Operational safety and environmental protection

Operational safety and environmental protection
 Precision wire cutting Along with advance in technology and human culture development, the people are more and more high to the working condition improvement and the environmental protection request. The electric spark forming processing as a result of its own characteristic, can have the driving fluid splash, the smog, the noise, the electromagnetic radiation, the noxious gas inevitably in the processing process and so on the safety factor and the pollution, is noticeable to the operator personal safety and the environment harm. Therefore, for the guarantee electrical finishing industry sustainable development, must act according to “the green manufacture principle”, the realization resources most effective use and the reject threshold produces with the emissions. Should take following measure specifically:
        Precision wire cutting Seal engine bed work area. This is advantageous to the improvement driving fluid, the smog, the electromagnetic radiation and so on to the human body, the engine bed, the working conditions pollution, is advantageous in the operating process prevented receives an electric shock the danger as well as to the noxious gas centralized processing emissions;
 Precision wire cutting Vicarious technical utilization. For example, the environmental pollution which creates for the reduced use driving fluid, may in the guarantee processing efficiency, the processing precision, the processing cost as well as under the processing process stable premise, selects the pollution small driving fluid as far as possible, simultaneously should study, the development vigorously does not use the driving fluid the formed processing technology;

   Reject post-processing. The waste liquid, the waste gas produces which after the processing in must pass through processing to be able to discharge. Needs to point out specially, has pollutant reasonable processing to the processing process, not only is advantageous to the enhancement work security, the reduction environmental pollution, but also is advantageous in improves operator's working conditions, causes when the operator work the mood is happy, this regarding enhances the electrical finishing industry the social image and the market competitive power also is extremely beneficial.

Electric spark forming processing craft trend of development

Electric spark forming processing craft trend of development
 Through processes the mechanism to the electric spark forming the research, further promulgates the electric discharge process the inherent laws, and take this as the instruction, impels the electric spark forming processing craft to the high efficiency, the high accuracy, the low loss direction to develop, meanwhile should pay attention to the micro refinement processing aspect the development. 
(1) processing process highly effective
 Precision wire cuttingNot only the processing process highly effective manifests in through the improvement electric spark machining servosystem, the control system, the driving fluid system, the engine bed structure and so on, reduces the above factor to the electric spark forming processing efficiency influence, enhances, the precision work efficiency thickly in under the guarantee processing precision premise, meanwhile should reduce the non-cutting time as far as possible (for example programming time, electrode and work piece localization time, maintenance time and so on), this needs to strengthen the engine bed the automatic programming function, expands the engine bed online backstage programming ability, the improvement and the development suitable electrode and the work piece positioning device.
 In the engine bed maintenance aspect, should strengthen the engine bed the multimedia functions and the online help function, regarding the common breakdown, the operator may act according to the computer prompt realization trouble shooting directly, simultaneously this is also advantageous in strengthens the engine bed the feasibility and operator's operation skill.
 (2) processing process precision 
Precision wire cutting Through uses a series of advanced processing technology and the technique, at present the electric spark forming processing precision had the comprehensive enhancement, some has been possible to achieve the mirror surface processing level. But looked from the overall that, the vanguard technology insufficiently is also mature in the actual production application and widespread, therefore has the necessity comprehensive impetus to have the vanguard technology further consummation and to develop to the industrial production direction. In the guarantee processing speed, under the processing cost premise, makes the electric spark forming processing the precision level further to enhance, causes the electric spark forming to process into some major parts, the essential components finally processing way. At the same time, to processes the precision the weight not to be able to limit merely to the work piece size precision and the surface roughness, but also should include the profile the GDOP, deterioration level thickness as well as the microscopic crack, the oxidation, the corrosion and so on. 
(3) processing process micro refinement
Precision wire cutting  An electric spark forming processing important application domain is the narrow trough, the deep cavity, the tiny components processing, therefore the processing process micro refinement will be the next important development direction. The electric spark processes the mechanism and the conventional electric spark forming processing tiny is same, but has own craft characteristic: Each pulse electric discharge energy is very small, driving fluid circulation difficulty, stable electric discharge gap scope small and so on. Based on these craft characteristic, the tiny electric spark forming processing processing equipment, the driving fluid circulatory system, the electrode preparation and so on inevitably and the conventional electric spark forming processing has the very big difference. Therefore, needs key to study the non-mechanical action
 and the disturbance to the processing process influence and so on, further enhances the processing efficiency, the processing precision and the processing process stability.

The comprehensive impetus electric spark development direction

The comprehensive impetus electric spark development direction
For the comprehensive impetus electric spark forming processing equipment technology advancement, while uses the advanced control system, the engine bed structure design also needs further to consummate, its main development direction displays in following two aspects: (1) straight line servosystem application
 Precision wire cutting The electric spark forming processing equipment uses the straight line electrical machinery servosystem to be possible to cause the workability to obtain the distinct improvement, the concrete manifestation is:  May realize the axis direct translation, omits a guide screw nut transmission link, thus guarantee axis high speed movement;  Uses the straight line electrical machinery and the slide integration structure, may eliminate between the slide and the electrical machinery because of has the machinery lag in response phenomenon which the middle link causes, enhances the system the sensitivity, reduces the dynamic response time, the guarantee processing process stability;  The straight line electrical machinery servosystem mode of motion had decided its position examination link must use the straight line position feedback part, the realization not middle link direct position examination, thus constitutes an entire closed-loop system, the guarantee processing process high accuracy and the precision retentivity. At present, the straight line servosystem application in deep narrow, the small die space processing and a mould pressing components mold multi-cavity processing aspect has the obvious technical superiority. But, these technical superiority must realize truly, except must unify the electric spark forming processing electric discharge process characteristic, outside the solution straight line servosystem itself technical difficult problem, but also must solve a series of and the straight line servosystem necessary related technology, like translation system dynamic equilibrium, work table structure improvement and so on.
 (2) engine bed mode of motion improvement
 Precision wire cutting Breaks through the existing electric spark forming processing engine bed mode of motion the limitation, is displays its technical superiority, impels its industrial development another important way. The model modern machining technology development experience, may direct the human circular motion in the engine bed main processing forming movement foundation, specially uses the multiple spindle rotary system and many kinds of translation coordinating group synthesizes many kinds of compound motion way, adapts the different type work piece processing request, the expanded electric spark forming processing processing scope, enhances it in the precise processing aspect comparison superiority and the technical benefit. At present, many electric spark forming processing engine bed has made some improvements in the mode of motion, if Swiss Arch Company produces AGIF the MONDO STAR20(50) engine bed has the EQUIMODE function, can realize the spatial any direction hemisphere stable motion, this kind of stable motion function has the very high practical value in the actual processing. But the present electric spark forming processing engine bed additionally builds the mode of motion is also unitary, the application scope is limited. The electric spark forming processing must in aspects and so on processing precision, processing efficiency, processing scope obtain the significant breakthrough, an important development direction is to the engine bed forming mode of motion innovation and the diversification. Recently, Japan University of Tokyo -odd component doctor, increased Ze prosperous long Professor and so on to propose loss concepts and so on electrode, namely through to processed the way the reasonable plan, might cause the electrode to lose is at and so on the loss conditions, thus caused the compensation which the electrode lost to become extremely simple. This concept statement has provided the essential theory basis for the electric spark forming processing mode of motion improvement. Certainly, produces from this the engine bed structural change and the correlation technology theory research also must further the deep person and the consummation, even has the possibility to develop one kind of brand-new processing theory.

  Precision wire cutting In addition, the engine bed overall construction design must consider fully the environmental protection as well as a human machine coordination, with the aid of the advanced design method and the method (for example CAD, the finite element analysis and so on) carry on the comprehensive optimized design to the engine bed structure, enhances the engine bed structure fully the sophistication and the rationality.

Electric spark forming processing theory trend of development

Electric spark forming processing theory trend of development
Precision wire cuttingIn recent years, the electric spark forming processing basic theory research not yet made the substantive progress, although some scholars to the processing process electric discharge trace, the material eclipse eliminated the principle and so on to propose some new views, but obtained the significant breakthrough by no means in the electric spark machining mechanism research aspect. The more active research area mainly concentrates in the processing craft theory and the control theory aspect.
  Precision wire cuttingIn the processing craft fundamental research aspect, how does the research hot spot mainly is enhance the electric spark forming processing the surface quality and the processing speed, reduces the loss, the development electric spark machining scope, as well as exploration complex, tiny structure processing method and so on. Will apply through the research results in the production practice, will comprehensively enhance the electric spark forming processing workability. In the control fundamental research aspect, the intelligent control always is the research key. The domestic and foreign production new electric spark forming processing engine bed mostly has used the intelligent control technology, this technical application makes the engine bed operation to be easier, requests to the operator lowly. At the same time, the intelligence control system has from the learning capability, but the online automatic monitor, the adjustment processing process, realizes the processing process optimized control.
 Although the electric spark forming processing fundamental research in aspects and so on basic theory, processing craft theory, control theory all has certain development and the enhancement, but the processing craft theory, the control theory need to obtain the further full scale development, must have the breakthrough in the entire electric discharge process mechanism research. Therefore, the electric spark forming processing fundamental research trend of development will be further is discussing the processing craft theory and the control theory, enhances the electric spark forming processing workability and the processing scope, obtains the better control effect at the same time, key research electric discharge process mechanism.
 The electric spark forming processing mechanism research has not made the unprecedented progress the primary cause except outside the electric discharge process itself complexity, randomness, but also because the research technique and the method lack the innovation. Therefore, it is necessary to profit from other research area the success experience, directs the human advanced research technique and the experimental technology, the victory tradition research technique limitation, the deep person analysis and the revelation entire electric discharge process intrinsic essence, the establishment may reflect objectively the electric discharge process rule the theoretical model, instructs the electric spark forming processing craft theory and the control theory research, but the computer simulation technical possibilities realizes this process effective tool
 electric spark forming processing equipment structure improvement
  Precision wire cutting The model modern machining engine bed development experience, the electric spark forming processing equipment develops to the numerical control direction is a irreversible tendency. On the one hand should by the high accuracy, the high velocity, change into the pursue goal automatically, seizes the market by the technical superiority; On the other hand should consider fully the equipment the performance price compared to, through to the engine bed function reasonable localization, makes the structure improvement and the modular design, uses the open numerical control system, enhances rationality which the engine bed designs, provides by the lowest price and the enough function to the user may satisfy each kind of electric spark forming processing engine bed which the different processing needs.

  Modern machining technological development impact, before suits uses the electric spark machining a part of processing domain to substitute gradually for the machining way. But, the modern science and technology development proposed to the components manufacture precision a higher request, each kind of high performance material application is day by day widespread, simultaneously, some components structure tends to the complication, the microminiaturization, thinly, this all causes the machining technology to be restricted in certain processing domain application, but these are exactly the electric spark forming processing technical superiority, also is it has the existing space and the development potential reality basis.
