The current situation of industry of 1 machine tool and foreground come nearly 30 years, as the progressively development of reforming and opening, chinese economy got very great progress. New product of very much new technology is pounding the market of Chinese home ceaselessly, brought about manufacturing industry to process trade swift and violent development, this gives a machine tool the industry extend and progress brought tremendous turning point. Machine tool industry of China from before a large number of production that what give priority to body with Bench Machine Tool, to now large and medium-sized machine tool, the proportion of product of whole set thread increases stage by stage. And, improve of craft ceaselessly as treatment, the demand that machines speed to machining precision is higher and higher also. At present the manufacturer home of industry of countrywide machine tool has on 10 thousand, it is mostly among them in order to produce in low end the enterprise that rough machining gives priority to. But, mix as a result of material in recent years of price of the sources of energy shoot up, the money that national institute takes is constrictive the element such as policy, add those who cause downstream trade fast decelerate, profit decreases. And the product that has high additional cost is added fast continue to maintain increase production, profit adds considerably, the competition of prospective industry will be inevitable change market of face high end. So, more and more enterprises had begun to realize, machine tool industry of China, be in adherence low end domain while, should reach production respect to extend in the development of high-end product more, is not so more that support imports equipment. The equipment with different basis of machine tool industry, use electric product special land is extensive, from sheet piece machine, PLC, fixed position module, numerical control system controls a system to wait to have to motion involve, have manufacturer more the electric equipment of own research and development. A few high end use a field, be like the grinder of high accuracy, rotate knife library, servo punch sends makings plane, automation line of automation private plane, have a few special demand to control and craft, these are not common pulse happening the product perhaps locates the product is OK and simple corresponding, more and more use motion control a product. Motion of 2 3 water chestnut is controlled and servo drive respect has servo product brief introduction substantial product line, OK and corresponding the machine tool equipment of all sorts of types. In athletic controller respect, from 8 axes synchro control arrives 32 axes synchro control, till 1280 axes synchro control has corresponding method. And, the athletic controller of 3 water chestnut passes different operating system software, supportable application of different machine tool industry. Be like the operating system of SV13, with the programming language of appropriative SFC, the grinder device that uses at high accuracy more has the action of interpolation, and the operating system of SV22, support a language with machinery, apply extensively in the machine tool equipment of synchro control of high accuracy of much axis high speed. In servo product side, have all sorts of inertia order and degree, the fixed position that satisfies all sorts of equipment controls a demand, and go up from power for, small to 50W, have mature product to 110kW greatly. To the demand of 110kW above, also all sorts of corresponding meanses realize control. Below the application of product of 3 3 water chestnut in machine tool industry and characteristic we with 2 clients case, will introduce motion of 3 water chestnut to control a product to apply in machine tool industry. Punch of ① high-powered servo and send had said before makings system, the machine tool industry henceforth will forward market move of high end, so right of the machine tool compound change intelligence raised taller requirement, it is with common punch device exemple, before equipment is good punch work is taken by artificial operation take, as rise of cost of domestic labor power ceaselessly now, replacing artificial operation by the machine will be an inevitable trend, so high-powered punch machine tool will by send automatically makings the operation that takes makings system to replace a person. So how does punch equipment run different punch curve according to different workpiece, send makings system how to cooperate with punch system photograph, will place of high-end punch equipment needs to consider how assure the security of the mould to wait, controller of undoubted use motion is best chosen plan, product of controller of its requirement motion can ask to change according to different workpiece treatment punch curve, send the synchro control of material equipment and punch equipment. Behavioral essentials is as follows: This system is mixed by servo punch of form a complete set send makings machine place to form, punch is finished in punch while, send makings system to undertake sending the movement of makings, working area is not in punch head, finish send makings, and send makings system return initiative position, await punch to undertake punch again, ordinal loop, this system asks the movement that sends makings system movement and punch can cooperate each other, have synchronous control. This equipment needs punch axis, deferent axis 6. The servo punch of this system and sending makings plane is by the athletic controller of 3 water chestnuts QD series MOTION is undertaken controlling, the system configures a structure to be as follows: Because this equipment used product of controller of the newest Q170M of 3 water chestnut motion, can accuse 16 axes at most, if will need henceforth,control the word of more punch so, need to add servo product accordingly only already but, control product need not increase. Additional, this motion controls power supply of the buy inside the product, PLCCPU and motion control CPU, managing one part cost of the client. In the meantime, it is based on the substrate of high speed communication of IQ Platform, implementation corresponds without seamed link, the network of bus line of SSCNET Ⅲ servo that 3 water chestnut used to be developed independently between athletic controller and servo amplifier, make the clock frequency of each axis is achieved consistent, made sure all axes accept same statement to begin an action in same hour. For the equipment with these very high to this kind of synchronous requirement character, it is very necessary function. Additional, this motion controller uses fiber-optic bus line to join, speed of network news report more achieved 50Mbps, not only increased interference rejection capacity, reduced the wrong rate that spot wiring manipulates, the high speed that still can realize magnanimity to dominate data is transmitted. Nextpage can dominate servo punch and the action that send makings orgnaization at the same time through controller of a motion. Use the rigid construction program with 3 peculiar water chestnut, it is OK to write a program simply the movement of will strong pressure head and send the union with each perfect axis of makings to be together, realize the requirement of synchro control. Move through adjusting those who issue the main shaft in the graph, with respect to OK and simple control all axes complete respective action according to fixed sequential. In the meantime, the client can pass athletic controller, according to actual punch workpiece, choose suitable punch curve, reduced the to the mould loss in punch process, prolonged the life of the mould. If the client has facility of much stage punch, can pass controller of a motion more (most 32 axes) the action that dominates many compressor, more managing to the client electric the cost that go up. Craft of the muller inside high accuracy of the muller inside ② high accuracy pursues as follows: Muller is used at machining bearing wall inside. Basically use two axes interpolation to move when treatment. Among them X axis does constant speed to move on radial direction, rate of the minimum when treatment is 0. 2 μ M/s. Z axis is in charge of grinding annulus reciprocate, cheng of its head office is 410mm, highest frequency is 520 times minutely. This system used controller of QD series motion and the MR-J3-B series servo that answer relatively with its. The resolution of electric machinery of this series servo achieved 262144p/r, the electric machinery of high resolution satisfied the fixed position requirement of the high accuracy to the machine tool. Besides, this servo is advanced shake automatically control a function, can restrain what what in machining a process, produce automatically to shake, reduced the error of treatment, and reduced spot hand move adjustment operation, went to the lavatory of process designing personnel debug. The dimension of electric machinery more decreased than before 23% , reduced the installation size of mechanical equipment greatly. Finally, because all parameters are managed by athletic controller, so once appear the word of the attaint of servo product, need to change only corresponding servo product, and need not other the change of any parameter and program. Because this equipment uses the servo control of the Q172H motion controller of 3 water chestnut and J3-B series, can realize high accuracy ground to grind Xiu Sha annulus, with implementation grinding workpiece more high accuracy. 4 summary are mixed in special type machine tool private plane more and more today, the motion of 3 water chestnut is controlled and servo product cuts a figure in machine tool industry, more body reveal his to be in the advantage of respect of high accuracy of synchronous high speed. Product of 3 water chestnut will be mixed with Chinese manufacturing industry treatment industry grows together, make jointly better tomorrow. CNC Milling
