Natural diamond (ND) tool
Vines for diamond peak, that has this characteristics:
(1) spike shows we have a diamond.
(2) the wave amplitude (FWHM) 4.1cm-1
Looks like a pure diamond. ND is the hardest known mineral substances, mainly used in the preparation of Cutter tool. As soon as the fine grinding of natural diamond cutter edge radius all the way to 0.01~0.002μm.
Natural single crystal diamond (Single Crystalline Diamond,SCD) technologically advanced part of the tool power 1500 times times however to the edge smooth. SCD turning of aluminum piston Ra can reach 4μm, and within the same cutting conditions using PCD tool when machining the outer lining roughness of Ra for 15~50μm. SCD tool along with precision and ultraprecision machining precision lathe, mirror surface can be purchased.
Polycrystalline diamond (PCD) tool
PCD adopted under conditions of heat and super high pressure cobalt gathered metal bond diamond powder sintered polycrystalline materials synthesis, generally known as sintered diamond. Whole sintering of  polycrystalline diamond tool cutter, milling, grain is a random arrangement of PCD are isotropic, uniform hardness, graphitization temperature of 550 ° c. Tool rich in hardness, high thermal conductivity, low thermal expansion coefficient, low coefficient of friction and high elastic modulus. Blade is quite sharp and many others.
Artificial polycrystalline diamond compact (PDC) tool
To enhance PCD blade toughness and weldability, PCD and carbide knives created from artificial polycrystalline diamond composite Blade (PDc). Cemented carbide substrate with pressed 0.5~1mm thick layer on its surface formed by sintering PCD. Flexural strength of composite blades with carbide, hardness all around PCD, can be an option to PCD. PCD and artificial polycrystalline diamond compact (PDC) tool for sharp edges and processing on the workpiece surface quality than ND. At the same time their poor machinability, grinding than small, difficult under the geometric form of the head. Currently using artificial polycrystalline diamond composite preparation tool are only able to still is not made indexable blade with chip breaker grooves and complex 3
dimensional surface geometry milling cutters.
CVD diamond thick film (TDF) welding tool
Welding of diamond thick film cutting tools are good CVD diamond thick film laser cut welded on the substrate (typically cemented carbide for your k class), occurance of PDC and polishing compound, welded to the body for the second time, grinding into your required shape and cutting edge. Figure 3 (a) below, and to CVD diamond thick films (diamond-like carbon film thickness up to 30μm), with good hardness, wear resistance, low friction characteristics, is good material for cutting non-ferrous metal and non-metal tool manufacturing. As a consequence of diamond welding technology complex, CVD diamond thick film (TDF) welding tool has not been high-volume applications.
Diamond coated cutting tools
Diamond-coated tools are directly inside the cemented carbide by CVD method (k form of cemented carbide) or
1~25μm Diamond-like carbon films deposited with a ceramic substrate layer, no cleavage surface of isotropic.
Figure 3 (b). Thin film coating tool hardness nearly 9800~10000HV. High thermal conductivity, thermal conductivity at room temperature approximately 2000W · m-1 · K-1, thermal conductivity only cemented
80~100m-1 · K-1。 CVD diamond coated tool on any complex shapes, the majority of this can be PCD cannot have significant advantages.
Cubic Boron Nitride (PCBN) tool
Cubic nitride boron (PCBN) is following artificial synthesis diamond zhihou appears of second species inorganic super hard material, its hardness slightly times Yu diamond, hot stability good, heat sexual can
reached 1400~1500du, than diamond of heat sexual (700~800du) almost high 1 time times. cubic nitride boron
(PCBN) tool main for processing various ferrous metals and alloy material; most for Yu various quenching hard steel (carbon pigment tools steel bearing steel die steel high speed steel) Pearlite ash mouth certain
(vanadium titanium surefire) Chilled surefire high temperature alloy (nickel base alloy cobalt base alloy) as well as the surface spray heap welding of processing. has using extremely deep seated, reduced for knife
number, compensation downtime by spent of your energy, makes NC machine and Automation type of efficient can will be more full of play, may change traditional of machinery processing way (is quenching Qian with tool roughing and quenching Hou with wheel fine processing of method), to can in the Taiwan NC machine for quenching Qian quenching Hou of turning processing (to car generation mill), has is nice of statistics.
