Summary: Enter 21 centuries, our country manufacturing industry forward high speed, efficient with tall accurate treatment way develops. Wait for the development of the industry as domestic car, aviation and mould. Equipment of efficient CNC Machining gets popular. Stuff of difficult treatment of all sorts of tall hardness, tall tenacity is right the exterior coating technology of labour, mould raised taller requirement. One, introductive 19 centuries 70 time, the simple coating device that is used at research begins to appear. To 20 centuries the coating equipment of 70 time commercialization is supplied at the world. Technology of 80 time coating enters 20 centuries industrialized big production. At the beginning of 21 centuries, coating technology makes the new technology that common people fixes eyes upon. Coating technology is to answer the technology of a kind of finishing that market demand development rises. Because this technology can make surface of labour, mould acquires admirable integrated and mechanical property, raise machining efficiency to reach substantially thereby prolong service life of labour, mould, accordingly it already became contented and contemporary machining one of crucial technologies that efficient, high accuracy, high reliability asks; And its apply a domain to expanding quickly. Coating development is facing unprecedented opportunity... . 2, the application of coating technology 20 centuries 80 time, domestic industry group has realized the value that coating uses in cutting tool respect. . Works of much home tool introduced coating device from the United States and Switzerland. Of this paragraph of period introduce a technology to remove huge to invigorate to the coating technology development of our country with stimulative action. The coat that has a side with Yu Dao at that time returns TiN of much be confined to, breed is onefold, without specific aim. But fall in this kind of state, we still saw a variety of advantages of coating: 1. Nitrogen changes titanium (the TiN) coating application in respect of gear cutting tool hob of coating of durability of 1800 ～ 2100HV raises velar layer hardness 2 ～ rate of 10 times cutting rises hard data of 90 ～ 150m/min cutting from 30 ～ 40m/min general high-speed steel rises to be fought to 300 ～ 400HBS by <220HBS " stick a knife, phenomenon sticking a knife reduces cutting efficiency efficient the flying development as processing technique and appear of all sorts of material ceaselessly. At the beginning of 21 centuries, domestic tool industry to raise level of cutting tool product, in order to get used to the manufacturing industry need that high speed admits, introduced much stage again current relatively advanced compound and multivariate coating equipment. Meanwhile, the coating company that has strategic eye domestic and internationally relatively and coating equipment manufacturer also enlarge scope of business to our country mainland. In the applied respect of coating, had cast off the concept that cutting tool is confined to on traditional sense. Its apply limits to enlarge component of aviation of accurate punch mould, spaceflight, average machine spare parts and electronic fittings plug-in unit. In the meantime, coating technology is controlled those who wait for development of many sided science and technology to drive by vacuum, electron, automation, roll out ceaselessly on foundation of original coating breed more high-powered replace coating, and have new high-powered coat come out ceaselessly. Wait for coating of rice of efficient and compound accept like TiAlCN, AlCrN, TiSiN, Si3N4+AlCrN appear, improved the service life of labour, mould and treatment efficiency greatly, got applied extensively, get great attention. Same we compare coating to be in again the applied state of respect of gear cutting tool, see a picture 1 reach the graph is shown 2 times. Graph the cutting contrast of coating of 1 common TiN and special TiN coating pursues the cutting contrast on gear hobbing cutting tool carries all sorts of 2 new-style coat the simple contrast of 2 groups of data, we can see the high speed of coating technology develops, to manufacturing industry development provided a kind of concise and efficient technology measure, use this kind of method, can reduce production cost substantially not only, and can greatly managing the sources of energy, reduce environmental protection the devoted, long-term goal that is helpful for implementation can developing continuously. 2. To a certain number of planting coating is in under the coating technology application in respect of other cutting tool the function difference below environment of different cutting tool, different treatment is reflected, see a picture 3 ～ graph is shown 5 times. Graph 3 auger cut treatment to pursue 4 milling machine a graph 6 phone mould pursues 5 thread machining 3. Coating technology reachs the coating of applied Injection Mold Tooling of respect of mechanical spare parts to carry coat in the mould, can make mould more wear-resisting caustic, and raise the sex of drawing of patterns of the mould, achieve thereby prolong mould service life, raise the goal of product quality. If door subsidiary is in on the west its phone mould (see the graph is shown 6 times) on after use coating, mould by write modular life every time before 20 ～ 300 thousand, lengthen 100 ～ 1.15 million. Because decreased to write modular number, the material of every product infuse also drops somewhat, cost respect gets controlling. Because use coating hind, the glossiness of product surface also gets rising, leather grain face is more exquisite, exterior quality rises, enhanced the competition ability of the product, created considerable benefit thereby. The problem of service life of mould of punch of punch mould coating and stamping workpiece quality is in all the time troubling processing factory trader. The occurrence of coating and the success that its get on in mould of high spirit punch apply, make a few technology personnel that are engaged in cold punch treatment for a long time generated strong interest. Use coating pattern in expensive precision work not only nowadays, connect big also in common screw treatment batch to use coating pattern (see the graph shows) 7 times. After use coating mould, odd a mould by previously only 4h machines life, raise 8h above; And reduce school model time greatly, reduced workload, improved manufacturing efficiency, the bolt surface surface roughness that hits also than have before very big change. The development of coating of mechanical spare parts as aviation, mechanical industry, raised taller requirement to transmission and assembly parts. The typical coating technology that two kinds introduce to apply at mechanical spare parts here: 2 vulcanization molybdenum (MoS2) , DLC(sees a picture 8 reach the graph is shown 9 times. This kind of coating applies at load big, chafe or wear away the systematic part that bigger need lubricates partly. Pass coating processing, can make spare parts life is lengthened 10 times the left and right sides, and appear not easily bite dead phenomenon. Graph mould of 7 standard component -- the application of the coating of applied graph 9 MoS2 that crossed essence develops coating of graph 8 DLC 3, the last word moves toward all-pervading trend to fall gradually in coating technology, will continue to transfer to technology of coating of class of high-powered accept rice. As the development of material science, new-style material change quickly comes out ceaselessly, also offer new task ceaselessly to machining a tool, machine the need of means to satisfy cutting etc, the development of coating technology also is sure follow closely develops tide, get rid of the stale and bring forth the fresh. If be in the diamond coating cutting tool that extends phase and CBN coating cutting tool at present, answer namely alloy of tall silicon aluminium alloy, titanium the new coat breed of with etc weak data research and development. The applied domain of coating technology also will expand increasingly, be sure to indicate more significant position in manufacturing industry. CNC Milling CNC Machining
