Umthi wokuthinta i-Wire EDM: Ubunzima bokulinganisa kakhulu kumsebenzi wokudla ngamathambo

Indlela Umfanekiso Wokukhuphisa Ngamakhabeli Ufunda Kanjani: Izinhlelo Zokugayazwa Kwe-Spark Nenkinga Eyisiseko

Ukuthini Ukukhuphisa Ngamakhabeli Futhi Ifunda Kanjani: Izinhlelo Zokugayazwa Kwe-Spark

Amashini e-Wire EDM achitha izintlangu ezinamandla ngokwakha izibhamu ze-electrical eziphazanyiswa phakathi kweyiwiri ye-brass enkimbini engu-0.02 kuze kube ngu-0.3 mm nendawo yentlango ofuna ukuyishintsha. Le zibhamu zihlaza kakhulu, zange zibe ngaphezulu kuka-12,000 degrees Fahrenheit, okusabalalisa imigxobo embancane yomthelela ngaphandle kokuthandakala ngempela. Okwenzela lokhu kufunyanwa kakhulu kukuba kuchitha kanjani, ngamathuba angu-micron kuphela. Ngoba yena lohlaka oluphelele, abakhethi abaningi bafisa Wire EDM xa basebenzisa izintlangu ezizinzile njenge-steel esiphilile noma lezi zilonda ezikhululekile ekugcineni ngendlela eyodwa.

Indima Yomshwama we-Dielectric Esikhundleni se-Wire Electrical Discharge Machining

Amahhala amancane ayenziwa izinkomba ezimbili eziphambene: ihlala njengesilonda ukuqeda imandla yensimbi kanye nokusula izinto ezithululwe kwi-0.02–0.1 mm kerf. Ngokuphindaphindwa kokuciphuna ukulahlekelwa kwezimali ku-1–20 µS/cm, leliqondo alibazekeli ubunzima kanye nobunzima bespark gap, okubaluleke kakhulu ekugcineni imigqa engaphansi kukaRa 0.2 µm.

Izinqubo Ezikhethekileyo Zomshini Wokugayaza Wire EDM: I-Electrode Yowhili, Isikhwama Se-Energy, Ne-CNC Control System

• I-Electrode Yowhili : Izinhlobo ezinezinhlaka ezincane zezinkunkuma zihlanza ukukhula kwekhiwili (kuya kude ku-15 mm²/min) futhi zilahle izahluko ngexesha lokugayazwa okumelene.
• Isikhwama Se-Energy Esitshelekayo : Isimiswa isikhathi sokutsheleka (50 ns–5 µs) nesivinini (1–32 A) ukuze sifakane ukukhula kanye nokulinganiso kwegcobo.
• Uhlelo lwe-CNC : Ishiyalala i-CAD/CAM ukuthatha izinyathelo ezigcwele ze-X/Y/U/V-axis, ukufinyelela ekugcineni kwemigwa yesilinganiso ye-±0.001°.

Ubuncinane Nokulinganisa Kwegcobo: Izinkinga Ezikhethekileyo Zomshini Wokugayaza Wire EDM

I-Tolerances Nezilinganiso Zomshini Wokugayaza Wire EDM: Ukufinyelela Ubuncinane Obuncane Kakhulu

Izimodi zasha zomshini wokugayaza wire EDM zifinyelela izilinganiso zomkhawulo njengezizini ±0.001 mm (0.00004 in) , ihlanganisa nezindlela zokugcina kodwa elimina ukungahlelekile kwezobuchwepheshe. Leliqiniso libuyisela kumthetho wokuphazanyiswa okungaphakathi, okuthinta izinto ngokuhlelekile njengoba kususelwa ku-0.1 µm ngalunye ulungelelo lokuphazanya.

Ubunzima bokugcina kwe-EDM yesihlwirekile: Kusuka kuthi ungafani njengesimilo kuya kubonakalayo

I-Wire EDM ibangela ubunzima besithuba kwiindawo eziphazanywayo phakathi kwe Ra 0.1–1.6 µm ikulingana nokuseta kwegunya kanye nophando lwesihlwirekile. Izinhilo zokugcina ezilandelayo zingasebenzisa iziganeko ezifanayo (Ra ≤0.4 µm), zibambezela ukuba kube yizilinganiso ezingu-80% ngaphambi kokuphatha ngokuphindwe (Ponemon 2023).

Akukho Mthwalo weNjine noma ukuqhamuka kwegunya Ngexesha Lokuchitha: Yenzelwe kwiZinto Ezinzulu

Umsebenzi wokuciphisa ngokwesintu uphazanya ngokupheleleyo ukuthi igunya libe liphambene nesiseko, likhulula ukusebenzisa izinto ezincinane kakhulu (<0.5mm) kumagunya athintekayo (60+ HRC) ngaphandle kokuthinteka. Leli qhaza linikela indlela ekufakelwa ngayo ematholeni azixhobo zokuchitha nezinqunyatha zomkhumbi apho ubunzima bokwenza kuyinto engeyiyo.

Izihlwirekile Ezincinane Kakhulu Nezinye Izingxenye Zokuchitha Ukulungiselela Kwizinto Ezinezici Ezipheleleyo

Igazi elincinane kangaka 0.02mm (0.0008") kuvumela i-machine yedliwa ngokusebenzisa imithamo engaphansi kwehlosi, okwaneleke kakhulu kwezinhlanga zezixwayiso zemithombo yesemikontho kanye nezinqubo zemoto yesikhathi. Izinyathelo ezisha kumithamo yezinkika ephuthelwe ngezinki kuthuthela ubunzima bokudlala ngokudlala ngokudlala kabusha ku-40% (IMTS 2024).

Ukuqina Kwinkulumo YokuHamba Ngokushesha Koma Ukucopheleka: Ingaba I-Wire EDM Ingayodlulisana Nezindlela Ezibalulekileyo Zokudlala?

Izimakhini zokugaya zinezintu ezihle kakhulu, zibaleka ngendlela ephindwa-phindwa kabili ukuya ku-5 ngesivinini sokugaya esibalulekile. Kodwa xa kusekelwe kumjikelo onjengamandla nezinhlelo, i-wire EDM isebenza kahle. Le ndlela ibe yindlela eyodwa kuphela ekudingekayo emva kokugaya kokuqala, ihlinza izinkinga ngokubamba izinto ezinzima ng during processing, futhi ithembisa imali kuzilimi okungaba kuzovaleka kakhulu uma kusebenziswa ngemithwalo engcono njengegciwane eliqineziwe. Isesiko sakugcwalisa esaphakade laselemnyakeni edlule sasifunene into ethintekileyo - i-wire EDM yabeka ixesha lemanufacturing ngamathuba angu-30% kungethemba yokugaya ngendlela esisisekelo xa kwenziwa amabhakethi akhethekile kakhulu asebenzisa titanium atholakala kwezimali zezinja, apho izidingo kumele kube phakathi kwemilimita engu-0.005 kabili.

Ukuthunyelana Kweteknoloji Kuma-Machines Amanje asebenzisa i-Wire EDM: i-CNC, Amakhanda Okusebenza Ngamaxesha Amahlanu, Nezimithwalo
