Izingxenye ezincane zokunemba zingashintshwa ngokunemba okuphezulu emishinini emikhulu ye-EDM, kodwa hhayi ngokuphambene nalokho. Lokho osekuvele kungenzeka ekubholeni kwe-EDM, i-bes Funkenerosion evela ku-Fluorn-Winzeln nayo ifuna ukukufeza ekusikeni ucingo.
Umkhiqizi waseJalimane uBes Funkenerosion kwadingeka enqabe ama-oda esikhathini esidlule ngoba imishini yabo ye-wire EDM yayingenawo la mabanga okuhamba. “Sinamakhasimende asebenzayo angaphezu kuka-500, futhi uma ungakwazi ukuthatha ama-oda ngoba nje ubukhulu bomshini abukuvumeli, ngokwemvelo kunzima,” kuchaza umqondisi ophethe uMarkus Langenbacher.
Kodwa-ke, indawo yokupaka imishini enemishini ye-Sodick EDM isivele ihlaba umxhwele impela, eyodwa i-ALC400G, eyodwa i-SLC400G, eyodwa i-AG400L kanye nenye i-AQ750LH. Izinsizakalo ze-Wire EDM ekukhiqizweni kwenkontileka azikaze ziphazamise noma yiziphi izifiso zamakhasimende, ngaphandle kokuthi ngaphakathi kobubanzi be-XXL kufanele benqabe ama-oda ngezikhathi ezithile.
“Sisebenzise i-wire EDM kusukela ekuqaleni, futhi ngokushesha senezela ne-die sinking,” kusho uJörg Romen, ophethe umnyango wokugqwala kwezintambo. Lapho ama-oda enkontileka eqala ukwanda, ama-EDM amasha kumele athengwe. Ukukhetha kwawela kuSodick. “USodick usinikeze isipho esikhangayo esihlanganisa konke semishini emithathu, esiphinde sasenza saqiniseka ngekhwalithi nokunemba kwayo,” kusho uJörg Roming. Emishinini emithathu yokuqala, munye kuphela osasebenza; emibili isishintshiwe ngokuhamba kwesikhathi. “Siphinde sasebenzisa i-aluminium eningi, eyabeka ingcindezi enkulu emshinini. Namuhla siyazi ukuthi uma besisika i-aluminium emshinini usuku lonke, ngezikhathi ezithile bekuzodingeka sithathe indwangu enomnyango ovulekile bese sichitha imizuzu emihlanu sisusa konke Konke kuhlanziwe, ngaphandle kwalokho kuzothinta impilo yomshini.”
Imishini ye-XXL: Ekuqaleni yathengwa njengomshini wokufaka esikhundleni, manje isiyisithasiselo esifanele sokuqhubeka nokusika ngocingo ngaphandle kokuphazamiseka izingxenye ezinkulu enkambisweni yokubhoboza. (Umthombo: Ralf M. Haaßengier)
Njengomkhiqizi wenkontileka, i-bes Funkenerosion ilawula zonke izinqubo zokugqwala kusukela ku-EDM kuya ekubholeni nasekugqwaleni ngentambo. Amakhasimende angathenga futhi izesekeli nezinto ezisetshenziswayo ngqo enkampanini eseFluorn-Winzeln, njengokubhoboza nokufaka izintambo cishe kuzo zonke ubude nobubanzi. Amakhasimende abalulekile afaka abenzi bamathuluzi, abenzi bokubumba, izinkampani zobuchwepheshe bezokwelapha kanye nomkhakha wezindiza. "Izinto ezisetshenziswayo zingenye yezinsika zethu eziyinhloko futhi sinezinhlobo eziningi zamasheya esitokweni, ngakho-ke singahlala siqinisekisa izikhathi zokulethwa ezimfushane", kuqinisekisa uMarkus Langenbacher.
Izinto ze-electrode zihlolwa ukusebenza kahle emnyangweni wokuhlola ukuqinisekisa amakhasimende imiphumela emihle kakhulu ngesikhathi senqubo yokubhoboza i-EDM; le ndlela isho ukuthi ngisho nezidingo zamakhasimende ezikhethekile ngeke zibangele izinkinga enkampanini. Muva nje, ikhasimende li-ode ama-electrode angu-20,000 enkampanini ngemuva kokuhlolwa okuphumelelayo.
Lapho umsunguli wenkampani enquma ukuthatha umhlalaphansi ekuqaleni kuka-2021, kwadingeka umqondisi omusha ophethe. Kuleli hlobo, uMarkus Langenbacher wathatha izintambo zokuphatha i-bes Funkenerosion. Yiqiniso, lokhu kuyinhlanhla, njengoba kungenzeki njalo ukuthola umuntu ozongena esikhundleni senkampani yokukhiqiza. Akuvamile ukuthi abatshalizimali bangaphandle abangaqondi ukuguguleka noma indawo yamakhasimende bathathe izintambo. Ngemva kweminyaka embalwa, lezi zinkampani ngezinye izikhathi zithengiswa futhi “njengezingxenye ngazinye” bese ziwa. Kodwa-ke, ngaphansi kobuholi bukaMarkus Langenbacher, isisebenzi esinolwazi olukhulu sathatha izintambo. Njengoba ebe nenkampani iminyaka engu-21, akazi nje kuphela ibhizinisi kanye nezinqubo zokungena nokuphuma, kodwa futhi namakhasimende.
UMarkus Langenbacher uyazi kahle izinkinga zamakhasimende akhe: “Indlela iklayenti elisabela ngayo ukulinda iminyaka emibili kuya kwemithathu yokugcina ngaphambi kokufaka i-oda. Phela, abazi ukuthi kuzokwenzekani enkampanini lapho umsunguli ethatha umhlalaphansi. Bangaduduzeka lapho isidingo siqala futhi.
Lokhu kuqhakaza kuyathakazelisa ngoba isisebenzi sesimazi iminyaka engu-20, futhi manje lowo owayesebenza naye ngokuzumayo uba umphathi. UJörg Roming, obelokhu esebenza enkampanini iminyaka engu-18, ubona lokhu njengento enhle kakhulu: “Sixoxa ngokukhululekile ngoba sesimazi isikhathi eside. Lokho kuyinzuzo enkulu. Uma izinto zingahambi kahle, singaxoxa futhi sithole izixazululo ndawonye.”
Ekugcineni, abahlinzeki abanjengoSodick nabo bayazuza ekuthuthukisweni okuhle kwe-EDM. Ngemuva kokuthi i-ALC400G encane ilethwe enkampanini eseFluorn-Winzeln njengomshini wokufaka esikhundleni ekuqaleni kuka-2021, umlingani wayo omkhulu, i-ALC800GH, walandela ngasekupheleni kwehlobo. "Sithathe izinyathelo zokuqala zokwandisa ibhizinisi lethu lenkontileka ye-WEDM libe izingxenye ze-XXL ngomshini omkhulu we-WEDM. Lokhu kusenza sikwazi ukukhonza le makethe kuphela futhi asisadingeki ukwenqaba ama-oda," kuchaza umqondisi ophethe uMarkus Langenbacher. Ama-oda amasha azokhiqizwa ngokunikeza ulwazi kumakhasimende abanzi. "Ngepaki yethu yemishini, sizama futhi ukuqondisa ngqo amanye amakhasimende esinawo kakade ekubholeni kwe-EDM. Amakhasimende afuna ukushintshwa okuphelele kwezingxenye zawo ze-XXL kusuka emthonjeni owodwa, futhi manje singakunikeza lokho."

Eminyakeni edlule, i-bes Funkenerosion ibilokhu ithengisa ngendlela ehlukile emkhakheni we-wire EDM: ngendlela eseceleni engu-1460 x 600 x 1,020 mm, kungenzeka ukubhoboza izingxenye ezinesisindo esingafika kumathani ayi-6. Lezi zicelo nazo ziyinselele kakhulu. Ecaleni lomshini wakamuva, kwabhobozwa cishe imigodi engu-3,000 engxenyeni ethile emahoreni angu-145 okubhoboza. "Siphinde sabhekana nezingxenye ezinemigodi engu-14,000 - ipayipi elingamamitha angu-1.5 ubude elalingakwazi ukungena emishinini yethu," kukhumbula umqondisi ophethe we-bes. Sisebenzisa umshini wokushintsha i-electrode, ukucubungula kwenziwa imini nobusuku kwaze kwaba yilapho ipayipi libhobozwa ngokuphelele." Lawa ama-oda ethu ajwayelekile okukhiqiza inkontileka. Kodwa-ke, ubuchwepheshe bethu ekusikeni izintambo bubuyela emuva kakhulu. Yilapho saqala khona ngo-1983 njengenkampani yokukhiqiza."
Ukuqinisekisa ukuqala okuphelele kwama-oda okuqala ngemva kokufakwa kwemishini emisha yeSodick: uMarkus Langenbacher, uMqondisi Ophethe we-bes Funkenerosion, kanye no-BW Daniel Günzel, uMphathi Wezokuthengisa Wesifunda saseSodick Germany. (Umthombo: uRalf M. Haaßengier)
Ekuqaleni, i-Sodick VL600QH yathengwa njengomshini wokufaka esikhundleni. Kodwa njengoba i-ALC800GH yayisemakethe isikhathi esifushane, uMarkus Langenbacher noJörg Roming bayibhekile futhi ekugcineni banquma ukuyisekela. “Futhi, ngokuhlanganiswa nomshini wokubhoboza i-EDM esiwusebenzisayo, sesivele sinendlela eseceleni, futhi i-ALC800GH ilungele ukuvala indilinga ephakathi kokubhoboza kokuqala okungu-800 mm (kufika ku-1,000 mm kungenzeka) kanye ne-800 mm wire EDM EDM”, kusho uJörg Roming. Imishini emisha ye-EDM nayo iyaneliseka ngalokhu.
Kwakuyinguquko engenamthungo: umshini omdala wadilizwa, kwafika i-trailer eyisicaba enomshini we-XXL, futhi umshini omdala washintshwa ngomshini omusha, kanye nokonga okuhambisanayo ezindleleni zokuthumela. “Sobabili sisebenza ndawonye ngendlela engcono kakhulu,” kuqinisekisa uJörg Roming. Ngesikhathi umshini usehholo, wawuhlola nge-engeli ye-granite elinganiswe ngamamitha ama-2 nobude obungu-800 mm. Upakishwe emshinini kuzo zonke izinkomba futhi wahlolwa, ngisho nokwehluleka komshini omncane kakhulu kanye ne-engeli kubonakala. Njengoba wonke umshini we-Sodick uhlolwa ikhwalithi ngokulinganiswa kwejeneretha kanye nokulinganiswa kwejometri ngaphambi kokulethwa, akukho ukuphambuka e-engeli ye-granite.
Ngendlela, umsebenzi owaqala emshinini omdala manje uyaqhubeka ngaphandle kokuphazamiseka emshinini omusha: ukuphakama kokusika okungu-358 mm. "Saqaphela ngokushesha umehluko wekhwalithi. Enye inzuzo enkulu kithi ukuthi uhlelo lokulawula lwalucishe lufane, ngaphandle kokuthuthukiswa okumbalwa. Sathuthela ngokushesha ku-ALC800GH," kukhumbula uJörg Roming. Wakwazi nokudlulisela uhlelo emshinini omusha ngokushesha. "Sasidinga izinguquko ezincane kuphela kuprosesa yeposi, ngaphandle kwalokho ushintsho lwalungenankinga ngokuphelele."
Ngokuphathelene nemicu, i-EDM entsha imelela igxathu elikhulu phambili, futhi iqiniso lokuthi imiyalelo yokusebenza ihlanganiswe ngedijithali ohlelweni lokulawula liyinzuzo enkulu, esho. Akusekho ukuphenya nokusesha izincwadi zomsebenzisi kanye nezincwadi zokuhlela. Imidwebo, imiyalelo yokulungisa enemifanekiso, konke okubhalwe phansi. Izinombolo zezingxenye zingatholakala ngisho nangoko ngomsebenzi wokusesha. "Isinxephezelo sokushisa se-ALC800GH ngokwemvelo sinomthelela ekunembeni, ngakho ngisho nezingxenye ze-XXL zigqwala ngokunemba okuphezulu," kusho uJörg Roming ngokusobala.
Uhla lwethu lwemishini ye-EDM yocingo lungakhiqiza izingcezu ezifika ku-500. “Kithina njengochwepheshe be-EDM, lokhu kuyinani elikhulu,” kuchaza uJörg Romen. Inani elimaphakathi lokukhiqiza ngobuningi liphakathi kwezingcezu ezi-2 nezingama-20, kodwa ingxenye enkulu yakhiwa izingxenye ngazinye. Lokhu akunjalo ngokubhoboza, lapho uchungechunge lwamasonto onke lwezingcezu eziyi-1,000 lungavamile.” Lokhu ikakhulukazi kuvela kubenzi bamathuluzi anembile, isibonelo, sisebenzisa iziteshi zokupholisa ze-EDM njengezindawo zokusebenzela ezandisiwe,” kusho uMarkus Langenbacher.
Imibuzo yamakhasimende itholwa ngezindlela ezahlukene: ikhasimende elilodwa lithumela umbuzo nge-imeyili bese lilindela ikhotheshini, elinye lithumela ingxenye ngqo kwiphakheji enemidwebo, idatha ye-3D kanye nosuku lokulethwa, kanye nokuvakasha kwekhasimende lesithathu mathupha kithi. "Imisebenzi eminingi ihlanganisa nokulungiswa kwamathuluzi afana nama-die punches, okwakudingeka uma kungenzeka izolo," kumomotheka uMarkus Langenbacher. Unesizathu esihle sokuhleka ngoba umshini wakhe uguquguqukayo kangangokuthi ungaphatha ama-oda amaningi. Ikakhulukazi endabeni yokusika ku-inthanethi, imibuzo ivame ukuza nge-imeyili noma ngeposi ekhethekile enezingxenye, futhi izingxoxo zenziwa nekhasimende ngocingo. Amakhasimende ayisibonelo ahlinzeka ngamasethi edatha athembekile angu-100%. Eminyakeni engama-30 edlule, isisebenzi esisodwa besiphethe uhlelo lwe-CAM lwama-wire EDM kuphela, kodwa usethatha umhlalaphansi ekuqaleni kuka-2021. Ngakho inkampani yashintsha uhlelo lwe-wire EDM CAM ngomshini omusha we-Sodick. Njengoba i-CAM endala ingabuyekezwa futhi ingabonisa i-2D kuphela, izothathelwa indawo kancane kancane yi-CAM entsha. UJörg Roming manje usebenzisa i-CAM ngedatha ye-3D enikezwe yikhasimende futhi selivele linemingcele emihle kakhulu yokulingisa ukuthi yiziphi ubuso okufanele bufakwe kumishini nokuthi kanjani. "Inqubo yonke yokuqalisa, kufaka phakathi i-post-processor, ifana nomsebenzi wewashi le-CAM entsha," kusho uchwepheshe we-EDM ngentshiseko.
Nakuba inombolo yamahhala yocingo itholakala kuyo yonke imishini esanda kulethwa impilo yonke yomshini, uJörg Roming akakayisebenzisi kuze kube manje. “Inombolo yethu yocingo iqondile lapha,” emomotheka uDaniel Günzel. “Uma unakekela kahle imishini yakho, awusoze waphoqeleka ukushayela ucingo.”
Ngenxa yomklamo wesinki ongenazo izingxenye ezipendiwe, insimbi engagqwali kuphela kanye ne-ceramic yonke, kanye nomklamo wekhanda lamanzi elihlakaniphile, ukulungiswa nokuhlanza kungenziwa kalula ngemizuzu embalwa nje. Uma umshini usebenza usuku lonke futhi unomthwalo womsebenzi onzima, ngokuvamile kwanele ukusebenzisa isibhamu samanzi esifakiwe ukufutha isinki nokufutha ikhanda. Noma kunjalo, ithimba le-bes Funkenerosion lithatha ukulungiswa ngokungathi sína kakhulu. UMarkus Langenbacher uyachaza: “Muva nje sithuthukise uhlu lokuhlanza nokulungisa oluqondene nomshini ngamunye. UJörg Roming uyanezela: “Kubaluleke kakhulu kimi ukuthi imishini yami ye-EDM isebenze ngokwethembeka. Kungasiza kakhulu uma senza ukulungiswa okuphelele kanye ngonyaka, ngiyaqiniseka ukuthi uma ngifuna ukuqala ukusebenza emshinini ngingaqala ngokushesha ngaphandle kokuhlupheka.”
