I-CNC Machining: Lapho Ithiyori Ihlangana Nomzila Wamathuluzi
Ukucupha lezi zingxubevange yilapho irabha ihlangana khona nomgwaqo. Akuyona eyabantu ababuthakathaka. Awukwazi ukuvele uphonse isigayo esijwayelekile kuso. Sikhuluma ngamathuluzi e-carbide aqinile, amajiyometri athile ama-alloys asezingeni eliphezulu, futhi kwesinye isikhathi ngisho ne-CBN (cubic boron nitride) yokuqeda. Ukuqina kokusetha kubaluleke kakhulu; noma yikuphi ukuxoxa kuzolimaza ubuqotho obungaphezulu obubalulekile ekuphikiseni ukukhathala.
Imininingwane evame ukunganakwa yisimo sempahla ngaphambi kokuthi ishaye umshini we-CNC. Ngoba Co 21 abalingiswa, ingabe basesimweni esifana nesakho, baphathwa isixazululo, noma sebekhulile ngokuphelele? Ubulukhuni kanye ne-ductility ihluke kakhulu. Sake sakha inqwaba ye-as-cast Co 21 izindlu. I-geometry yayiyinkimbinkimbi, inezindonga ezincane. Esimeni se-as-cast, okokusebenza bekunengcindezi eyinsalela futhi bekuthambile kancane. Ukwenza imishini kuhambe kahle, kodwa ngemva kokwenza ukuqina kweminyaka edingekayo yangemva komshini, ezinye zezingxenye ezacile zibonise ukuhlanekezela okuncane—izinkulungwane ezimbalwa zamayintshi, kodwa okwanele ukuba zingabekezeleli indawo yokukhwelana. Safunda. Manje, ezingxenyeni ezinobukhulu obubucayi, sivamise ukwenza umsebenzi womshini onzima esimweni esithambile, bese sifaka ukwelashwa kokushisa kokugcina, okulandelwa ukudlula kokuqeda ukukhanya ukuze kuqiniswe ijometri. Yengeza isinyathelo, kodwa iqinisekisa umphumela.
Isu lokupholisa ngesinye isihloko esiphelele. Ngalawa ma-alloys, ukukhiqizwa kokushisa onqenqemeni lokusika kunamandla. Udinga ukuyiphatha, kodwa futhi ucabangele i-chemistry. Amanye ama-alloys e-cobalt asebenza kahle kakhulu angazwela kwezinye izithasiselo zesulfure noma ze-chlorine ezipholiseni, ezingase zidale ukuqhekeka kokugqwala kwengcindezi kamuva. Sisebenzisa i-pH engathathi hlangothi, izipholisi ze-semi-synthetic futhi sizigcine ngokucophelela. Kuyimininingwane encane esikimini esikhulu, kepha kuleli bhizinisi, imininingwane emincane iyisikimu esihle.
Inzuzo Yokuhlanganisa: Ukusuka I-Shell Mold kuya Engxenyeni Eqediwe
Lokhu kungibuyisela emnyombweni wokuthi umsebenzi ohlanganiswe mpo njenge-QSY uphatha kanjani into efana nayo Co 21. Inqubo yokulingisa isikhunta segobolondo esiyisebenzisayo inhle ekuzuzeni ijiyometri eyinkimbinkimbi, eseduze nenethi lezi zingxenye zenani eliphezulu ezivame ukudingwa. Uma usakaza ingxenye ye-turbine eyinkimbinkimbi noma i-prototype yokufakelwa kwezokwelapha Co 21, ufuna isitokwe somshini esilandelayo esincane—mhlawumbe u-0.5mm ngobuso.
