Uma uzwa 'i-advance precision machining', izingqondo eziningi zigxumela ziqonde ekubekezeleni kwezinga le-micron kanye nokunikezwayo okucwebezelayo kwe-CAD. Leyo yingxenye yakho, impela, kodwa yingxenye elula. Indaba yangempela iqala lapho unenqwaba yokulingisa kwe-Inconel 718 etafuleni, ukuphrinta kubiza ±0.02mm, futhi ufaka i-thermal drift, ukugqokwa kwamathuluzi kusukela ekugcineni, nokuthi ukugxilisa okupholile kuyabonakala. Lelo gebe phakathi kokucaciswa kwetiyori kanye nengxenye ebonakalayo—yilapho le geyimu idlalwa khona ngempela. Akukhona nje ngokuba nomshini wama-eksisi amahlanu; kumayelana nokwazi ukuthi lowo mshini uzokwenzani ngempela ngo-3 PM ngoLwesihlanu olunomswakama.
Isisekelo: Iqala ngokulingisa
Awukwazi ukwenza ukunemba komshini ube ukusakaza okubi. Ngibone amaphrojekthi amaningi echitheka ngenxa yokuthi othile wayecabanga ukuthi isiteji se-CNC singalungisa ngokumangalisayo amashifu ayisisekelo noma i-subsurface porosity evela kumsunguli. I-machining iyincazelo yokugcina, ebucayi, kodwa ubuqotho bengxenye buzalwa ngaphambili kakhulu. Kungakho ukuhlanganiswa kokusakaza nokwenza imishini ngaphansi kophahla olulodwa, njengase-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kungekona nje ukuhleleka kalula—kuyisu eliyisisekelo lokulawula ikhwalithi. Uma ithimba elifanayo elisebenzisa ingxenye liphinde liqondise isikhunta segobolondo noma inqubo yokutshala imali, ususa lonke ungqimba lokukhombana ngomunwe nokungaqiniseki.
Thatha umsebenzi wabo ngama-alloys asekelwe ku-nickel. Ukwenza lokhu akuyona nje indaba yokukhetha ibanga elifanele lokufaka. Udinga ukuqonda ukugeleza okusanhlamvu kusukela kunqubo yokuphonsa, ukuthi isimo sokudambisa ingcindezi sizosebenzisana kanjani namandla akho okubamba, nokuthi lezo zindawo ezinenkani zingase zicashe kuphi. Uma ukulingisa kungakhiqizwa ngokulandelayo kusengaphambili ukunemba machining engqondweni, ulwa impi ekhuphukayo kusukela koxhumana naye wethuluzi lokuqala.
Ngikhumbula ingxenye ye-hydraulic manifold, ucezu lwensimbi oluyinkimbinkimbi. Umdwebo wawunolaka. I-Foundry ekhiqize izikhala zokuqala ayizange ihlanganiswe nesitolo semishini. Umphumela? Ukujiya kodonga okungahambisani ngemuva kobuso obubalulekile bokuvala, okuholela kuphupho elibi ngesikhathi sokuqeda. Ezinye izingxenye zagezwa, ezinye zavuza. Ukube inqubo yokusakaza ibithuthukisiwe ngezixhumanisi zokugcina zemishini njengokufakwayo okuyisiqondiso—into umphakeli odidiyelwe njenge QSY yenza njengenjwayelo-ukuthi ukumosha nokusebenza kabusha bekuyogwenywa emthonjeni.
Indlela Yamathuluzi iyingxoxo, Hhayi Umyalo
Isoftware ye-CAM ikunikeza indlela yamathuluzi. Umshini uzama ukuwulandela. Umbono ongenangqondo uthi lesi isiphetho sendaba. Umbono onolwazi ukuthi yilapho ingxoxo iqala khona. Okweqiniso kusengaphambili ukunemba machining, ikakhulukazi kumajiyometri ayinkimbinkimbi asuka ekulingisweni komumo we-net-net, indlela ehleliwe imane iwuhlaka lokuqala.
Kufanele ulalele ukusikwa. Umsindo, umbala we-chip kanye nefomu, ukuhluka okuncane kokufundwa kwamamitha okulayisha—konke kuyimpendulo. Emzimbeni wevalvu yensimbi engagqwali, singase sihlele isivinini sangaphezulu esingaguquki kanye nokuphakelayo. Kodwa uma ungalungiseleli okwamanje isigayo sokugcina sihlanganisa i-cross-bore yangaphakathi ngokumelene nodonga lwangaphandle oluhlanzekile, uzothola ingxoxo noma ukuchezuka. Ingxenye 'eyaphambili' yilesi sendlalelo sokulawula esiguquguqukayo, esicishe sibe enembile esihlezi phezu kwekhodi ye-G. Ingcweti yemishini noma umhleli azi ukuthi kule nqwaba engu-17-4 PH engenabala kusuka ekuncibilikeni okuthile, badinga ukulahla okuphakelayo ngo-5% emaphaketheni.
Yilapho iminyaka engama-30 yengemuva le-QSY ebalula khona iba yinto ebonakalayo. Akuyona nje iminyaka engu-30 yemishini egijima; iminyaka engu-30 yokwakha umtapo wolwazi wengqondo wokuthi izinto ezivela kuma-alloys asekelwe ku-cobalt kuya ekubunjweni kwensimbi ziziphatha kanjani ngaphansi kwethuluzi. Lowo mtapo wezincwadi wazisa lezo zinguquko ezincane ezihlukanisa ingxenye enhle nephelele.
I-Metrology: Ukulinganisa Ukwazi (Mhlawumbe)
Nasi isicupho esivamile: ukuthembela ngokweqile embikweni we-CMM. Uthola ishidi lokuhlola le-athikili yokuqala elinawo wonke amanani aluhlaza futhi ucabange ukuthi uyigolide. Kodwa yayiyini izinga lokushisa lengxenye lapho ikalwa? Ingabe izici zedatha zahlanzwa kuzo zonke izinsalela zokupholisa kanye nama-micro-burrs? Ingabe i-clamping ngesikhathi sokulinganisa bekulingisa kahle ukugoqa ngesikhathi somshini? Uma kungenjalo, lowo mbiko omuhle uwumsebenzi wenganekwane.
Emsebenzini wokunemba, ukulinganisa kuwubuciko ngokwako. Sivame ukusebenzisa inhlanganisela yezindlela. I-CMM yokubekezelelana kwejiyomethri kukonke, yebo. Kepha ezindaweni ezibucayi zophawu, mhlawumbe i-surface profilometer. Ukuze uthole ama-diameter angenalutho ezicini ezijulile, ezincane, igeji yomoya elinganisiwe noma isethi ye-pin gage ethize. Umgomo uwukuhlobanisa—ukuqinisekisa ukuthi zonke izindaba zakho zokulinganisa ziyavumelana. Ngike ngaba nezimo lapho i-CMM ithi isibhobo siyabekezelelana, kodwa i-master plug gage ngeke ilingane. Umlandu? I-taper engaqondakali noma i-lobing egejiwe yisampula lephoyinti le-CMM. Umqondo 'wokuthuthukile' uwukungabaza okunempilo mayelana nedatha yakho.
Enkampanini ephethe yonke into kusukela ezisekelweni ezinkulu zensimbi kuya ezingxenyeni ze-alloy turbine ezithambile, le filosofi ye-metrology kufanele ikhule futhi iqaphele izinto ezibonakalayo. Ukulinganisa ubakaki wensimbi owenziwe ngomshini akufani nokulinganisa ingxenye yengxubevange ye-cobalt enezindonga ezincane engase igoqeke ngaphansi kwesisindo sayo kusiteji se-CMM.
I-Special Alloys Arena: Lapho Ithiyori Ihlangana Nethuluzi
Noma ubani angabheka izivinini ezinconyiwe kanye nokuphakelayo kwe-Inconel encwadini yesandla. Ukuwalandela ukukhiqiza ingxenye esebenzayo kungenye indaba. I-Advance precision machining yama-alloys akhethekile afana nalawo asekelwe ku-nickel noma asekelwe ku-cobalt wucwaningo lolaka olulawulwayo. Udinga ukushisa okwanele endaweni yokugunda ukuze ugcine ipulasitiki yezinto ezibonakalayo, kodwa hhayi kakhulu kangangokuthi usebenza-qinisa indawo ibe isendlalelo esingangeneki esizobhubhisa ithuluzi lokudlula elilandelayo.
Ukukhetha ithuluzi kuba bucayi kakhulu. Hhayi nje noma iyiphi i-ceramic noma i-carbide ezokwenza. I-geometry ye-insert, i-coating, idizayini ye-chipbreaker-konke kudinga ukulungiswa. Ukupholisa akukona nje ukupholisa; okokugcoba nokukhishwa kwe-chip ezingcindezini ezingadlula i-1000 psi. Ukwehluleka kunoma isiphi isixhumanisi salolu chungechunge kusho ingxenye elahliwe, futhi lezi zinsiza azishibhile. Imajini yephutha cishe inguziro.
Leli ikhono eliwumongo lomnikezeli ofana naye QSY. Ukukhuluma kwabo ngalezi zinto akuwona amazwi akhulunywayo; kuwuphawu lokuthi batshale imali kumshini othize wokuqina wamathuluzi, amasistimu wokupholisa umfutho ophezulu, futhi okubaluleke kakhulu, ulwazi lomsebenzisi ukuze aqhube le gauntlet ngempumelelo. Akuyona ibhizinisi eseceleni; yikhono elizinikele.
Ukuhlanganiswa: Ukusebenza Okungabonakali
Ekugcineni, ake sikhulume ngokugeleza. Isitha esikhulu sokunemba ukungqubuzana, futhi ukungahambisani kuvame ukuvela ekubambeni ngesandla. Uma ukulingisa kwenziwa efekthri eyodwa, kuthunyelwa kwenye ukuze kwenziwe imishini enzima, bese kweyesithathu ukuze kuqedwe, wethula okuguquguqukayo kuzo zonke izigaba. Izimo ezihlukene zokushisa, amafilosofi ahlukene okubamba, amazinga ahlukene wamathuluzi.
Umsebenzi odidiyelwe ophatha isikhunta segobolondo/ukusakaza kokutshalwa kwezimali kanye kusengaphambili ukunemba machining ekuhambeni okudidiyelwe kuqeda lezi ziguquguqukayo. Ingxenye ayilokothi iphole ibe yisimo esingaziwa phakathi kwemisebenzi emikhulu. Ithimba elifanayo lobuchwepheshe lingahlela isango lokulingisa kanye nezindawo zokukhuphuka ngokusekelwe lapho izici zokugcina ezibalulekile zizokwenziwa ngomshini, kuncishiswe isitokwe esiningi kanye nokuhlanekezela. Ivumela umklamo wenqubo ophelele ngempela.
Lena inzuzo ecashile ngemuva kwemodeli egxile mpo. Kuncane mayelana nemishini ngayinye nokunye okuningi mayelana nentambo engenamthungo yokulawula ukusuka ensimbi encibilikisiwe ukuya engxenyeni ephelile, ehloliwe. Ukunemba akwenziwa ngomshini nje; kubhakwe kulo lonke uhlelo kusukela osukwini lokuqala. Uma uthola izingxenye eziyinkimbinkimbi, ezisebenza kahle kakhulu, lobo bunikazi bokugcina benqubo akubona ukunethezeka—imvamisa kuwukuphela kwendlela yokuqinisekisa umphumela wezimfuno zokuphrinta.
