Natural diamond (ND) tool
As natural diamond peak pulling vines, has got the following characteristics:
(1) tip-1332, the display is diamond.
(2) wave-amplitude (FWHM) is 4.1 CM - 1
Display like a solid diamond. It really is currently known mineral ND hard material, primarily accustomed to prepare the Knife tool. Natural diamond tool Fine milled edge radius of 0.01 to 0.002 Î¼m. One single crystal natural diamond (Single Crystalline Diamond SCD) tool, knife edge site by high-magnification observation still 1500 times the sides smooth. SCD turned aluminum piston Ra when nearly 4 Î¼m, possibly at the same cutting conditions PCD tool used when processing the surface roughness of 15 to 50 for Ra Î¼m. It really is in combination with precision lathe tool SCD precision and ultra-precision machining, you will get mirror-like surface.
Poly-crystal diamond tool (PCD)
High-Temperature PCD is under conditions including the cobalt metal, diamond powder is sintered synthetic gathered in excess of the single crystal materials, also called sintered diamond. Poly-crystal diamond tool overall burn, forming a trimmer for the trimming process, PCD die isn't any chronological order status, the isotropic case, hardness, and in some cases the temperature of graphite C 550 Âбу. The tool carries a high hardness, high thermal conductivity, low thermal expansion coefficient, high coefficient of elasticity plus a low coefficient of friction. There're very sharp.
Synthetic poly-crystal diamond compound (PDC) tool
In order to enhance the resilience and PCD blade may be welded, often with tungsten carbide knives PCD will probably be produced in man-made poly-crystal diamond composite blade (PDc). In the cemented carbide substrate the symptoms layer suppressed a 0.5 to 1 mm thick PCD sintered. Composite blades from the flexural strength and tungsten carbide, hardened, and you may all-around PCD PCD alternative use. Joining together PCD and man-made crystal diamond compound (PDC) tool from the cutting edges sharp along with the processing from the surface of the workpiece in poor ND . It may be processed simultaneously, sanding than small, and hard to head any shape of geometry. Are now using synthetic poly-crystal diamond composite films are only able to be manufactured, the knife still is not useful for making grooves while using the scraps in the turnover and complex 3d surface geometry with the cutter.
Diamond CVD thick film (TDF) soldering tool
thick-film diamond soldering tool is the laser cut out thick-film Diamond CVD a welded towards the base product (commonly a K class carbide), an amalgamated, and then polished composite chip, 2 body from the tool towards welding, cutting, grinding with a desired shape and cutting edges. As shown in Figure 3 (A) shown below, for CVD diamond thick film (diamond film thickness as high as 30 Î¼M), carries a high hardness, abrasion resistance, low friction coefficient, manufacturing cutting non-ferrous metals and non-metallic materials inside the tool ideal materials. Since diamond welding process process complex, CVD diamond thick film (TDF) soldering tool is not high volume applications.
Diamond-coated tool
Diamond-coated tool using law CVD K directly in tungsten carbide (for example tungsten carbide or ceramic substrate deposited over a level 1 to 25 Î¼m diamond thin films,-ag-isotropic. As shown in Figure 3 (B). Film-coated tool hardness approximately ~10,000 HV 9800. High thermal conductivity, thermal conductivity at room temperature approximately 2000, Mr. W K m-1, -1, and carbide cutters conductivity is merely 80 to 100 M - 1 Âбд K -1. Diamond CVD method could be given to any complex shape within the tool, which is owned by crystal diamond isn't the most critical advantages.
cubic boron nitride (PCBN tool )
cubic boron nitride (PCBN) is really a synthetic diamond will be the second form of inorganic Ultra hard materials, the hardness of the diamond, heat stability, and effectiveness against heat 1400 ~ 1500, Diamond's effectiveness against heat (700 to 800 degrees) is practically two times as high, cubic boron nitride (PCBN) tool mainly employed for processing of ferrous metals and their alloys material; the most suitable for a number of hardened steel, carbon steel bearing steel mold steel high-speed steel, pearl-gray certain is certain, titanium, vanadium cold, hard cast iron hot temperature alloys, cobalt-nickel-base alloys, alloy) and surface coating with the welding process with durability, reduced amount of tool changes to compensation down some time it will require for CNC machine tools and automated production line of high-performance full play, you can change the traditional machining methods (i.e. , rough hardened tool used pre and post quenching the emery wheel refinishing methods) so that you can numerically controlled machine tools in the hardened after quenching prior to the cutting processing ( As mill), and still have an excellent economic benefits.
