Metalworking Electroerosive

I roto i te hawhe tuatahi o te rautau rua tekau, kua whakaarohia kaipūtaiao te tukatuka whakarewa i te tiaki korakora. huaina ana tēnei tikanga te korakora horo. Ko te parau tumu whakahaere o te maimoatanga he kuware, me te ko e whai ake: hanga i roto i te uruhanga wai te maungārongo i waenganui i te electrodes e rua i raro i te ngaohiko (pitoake me te pitoiho). Ano, ko te tūranga o te pitoiho mahi he wahi o te mahi. I waenganui i te pitoake me te pitoiho te rere hiko. I roto i te pūngao pāhekoheko tukua te e taea whakamahana ake, ka tango matūriki maitai i te mata kawehiko. I roto i te mau parau te tahi atu, i reira he whakangaromanga o te paparanga whakarewa i raro i te pānga o hauruke hiko (whakarewa horo).

Na roto i te hoko i te ngaohiko ki te electrodes i te puka o ngātere poto, e kore e te pūngao ki te whakarewa pānga. Mā tenei e te tūemi i roto i te tukatuka kore e ngaro ratou āhuatanga ōkiko.

machining rere hiko. parau tumu o te mahi

I roto i te mahi, i te machining rere hiko ko e whai ake:

1. Ko te workpiece (pitoiho) kua whakatakotoria ki runga ki te tepu.
2. taputapu takanga hoki machining (waea wahi i hanga o parahi, graphite, parahi, konumohe) ki te mata mua-tukinotia. Ko te mata kia ahuahu ki tukurua te waka rererangi ki te whiwhi i runga i te workpiece.
3. taata tei mau Tool i roto i nga wahi neke o te mīhini. tono te reira ki te ngaohiko taputapu hihiko. Muri, te taputapu huarahi te workpiece.
4. Āhua "rärangi" o uruhanga i te puka o te mura i waenganui i te mata o te workpiece me te taputapu.
5. Ko te rohe mura o whakapā ki te mata workpiece e tupu patuki microparticles whakarewa. I hanga te rua iti. Ko rite ki te ngaohiko i waenganui i te workpiece me te taputapu Ko tōna hohonu.

Me kï reira e hūpeke te mura i waenganui i tino rite wahi i waenganui i te mata o te taputapu me te workpiece. Witi e milioni witi o iti korakora e nekehia atu i te mata whakarewa papaka ki te kia tukinotia. fakafuofua'i 'atu korakora tenei mata i roto i te puka ki te mata taputapu i roto i te puka Taupokia. Ka taea e te tukanga whakanui i te viivii ore, me te homogeneity o te tukatuka i te huri i te rerekētanga ngaohiko i runga i te taputapu me te āputa korakora. Ki te whakamahia hei taputapu mo te waea tapahia te workpiece ki tika teitei. I tua atu, ka taea ki te whakatutuki i nui ake matatini ara iahiko. A, no te kore e taea te whiwhi i ētahi atu tikanga o te tukatuka takiwa matatini.

He maha ngā painga machining rere hiko o konganuku:

• whakatutuki mata-kounga teitei machined (taurite, tika). Ko te kupu, ko te hiahia hoki mutunga atu riro;
• taea o te whiwhi rerekē kakano mata;
• obrabatyvaniya taea papa rawa pakeke (i runga 60 wae);
• mukunga riaka taipitopito pai e tika ana ki te kore o te ahotea aunoa;
• kākahu iti o te pitoake;
• faaineineraa o papa o rerekē āhua āhuahanga;
• kahore haruru i roto i te tukatuka.

horo korakora. Mā te whakamahi i te huarahi o

kitea tikanga rere hiko tona tono e whai ake:

• ngoto rua i roto i te workpieces o pakeke rerekē;
• te hanganga o nga rawa;
• tapahi wāhanga o pakeke rerekē;
• te tango i te tawhito ki nga wahi mea etaeta wahi;
• huri papa o tetahi pakeke;
• horoi o ngā wāhanga i muri i tunu alloys.

kitea hoki EDM tona whakamahi i roto i te hanga o te hanga mīhini. Ki te hanga te awhina o poporetanga te o nga wahi tawhito, wahi pakaru te tango i toromoka, te whakanui ake i ngā wāhanga paku tawhito.

I roto i te mutunga kia mohiotia ai e te kaha me te mauroa o te mihini, whakapakaritia tikanga mura hiko tei te nuinga i runga i tikanga tukatuka me te rauemi whakaū.
