In the careful treatment of car mould, behoove of electric treatment machine tool is first selection. Machine the top class supplier of equipment as world report, the profundity of half century that Er of Swiss summer rice machines a machine tool to electric spark with its understands and study meticulously, the car mould treatment that can be high additional cost offers high quality solution! Excelsior solution is to the requirement of high-grade mould currently model face grain is clear, namely clarity of horn of even, edge, dimension cooperates exterior level off, surface roughness to close strictly seam. To achieve afore-mentioned requirements, study the mechanism that electric spark machines lucidly with respect to need: The mould dimension essence that should make sure place treatment goes out, outline is clear, the discharge clearance that asks report machines equipment must small, this solves the platoon below little space thoroughly with respect to need demand of performance of bits difficulty, servo is high and treatment makes the same score stability to wait for problem; to be in treatment is sophisticated model when antrum, the treatment difficulty on different way and treatment area differ very big. To assure efficient the consistency of clearance of report of transfer to a lower level, the handling time on requirement unit area should be equal. This uses translation technology to come to reasonable allocation with respect to need time, in order to digest this one inhomogenous. 1, the problem discharging bits that little space discharges is to solve below little space the problem that discharges centrally, xia Mier uses servo of digital complete closed circuit to have reliable control to the stability that little space machines, add the mechanical design with machine tool excellent itself and workmanship, make the machine tool is answered inside 2ms, make the displacement of 10 μ M inside 2~4ms subsequently, and this as it happens is finish machining in from discharge first the space that steady work place needs to pull open. Because electric spark treatment adopts the means corrode that discharges centrally to divide a metal, be in a discharge hind, the flange flange of discharge indentation and child of many report corrode can have pollution to clearance, bring about discharge the 2nd times to also happen around. Meet so local generation is here a chain of pulse discharge phenomenon, become till here quite cave. Because use little space discharge,be in in finish machining, laxity of enlarge of electric corrode child, local pollution will be more serious, pulse of follow-up of as a result evolves into electric arc, make cave the ministry is more coarse. Accordingly, xia Mier still used PILOTEXPERTIII expert system in the machine tool, this detects quickly every time pulse, have classification, statistic and judgement to them, use the method that cuts off energy pulse and change pulse parameter, improved the contaminative condition that centers discharge area effectively, to servo at the same time a clear minim picks up signal. The action overlay of servo of digital complete closed circuit and PILOTEXPERTIII expert system controls the length that centers discharge pulse to string together effectively completely. Pulse is strung together stop earlier, the flatness of place treatment face is better, but the issue that also brought efficiency on the low side at the same time. Normally, pulse strings together what just should remove arc fortunately to be stopped when the mouth, rate of this effectiveness for a given period of time is top. Of course the demand that this can press work plan face completely by handlers comes set. In little space finish machining, still must solve the problem that discharge bits reliably. Normally the practice is to use strong smoke oil to erode a bits, in order to make sure treatment is in steady state, but shed a meeting inhomogenously to cause the inhomogenous accumulation that cut bits, very big to machining the flatness after to affect, and erode strongly still can cause edge part unusual loss. In this respect, xiamierdi goes out settling way is: Carrying make great efforts on the knife. Carry in finish machining the time of the knife is commonly 0.

2s left and right sides, raise the discharge space that has 10 times about highly, be about to the knife is raised 0.

4~0.

6mm. In journey of the cutting tool inside so short time such small, it is very inaccessible high-speed. At the same time because space is little, still can form quite great fluid pressure in the instant that raise and restores discharge, be in commonly the retrorse pressure that 3000N can generate on the finish machining area of 500cm2 about. Speak force not to talk to go up at all not quite so high speed. For this Xia Mier is added thick transmission guide screw, use larger bearing, in order to bear higher retrorse power. Be in to assure at the same time of small area narrow obtain in flooey rough machining taller carry knife speed, the top speed of the machine tool was raised 2 times, be close to 3m/min, acceleration is amounted to 0.

5g. For example, when electrode sectional dimension is 2mm × 20mm, be machined model when antrum deepness is 100mm, use treatment of black lead electrode to need only 5.

5h, use treatment of red copper electrode to need only 8.

5h. Resemble drawing timing range so big severalfold, it is extremely tall to characteristic to low speed requirement electric spark form cutting very not easy. Nextpage 　 in fact, think on servo merely will compress carry the invalid time that the knife takes up is very finite. Another step that Xia Mier takes is to be below the control of PILOTEXPERTIII, make carry the setting of knife parameter differs along with treatment deepness and change, when beginning to machine namely, need not carry knife, or random servo carries knife. The doorsill that at the same time clearance detects also can be spent along with depth and change, when machining more shallow, unobstructed that discharge bits, get stuck a bit more loosely, so that allow more pulse discharge. These two measure are in of 40mm less than common narrow the effect in groovy treatment is apparent, efficiency can raise 1~2 times. 2, complex model the treatment of antrum to complex model the treatment of antrum, use translation technology to come to the reasonable allocation that time is Xiamier strong point. The ORB translation software that Xia Mier uses has following characteristics: ● instruction electrode along the requirement model face outline goes, at the same time essence of life repairs periphery and underside, this is very advantageous to controlling dimension. ● electrode can be in model extent direction servo and carry knife, make right model the discharge phase that every local essence builds antrum to go up to fall continuously continuously with groovy main shaft is compared distinguish without what, treatment is stable and reliable. ● is opposite by the speed of 1~2r/min report of week cincture banish, cutting of one layer upon layer ground, had not stayed in one place long, assure to discharge bits unobstructed. ● each to model the real time mental allowance of the face and translation speed link up with, make model the time of nap of antrum long side increases significantly than short edge, what compensated mental allowance thereby is inhomogenous. In mould treatment, return the treatment problem that can encounter minim antrum. Minim pitch is new to may be being compared Chinese user, but its are add the cost is extremely high. Its characteristic is dimension it is difficult that little, electrode makes small, mental allowance, reason asks to be in machine tool treatment, reduce loss as far as possible, raise successful rate. Developed special technology of one a complete set of for Er of this summer rice, detect clearance, treatment parameter set and servo delicacy adjust unified conformity, executive essence measures control. Be in much more imperceptible model in antrum treatment, the consistency that Xia Mier's report machines a machine tool to already achieved handling time does not exceed 5% , electrode amount reduces the result of 30% . 3, the die of hard alloy nicety that the die that eliminates the high additional cost with exterior current and accepted micro-crack is macrobian life. In the treatment process of die, of fluid of water agent job electroanalysis the main factor that destroying effect is influence die quality, its basically behave is: Stick in mouth surface receive an agent to dissolve, or the surface produces microcosmic crackle. Usually, microcosmic crackle meets the surface arise in electric treatment not only, although be in grinding treatment, if the operation is undeserved,also can arise. As a result of,this basically is local overheat, when eroding with working fluid, cause again local suddenly cold, cause exterior craze. Using average voltage to be the communication of 0 actually pulse power source and go with tall resistor after ionic water regards the job as fluid, electrolytic destroys action to already lowered lowermost rate. The contribution of company of summerly rice Er in this respect was to solve the surface the problem of microcosmic crackle, technical measure is: ● uses a height value, narrow pulse makes workpiece material is cast with gas phase piece. Because aerification is hot greatly prep above melts hot, can take away major quantity of heat, make workpiece surface heat does not rise. ● one by one undertakes effective pulse detects. Because PILOT-EXPERT expert system can control the energy that discharges centrally well, be in thereby prevent fracture of wire while the problem that also solved local overheat. Accordingly, the ply of layer of mould surface metamorphism after machine tool of summerly rice Er can assure finish machining does not have microcosmic crackle in less than of 1 μ M, have as same as elaborate grinding perfect point. Everybody knows machining center of cut of electric spark line, machining center has the function that changes a knife automatically, if do not have,this function can call numerical control mill only. The machine tool of cut of line of ROBOFIL2030SI-TW/4030SI-TW rigid numerical control that company of summerly rice Er rolls out can realize a diameter inside 45s 0.

25mm and diameter 0.

1mm/ diameter 0.

The exchange between 07mm electrode silk, we weigh reason for machining center of cut of electric spark line. This machine tool silk of two kinds of electrode falls completely at respective first-rate operating mode on call, trade is rapid and honest, can make sure the machine tool is run uninterruptedly. In Qing Dynasty horn or narrow in seaming treatment, use φ first commonly 0.

The electrode silk rough machining of 25mm two, change φ again 0.

The filament of 1mm has precision work. Below the circumstance that machines without core, can choose thick silk to shape the electric spark milling of aperture, with purify majority surplus, such already fast can save costly filament again. Same, after also can machining miniature antrum with filament, will machine seal wire aperture with thick silk or sell aperture. This kind of double silk construction of system is very compact, compare with original system walking along silk, take filar run and did not change, it is adscititious only library of silk of a thick electrode, made up in every transmission shaft two seal wire annulus, use the way that plays key and turn off a machine to choose to need work of which system walking along silk. Two seal wire canals that can swing lead to guider of a V diamond, after this guider one side wears away, can turn an angle repeats use. TW system does not limit the applied scope of the machine tool, this machine tool should change corresponding accessory only, can use φ likewise 0.

The electrode silk of 03mm has imperceptible treatment, yi Ke issues the ± that finish in the control of taper expert system the auger of 30 ° spends accurate cut. If there is the mould of 30% to need to be machined to go out in the workshop,small an internal angle is mixed narrow seam, choose machine tool of cut of line of switch of TW series double silk, want to increase the investment of 10% only, can get the get one's own back of 40% . Promote product function and service quality to acme it is Switzerland the way that Xiamier seeks. Regard one class as equational racing bicycle (what F1) component treatment uses what report machines a machine tool to appoint a partner, the figure of Er of Swiss summer rice often is accompanied one case with photograph of F1 racing bicycle!
