Challenge: If why undertake milling of efficient 2D profile modeling on titanium alloy. Solution: Use special cutting tool (for example milling cutter of COROMILL 690 long knife) . Expand ceaselessly as global middle class, also be in to the demand of the journey in low sky grow increasingly. Be in for example be called " golden brick Shikoku " Brazil, Russia, India and China, more and more people hope to get the business trip with low fare is mixed go vacationing service. Air-freight also is increasing. According to forecasting, 20 years aviation passenger traffic volume will increase future every year 5% , and air-freight quantity increases 6% . The challenge of the relation such as the flight demand that if where has managed to grow increasingly,front of global aerospace industry is facing and the environmental consciousness that elevate now ceaselessly. This asks we make a light aircraft, in order to reduce fuel cost and discharge capacity. Since period of time, titanium metal is compared with its outstanding intensity weight, make one of first selection material of aerospace industry. But the attribute that is fond dream of stylist of plane of this kind of achievement, make it became the nightmare that the metal machines. Nevertheless, roll out CoroMill 690 as Shanteweikekeleman, there was the special milling cutter length blade that can assume this heavy responsibility now. Aerospace industry still is met possibly to the favour of titanium metal deepen further. In Boeing 787 dreams (Dreamliner) wait for the most advanced aircraft to go up, the dosage of titanium has increased than old model twice, and in the future, 15% what titanium metal will hold plane weight. Ti-5553 is a kind of new alloy, its attribute is more outstanding even, be favorred in aerospace industry increasingly, replacing Ti6Al4V of vintage and puissant material. Ti-5553 has superior strength and very tall fracture toughness, suit to make particularly must bear the component of immense stress, for example structural component and landing gear. The specific challenge of the general challenge that titanium metal faces and Ti-5553 (it machines harder even) be: Each working procedure needs a basis a few already the general regulation of establish, undertake meticulous program and cutting tool choose, these regulation have: The demarcate cutting speed, tall feed rate that cooperates good treatment place to need, use cooling fluid, rate discharging bits that keeps good, use sharp cutting tool and appearing tatty gives when omen at first change, and cutting tool and workpiece are contacted in shift avoid to interrupt feed in the process. Be based on afore-mentioned considerations, shanteweikekeleman designs CoroMill 690 of a kind of new-style milling cutter, use technically at the milling of efficient profile modeling of titanium spare parts. One of main characteristics of CoroMill 690 are position of new cone razor blade, this makes it can resist axial cutting force, and axial cutting force is the soft costal region that at present the other on the market grows blade notion. Its were to reduce bit shift as a result, improved the security of craft thereby, raised feed, prolonged cutter hub life, because it prevented a bottom to discharge breakdown,this is. The new-style design of blade of this kind of 4 cutting brought Gao Sheng to produce efficiency and economic benefits to working procedure. Another characteristic of CoroMill 690 is the chamfer holding bit that its course optimizes. This one characteristic is helpful for discharging bits smoothly, decrease cut bits to jam, improved the security of craft thereby, raised cutting parameter. As a result of the hear resistance of titanium, refrigeration is crucial in machining a process, cooling purpose is to make edge and cutting tool surface won't overheat. CoroMill 690 uses the cooling fluid that carry a department, such, should undertake square shoulder mill and face mill hollowness, model when antrum or complete chamfer, can achieve first-rate to discharge bits effect. When cutting titanium metal, it is very easy to cut bits clingy edge, cause milling cutter below one round to rotate again cutting cuts bits, often can cause blade of blade line collapse. Razor blade of CoroMill 690 of avery kind of antrum has respective cooling fluid opening / note fluid, with will solve this problem, and the edge function with constant aggrandizement. Another clever solution is whorl cooling aperture. Long knife milling cutter has a lot of bit. Bring to bear on to every aperture cooling fluid needs to have very high pump capacity and pressure. And CoroMill 690 is different, it is OK according to need, stem the aperture that does not have need, thereby utmost land increases current to the opening that has need. Anyhow, introduce milling cutter of new-style CoroMill 690 to will bring a lot of profit to aerospace industry manufacturer, all these element assembles rise, can promote craft security, make cutting tool has the life that grow and can cast more. What cooperate to machine a requirement to titanium alloy again is masterly understand, cutting tool solution will be this kind of appropriative to increase the use of titanium metal to provide support ceaselessly, especially Ti-5553 the important material of industry of this kind of aerospace. Conclusion: Be defeated to increase ceaselessly as aviation carry, to low aviation the demand with freight also is in passenger transport to promote increasingly, predict this kind of trend will continue. Meanwhile, environmental protection consciousness also is being strengthened increasingly, put forward to reduce the firm demand that contamination discharges to the company thereby. Conduce to the titanium metal that reduces plane weight using already increased significantly. New titanium alloy Ti-5553 is had more positive attribute, but treatment difficulty is taller also. Shanteweikekeleman already developed a CoroMill 690 of milling cutter of a kind of appropriative titanium, solve a lot of inherent problems of titanium treatment thereby. Case analysis: the structural part that the economic effect that machines Ti-5553 makes to using Ti-5553, executing milling of 2D profile modeling is difficulty place. This treatment working procedure uses CoroMill 690. This is one kind deploys interface of coke full Capto (model 8) long knife milling cutter, milling cutter diameter is 84 millimeter, long for 63 millimeter. The cutting condition of working procedure is: Cutting speed is minutely 22 meters, every tine 0. 13 millimeter, radial cutting deepness is 6 ～ 18 millimeter, axial cutting deepness is 20 ～ 40 millimeter. Brand of place choosing razor blade is GC1030. Employ this one solution, manufacturer can increase the manufacturing time of every razor blade 50% .
