed by first jiao, second jiao and triangle, simplified the structure of angle cutting tool, improved process velocity, this long product lifecycle, realistic instructions for use.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of milling cutter.
Background technology
At present, most of milling cutter function singleness, in process, blade chip removal is not smooth, and cutter tooth end sword is sticky bits easily, thereby cause tool wear aggravation, and cutting power declines, and shorten service life.In addition, because will use bolt, so need to arrive base counterbore, often speed is slower for the processing of counterbore for existing cutter, and efficiency is not high, and left and right moment of torsion is many, causes shorten the service life of cutter.Angle cutting tool is used for milling out chamfering, in the processing for common aluminum alloy material, and conventional high accuracy, the complex structure of high rotating speed angle cutting tool, manufacturing cost is high, does not meet actual operation requirements.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of rational in infrastructure, and chip removal is convenient, and process velocity is fast, low cost of manufacture, the novel milling cutter of long service life.
Technical scheme: in order to solve the problems of the technologies described above, the novel milling cutter of one described in the utility model, it comprises cutter hub, and the handle of a knife of connection cutter hub, be provided with oil supply slotted eye on described handle of a knife top, they are all one-body molded, described cutter hub is by four groups of spiral cutting edges, four groups of helical flute compositions, the even interval of described spiral cutting edge and helical flute arranges, two spiral cutting edge front portions are in the same horizontal line provided with groove, be provided with chamfered teeth in two other spiral cutting edge front portion, described chamfered teeth comprises first jiao, be located at first jiao other second jiao, and be arranged on second jiao of other triangle, described first jiao is 10 °, second jiao is 15 °, triangle is 30 °.
The spiral angle of described spiral cutting edge and helical flute is between 35-55 °.
Described cutter hub and handle of a knife are all cylinder.
Described cutter hub is carbide alloy cutter hub.
Described handle of a knife is carbide alloy handle of a knife.
Beneficial effect: compared with prior art, its remarkable advantage is the utility model: the utility model is rational in infrastructure, easy to process, manufacturing cost is lower, by offer groove on end sword, make iron filings enter chip area by groove, chip removal is convenient and reliable, without sticky bits phenomenon, adopt the chamfered teeth being formed by first jiao, second jiao and triangle, simplified the structure of angle cutting tool, improved process velocity, this long product lifecycle, realistic instructions for use.
Brief description of the drawings
Fig. 1 is planar structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of chamfered teeth described in the utility model.
Detailed description of the invention
Below by drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, the novel milling cutter of one described in the utility model, it comprises cutter hub 1, and the handle of a knife 2 of connection cutter hub 1, be provided with oil supply slotted eye 3 on described handle of a knife 2 tops, they are all one-body molded, described cutter hub 1 is by four groups of spiral cutting edges 4, four groups of helical flutes 5 form, the even interval of described spiral cutting edge 4 and helical flute 5 arranges, two spiral cutting edge 4 front portions are in the same horizontal line provided with groove 6, be provided with chamfered teeth 7 in two other spiral cutting edge 4 front portions, described chamfered teeth 7 comprises first jiao 8, be located at first jiao 8 other second jiao 9, and be arranged on second jiao of 9 other triangle 10, described first jiao 8 is 10 °, second jiao 9 is 15 °, triangle 10 is 30 °, the spiral angle of described spiral cutting edge 4 and helical flute 5 is between 35-55 °, described cutter hub 1 and handle of a knife 2 are all cylinder, described cutter hub 1 is carbide alloy cutter hub, described handle of a knife 2 is carbide alloy handle of a knife.The utility model is rational in infrastructure, easy to process, manufacturing cost is lower, by offer groove on end sword, make iron filings enter chip area by groove, chip removal is convenient and reliable, without sticky bits phenomenon, adopts the chamfered teeth being made up of first jiao, second jiao and triangle, simplify the structure of angle cutting tool, improve process velocity, this long product lifecycle, realistic instructions for use.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
