Although Japanese made coating cutting tool enters an international market later, but because throw an advanced technique ceaselessly, make its already entered the place with banner technology in domain of world coating cutting tool. Manufactory of Japanese each tool cutting tool of devoted coating manufactures new technology of day and night research and development in. The article is developed with company of data of 3 water chestnut and apply the new technology in the product to be exemple, introduce the development state of affairs of technology of coating cutting tool. 1. The technology that sees coating cutting tool from market demand develops prospect from raise the product precision and quality, angle that reduces environmental pollution to set out, the manufacturing technology that the mechanical manufacturing industry inside Japan developed an on a grand and spectacular scale in manufacturing site and processing technique are innovated. But in the innovatory process in processing technique, the certain property of coating cutting tool did not achieve the requirement of the user completely in fact, the phenomenon of the felt that cut bits that affects cutting tool life is among them one of. That is to say, although coating cutting tool is mixed in wear-resisting function,be able to bear or endure the leap was obtained to develop on collapse blade function, but how overcoming phenomenon of the felt that cut bits to be returned in order to increase function respect not quite advanced. The harm that phenomenon of this kind of felt that cut bits causes is in the treatment of the difficult cutting material that is a delegate with stainless steel, nodular cast iron happen from time to tome. Because it is belonged to,be not wear away normally, and expect hard, the metabolic range of cutting tool life is so bigger. Because be put in this kind not to stabilize an element, when be being machined normally must can machine workpiece to count index set inferior, this is reduced in what finished cost affected on certain level. Accordingly, through improving the appearance of blade of cutting tool cutting smooth sex, prevent cutting tool and by phenomenon of felt of cutting material generation, the cutting bit that acquires processability to be able to be improved thereby appears particularly important. Although these surfaces are slick,the technology is the property of wear-resisting bad news that develops coating material itself with utmost ground, raise treatment stability to be a purpose thereby, but the strategy that each companies use and method have each however different, have a plenty of use mechanical method, some is through improving coating the organization obtains the cutting blade with slick surface. 2. The product with smooth technology applicable place is in the surface inside the treatment speed limits with CVD coating commonly used razor blade, because cutting blade wants to bear the high temperature of 500 ℃ above, because this is most,besmear on base material Fu the A12O3 film with can fine thermal stability. A12O3 coating belongs to crystallization sex pottery and porcelain, if besmear to raise wearability too thickly, of plated film surface concave and convex degree also can increase subsequently, exterior surface roughness is increased. In cutting process, by cutting material easy felt is in cutting tool surface, and machine wallop effectively dispersedly hard when interrupted cutting, the happening that causes the unusual loss such as blade of the tumour that accumulate bits, collapse easily thereby the research and development that early of company of data of 3 water chestnut begins to undertake smooth technology will improve performance of cutting tool cutting using face of coating cutting tool works, carried out achievement of multinomial research and development. Regard the first face that uses at the product as smooth technology, using on the bit brand US7020 of stainless steel of high speed turning, the appearance that handles via machinery was being carried out after CVD coating is smooth technology. In Fu of the besmear on base material of coriaceous hard alloy with columnar what brilliant TiCN film and atomic and smooth A12O3 film give priority to body is multilayer after horniness film, this coating cutting tool shows good cutting performance in the cutting treatment of stainless steel, plus the face that used the place before be like to narrate smooth technology, controlled the felt appearance of blade of the cutting that be opposite by cutting material effectively. To stainless steel treatment, although be in,the condition of the high speed cutting of 200m/min issues V ＝ , also can assure stable cutting tool life. Additional, also can use the face on the UE6010 of brand of representative razor blade that is used at turning rolled steel and UE6020 smooth technology. Smooth technology calls the surface that applies to afore-mentioned material to pledge " smooth coating technology " , it is to use special CVD technology, will obtain slick coating surface through controlling coating to grow. It is means of processing of machinery of a kind of blame, the smooth sex of coating surface can come true below the circumstance that does not injure coating. 3. First-rate " completely black super and smooth coating " the technology is machined in turning cast-iron on UC5105 of used brand of newest razor blade and UC5115, applied distinctive chemistry to handle the appearance smooth technology and mechanical and smooth technology the compound finishing technology of organic union -- " completely black super and smooth coating " . Of this technology apply can make the smooth sex of coating surface achieves perfection. Besides the surface beyond smooth technology, technology of another kind of brand-new coating material tall wear-resisting also applies to afore-mentioned brands. To cutting cutting tool, nodular cast iron belongs to one of material of particularly difficult cutting. But because used name of UC5105, UC5115, make the unusual damage of cutting tool decreases substantially, solved nodular cast iron to machine difficult problem. Additional, it is the application of the UC5105 brand of base material with tall hardness hard alloy, make traditional coating cutting tool is finished hard, the treatment of cast-iron high speed that belongs to domain of cutting of cutting tool of pottery and porcelain becomes a possibility.
