Uma othile ethi izingxenye ezinemba okuphezulu, izingqondo eziningi zigxuma ziqonde ekubekezeleni okuqinile emdwebeni. ±0.005mm, Ra 0.4, lolo hlobo lwento. Yilokho okungaphezulu. Ingxoxo yangempela, leyo eyenzeka esitolo noma ngesikhathi socingo olumatasatasa lomphakeli, imayelana nayo yonke into eyenzekayo phakathi nalezo zinombolo. Kumayelana nokuzinza—hhayi nje okomshini, kodwa okokusebenza, inqubo, ngisho nemvelo phezu kokukhiqizwa kwezingcezu eziyizinkulungwane eziyishumi. Kulapho ukunemba kwetiyori kuhlangabezana khona neqiniso elimsulwa lokunwetshwa kokushisa, ukuguga kwamathuluzi, nokungahambisani okucashile kunqwaba yesitoko sebha yensimbi engagqwali. Amaklayenti amaningi, ikakhulukazi lawo asanda kuthola usizo, agxilisa ikhwelo lokubekezelela njengeyona metric yekhwalithi kuphela. Lona umbono oyiphutha wokuqala, futhi ovame ukubiza kakhulu.
Isisekelo: Iqala Ngokungenalutho
Awukwazi ukwenza ukunemba komshini ube yingxenye uma i-geometry yokuqala iyimfihlakalo. Yilapho ukusebenzisana phakathi kokulingisa nokwenza imishini kuba okungaxoxiswana. Ngibone amaphrojekthi ehluleka ngenxa yokuthi indawo eyenziwe ngomshini kahle yembule i-porosity ngaphansi, iphutha elizalwe esigabeni sokulingisa emasontweni adlule. Okweqiniso izingxenye zokunemba okuphezulu, ipulani lomshini limane liyisenzo sokugcina. Isenzo sokuqala siwukwenza umumo osondelene nenetha obikezelwe, ominyene, futhi ozinzile. Yingakho izinkampani ezilawula kokubili ukulingisa kanye nokwenza imishini ngaphansi kophahla olulodwa, njengokuthi I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ibe nomkhawulo ohlukile. Iminyaka yabo engamashumi amathathu kugobolondo nokutshala izimali kusho ukuthi bayaqonda ukuthi banganjiniyela kanjani okungenalutho—isisekelo—semishini elandelayo. Imayelana nokuklama inqubo yokusakaza ukuze kuncishiswe ingcindezi eyinsalela futhi inikeze ukushuba kodonga okungaguquki, ngakho-ke lapho ingxenye ifika ku-CNC, ayilwi namandla angaphakathi azama ukuyisonta njengoba kususwa okubalulekile.
Ukukhetha impahla lapha kubalulekile, futhi akukhona nje mayelana nezakhiwo zokugcina. Sikhuluma nge-machinability. I-alloy esekelwe ku-nickel esebenza kahle kakhulu ingase icaciswe ukumelana kwayo nokushisa, kodwa ukuthambekela kwayo kokwenza lukhuni kungase kuguqule ukusebenza okulula kokumba kube yiphupho elibi lamathuluzi aphukile kanye ne-geometry yembobo esengozini. Ukunemba akukhona nje endaweni yokugcina; kusemandleni okuzuza ngokubikezela nangokuphindaphindiwe lobo bukhulu kuyo yonke inqubo yokusika. Kwesinye isikhathi, ingxoxo kufanele ibuyele emuva kunjiniyela wokuklama: Singakubamba lokhu kubekezelelana, kodwa ingabe siyicabangele le enye ingxubevange enezakhiwo ezifanayo kodwa ukuzinza okungcono kwemishini? Ingase yonge u-30% ezindlekweni zamathuluzi futhi ithuthukise ukungaguquguquki kwenqwaba. Lokho kuwubizo olungokoqobo, lokwahlulela phansi.
Ngikhumbula ingxenye yevalvu ye-hydraulic, i-manifold encane ku-ductile iron. I-spec yayiqinile ku-bore concentricity. Amaqoqo okuqala avela kumthombo ojwayelekile wokusungula ayegcwele yonke indawo ngemva komshini. Inkinga? Ukuncipha okuncane ekulingiseni obekungabonakali phezulu kodwa kudale ubulukhuni obungalingani. Umsiki uzophambuka kancane, ngokungalindelekile.
