Dr\u00f4tov\u00e9 EDM (dr\u00f4tov\u00e9 elektroeroz\u00edvne obr\u00e1banie)<\/h2>\n

Dr\u00f4tov\u00e9 EDM, naz\u00fdvan\u00e9 aj dr\u00f4tov\u00e9 elektroeroz\u00edvne obr\u00e1banie, pou\u017e\u00edva tenk\u00fd dr\u00f4t na presn\u00e9 vyrez\u00e1vanie tvarov do kovu.<\/p>\n

Ako funguje dr\u00f4tov\u00e9 EDM<\/h3>\n

Pri dr\u00f4tovom EDM sl\u00fa\u017ei tenk\u00fd dr\u00f4t ako elektr\u00f3da. Zvy\u010dajne je vyroben\u00fd z mosadze alebo medi a je napnut\u00fd medzi dvoma cievkami. Dr\u00f4t sa kovov\u00e9ho obrobku nikdy nedot\u00fdka.<\/p>\n

Medzi dr\u00f4tom a kovom pr\u00fadi elektrick\u00fd pr\u00fad a vytv\u00e1ra drobn\u00e9 iskry.<\/p>\n

Iskry roztavia a odparia mal\u00e9 \u010dasti kovu. Voda alebo in\u00e1 kvapalina odplavuje roztaven\u00fd kov a chlad\u00ed pracovn\u00fa oblas\u0165. Dr\u00f4t sa plynulo pohybuje po dr\u00e1he riadenej po\u010d\u00edta\u010dom. Dr\u00f4tov\u00e9 EDM dok\u00e1\u017ee vytv\u00e1ra\u0165 ostr\u00e9 rohy, mal\u00e9 otvory a \u00fazke \u0161trbiny.<\/p>\n

Proces je najvhodnej\u0161\u00ed pre tvrd\u00e9 kovy, ktor\u00e9 sa be\u017ene \u0165a\u017eko re\u017e\u00fa. Ke\u010f\u017ee nedoch\u00e1dza k priamemu kontaktu, nevznik\u00e1 mechanick\u00e9 nap\u00e4tie ani praskliny.<\/p>\n

Pou\u017eitie dr\u00f4tov\u00e9ho EDM<\/h3>\n

Dr\u00f4tov\u00e9 EDM je ob\u013e\u00faben\u00e9 v odvetviach, ktor\u00e9 potrebuj\u00fa vysoko presn\u00e9 s\u00fa\u010diastky. Pou\u017e\u00edva sa napr\u00edklad na v\u00fdrobu lisovac\u00edch, rezac\u00edch alebo tvarovac\u00edch n\u00e1strojov a foriem na kov \u010di plast.

Dr\u00f4t sa kovu priamo nedot\u00fdka, \u010d\u00edm sa zni\u017euje riziko po\u0161kodenia a opotrebovania n\u00e1stroja. Dr\u00f4tov\u00e9 EDM vytv\u00e1ra aj ve\u013emi zlo\u017eit\u00e9 tvary a jemn\u00e9 prvky, ktor\u00e9 sa \u0165a\u017eko vyr\u00e1baj\u00fa p\u00edlou alebo vrt\u00e1kom.<\/p>\n

Je vhodn\u00e9 aj pre tenk\u00e9 alebo krehk\u00e9 s\u00fa\u010diastky, preto\u017ee na materi\u00e1l nep\u00f4sob\u00ed mechanick\u00fdm nam\u00e1han\u00edm. Zlo\u017eit\u00e9 vzory mo\u017eno vyreza\u0165 do mal\u00fdch \u010di krehk\u00fdch dielov bez ohnutia alebo deform\u00e1cie. Preto je vhodn\u00e9 na detailn\u00e9 a presn\u00e9 s\u00fa\u010diastky.<\/p>\n

Elektroeroz\u00edvne obr\u00e1banie h\u013abiacou elektr\u00f3dou<\/h2>\n

H\u013abiace EDM, zn\u00e1me aj ako ramov\u00e9, dutinov\u00e9 alebo ponorn\u00e9 EDM, vyu\u017e\u00edva er\u00f3ziu iskrami na vytv\u00e1ranie presn\u00fdch tvarov v kove. Pou\u017e\u00edva sa na zlo\u017eit\u00e9 dutiny a detaily, ktor\u00e9 sa in\u00fdmi obr\u00e1bac\u00edmi met\u00f3dami vyr\u00e1baj\u00fa \u0165a\u017eko.<\/p>\n

Rozdiel medzi h\u013abiacim a dr\u00f4tov\u00fdm EDM<\/h3>\n

Pri h\u013abiacom EDM sa tvarovan\u00e1 elektr\u00f3da, \u010dasto z grafitu alebo medi, \u201epon\u00e1ra\u201c do obrobku. Takto mo\u017eno vytv\u00e1ra\u0165 detailn\u00e9 3D tvary vo vn\u00fatri s\u00fa\u010diastky. Elektrick\u00e9 iskry medzi elektr\u00f3dou a kovom postupne eroduj\u00fa materi\u00e1l tak, aby zodpovedal tvaru elektr\u00f3dy.<\/p>\n

Pri dr\u00f4tovom EDM tenk\u00fd dr\u00f4t re\u017ee s\u00fa\u010diastku po naprogramovanej dr\u00e1he. Hod\u00ed sa na prerez\u00e1vanie materi\u00e1lu a tvary s rovn\u00fdmi hranami. H\u013abiace EDM je naopak vhodnej\u0161ie na dutiny, formy a tvary n\u00e1strojov. Nepou\u017e\u00edva sa s\u00favisl\u00fd dr\u00f4t, ale elektr\u00f3da vyroben\u00e1 na mieru.<\/p>\n

Materi\u00e1ly vhodn\u00e9 na h\u013abiace EDM<\/h3>\n

H\u013abiace EDM mo\u017eno pou\u017ei\u0165 na mnoh\u00e9 vodiv\u00e9 materi\u00e1ly. Medzi najbe\u017enej\u0161ie patria:<\/p>\n

    \n
  • N\u00e1strojov\u00e9 ocele<\/strong><\/li>\n
  • Kalen\u00e9 ocele<\/strong><\/li>\n

    EDM na v\u0155tanie otvorov<\/h2>\n

    EDM na v\u0155tanie otvorov je met\u00f3da na vytv\u00e1ranie presn\u00fdch hlbok\u00fdch otvorov vo vodiv\u00fdch kovoch. Je obzvl\u00e1\u0161\u0165 u\u017eito\u010dn\u00e1 pri otvoroch mal\u00e9ho priemeru, ktor\u00e9 nemo\u017eno vyv\u0155ta\u0165 be\u017en\u00fdm vrt\u00e1kom.<\/p>\n

    Proces EDM v\u0155tania otvorov<\/h3>\n

    Pri EDM v\u0155tan\u00ed sa elektrick\u00fdmi v\u00fdbojmi eroduje materi\u00e1l obrobku. R\u00farkov\u00e1 elektr\u00f3da sa umiestni bl\u00edzko kovov\u00e9ho povrchu. Medzi elektr\u00f3dou a kovom vznik\u00e1 s\u00e9ria riaden\u00fdch iskier, ktor\u00e9 roztavia a odparia mal\u00e9 mno\u017estvo materi\u00e1lu.<\/p>\n

    Stroj odplavuje ne\u010distoty dielektrickou kvapalinou, \u010dasto deionizovanou vodou. Otvor tak zost\u00e1va \u010dist\u00fd a predch\u00e1dza sa skratu. Proces je ve\u013emi presn\u00fd a nevy\u017eaduje priamy kontakt, preto mo\u017eno v\u0155ta\u0165 aj tvrd\u00e9 alebo krehk\u00e9 kovy bez ich popraskania.<\/p>\n

    Touto met\u00f3dou mo\u017eno v\u0155ta\u0165 otvory s priemerom u\u017e od 0.15 mm (0.006 inches). Vhodn\u00e1 je aj na hlbok\u00e9 otvory, dokonca do h\u013abky nieko\u013ek\u00fdch palcov, s vysok\u00fdm pomerom h\u013abky k priemeru. Otvor teda m\u00f4\u017ee by\u0165 mnohon\u00e1sobne hlb\u0161\u00ed, ne\u017e je jeho \u0161\u00edrka.<\/p>\n

    EDM v\u0155tanie vytv\u00e1ra rovnomern\u00e9 otvory bez otrepov. Nie je potrebn\u00e9 sekund\u00e1rne dokon\u010dovanie, \u010do \u0161etr\u00ed \u010das aj pr\u00e1cu. Je preto ide\u00e1lne pre n\u00e1ro\u010dn\u00e9, krehk\u00e9 alebo na teplo citliv\u00e9 materi\u00e1ly.<\/p>\n

    Mo\u017eno v\u0155ta\u0165 jedine\u010dn\u00e9 tvary a vzory, ktor\u00e9 by sa in\u00fdmi met\u00f3dami vyr\u00e1bali \u0165a\u017eko, napr\u00edklad otvory v lopatk\u00e1ch turb\u00edn, vstrekova\u010doch paliva alebo zdravotn\u00edckych implant\u00e1toch.<\/p>\n

    Proces je r\u00fdchly a presn\u00fd<\/strong>, a to aj v tvrd\u00fdch kovoch, ako tit\u00e1n alebo karbid. Ke\u010f\u017ee sa n\u00e1stroj povrchu fyzicky nedot\u00fdka, menej sa opotreb\u00fava a mechanick\u00e1 sila takmer nehroz\u00ed po\u0161koden\u00edm s\u00fa\u010diastky.

          Ako funguje h\u013abiace EDM?<\/h3>\n

          Pri h\u013abiacom EDM sa pou\u017e\u00edva elektr\u00f3da vytvarovan\u00e1 pod\u013ea po\u017eadovanej s\u00fa\u010diastky. Elektr\u00f3da sa pos\u00fava do obrobku a elektrick\u00e9 iskry tvaruj\u00fa kov. Proces je vhodn\u00fd na v\u00fdrobu detailn\u00fdch foriem a lisovac\u00edch n\u00e1strojov.<\/p>\n

          \u010co treba zv\u00e1\u017ei\u0165 pri v\u00fdbere medzi dr\u00f4tov\u00fdm EDM a in\u00fdmi met\u00f3dami EDM?<\/h3>\n

Dr\u00f4tov\u00e9 EDM je najvhodnej\u0161ie na ve\u013emi presn\u00e9 rezy alebo zlo\u017eit\u00e9 tvary v tvrd\u00fdch kovoch. H\u013abiace EDM je lep\u0161ie na hlbok\u00e9 dutiny alebo tam, kde potrebujete elektr\u00f3du vyroben\u00fa na mieru.<\/p>\n

          Ak\u00fd je z\u00e1kladn\u00fd princ\u00edp fungovania EDM strojov?<\/h3>\n

          EDM stroje eroduj\u00fa kov z obrobku pomocou elektrick\u00fdch iskier. Iskra presko\u010d\u00ed medzi elektr\u00f3dou a kovom a roztav\u00ed drobn\u00e9 \u010dasti materi\u00e1lu. Na riadenie procesu a odplavovanie ne\u010dist\u00f4t sa pou\u017e\u00edva \u0161peci\u00e1lna kvapalina naz\u00fdvan\u00e1 dielektrick\u00e1 kvapalina.<\/p>\n
