【正文】 d to distribute time reasonable to digest this uneven phenomenon。 Better solution The high demand of upmarket die in the current is that the die have clear surface texture, roughness surface, uniform roughness, clear corner, and its size can be met strictly。 Therefore, the machine Chamier also used PILOT EXPERT III expert system, The site for the installation of highgrade correctly and quickly detect a pulse each of them classified, Statistics and judgment and cut energy use and change the pulse of pulse parameters, improved the situation of concentrate discharge of pollution effectively, meanwhile servo system will accept a clear trace signal rebound 。 In this regard, the solution Chamier proposed is that do effort to lifting。 For example, when the electrode section size of 2mm 20mm, processing cavity depth of 100mm, processing of graphite electrodes used in only hours, using copper electrode processing just 。 ●Discharge to the surrounding in turns according to the speed of 1~2r/min , cutting layer by layer and would’t stay too long in a piont。 3, the elimination of surface microcracks Now the accepted high valueadded Die is longevity of carbide precision die。 As much higher than the thermal gasification melting heat, most of the heat can be removed and the Temperature of surface of workpiece will not up。1mm again changed the filaments for finishing。 under the control of the Taper expert system 。 小間隙放電的排屑問題 為解決在小間隙下集中放電的問題,夏米爾采用數(shù)字全閉環(huán)伺服系統(tǒng)對(duì)小間隙加工的穩(wěn)定性進(jìn)行可靠的控制 ,加上機(jī)床本身精良的機(jī)械設(shè)計(jì)和制造工藝 ,使機(jī)床在 2ms 內(nèi)響應(yīng),隨后在 2~4ms 內(nèi)做出 10mm 的位移,而這正好是精加工中從首次放電到穩(wěn)定工作所需要拉開的距離。當(dāng)然這完全可以由操作者按工件圖面的要求來設(shè)定。為此夏米爾加粗了傳動(dòng)絲杠,采用更大的軸承,以承受較高的反向力。 復(fù)雜型腔的加工 對(duì)于復(fù)雜型腔的加工,采用平動(dòng)技術(shù)來合理分配時(shí)間是夏米爾的強(qiáng)項(xiàng)。為此夏米爾開發(fā)了一整套特殊工藝,將間隙檢測(cè)、加工參數(shù)設(shè)定和伺服靈敏調(diào)節(jié)統(tǒng)一整合,實(shí)施精量控制。由于氣化熱大大高于融化熱,可帶走大部分熱量,使工件 表面熱不起來。在無芯加工的場(chǎng)合下,可選用粗絲來完成型孔的電火花銑削,以去除絕大部分余量,這樣既快又可節(jié)省昂貴的細(xì)絲。作為一級(jí)方程式賽車 (F1)零部件加工所用電加工機(jī)床的指定合作伙伴,瑞士夏米爾的形象經(jīng)常 與F1 賽車相伴一起 ! 。 這種雙絲系統(tǒng)結(jié)構(gòu)非常簡潔,與原來走絲系統(tǒng)比,走絲路程并沒有變化,只是 外加了一個(gè)粗電極絲庫,并在每根傳動(dòng)軸上裝了兩個(gè)導(dǎo)絲輪,采用拉鍵和剎車的辦法來選擇需要哪一套走絲系統(tǒng)工作。由于 PILOTEXPERT 專家系統(tǒng)能很好地控制集中放電的能量,從而在防止斷絲的同時(shí)也解決了局部過熱的問題。 消除表面微裂紋 當(dāng)前公認(rèn)的高附加值的沖模是長壽命的硬質(zhì)合金精密沖模。 ● 電極可在型面方向伺服和抬刀,使得對(duì)型腔每個(gè)局部的精修與常規(guī)的主軸直上直下的放電相比沒有什么區(qū)別,加工穩(wěn)定可靠。例如,當(dāng)電極截面尺寸為 2mm 20mm、被加工的型腔深度為 100mm 時(shí),采用石墨電極加工僅需 ,采用紫銅電極加工僅需 。通常的做法是采用沖抽油沖刷排屑,以保證加工處于穩(wěn)定狀態(tài),但不均勻的流場(chǎng)會(huì)造成不均勻的切屑堆積,對(duì)加工后的平面度影響很大,而且強(qiáng)烈的沖刷還會(huì)引起邊角異常損耗。這樣就會(huì)在此局部產(chǎn)生一連串脈沖放電現(xiàn)象,直到此處變得相當(dāng)凹陷。 As the designated partners by F1 , It provide the machine of EDM used in parts machining。 Similarly, we can also use the thin wire electrode to processing。 As PILOTEXPERT expert system can effectively control the discharge of concentrated energy, In order to prevent broken wires at the same time solve the problem of local overheating。 Under normal circumstances, surface cracks will not only produce electricity processing, even the g
