At present the trend of a development of turning cutting tool is, continue to give out high speed and cutting tool of big feed cutting. The KB9640 of Kennametal company is a kind of surface besmears Fu has CVD aluminium alloy multilayer the whole of film type CBN lathe tool. According to saying, CVD aluminium alloy is multilayer film is had better fight crack tenacity and pair of good chemistry that diffuse and oxidize to wear away to resist integratedly with crescent moon depression tatty ability, the high reliability that adds tough CBN ground floor to suit to be used at bigger cutting deepness to fall more and efficient treatment. Its are consequently main utility is cast-iron to pearlite grey mouth material the thick, precision work that has high-power and hard steel, cold to temper by dipping in water hard cast-iron reach good film stuff to undertake rough machining. The big batch that this company still is aerospace, medical apparatus and instruments and food manufacturing industry to use data is machined, development gives cutting tool of a few kinds of new-style hard alloy. Among them KC5510 and KC5525 in order to have Na Mijing bead, can undertake high-power cutting and exterior besmear Fu have high-powered TiAlN coating to be main characteristic, can prolong cutting tool service life below tall cutting speed. Add bit implement design of microcosmic geometry configuration, can assure very tall cutting stability and admirable workpiece surface surface roughness. Cast-iron high speed treatment is to use what by company of Kyocera industry ceramics the cutting tool of CA4010 hard alloy of new development undertakes. The one big feature of this cutting tool is to have face of Fu of multilayer and compound besmear. Most the TiN coating that surface layer oxidizes to can resist; Film of deeper imperceptible grain Al2O3 is among, so that be below tall cutting speed, prevent combustion of cutting tool surface further; Ground floor is TiCN coating, it can resist the damaged of cutting tool and micro-crack arise. Cutting tool still designs form of geometry of the ZS that has anew chamfer that break bits, according to saying to be able to increase strength of the cutting stability of bit and cutting blade, reduce the vibration in treatment, apply to discontinuous reach burden cutting. Ceng Huo gets the Xcel cutting tool of patent to be produced by Sandvik company, its are main structural characteristic is to chose to use 80 ° razor blade to undertake machining. According to introducing it can provide high speed treatment, compare with photograph of lozenge razor blade, more apply to half rough machining to exceed heat-resisting alloy and titanium alloy. In be being machined according to saying, 80 ° razor blade can be the same as square razor blade same, use 45 ° cut horn to undertake machining, have process designing to be mixed easily consequently can reduce advantage of cutting tool tatty. This cutting tool still has the corner that can machine complex form spare parts place, admirable accessibility and the characteristic that can undertake machining in two direction are offerred in limited space. Compare with photograph of circular razor blade, have can decrease radial load and maintain the ply that cut bits changeless wait for a characteristic. In addition, sandvik company rolls out CoroTurnXS newly still especially small-sized lathe tool, use at the chamfer inside turning and small whorl (the whorl that is Φ 1mm like aperture diameter) . Should use on Swiss CNC machine tool, when bit outfit bores hole into boring lever, need to have cooling fluid supply, in order to improve a bits function and blade of effective cooling cutting. The diametical limits that boring lever supplies is Φ 10 ～ Φ 25. 4mm. Sometimes, not be treatment material however the size variation of spare parts itself makes cutting tool produces a problem in treatment. The TP3000 of new development of Seco – Carboloy company, use at having the spare parts turning that larger size changes namely. Can be opposite according to weighing it odd a small lot or the large part semifinished product of large quantities of quantities undertake discontinuous cutting and tall feed speed are machined. To treatment of tall productivity turning, by the HeliTurn system of Iscar company new development, its are main the feature is can clamp of edge tangent direction is gyroidal cutting blade razor blade. According to introducing, in cutting steel when, the cutting deepness that can achieve 8mm and bigger feed (about 1.
2mm/r) . Blade of 4 of bit gyroidal cutting assured the horn before radial, produce lesser cutting power thereby, increased the tall stability of cutting tool service life and cutting point. Systematic stock can be installed 25 or the clip of knife of cutting tool petiole of 32mm square. CNC Milling
