Abstract
The utility model proposes a kind of diamond superhard cutter of superior performance, it comprises hard metal matrix, mainly carbide alloy or steel matrix, there is two or more cutting edges, described cutting edge is made up of diamond superhard material, it is characterized in that: the rear knife face place of each cutting edge described have through polishing and the curved surface of roughness between 0.003-0.19 μm, and there is the little relief angle of cutting edge, the angle of described little relief angle is 15-19 °; This cutter also has chip area and shock absorption strip simultaneously.It is easy, simple and reliable for structure that the utility model realizes, there is the problem of chipping in the conventional PCD superhard cutter sword face out-of-flatness solved, cutting edge, solve in tool sharpening process and vibrate obvious problem, serve the effect improving workpiece quality and tool life.
Description
Technical field
The utility model relates to a kind of machining tool, particularly a kind of diamond superhard cutter of superior performance.
Background technology
All there is diamond ultra hard material layer on the surface of existing diamond superhard cutter, this make as processing metal, nonmetal, there is excellent anti-wear performance, such as diamond superhard cutter just has superior wearability when processing the material such as silumin, graphite, and its wearability is more than 10 times of common coated cutting tool.But under microstate, the rugged state of surface presentation of diamond ultra hard material layer, causes that diamond ultra hard material layer surface is more coarse, there are the defects such as chipping in sword face; Meanwhile, bar-shaped rotary cutter can produce larger vibration adding man-hour, and these problems above-mentioned all can cause processed workpiece surface finish not high, also have impact on the service life of cutter itself.Very limited for the existing method effect overcoming above-mentioned defect, and the diamond superhard cutter that current market also not yet has new construction can solve the problem well.
Utility model content
The utility model proposes a kind of diamond superhard cutter of superior performance, it has unique structural design, solve conventional PCD superhard cutter due to the problem that the surface of diamond ultra hard material layer is more coarse, there are the defects such as chipping in sword face, also solve because of the not high problem of the machining accuracy of vibration cutting generation simultaneously.
The technical solution of the utility model so realizes:
A kind of diamond superhard cutter of superior performance, such as drill or milling cutter etc., it comprises hard alloy substrate, has two or more cutting edges, described cutting edge is made up of diamond superhard material, for diamond ultra hard material layer, the rear knife face place of each cutting edge described have through polishing and the curved surface of roughness between 0.003-0.19 μm, described cutting edge has little relief angle θ, and described little relief angles is 15-19 °.According to the repeatedly practice of applicant, best results when diamond ultra hard material layer is cvd diamond film.The surface roughness of polishing and the angle-data of little relief angle are all repeatedly put into practice by applicant the result drawn, all can reach technique effect more obvious than prior art progress.
Preferably, described hard alloy substrate can be Steel material or WC/Co carbide alloy.
Preferably, each cutting edge described also has corresponding chip area.
Preferably, described rear knife face has elongated lanyard.
The process of the utility model back of the body knife face polishing is supplemented and is described below: equipment used and material comprise polishing machine, polishing material uses polishing wheel and antiscuffing paste, and polishing wheel selects wool polishing wheel, diameter 200mm, thick 15mm; Diamond polishing cream selected by antiscuffing paste, and Buehler imported with original packaging MetaDi diamond mixes blue polishing fluid, MetaDi
tMdiamond mixing suspension, it is the mixing suspension that monocrystalline silicon diamond adds intermixture, diamond grain size distributes closely, without the need to diluting again during use, can directly use, be more suitable for Burst polishing fluid delivery system to use, be widely used in except the grinding/polishing to the various material samples except water sensitive.
During polishing, from diamond superhard cutter from the rear knife face of blade to knife edge polishing, so namely can ensure the sharp of cutting edge after polishing, can ensure again can not cause secondary injury to cutting edge in polishing process.After noting diamond superhard cutter before polishing during clamping, knife face and wool are taken turns tangent, ensure that tangent line is near cutting edge as far as possible.Wool wheel speed 50-150r/min, must ensure to stablize during wool wheel clamping, rotation process can not rock.Then polishing fluid is evenly coated on polishing wheel, then cutter clamping is carried out polishing on polishing machine.
The chip area of the correspondence that each cutting edge of the present utility model also has, the detritus that described chip area can make machining stay disconnects in time and leaves cutter.Reduce the impact of detritus on cutter and workpiece.
The rear knife face of each cutting edge of the present utility model has elongated lanyard, and this lanyard to become band distribution along knife edge, and its effect reduces drill or milling cutter radial vibration, thus reduce the error of machining accuracy.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the utility model cutting edge local visual figure I;
Fig. 3 is the utility model cutting edge local visual figure II;
Reference numeral in figure:
1. hard alloy substrate, 2. cutting edge, 3. diamond ultra hard material layer, 4. rear knife face, 5. chip area, 6. lanyard
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of diamond superhard cutter of superior performance, comprise hard alloy substrate 1, there is two or more cutting edges 2, described cutting edge has diamond ultra hard material layer 3 on the surface, rear knife face 4 place of each cutting edge described have through polishing and the curved surface of roughness between 0.003-0.19 μm, described cutting edge has little relief angle θ, and described little relief angles is 15-19 °.This technical scheme can reduce the harmful effect brought when the out-of-flatness of diamond microstructure and cutting edge exist chipping.
Preferably, described hard alloy substrate can be Steel material or WC/Co Hardmetal materials layer.
Preferably, the chip area 5 of the correspondence that described each cutting edge also has, the detritus that described chip area can make machining stay disconnects in time and leaves cutter.Reduce the impact of detritus on cutter and workpiece.
Preferably, the rear knife face of described cutting edge has elongated lanyard 6, the effect of lanyard is vibration when reducing tool sharpening, improves Workpiece Machining Accuracy.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model.To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
