Year of sales revenue of aerospace domain about 20 billion euro, can provide 80000 works station, it is one of fundamental application domains of German machine tool industry, its also exceeded German this locality far to the demand of machine tool tool the level of domain of machinery of other motive force. And the character demand of the raw material that uses in this domain and component also is a when create a company to the machine tool major test. Germany somewhere a Boeing 747 planes are taking off. Quicken this colossus that hefts 400t to 250km/h in the time that is less than 40s, this is test of the raw material that uses to plane place. This kinds of plane raised a lot of requirements to the manufacturing business of aviation manufacturing industry, have confrontation among them the requirement of current economy crisis. Relevant investigation and study thinks: The passenger number that travels by plane at present and airfreight estimate year of increase rate extraordinary stability, carrying trade of the traffic in the air that the income in German aerospace company takes 60 ％ its average increase rate of 20 years will be stabilized henceforth in 5 ％ . In for military use and spaceflight domain, also having stable yield, can have the growth of certain level even. According to be opposite the integration analysis of aircraft increase rate and average service life can reach: Henceforth the demand of new aircraft inside 20 years is in 20000 above. Financial crisis did not affect current financial crisis to do not have the aerospace industry to Germany to cause bigger effect to the growth of aircraft manufacturing industry. The German aerospace Joint Industry Conference that produces business profit on behalf of German aerospace industry (BDLI) spokesman Mr Christopher Bach says: "Our working load is quite at present saturated. " in light of the angle from long-term development, chairman Dr. Thomas Enders of BDLI thinks, current financial crisis won't rent business and each line that have financial difficulty at present to cause major effect to aviation. Make in aero production in, aerospace technology put forward to making the cutting when machine a series of the technology asks (graph 1) . On one hand, the characteristic that aero component is having very complex, take time to be made with not easy treatment painfully; On the other hand, the raw material that uses in aerospace domain and machine tool make the raw material in the domain there is very big distinction on function, 3 kinds of data that use in aerospace domain brought very great difficulty to metallic cutting treatment. Graph 1 aerospace domain is one of main fields that German machine tool creates, the metallic data that uses in this domain machined craft to raise very tall requirement to metallic cutting is nickel radical alloy above all, the most typical product that uses this kind of data is leaf of turbine lamina, propeller fan and aircraft power system the housing component of hot area of the broil around; It is titanium next, titanium is a plane the main material in the travelling mechanism when the ground glides and component of other hydraulic pressure; Still include CFK additionally, the plastic material that this kind of carbon fiber enhances uses at structural member together with metallic titanium normally make, the perpendicular empennage that is like a plane, strut bar and decelerate board. The key of 3 kinds of afore-mentioned material is in effectively cutting to be provided at the knife. Accordingly, be in to cutting tool product the hot phenomenon in aerospace market is no wonder. Aerospace product manager Mr Oliver Baum of Ceratizit company expresses: "Aerospace domain is Ceratizit company divides the market with the rapiddest growth outside energy field. " the need that the cutting tool that to make they manufacture can fit aerospace market, ceratizit company threw charge of many research and development. "The development trend that titanium alloy machines is very clear, the manufacturing business need of titanium alloy spare parts can raise his to machine solution of socioeconomic cutting tool apparently. " Mr Baum say. Manufacturer of equipment of Nextpage machine tool machines the competition of efficiency respect to be in machine tool manufacturing industry in the metal, the degree that the competition of function of the biggest cutting had entered cutting tool to turn white-hot. "Metallic cutting machine tool is facing power bigger, rotate speed is faster, more economy and use quicker way to develop. " the say of general manager Mr Andreas Podiebrad of company of technology of Handtmann A-Punkt automation. In aerospace domain of Germany, handtmann company is provider of equipment of a famous machine tool, their sales revenue in this domain occupies the 80 ％ of company gross earnings about. Mr Podiebrad says proudly: "The spare parts that useful Handtmann machine tool machines in an any modern planes. " and be located in the DST company near Munich in this domain also have international competition ability extremely -- its the sales revenue in aerospace domain takes a company about the 1/3 of total sales revenue. The vertical lathe that is used at cutting to machine spare parts of engine of spacecraft worm wheel and the milling machine that can machine the plane landing gear with long 5m are them advocate make a product. Current, crossing the combination of the enterprise to develop a project basically is rigid stronger, decrease brace up performance is better with cutting force bigger treatment machine tool, in the product competition ability with assure to while high accuracy and Gao Ke rely on a gender, be had better. Manager of product of Okuma company aerospace Mr Max Pieper says: "Current, the machine tool that processes high strenth data times welcome. " the machine tool business of Japan and other country also increased the strength that enters aerospace market. Mr Pieper says: "Aerospace market is having very big allure. " at present, okuma company occupies the 10 ％ of gross income about in the sales revenue in this market. Japanese enterprise wins another successful case in aerospace domain is company of Mori Seiki of business of machine tool production. "Come for years, we are the partners of supplier of the system in aerospace market all the time. " say of general manager of department of power plant of Europe of Mori Seiki company Mr Ralf Riedemann, this company occupies the 15 ％ of gross income in the sales revenue in aerospace domain. What the is manufacturing industry of complex package aircraft to grow ceaselessly more demand that supplier business provides brings about productivity of the business in this domain is ceaseless rise, also rose at the same time large company is complex to can be being offerred inside course of study the demand of the high quality supplier of module product or system, package and component include the drive from plane travelling mechanism electric component arrives part of complex cab form a complete set. "To great majority medium or small supplier, these modular component ask they must improve their productivity. Accordingly, in aerospace domain, of processing technique compositive more and more general also " . Mr Ralf Riedemann of Mori Seiki company thinks so. Be in through different processing technique the combination in a machine tool, the enterprise can shorten apparently the manufacturing handling time of component, reduce manufacturing cost thereby. In the meantime, compositive in facilities of a treatment 2 class engineering technology, if compositive balance is mixed,detect the heat that the technology had become people to pay close attention to. General manager Mr Andreas Podiebrad of Handtmann company (graph 2) point out: "Current, automation is the problem of a key that people cares, this also is another gain that brings aerospace product manufacturing company. " general manager Mr Andreas Podiebrad of company of technology of automation of graph 2 Handtmann A-Punkt believes firmly: "Current, automation technology is a when people cares serious problem. " the result that the development direction that the cutting in aerospace domain machines had had a special clarity, its develop a program to had been made 2020, the target is discharge with what compared CO2 2000 decrease 50% , of azotic oxide discharge reduce 80 ％ , noise reduces 50 ％ . Accordingly, the enterprise threw the 15%~20% of sales revenue to be used at research and development, make a plane smaller, so that reduce oily cost. The phenomenal backside under cover that is helpful for environmental protection in this kind weighs wanted capital issue. According to expert estimation, the weight that every reduce 1kg can be in spaceflight equipment manufacturing industry managing 5000 euro. Prospective plane will use the CFK material that metallic titanium enhances and other and plastic material to make entirely, and nickel radical alloy remains the main product in aircraft engine, metallic titanium has important place in the travelling mechanism of the plane.
