Cutting machines the main base craft that serves as production technology, as the development of production technology, also obtained very great progress in 20 centuries end, entered in order to expand the cutting technology with high speed cutting, new development and treatment method, development that offers whole set technology to be a feature new level. It is manufacturing industry in essential industry department, mix like industry of auto industry, aerospace, energy industry, military affairs industry the processing technique with the main branch such as burgeoning mould industry, electron industry, also be the main factor that these industrial departments develop quickly. Accordingly, the country such as the beauty that develops in manufacturing industry, heart, day is maintaining the momentum of rapid development. Metallic cutting cutting tool regards numerical control machine tool as tooling of indispensable form a complete set, in CNC Machining technology drive, entered " numerical control cutting tool " development phase, show " 3 tall one only " (namely efficient, high accuracy, high reliability and special change) characteristic. Clearly, it is at the beginning of 21 centuries, although technology of close clean figuration, accumulation figuration technology is the new technology that has an outlook very much, but the position that cutting treatment regards production technology as main base craft won't be changed. Can see in the tendency that develops from current manufacturing industry, manufacturing industry development and human society progress machine the double challenge that pose to cutting, this also is the main trend that processing technique of the cutting at the beginning of 21 centuries develops. The new cutting technology such as the dry cutting that high speed cutting will become new technology to be a delegate with high speed cutting currently, hard cutting has shown a lot of advantages and powerful vitality, become production technology to raise the treatment efficiency and quality, main avenue that reduces cost. Accordingly, developing the new cutting technology such as high speed cutting to promote the development of production technology is the new job that contemporary cutting technology faces. Contemporary high speed cutting is not cutting speed a few raising, it is to need to be on the foundation that production technology progresses in the round and innovates further, the significant progress that incorporates the technology such as structure of material of numerical control machine tool, cutting tool, coating, cutting tool, the twice of the cutting rate that ability achieves and feed speed rises, ability makes cutting of manufacturing industry whole machines efficiency to have rise significantly. level of current high speed cutting practical change, make our country machine machines integral cutting efficiency to raise 1 ~ 2 times, contractible the difference with industrial developed country, it is the professional that our country pursues cutting treatment and cutting tool technology the major challenge that in the effort of new century target knead dough faces. Hard cutting is an application domain of technology of high speed cutting, machine hard part of temper by dipping in water with Chan Ren or multiple-cutting-edge tool namely, it is more businesslike than conventional grinding treatment tall, flexible good, craft simple, investment is little wait for an advantage, already produced better result in domain of a few application. In car line of business, machine 20CrMo5 oil hard gear with CBN cutting tool (the aperture inside 60HRC) , replace grinding, exterior surface roughness can be amounted to 0.

22 μ M, already made the new technology that industry of domestic and international automobile popularizes. Since innovation processing technique is long-term, if difficult treatment material is austenite stainless steel, tall hard steel of manganese steel, temper by dipping in water, composite material, wear-resisting is cast-iron etc is cutting all the time the difficult problem in treatment, cutting efficiency is low, cutting tool life is brief. As the development of manufacturing industry, in 21 centuries the dosage of these material mushroom, the contradiction of treatment will be more outstanding. Meanwhile, the material of the product is formed will optimize ceaselessly, new project material also comes out ceaselessly, and new profile of avery kind of expects use raised new requirement to cutting treatment. If the auto industry that centers quite is machined in cutting, its engine, drive implement the scale of the silicon aluminium alloy in the spare parts is increasing continuously, begin to introduce magnesium alloy and new high strength cast-iron, in order to reduce the weight of the car and economic specific power consumption. Be like again in aerospace industry, titanium alloy, nickel radical alloy and the applied scale that exceed the difficult treatment material such as heat-resisting alloy, pottery and porcelain and treatment difficulty also will increase further. Whether efficient treatment these material, the develops speed and manufacturing industry whole standard that matters to the essential industry department such as our country car, aerospace, the sources of energy directly, it is the biggest challenge of pair of cutting technologies. We must begin exploration from now, with from go up at all solve difficult treatment material to use the century sex difficult problem that reachs diversification of its breed function to bring in great quantities, innovation processing technique, development includes laser inside new " edge " with treatment method. After the demand of contented manufacturing industry enters 21 centuries, the trend of product diversification and individuation is farther aggravate, the product of manufacturing industry updates speed to be able to be accelerated greatly. The development of new product of avery kind of means the major change of spare parts function, structure, material, also be the development job that offers to cutting treatment, resemble everybody be like screw pump heply, etc fast industry of the spline of centering of diameter of gimbal, bottom, electron pressworks the product such as circuit board, all without exception is reflecting the gain of cutting technology and cutting tool. Will accelerate as what the product replaces rate henceforth, form didymous cutting processes new challenge. Not only such, what use cutting treatment currently is flexible the positive result that reachs contemporary cutting treatment and cutting tool technology, innovatory spare parts machines a method, show investment little, yield big, get effective fast characteristic. No less than is in on the car engine that 90 time build the century, drive implement the place on product line reveals centrally in that way: The new treatment technology such as the technology of barrel type broaching that the integral hard alloy that cylinder body aperture fastens gets gear of the craft of milling of diamond high speed that cuts lid of craft, crock, synchronized, the manufacturing pitch time that makes build product line shortens, product quality rises, investment decreases in great quantities, show the tremendous potential that cutting machines adequately. Below this kind of setting, manufacturing industry machines the demand of new technology, new product to will reach all-time height now to cutting, this since challenge to cutting technology, also be the challenge of outmoded to industry of our country cutting system.
