When the technology division of good user, make machine tool product can the requirement that utmost ground satisfies an user, the applicability that raises a machine tool ceaselessly and dependability and its use benefit and efficiency, create more value for the user, it is the ultimate goal of machine tool production enterprise and core competition ability. Accordingly, focusing user demand, research and development has a technology to make the important intention that transition of machine tool industry upgrades only. The object of 3 great main services that aviation manufacturing industry, automobile manufacturing industry and mould manufacturing industry are machine tool manufacturer, the requirement that they raise increasingly to precision of spare parts treatment and efficiency promotes the development of machine tool technology ceaselessly, it is the motivation that machine tool product innovates. For example, flexible closely related the demand of department of the occurrence all without exception that turns machine tool of numerical control of machining center of high accuracy of transfer matic, high speed, compound treatment and much axis linkage and this 3 industry. The 1 focusing of successful secret Ji of Ecospeed user demand is contemporary great majority of plane structural member is laminose kind of spare parts, its characteristic is structural appearance complex, dimension big, wall is large groove of small, sunken acupuncture point is much, and requirement quality light, intensity quality of tall, surface is good. It is normally be machined by semifinished product of whole aluminium alloy and become, the bulk that its metal excises is as high as 80%~95% , because this asks the cutting rate of the machine tool is high, main shaft power is great, rate of excision of unit time stuff is old. A typical plane structural member is shown 1 times like the graph. Graph the company of DS-Technologie of Germany of plane structural member of 1 model (DST) it is manufacturer of famous heavy-duty machine tool, its dominant product is type of large dragon door machining center, set aviation to create a department, the treatment technology research that pursues plane structural member technically and aviation make the research and development of new machine tool. The research of DST makes clear as a result, from 20 centuries the much axis milling machine of 70 time arrives machining center of 5 axes linkage cannot satisfy the dragon door type of 90 time completely the requirement that modern plane structural member machines. Accordingly, the new-style machine tool that decides structural member of plane of research and development is machined -- Ecospeed. Above all, need makes clear the problem that Hunan user exists, pass summary tens of year the experience that plane structural member machines, raise the target of machine tool function that user place expects, see a table 1. Used dragon door formula in the past 2 rotor that 3 mobile axes that the basic conception of machining center of 5 axes linkage is milling machine of dragon door type add milling head, make machine tool of 5 axes linkage thereby, milling head becomes a key. Undertook an analysis to a variety of type that place part and circumgyrate type milling head, the function when be being used at machining plane structural member to its undertakes evaluating, the result sees a table 2. Function evaluates minute of 5 level, + + for very appropriate, + it is better to be, + - to can be used, - for poorer, - - for improper. Visible, no matter place horny pattern or circumgyrate type milling head,exist the part that makes a person not quite satisfactory. 2 have a technology only: Head of Sprint Z3 main shaft for from go up at all the weakness that overcomes the type that place part and circumgyrate type milling head, head of new-style Sprint Z3 main shaft uses 3 rod and through traffic moves an orgnaization, its internal composition is shown 2 times like the graph. Nextpage is seen from inside the graph, orgnaization of motion of 3 lever paralell connection is adopt drive of ball guide screw respectively by 3 servo electromotor, the composition of 3 mobile unit that distributings by 120 ° . Below drive of ball guide screw, slide is respective the linear slideway on edge base is mobile, the shift of slide urges the staff that can swing, platform of campaign of drive of repass universal hinge, make the main shaft on athletic platform makes the deflexion of Z axial shift and A axis and B axis direction. Carry out a proof, orgnaization of motion of paralell connection of this kind of 3 lever can satisfy treatment of plane structural member completely to expect the demand of function index. What should point out is, although the athletic principle of head of Sprint Z3 main shaft is novel, but all component, including main shaft of servo electromotor, report, linear slideway, bearing and versatile hinge is the component of standardization, by professional manufacturer production, had won wide application in numerical control machine tool, make 3 lever paralell connection carries the dependability of head of motive compose main shaft can be obtained thereby assure adequately. If the graph is shown 3 times,install head of the Sprint Z3 on pillar main shaft. Graph 3 installation the head of Sprint Z3 main shaft on pillar is seen from inside the graph, main shaft head falls to rise along slideway of two sidetrack sex in the drive of ball guide screw of two side by configuration fall. The end that uses double guide screw is the centre of gravity that makes driving force is in main shaft component, improve its trends performance. Main shaft slide carriage and pillar are solder by armor plate and become, close, light quantified structural member, in order to reduce the inertial effect when shift. On the foundation of head of Sprint Z3 main shaft, form Ecospeed of center of high-powered CNC Machining, its are overall configuration sees a picture 4. See from inside the graph, the characteristic that the machine tool configures is all motion are finished by cutting tool a side, the work on vertical workbench splint is being secured in machining a process is not mobile. What perpendicular treatment can make high speed is excised is many cut bits to be able to discharge quickly. After workpiece treatment ends, splint moves to be mixed to the exchange of machine tool a side assemble and unassemble labour, retroflexion next 90 ° , make workpiece can assemble and unassemble in horizontal position. Milling machine of a variety of dragon door type that center of high-powered CNC Machining of graph 4 Ecospeed and past use 30 years and machining center are compared, ecospeed shortened part handling time about 6 times, the metal excision rate rose nearly 7 times, if pursue,5 are shown. The success application of Ecospeed of center of high-powered CNC Machining makes DST company machines a domain to be in world banner standing in plane structural member in recent years. The company of Zimmermann of Germany of planer-type milling machine of 1 FZ33 of new generation planer-type milling machine of Zimmermann company to its FZ planer-type milling machine of range of products undertook continual improvement is mixed rise, in order to satisfy the new requirement of auto industry and aviation industry. The most typical case is new generation is tall a FZ33 of movable type planer-type milling machine. Special design uses this model at to aluminium have 5 complete treatment with composite material, and to steel the efficient precision work that has 5 axes linkage. The drive technology through using research and development and the system of gear rack drive that use newest generation, provide high-powered linear guide, try to move component quality quantifies a design to make feed speed and acceleration rise apparently. The fiber that passes use high-tech enhances sexual stuff stuff, raised airframe to bear the weight of significantly the tigidity of the component. Space of machine tool work is with machining large airlines structural member is mixed the car is truckload model, plan Cheng is X axis 40m, y coaxial journey is 6m, z axis journey is 3m. Suit with this photograph, so that make full use of,this company used VH2 of new generation milling head other side improves the machine tool brings advantage, the cutting parameter that rises considerably makes FZ33 right aluminous cutting of big bit amount becomes a possibility. The VH2 milling head of new generation had high speed basically to machine all performance that light alloy place requires: The aggrandizement of ground of clamp system utmost of runner shaft coming back rough machining function, the drive of worm of high rigid worm gear that takes water-cooling and distinctive main shaft grease complement automatically lubricant system ensured the long-term stable reliability of equipment is mixed low safeguard a gender. Initiate of 2 whole worlds: M3 ABC milling head the difficult problem that to solve similar plane structural member groove of sunken acupuncture point machines, this company research and development a kind of milling head M3 ABC that has 3 rotor, if pursue,6 are shown. Nextpage is seen from inside the graph, the distinction of M3 ABC milling head and milling head of traditional corner type depended on increasing but along special design, the B axis of the arc slideway deflexion of high accuracy and tall stiffness is rotational, spend from 2 freedom turn into 3 freedom are spent. The circumgyrate angle of axis of C of M3 ABC milling head is ± 360 ° , a axis can make main shaft swings 110 ° of ± , and join between A axis and C axis but the B axis of 15 ° of deflexion ± , the structure is very compact. 3 freedom of M3 ABC milling head are spent and enough big deflexion range makes the treatment of 6 axes linkage that the milling machine of type of ZF100 dragon door that uses this milling head can realize Gao Rou sex, and can make sure cutting tool is in first-rate space attitude and use optimized feed speed to undertake machining, shorten substantially thereby handling time, acquire first-rate exterior quality at the same time. This one innovation from go up at all the concept that changed treatment of material of aluminium alloy, synthesis and treatment of model material whole and steel and high speed of cast-iron spare parts, overcame long-term since milling head of type of A-C axis corner machines medium certain limitation in 5 axes linkage. The groove of typical plane structural member often has the inside face of rake of ° of 3 ° ~5, the corner type milling head that uses A axis and C rod machines special inconvenience, need to adjust the attitude of milling head repeatedly in corner office especially. Have the aid of has the M3ABC milling head of ABC axis to machine this kind of groove is very ideal however, if pursue,7 are shown. The main drawback of the milling head of conventional the type that place part that has A axis and C axis is to be in when A axis is in 0, appear " dead center " , the C axis of milling head is right now invalid, it is when milling head namely when perpendicular position, main shaft cannot be in deflexion of C axis direction. Although very small gesture changes main shaft, also need C axis to make great circumgyrate gift come true quite, reduce treatment efficiency and quality of spare parts surface apparently. New-style M3 ABC milling head criterion otherwise, although be in the corner office that machines groove of spare parts sunken acupuncture point, also can maintain constant tall feed, reduce cutting tool significantly thereby wear away. Because have 3 rotor, need the smallest roll to be able to realize main shaft to change in the attitude of any any direction, angle only. In addition, c axis recalls at high speed after needing to circulate in each treatment no longer, can simplify numerical control program and managing and many main shaft attitude adjust time. On foundation of M3 ABC milling head, the FZ100 that Zimmermann company rolled out 6 axes linkage uses milling machine of diplodocus door type, its exterior is shown 8 times like the graph. Graph 8 FZ100 moves milling machine of diplodocus door type to be seen from inside the graph, crossbeam but along the machine tool the stationary mast of two side is in X axis direction is mobile, beam of edge of main shaft slide carriage moves in Y axis direction, and main shaft ram rises in slide carriage fall (Z axis) . Slide carriage of crossbeam, main shaft and main shaft ram are used light quantify design principle, the structure is optimized through relapsing, make the quality of component of machine tool shift lighter not only, and basic when the job constant, make the negative effect of force the least, assured the high dynamic performance of the machine tool thereby. Machine tool two lateral pillar is integral structure, the biggest length is 8m. Suck to make sure tall tigidity of the structure is mixed brace up quality, pillar solders by the armor plate through heat treatment and become, among them fill has special fiber to strengthen mixture (DemTec) , the working stability that can keep long-term and need not safeguard. This kind of unique pillar design has high fever stability and flutter and oscillatory tall damp, can assure the expensive measure precision that the spare parts machines and fast face quality, the outline precision far from of the dynamic function that its machine a process and workpiece is general and cast-iron and solder steel structure can is likened to. The drive of orgnaization of rack of unoccupied place gear of very close to each other that crossbeam establishs capital department by two side. This one layout makes actuating device is far from treatment area, and be adopted easily defend perfectly, be helpful for assuring working precision for a long time. The oldest floating rate of crossbeam can amount to 60m/min, the biggest acceleration is 4m/s2. Workbench is whole cast-iron, length is 3800~8800mm, width is 3000~4000mm, ply is 220mm, direct installation is on foundation, in order to make sure its are rigid. Of workbench the biggest bearing ability is 20000kg/m2. The main shaft power of M3 ABC milling head is 60kW, the biggest rotate speed is 22000r/min. Trend and look into as user demand increasingly diversification and high-powered change, the machine tool of general numerical control that batch manufactures encountered grim challenge. Prospective development has two kinds of tendencies: One kind is with some kind machine tool of general numerical control is base model the variety that adds options, patulous its function and utility, try to choose by the user, implementation client turns custom-built production. Another kind is focusing user demand, research and development has a technology only, develop the numerical control machine tool of specialization, offer comprehensive solution for the user. In intense market competition, advanced sex of the technology is not only get victory essential factor, the most essential is machine tool manufacturer can the demand of user of have a thorough grasp, offer simple and credible solution, create more value for the user. Should realise clearly, machine tool manufacturer and user are only advantageous can get ability to make technical change is true productivity quite. Of innovation having a technology only is by no means imagination of a castle in the air, without foundation can of research and development, build however on reliable individual technology, be a certain number of unit technologies is compositive. Innovation more those who cannot leave a machine tool to make the technology of the enterprise and experience is old accumulate, cannot leave an engineer to be studied assiduously. The talent of high quality is the most important resource that innovation and research and development have a technology only. Finally, the has a technology only research and development of innovation is returned should mature modular, can transplant gender and can recombine a gender, raise its economic benefits, make this new technology can serve for different user, application is won in different domain, make the research and development that has a technology only brings bigger gain, win bigger economic get one's own back.
