Development of car production industry is flying, one of its trends are, build new manufacturing base, meet new challenge. Especially South America and China, building many manufacturing base, the program of these base can get the influence of a variety of demand. Need construction to have the product line with innovation technology and agile height to ensure not only of crop rise (for example, leave factory everyday take the measure that use a car) , what must ensure product quality even is ceaseless rise. Accordingly, the new technology aspect with ongoing more significant hair, the innovate person that designs an industry to machinist Cheng people raised taller requirement, and dust mark (EMAG) PECM technology is opposite huge advantage is had when the complex component that difficult treatment material makes undertakes machining. Apply to tall difficulty 2 peace keeping are three-dimensional of structural work modular, can expand the PECM that machines a concept. The development of industry of auto industry, aviation and other industry department brought enormous challenge to process a trade, because of the progress of the development as these industries and technology, they need more and more difficult treatment data, and the new component that production more has figure of particularly intricate geometry. The new technology that makes these component place need must can assure efficient manufacturing technology, and assure absolutely craft integrality. The treatment that pays close attention to tall difficulty asks to be below this kind of setting, clearly, production plans personnel to must want hard to search new innovation sex to machine craft. At the same time people classics regular meeting asks: The new technology in domains of those machinist Cheng design whether the manufacturing demand that answers constant growth? To this one problem, the solution of one home appliance below round banner machines Aimakeji (ECM) technical company EMAG ECM GmbH gave out a special solution. Dust the is PECM technology that the experts of mark use them to say (" P " represent " nicety " ) , improved this technology further. The tall difficulty that they need from inside machining complex component process with respect to special attention at the beginning the task. Sale of technology of EMAG ECM of no less than is in charge of Richard Keller be said: "When machining high strenth alloy, a lot of users still depend on high speed milling and treatment of electric spark discharge up to now. But the inferior position that this technology has him, for instance, the tool wears away very big, and generation high temperature causes undesirable effect to material. In PECM, won't put in these problems, although go out,show these phenomena, the effect that causes also is negligible. In fact, this is the special advantage place of this craft. " this craft has the technology of high quality conspicuous advantage: Alloy of treatment high strenth (be called again " super alloy " ) and when material of other difficult treatment, the tool basically did not wear away apparently. Product surface is bright and clean degree very tall: Without burr, also damage without material composition. Is this how come true? Above all, EMC craft is in the process of cleared material, the movement is very downy. Workpiece serves as positive pole, the tool serves as cathode, in this polar between have electrolyte, electrolyte can come off metallic ion from workpiece. Because the cathode appearance of the tool represented expects workpiece form, because this is in the place with cleared need only,keep clear of material can. Adopt this kind of technique, the form such as a curved surface, annular passageway, groove or antrum room can be processed below the blame contact, case that does not get fuel factor effect, and can ensure highest accuracy. Mr Keller says taller efficiency: "This craft makes we can be produced most delicate with complex component. We had been ECM development PECM conciously, come true in order to ensure we can be on smaller and smaller part more the image of high accuracy, make the surface bright and clean at the same time degree more hasten is perfect. " this technology has two essential factor most crucial: Electrolyte passes the working space of workpiece, and the direction that electrolyte oneself flows. Keller explains: "On one hand, want to assure to be put in clearance really, in PECM, this space is particularly little; On the other hand, should ensure pulse is when treatment space is the least discharge. " -- the feed rate of electrolyte and overlay of mechanical and oscillatory photograph, this assured OK and efficient and accurately cleared material. "Turbine supercharger " give typical examples: Fast and perfect to each industries and user, the advantage of use PECM is best paradigmatic be auto industry " turbine supercharger " . Electroanalysis in rigid numerical control below the help of craft, the component that makes to a lot of high strenth material (especially the component of turbine supercharger domain) for, using more shorter, effective craft catenary to undertake machining is very ideal. A few conventional technology will need no longer, for example the purify burr operation after milling craft, because PECM craft can achieve energy not only small processing and also won't leave burr. The place before be like is narrated, use PECM, need not wear away for the tool almost worry about. This is meant often change with need the milling craft photograph of the tool is compared, the machine machine down time of this kind of craft shortens greatly, whole craft is stabler also, more make mistake not easily. To PECM, its advantage still has a bit more important: The surface is bright and clean degree. Mr Keller says for certain: "We can realize RZ 0.
Of 3 µm bright and clean degree (depend on material and decide) , this is surprising admirable surface roughness is worth. " it is of the market potential that how assesses this technology that tremendous skill sale is in charge of market potential? Such summary say Mr Keller: "I believe to use this technology, we can offer outstanding additional value for the client. For example, in the respect of fuel eject technology with unusually intense competition, the business that distribute a packet is searching a kind of plan to promote productivity all the time, improve their market position thereby, we can offer this. This craft is achieving perfect appearance bright and clean degree, the tool of cutty restoration time and lowest wears away the respect has admirable show, and these advantages will make the trend that will develop henceforth " . In fact, dust mark expert can offer complete PECM and ECM program completely in the light of specific client requirement. to achieve this one goal research and development comes out relevant electric pulse and mechanical and oscillatory compound processing technique and technology of patent power source. To component oneself dimension, the application of these craft accepts restriction scarcely. Even if 1, the workpiece of 000 Mm the following diameter, through dust the machine tool of electrochemical machining of linkage of much axis of rigid numerical control of mark and mature craft also can machine the treatment inside cycle to finish in cutty with extremely tall treatment efficiency, of the component that this ensured this innovation technology also can apply at the environment such as aircraft engine to ask difficulty is tall make, can part or replace milling of 5 axes high speed and craft of treatment of 5 axes and even 7 axes electric spark completely to undertake diffuser and integral Xie Panfu lamina of miscellaneous ala face, individual lamina or dish dish of for assembling blade tenon chamfer treatment of a depart.
