In figure: 1, ball knife ontology；2, blade；21, cutting edge；3, knife handle；4, frosting.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of bulk metal ceramics rose cutter, including blade 2 and knife handle 3, blade 2 and knife handle 3 are successively
Integrally connected, so as to form ball knife ontology 1, the mode of integrally connected reduces a possibility that being broken between blade 2 and knife handle 3.
Ball knife ontology 1 is cylindrical, and the blade 2 of integrally connected and knife handle 3 are made of cermet, and cermet both has metal
Toughness, high-termal conductivity and good thermal stability, and there is the high temperature resistant of ceramics, corrosion-resistant and wear-resistant etc. characteristics, thus
So that ball knife ontology 1 made of cermet has good rigidity, hardness and toughness, and can high temperature resistant, wear-resistant so that ball
Knife ontology 1 is provided with good cutting hardness, extends the service life of ball knife ontology 1.
Blade 2 is located at 1 one end of ball knife ontology, and the length of blade 2 is 1.5-2 times of 3 diameter of knife handle, so that blade 2
Length avoids reducing the toughness of milling cutter because blade 2 is too long while convenient for cutting, thus reduce a possibility that milling cutter breaks,
Further extend the service life of milling cutter.
2 surface of blade is mirror surface, and the periphery of the one end of knife handle 3 far from blade 2 is frosting 4, and rest part is mirror surface.
Mirror surface is the high embodiment of surface smoothness, and the milling cutter of mirror surface is finer, controllable in cutting；And frosting 4 is with uneven
Frosted sense, can increase fixture clamping milling cutter when frictional force, when avoiding milling cutter from processing with this generate vibration and offset, thus
Improve the cutting precision of cutter.
As shown in Figure 1 and Figure 2, blade 2 is equipped with cutting edge 21 far from one end of knife handle 3, and the first relief angle of blade 2 is 13 °-
16 °, the second relief angle is 20 ° -40 °, and apex angle is 1 ° -5 °.The present embodiment makes the more cutting edge of a knife or a sword of blade 2 using biggish first relief angle
Benefit reduces resistance when blade 2 is cut with this；And biggish second relief angle reserves enough spaces to clast when cutting, just
In the discharge of clast, play the role of good keeping away position；The setting of apex angle enables milling cutter gradually to be expanded outward when cutting by center
The area of cut, to avoid cutting at one time excessive and reduce the effect cut.
21 endpoint of cutting edge deviates 1 cross-section center 0.2mm-0.25mm of ball knife ontology, and the radian of cutting edge 21 is
18 ° -21 °, the reinforced partly wearability of 2 end of blade that 21 endpoint of cutting edge deviates, and lesser circular arc radian to cut
It is more sharp in cutting to cut sword 21, while being discharged convenient for clast, to accelerate cutting speed.
When the present embodiment is in use, the present embodiment during fabrication, need to only use numerically control grinder or numerical control machining center will
Molding cermet rod feed collet is tight, then cutting edge 21 is processed on bar by cutters such as grinding wheels, is finally repeatedly refined
?.Since cermet had not only had the toughness, high-termal conductivity and good thermal stability of metal, but also there is the resistance to height of ceramics
The characteristics such as warm, corrosion-resistant and wear-resistant so that ball knife ontology 1 made of cermet have good rigidity, hardness and
Toughness, and can high temperature resistant, wear-resistant so that ball knife ontology 1 is provided with good cutting hardness, extend making for ball knife ontology 1
Use the service life；And the length of blade 2 is 1.5-2 times of 3 diameter of knife handle, so that the length of blade 2 avoids while convenient for cutting
The toughness of milling cutter is reduced because blade 2 is too long, to reduce a possibility that milling cutter breaks, further extend milling cutter uses the longevity
Life.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
