Abstract
A kind of cutter, including shank and cutting portion, shank include an accommodating cavity；Cutting portion includes the body and cutting end part that external diameter is 0.06mm~12mm, and body one end is fixed in accommodating cavity.The cutter of the present invention, suitable for using the reality manufacture of fabricated processing mode, being advantageous to shorten process time.
Description
Technical field
The present invention relates to a kind of instrument for being used to cut, more particularly to a kind of cutter, its cutting portion external diametrical extent to be
0.06mm~12mm, and be made up of superhard material.
Background technology
Precision cutting often uses small-diameter cutter (below 12mm, especially below 6mm), for the ease of dress in use
Cutter is pressed from both sides, small-diameter cutter often has the shank of a normal diameter (4mm, 6mm, 8mm, 10mm and 12mm), therefore typically
Small-diameter cutter is often stepped configuration.Meanwhile in order to keep the rigidity of cutter, often using complete hard alloy bar
Small-diameter cutter is manufactured by being ground, very small diameter cutting portion will be ground to bar one end of the external diameter same diameter of shank 20
10 (referring to Fig. 6), as the work department of cutter, it is very long to manufacture the time that such cutter is spent, human cost and equipment loss
Also it is higher.
In addition, when cutter is needed using the superhard material such as cermet, diamond and cubic boron nitride as blade, it is small straight
Footpath cutter can not be manufactured directly using above-mentioned material, otherwise boring cutter can only be fabricated to, the single-blade of lathe tool class freezes cutter (referring to figure
7), or coating can only be formed on Manufactured small-diameter cutter by coating process, i.e., in cutting edge made of hard alloy
Upper formation metal-cermic coating, diamond coatings or cubic boron nitride coating are all prior arts.But these coatings have commonly
Existing defects, such as：Coating its thickness there are about 0.002mm~0.01mm, and this causes cutting edge radius to have to increase
0.004mm~0.02mm, for precision cutting, the increase of radius of clean-up can greatly improve cutting resistance, can not only reduce quilt
Machined surface quality and cutter life can be reduced or directly fractureed；For another example：The adhesion of coating and blade is bad, particularly
Diamond coatings and cubic boron nitride coating, still the high-volume business application without maturation；And the cost of coated cutting tool is notable
Increase.
The content of the invention
It is an object of the present invention to provide a kind of cutter, its cutting portion external diameter is less than 12mm, especially less than 4mm,
And be made up of superhard material, and with cylinder class cutter structure more than complete 2 sword.
It is another object of the present invention to provide a kind of manufacture method of cutter, with realize be made up of hard material it is small straight
Footpath cutter, the processing (being ground to cutting end part diameter from shank diameter) to the big stock removal of shank bar is avoided, reduce manufacture
Cost, shorten the manufacturing cycle.
Cutter for machining field, such as：Aperture knife tool, milling cutter and boring cutter etc., its outward appearance is generally with overall presentation
Cylinder is relatively conventional, also with the feature such as cell body and cutting end part.From processing efficiency angle, these cutters typically have 2 pieces
Cutting edge above, cutting edge are also arranged at cutting end part more typically.
A kind of cutter provided by the invention, including
Shank, for the clamping of cutter, including an accommodating cavity；
Cutting portion, it includes body and cutting end part, and body one end is fixed in accommodating cavity.
The material of shank is hard alloy, steel or tungsten alloy, more than prioritizing selection tungstenic 60w/w% tungsten alloy.
Tungsten alloy contains one or several metals of iron, copper and mickel, is specially：Ferro-tungsten, tungsten-copper alloy and tungsten nickel
Etc. high specific gravity high density tungsten alloy.These tungsten alloys are also containing one or more of metals such as chromium, manganese and cobalts, but be not Tool Industry
In be used to process the hard alloy of blade.
The external diameter of body is 0.06mm~12mm, especially less than 0.06mm~4mm, and the material of use is such as：Hard alloy,
Cermet, man-made polycrystalline diamond and cubic boron nitride.
Bulk material is the one or more of man-made polycrystalline diamond, hard alloy, cermet and cubic boron nitride.
Cutting end part is cylindric, and material is such as：Man-made polycrystalline diamond, hard alloy, cubic boron nitride and cermet
One or more, or man-made polycrystalline diamond is mutually compound with hard alloy and obtains.
The length of the body one end being arranged in accommodating cavity is the 15%~85% of body total length, prioritizing selection 25%~
60%, such as：But 25%, 30%, 33%, 35%, 40%, 45%, 50%, 55% and 60% is not limited only to, is arranged at accommodating cavity
The external diameter of interior body one end is 0.06mm~12mm, prioritizing selection 0.1mm~10mm.
In order to produce the various small-diameter cutters of the present invention, the manufacture method of a kind of cutter that the present invention also provides, including：
Superhard material column is produced, then the column one end is fixed in the accommodating cavity for being arranged on shank, then
Column and shank are processed on demand as an entirety, form external diameter, cell body, land and cutting edge, the shape on column
Into cutting end part.
The method for obtaining superhard material column is entered including electric discharge wire cutting or laser cutting device to superhard material
Row cutting, either centerless grinder or cylindrical grinder superhard material is carried out grinding or by superhard material directly into
Type sinters to obtain.
Interior cold hole is also opened up on shank.
For fixed method such as：Interference fit, vacuum freeze and freezed with high frequency.Realize the mode of interference fit such as：
Utilize low temperature or high temperature so that material shrinkage or heat expansion, after cutting portion assembles with accommodating cavity, then reply normal temperature realization.
The method processed on demand is such as：Laser Processing, ultrasonic grinding, mechanical grinding, electric discharge wire cutting and electric discharge grinding etc..
The beneficial effect that technical solution of the present invention is realized：
The cutter of the present invention, suitable for using the reality manufacture of fabricated processing mode, it is no longer necessary to carried out to shank section
Substantial amounts of grinding, be advantageous to shorten the manufacturing time of cutter, while shank is hard using the strong steel of machinability or tungsten alloy replacement
Matter alloy, it is comprehensive to save material cost, processing cost and process time.
Tool in Cutting performance and Tool in Cutting portion relation are larger, therefore cutting portion uses the superhard matter with high rigidity high rigidity
Material, the minor diameter cutting tool not yet occurred at present using complete superhard material as cutting portion is realized, it is whole by cutting portion
Body be superhard material (i.e.：Cermet, diamond and cubic boron nitride etc.) mode, make cutter life than ever
Hard alloy cutter and coated cutting tool more than 1 times of increase.
