Foreword machines quality good, efficiency low all through the ages of tall, cost is the main demand of machine tool user to machine tool product, also be the main goal of research and development of machine tool product and direction at the same time. Live to be gotten in intense with each passing day market competition and develop, the design of the machine tool and maker people be in all the time make indefatigable effort for this. The treatment quality of the machine tool (contain dimension, form precision and exterior quality) problem, basically depend on machine tool equipment (contain tool and clamping apparatus) structural stiffness, geometrical precision, athletic precision and fixed position precision, still have ambient conditions of course (wait like temperature, vibration) control and assure. Accordingly, it needs to pass nicety of research and development, tall nicety and even the processing technique that exceed nicety and machine tool to solve. Manufacturing efficiency basically is by the spare parts from semifinished product the making cycle to finished product is measured. The making cycle of the spare parts includes the sex that is used at changing spare parts material directly (can) , (form) shape (like cutting figuration, heat treatment) needs time and blame treatment (do not change spare parts character namely) time (if the spare parts produces the place in the process,need await, deferent, detect, the time that holds tone, clamp to wait) two major composition. To reduce cutting handling time, need to raise cutting speed and feed rate above all. For this, people research and development technology of high speed cutting and machine tool, and be not handling time to shorten, people wants research and development more technical measure and equipment, include mechanical automation, numerical control flexible the machine tool that turn and product line (production system) with the numerical control that is in bitter fleabane break out to exhibit now compound treatment machine tool. Finished cost includes direct cost (pay of the bad news that be like material, specific power consumption, worker) with overhead costs (the depreciation cost that contains workshop, device, safe annulus insurance cost and administration fee) . To reduce cost, the question of here drag in is very much, have the problem of technical respect already, also have the problem of constituent management field, so need undertakes more integrated research will solve. The article does not draft, discuss impossibly also afore-mentioned all problems, think with respect to numerical control the development of compound treatment machine tool makes some of brief introduction talk about the view of bit of author only. The occurrence that combines treatment machine tool and numerical control are compound those who machine a machine tool is arisen usually, the production of a mechanical spare parts, arrive from semifinished product finished product, the course wants to use among certain (one plant or a variety of) add technique (be like punch, solder, cutting, grinding, non-traditional machining or car, mill, get, treatment of boring, tooth form) multitask foreword (outside the car in be like turning. Because different technique is having different treatment principle and characteristic, different treatment process is having different treatment goal and demand, accordingly they are using different treatment facilities to come true severally, reason is in traditional production, the production of a spare parts often has with respect to need a variety of, much stage is different treatment facilities will finish. This increased to the stage of equipment is counted and produce workshop not only cover an area of an area, increased the investment of the enterprise thereby, and because produce the workpiece in the process to need to await between craft and process equipment, move, examination and clip of outfit of new fixed position, affect treatment precision already, also increased to be not handling time not less. Have expert analysis, the 70% ～ that this part is not handling time to will occupy a spare parts to produce total cycle 95% the left and right sides, restricted those who manufacture efficiency greatly to rise thereby. Manufacture efficiency to rise, decrease be not handling time, people had early mix principle of a few treatment more as far as possible requirement close or similar treatment working procedure, and even different process goes to centrally or come true on a few a few equipment. The idea of compound treatment has to the spare parts after this kind of one second outfit is placed, the assorted treatment machine tool that appears in process of mechanical automation production and much knife are semi-automatic 6 horn (turn tower) lathe, it is its are reflected at first. Because modular machine tool is with a few general components (wait like workbench of pillar of head, slip, base, circumgyrate) for the foundation, deserve to ask with the treatment according to specific spare parts (working procedure of place of the figure that contains a part, dimension, treatment, treatment and precision) the fixture that designs technically, much axle box and partial tool market are installed and become, it is OK specific to some treatment, if the car starts top of housing body, box or gearshift casing to wait, implementation installs clip to complete process of all or major treatment, include mill plane, drill, bore hole, aperture of bore with a reamer, attack whorl to wait; And much knife is semi-automatic turn tower lathe, the basis is asked by the working procedure of treatment workpiece, turn in its after the cutting cutting tool that place of the mount on tower tool carrier requires, also can come true to hold clip specific to some axis or dish, cover a treatment that has all or major process, like turning inside, outside columnar face, end panel, groove, pour whorl of inside and outside of horn, treatment to wait. Accordingly, modular machine tool and much knife are semi-automatic turn tower lathe reflected the concept that centers working procedure to have compound treatment, decreased greatly to be not handling time, improved productivity significantly thereby. But, these machine tools all belong to rigid automation category, when treatment object alternates, equipment also must change or readjust is configured, needs time and capital investment are larger, because this appropriate is used at the medium, big batch of onefold breed spare parts to produce, and the sheet that does not suit to be used at much breed spare parts produce with small lot. Appear along with what a move in chess or a movement in wushu charges a machine tool and numerical control technology (contain numerical control servo, functional component and process designing, software) of day of beneficial development and function rise, what enhanced numerical control machine tool greatly is flexible automation ability, add the progress of individuation of mechanical and electrical products, the demand that the market produces to much breed small lot increasingly grow in quantity, machine for numerical control machine tool thereby compound the development that change offerred wide world. In fact, be in early after numerical control machine tool comes out before long, 1958 mill of the first boring kind the occurrence of machining center, compound treatment already became the main technique of numerical control machine tool to develop one of way, at this late hour, the numerical control that had appeared to make much sort is compound machine a machine tool, have the demand of production of efficient low cost in order to get used to current market to spare parts of much breed small lot. The class of compound treatment machine tool reachs numerical control its are representative product numerical control is compound treatment machine tool is with contemporary and flexible the numerical control machine tool of automation is a foundation, with modular machine tool and much knife semi-automatic turn of tower machine tool " center working procedure, outfit to place implementation multitask order compound treatment " what the concept is directive development to rise is new machine tool of a kind of numerical control. Install clip hind last time in its when workpiece, what through be opposite treatment requires a tool (cutting cutting tool or mould) change automatically, can press numerical control program automatically ordinal the treatment of a variety of working procedure in the many working procedure in having same technique or different technique, decrease thereby be not handling time, shorten treatment is periodic, achieve the goal that improves manufacturing efficiency. Accordingly, the compound sex that compound treatment machine tool machines from its comes to numerical control cent, can divide for working procedure compound model with craft compound model two kinds big. Former and consistent the boring mill like center of machining center, turning, grinding center, the many process that can complete same technique only on a machine tool are machined; And latter is like a car - mill is compound center, car - grind compound center, turning - center of laser beam machining, can complete the many process of same technique not only on a machine tool, and the many process that can complete a variety of different technique. Be like a car - mill is compound center, already a variety of working procedure of achievable turning, can finish mill again, auger, a variety of working procedure of the craft such as boring, tap, seem mixes lathe of a numerical control one Taichun is small-sized machining center is compound together. If from numerical control the machines structure of object, machine tool configuration means of compound treatment machine tool is mixed functional characteristic special a note of the ancient Chinese five-tone scale will divide, numerical control is compound the class that machines a machine tool is very much. Press treatment object cent for instance, have face swing tower of treatment, prism of treatment with complex body (combine by swing tower and prism face) of treatment. Do not plan to be added with respect to class detailed here discuss, be opposite only below a few common and commonly used and have a few kinds of representative numerical control compound treatment machine tool makes brief introducing. 1.

Boring mill machining center: It is a foundation with mill of ordinary numerical control, boring machine, deserve to be mixed with corresponding knife library change the functional component such as knife device and control automatically to the system develops and be become, like kind of one 3 axes linkage pilot vertical, horizontal is mixed mill of boring of dragon door type machining center, graph the 1 vertical machining center that is production of American Ha Si company, it in order to machine prism spare parts (contain casing, housing and board piece etc) for main target, workpiece installs clip hind last time in its, be chosen from knife library by machine program through manipulator and change the cutting tool on main shaft, can undertake to the horizontal of workpiece 1-3 dimension milling is machined, be like curved surface of outline of mill plane, mill, mill antrum, and bore, bore hole, the treatment working procedure such as tap. This is the commonnest and commonly used, also be the numerical control that prevailing prism treatment uses compound treatment machine tool, but the craft ability of this kind of machine tool is limited, the outfit clip that is like workpiece can be in only perpendicular undertake machining within a face of main shaft, to casing on perpendicular hereat the other plane of the face cannot be machined, cannot go up to workpiece more the plane that is in aleatoric space position undertakes machining. As similar as this, although the horizontal machining center of 3 axes linkage can machine casing through the dislocation of workbench 4 flank, but cannot machine casing however end face. Graph the vertical machining center that Ha Si company of 1 United States produces 2.

5 treatment and machining center of 5 axes linkage: To overcome common boring mill machining center puts afore-mentioned craft limitation that be in, people is in with common boring mill machining center is a foundation, it is OK to will secure the main shaft head that point to to be changed so stand, the main shaft head that lies to be changed automatically and use but circumgyrate is graduated workbench, such machine tool can fit the requirement of clip in workpiece, obtain 5 (like casing kind workpiece) the process capability of more even face, become face and even many 5 machining center. If common boring mill the main shaft of machining center changes a know exactly about sth to accuse single pendulum (A or B axis) or double place (C and A or B axis) electric main shaft of the function, or deserve to go up on workbench the workbench of numerical control circumgyrate that has function of C axis or C and B axis roll, still have system of corresponding numerical control of pilot of 5 axes linkage of course, criterion the machining center that the machine tool becomes 5 axes linkage with respect to development. Graph the machining center of vertical of 5 axes linkage that companies of 2 the Ke Lang that it is rice produce. Thirdly linear axis allocates go up in main shaft head and workbench, two rotors are finished by circumgyrate workbench. The function of face or many 5 machining center and common machining center distinguishs the machining center of vertical of 5 axes linkage that the graph restrains bright company 2 meters to basically depend on: It can be in not only the full treatment working procedure that hangs down to be able to finish common machining center within the plane of main shaft continuously, still can be in mutual and as perpendicular as this plane other plane (outside the side holding clip that divides work) inside finish same treatment job. And the full treatment function that machining center of 5 axes linkage has many machining center already and ability, the face that still has places of pair of space of the random on workpiece (planar, cant or curved surface) the capacity that has the mill, boring, treatment that get. Its craft range is so wider, capability is stronger. .

Turning center: It is with ordinary numerical control lathe is a foundation normally, match with one or more have much knife turn to tower tool carrier develops and be become, machining an object basically is an axis kind and dish set kind wait for swing tower spare parts. As a result of swing tower in the part that has half left and right sides about, divide outside basically needing turning to machine, the milling that still wants a part, get cut and the treatment such as tap, to be in accordingly a lathe installs clip to be able to be opposite last time swing tower have all or major treatment, of turning center turn on tower tool carrier, besides of turning cutting tool outside, still can the gyral dynamical cutting tool such as mount milling cutter, broach and tap, and machine tool main shaft has numerical control accurate graduated C axis function and C and Z axis or the function with C and X axis linkage. Centers of such a turning can resemble lathe of ordinary numerical control can be opposite in that way not only swing tower surface of inside and outside (contain columnar face, cone, curved surface to wait) , end panel undertakes turning is machined, still can use whorl of car of function of C-Z axis linkage, the X that uses function of C axis graduation and tool carrier or Y axle control and the motivation on its rotate cutting tool undertakes deviate swing tower the bore of central line and milling, expanded greatly thereby numerical control lathe is compound the ability of treatment. Graph 3 it is center of SPINNER company turning. But, to the turning center of odd main shaft, no matter its are versed in how skill force expands, inextricability also swing tower the reverse side that outfit clip plays (former outfit places end) fabricating problem, the inadequacy that this is existence of center of turning of odd main shaft and the reason that develop new-style turning center are in. The turning center of company of graph 3 Spinner 4.

Center of turning of double main shaft: What exist to overcome center of turning of odd main shaft is insufficient, the design maker of the machine tool adopted the foundation that is in center of turning of odd main shaft to go up, add to be with original owner axis on axes the deputy main shaft of contraposition and a many knife deputy turn tower tool carrier, the turning center that makes the machine tool becomes double tool carrier of double main shaft (graph 4) . deputy the function that synchronism of two main shaft turns with Xiang Xuan and has C axle control, deputy main shaft still can move along axial Z, be in with collect the part that right end is completing to machine on main shaft. Collect of deputy main shaft is over workpiece is retreated be opposite to the cutting tool that goes up by deputy tool carrier namely after proper place its Zun Duan (original mix holds end) undertake machining. , deputy two tool carrier are located in respectively, of deputy main shaft on, lower part, can part alone process designing works, accordingly center of turning of double main shaft, double tool carrier can is opposite swing tower implementation installs clip to complete comprehensive treatment. Graph center of turning of 4 pairs of main shaft 5.

Car - mill is compound machining center and mill - the vehicle is complex machining center: Former it is a foundation with the turning center of odd main shaft or double main shaft more, will go up turn instead of tower tool carrier deserves to have knife library and the milling head of electric main shaft of the orgnaization that change a knife and into, the GMX Linear series that if campstool of Japanese hill Qi restrains a company,company of Integrex-IVST series of production and German DMG produces (graph 5) Che Xi is compound machining center, milling head of its report main shaft can move along axis of X1, Z1 already, still have the roll of Y axis journey and B axis. Latter -- mill, vehicle is complex machining center is much with the mill boring of face or 5 5 axes linkage machining center is a foundation, will rotate to the revolving stage that workbench changes rotate speed to get drive of much pitching moment electric machinery higher than common revolving stage develops and be become. No matter be former,still be latter, both the function that all has numerical control lathe and machining center at the same time, it is to satisfy have swing tower already special a note of the ancient Chinese five-tone scale, have prism again the treatment of the complex form spare parts of a note of the ancient Chinese five-tone scale needs and develop especially those who rise. But those who be worth to carry is: In mill - when the car executes turning mission on compound machining center, the revolving stage of drive of pitching moment electric machinery uses the workpiece main shaft that serves as lathe, and the milling head main shaft that regards milling as machining center so, must chain now and mount lathe tool is used as the tool carrier of lathe. The car as a result of linkage of much axle control, 5 axes - mill center and mill - vehicle center can complete all sorts of turning process already, can finish all sorts of getting again, the working procedure such as mill, boring, tap; Can machine swing tower respectively not only with prism, and suit to process the mixture system with very complex form particularly, of its craft limits wide with ability strong, it may be said is current cutting the person above average of compound treatment machine tool. The center of mill of Linear series car of company of graph 5 DMG 6.

Grinding center: It is with numerical control cylindrical grinder is become for fundamental development commonly. Adopted two main technology measure normally for this; (1) workpiece main shaft changes appliance to have C axle control and chain electric main shaft of the function; (2) emery wheel head is worn use double slip is mixed or have B axis to swing of the function turn head of tower type emery wheel is worn, in order to install the emery wheel of 2 above (be like comfortable at outside circle and inside round grinding uses, grinding of face of comfortable Yu Duan and figuration grinding use wait) , in order to satisfy the need of different grinding working procedure. The X axis function that the Z axis that because numerical control cylindrical grinder has control commonly,workbench left and right sides moves and emery wheel head wear around to move, such swing tower install clip hind last time in the machine tool, not only can the circle outside grinding, inside end panel of shoulder of round, stage, plane of the grinding on the outside face in workpiece mixes the function of C axle control that still can use workpiece rod much arris face; The linkage that passes X axis and C axis controls grinding all sorts of circle surfaces and blame circle surface; The linkage that passes C axis and Z axis controls grinding whorl; The B rod that uses emery wheel head to wear swings grinding the taper seat of all sorts of different taper. Graph 6 it is STUDER company be in the grinding center that is fundamental development to rise with numerical control cylindrical grinder. Graph the grinding center that 6 STUDER produces 7.

Car - grind compound treatment machine tool: It is to be on the base that lathe of contemporary numerical control uses commonly, to get used to the swing tower part with certain classics hard temper by dipping in water, wait for dish of treatment that covers kind of part to ask like gear of main shaft, drive and bearing annulus and development rises. Deployed unit of grinding of emery wheel of high speed CBN and corresponding grinding to measure on numerical control lathe normally for this with control system, if company of the Schaudt on EMO 2005 exhibits KAIROS car - grind compound machining center (graph 7.

A) the convert type car that exhibits with EMAG company - grind compound machining center (graph 7.

B) it is example. The KAIROS machine tool of standard type configures 2~3 commonly slip, use what head of main shaft of grinding of installation high speed and car, milling cutter provides to turn respectively tower tool carrier. 400mm of Φ of emery wheel diameter, turn tower tool carrier has 8 knives, the machine tool can be used at turning and grinding to be as long as the axis of 1000mm kind spare parts. Car of EMAG convert type - the main shaft that grinds compound treatment machine tool (take work) head wearing is in upper part, make X and Z axis motion, the lower part that main shaft carries deserves what to can install lathe tool and grinding spindle turn tower tool carrier, they make graduation rotate only and do not make shift, the machine tool can finish turning to machine working procedure like lathe of ordinary numerical control already, also can finish grinding to machine working procedure like cylindrical grinder of ordinary numerical control. Basically use at temper by dipping in water hard dish, cover kind of spare parts treatment. The convert type car that the KAIROS car of A) Schaudt grinds central B) EMAG grinds a center to pursue 7 cars, grind compound treatment machine tool to be mixed besides afore-mentioned class outside structural type, compound treatment machine tool still has numerical control lots and lots of other kind and structural configuration type, did not introduce one by one here. Numerical control is compound the development trend that machines a machine tool and direction from in recent years home, outside in light of the new product of held numerical control machine tool that exhibits on exhibition of machine tool product internationally and concerned review analysis material, the main technique of compound treatment machine tool develops numerical control trend and direction, relatively centralized performance is as follows: 1.

Continue to enlarge the compound process capability of machine tool of only station numerical control. Adopt pair of process and working procedure optimize (if incorporate, simplify treatment process) , of cutting tool structure improve (if use assorted cutting tool, special cutting tool to wait) the amount that reduces craft, working procedure and place to require a tool; The innovation that passes machine tool structure and configuration (the main shaft head that is like much axle control, much knife turn tower type tool carrier and emery wheel head are worn etc) , the reserve of the nimbleness that increases a machine tool, cutting tool is measured and offer automatically (change) the ability of cutting tool, raise a machine tool thereby the ability of compound treatment, those who make have more more spare partses, technology can hold clip last time in a machine tool with working procedure treatment is finished later. The much process that there were all sorts of onefold technologies not only now for example is complex machine a machine tool, wait like machining center of turning center, milling center, grinding center, punch, and still had a car - mill compound, car - grind compound, turning - make a tooth-like part of anything compound and even cutting treatment and laser beam machining punch and drill are compound, complex the multitask foreword that waits for a variety of craft is compound machine a machine tool appear and develop. The double main shaft that Japanese MAZAK company rolls out Integrex- Ⅲ St and series of Integrex- Ⅳ St recently the car of 5 linkage - mill is compound machine a machine tool, besides having function of turning, milling, still have round grinding of crankshaft treatment, gear hobbing, inside and outside and laser to quench wait for treatment function. 2.

To improve productivity further, especially only station is compound machine a machine tool yield rate, compound treatment machine tool is in numerical control to much main shaft, much tool carrier, multitask way develops. Be like the new product DZ15KW of company of the Chiron on EMO-2005, DZ18W, DZ12KS is the machining center of double main shaft; The TWINFLEX MD of MAKINO company is double lie main shaft or double the machining center that establishs main shaft, have the manipulator that change a knife each; The car of 3 main shaft that the MC726/MT of the Integrex 300IV of MAZAK and German STAMA all is two turning main shaft and main shaft of a milling - mill is compound machine a machine tool; The V160D of German INDEX company is double main shaft, double turn the lathe of convert type numerical control of tower tool carrier, can machine two same parts at the same time; The Super NTY3 of Japanese NAKAMURA-TOME company is double main shaft, 3 turn the car of tower tool carrier - mill machining center, the TNX80/65 of German TRAUB company is double main shaft 4 turn the car of tower tool carrier - mill center. These machine tools use the structure of much main shaft, much tool carrier, dividing a share is outside stemming from the need that machines craft and working procedure, many it is to stem from use much main shaft to machine many same parts and much tool carrier to undertake to same part multitask foreword is machined at the same time at the same time, can go up in handling time mutual coincide, thereby can twice land improves compound treatment inside time of machine tool unit yield achievement. The machine tool of because these are much main shaft, much tool carrier is essentially be equivalent to two or compound treatment machine tool sets many identical numerical control together, just used collective lathe bed and by same numerical control system undertakes be controllinged. The totle drilling cost of the machine tool of odd main shaft that nevertheless the cost of machine tool of much tool carrier wants a many such main shaft to become independent than much stage wants petty gain, still be economical economically so. Graph the machining center of vertical of DZ15W double main shaft of 8 Chiron 3.

Develop to large direction. Because one of main shaft advantages of compound treatment are to reduce a spare parts to be in,multitask foreword is mixed in process of much craft treatment reinstall for many times adjust the time with clamp, the place that because large part is a structure more commonly,complex, requirement machines and working procedure more, installation locates also relatively the spare parts that take time gives or take a lot of trouble, use numerical control machine tool to undertake compound treatment is compared so advantageous. Develop the treatment of large product to need to get used to large and heavy mechanical industry accordingly, compound treatment machine tool has numerical control to large the tide that turns development. If be on CIMT-2005, the type of MC2000 dragon door that limited company of hi-tech of Beijing Electromechanical courtyard exhibits 5 machining center, workbench face is 1250mm × 2200mm; Group of machine tool of plain of the Qin Dynasty exhibits car of VTM-180 Shuangzhu vertical - mill center, diameter of the biggest turning is Φ 2400mm. On JIMTOF-2004, of the Japanese 5 axis linkage that big company rivering bend exhibits use diplodocus door mesa of machining center job is 2000mm × 3000mm; The mill of car of dragon door type that Germany covers with tiles the company rolls out Delixikebao recently is compound machining center, workbench range breadth amounts to 4500mm ～ 6500mm. This year on CCMT-2006, the Schiess VMG 1 that Inc. of Shenyang machine tool exhibits.

Car of vertical of 28 dragon door - mill is compound diameter of the biggest turning amounts to treatment machine tool Φ 3200mm, turning height 2500mm; The 4000mm of × of 800mm of Φ of ＝ of length of treatment diameter × of center of SSCKZ80/4000 large turning; The type of door of XHZ2320/4-5 axis dragon that joint-stock company of Guilin machine tool exhibits machining center, workbench face is 2000mm × 4000mm; The 5 axes that group of 2 machine tools exhibits decide Jinan mill of bridge type boring machining center, workbench face also is 2000mm × 4000mm to wait. This explains with respect to enough numerical control is compound treatment machine tool is large the development tide that turn. 4.

To the structure modular the way that can recombine quickly with the function develops. Because the structure is modular,be the base that compound treatment machine tool expands numerical control quickly, and the function of compound treatment machine tool can recombine numerical control quickly is its can answer market demand quickly, and can the fundamental condition of market of race to control, because a lot of famous machine tools make this abroad,the manufacturer is this already and try hard research and development. In fact, the manufacturer with a few advanced technologies (the Mikron company that is like Switzerland, american Ha Sihe breaths out Ting company, german DMG, EMAG and TRAUB company) a lot of products already realized the design with modular structure, trying hard to the respect that how realizes a function to recombine quickly. Epilogue: The place on a few view and proposal put together is narrated, because numerical control is compound,a variety of working procedure plant collect of treatment machine tool at most therefore craft at a suit, all or major treatment can be completed on its after workpiece holds clip, the number holding clip that this reduced workpiece not only and a lot of blame handling time, rose to machine precision and efficiency, and of the equipment platform number that still reduced a spare parts to machine place to need and manufacturer room cover an area of an area, also reduced the investment of the person related the enterprise, money, content thereby, reduced manufacturing cost, raised the economic benefits of the enterprise, accordingly, compound treatment machine tool affirms numerical control is numerical control machine tool and one of significant progress direction of production technology. From theoretic tell, craft of treatment of compound of place of machine tool of a numerical control and working procedure had healed more more, but always be finite actually. Because want to be wanted the correlation between compound craft and working procedure and requirement by specific place, and realize compound treatment to be in technology (contain soft, hardware design, carry out) of a lot of element such as the possibility that go up and economically rationality restrict. Accordingly, enlarging numerical control when the compound ability of compound treatment machine tool, the research that must have thorough technology and economic side to wanting compound craft and process is analysed, avoid by all means begs ground of big demand perfection to enlarge compound process capability blindly. current technology level, onefold craft (like car, mill, grind etc) multitask foreword is compound treatment is in economically more reasonable, on the technology also relatively come true easily, and the much process that crosses craft is complex treatment, the mill that remove a car (or mill car) it is more mature that compound, car grinds compound processing technique outside, a type of local school in ancient times of other much craft multitask are compound, if turning, laser beam machining is compound; Treatment of milling, electric spark is compound; Of the process that make a tooth-like part of anything completely compound wait, carry out the difficulty with rise to still have certain, basically be alternate with craft and working procedure in the process, what require cutting tool (or tool) how be exchanged automatically and locate the structural design problem of clamp is concerned, still remain at further research and development. To quicken our country numerical control the development of compound treatment machine tool, the proposal should strengthen the development of machine tool of our country numerical control in the round above all, especially the component of function of numerical control machine tool of high-powered, high quality (embody numerical control system) research and development; Study energetically at the same time and develop the craft module that applies to compound treatment to use, if carry the head of turning main shaft of the workpiece of fast and automatic clamp of C axis function, have C and B (or A) of axle control function change to be worn with the head of milling main shaft of clamp cutting tool and emery wheel head quickly, use at be not cutting cutting tool (head of the emery wheel that uses like grinding, laser beam machining, ultrasonic head, all sorts of measurement first class) tool library and change automatically device. Because these are development numerical control the fundamental component of compound treatment machine tool. Numerical control is compound though develop on the foundation of numerical control machine tool in different type and treatment machine tool comes, but good numerical control is compound treatment machine tool is not absolutely, also cannot be by only station the numerical control machine tool of different process or craft goes all out simply to install and be become, and must be to be in optimize what development already innovated to come out on processes of some conventional technology working procedure and the foundation that machine tool structure deploys type. So, issue the numerical control that has our country own intellectual property for production product of compound treatment machine tool, the research and development that must strengthen structure of new assembly of pair of new technology, new method, new cutting tool and machine tool, what must strengthen the science and technology that makes a technology to machinery to innovate namely is devoted, and the research that in a planned way, organically has fundamental technology and applied technology photograph are united in wedlock. Such numerical control that we just develop our country better likely are only compound machine a machine tool and improve the mechanical production technology of our country to update higher level to.
