Ngaba ufuna iinxalenye zentsimbi ezichanekileyo-ngokukhawuleza? Hayi "ukukhawuleza ukuphosa." Utyalo-mali olukhawulezayo lwefektri yokuphosa kuthetha ukuguqula izinto ezintsonkothileyo, ezinomgangatho ophezulu wentembeko njenge-AMS 5387 cobalt alloy pump housings ukusuka kumzobo ukuya ekuhanjisweni ngaphantsi kweentsuku ezingama-21. Ayikokukhawulezisa oko. Ihlaziya umgca wexesha.
Sizise ngaphezulu kwe-1,200 yeebhetshi ezijika ngokukhawuleza ukusukela ngo-2020-ubukhulu becala iivalvu zoxinzelelo, izindlu zesilinda sempompo yepiston, kunye ne-winch center shaft rollers yee-OEMs zehydraulic kuMntla Melika naseYurophu. Yintoni eyenza ukuba isebenze ayikhawulezi yodwa. Yindlela ukugalela ngokuqinileyo ngayo, ukutshixa, kunye nolawulo lwesinyithi ukuvala kunye.
Uninzi lwamaziko aluthatha utyalo-mali njengenkqubo ezimele. Bagalela iipateni zewax, amaqokobhe omlilo, icast, emva koko badluliselwe kwivenkile yoomatshini-ukuba ukhona. Ukulibaziseka istaki: ukucwangciswa konyango lobushushu, ukulungelelanisa umatshini wokulinganisa (CMM) ukusilela, izithuba zokulandela umkhondo. Sibone umxhasi omnye elinde iintsuku ezingama-47 ukuze aqinisekise ubukhulu bodonga kwiplagi yeoli kunye negesi. I-spec yabo ifuna ukunyamezela kwe-±0.05 mm kwi-120 mm yedayamitha ye-cobalt-nickel inxalenye. Ukulibaziseka kwakungasuki ekucotheni-kusuka ekuqhekekeni.
Isisombululo sethu siqala ngokudityaniswa ngokuthe nkqo-kungekhona njenge-buzzword, kodwa njengokuhamba komsebenzi wemihla ngemihla. Uyilo lwepateni yewax lwenzeka ecaleni kophononongo lwe-GD&T. Ixesha lokutshiswa kokungunda kweqokobhe lilungelelaniswa nokufumaneka kwesithando somlilo *kunye* noqikelelo lomthwalo we-spindle we-CNC. Imijikelezo yonyango lobushushu iqinisekisiwe kwangaphambili kwibakala ngalinye le-alloy-AMS 5387, T800, intsimbi ye-F22-ngoko akukho bhetshi ilinda iprofayili ye-thermal. Yonke i-ingot ye-cobalt alloy ingot engenayo ithwala iingxelo zokuvavanya ngokupheleleyo; yonke inxalenye egqityiweyo igcina ukulandeleka kwinqanaba eliphezulu ukuya kwinani lentlawulo yeziko.
Oku kuphelisa iindawo ezintathu zokungaphumeleli eziqhelekileyo kwiiprojekthi zokuphosa ngokukhawuleza:
- Idimensional drift phakathi kokusalwa kunye nokugqiba machining-isonjululwe ngokubamba ukunyamezelwa kwe-as-cast ukuya ku-± 0.3 mm ebusweni obubalulekileyo, emva koko usebenzisa ukuqinisekiswa kwe-CMM ngaphambi kokugaya okokugqibela
- Ukungahambelani kwe-Microstructure kwi-high-alloy castings-Iyalungiswa kusetyenziswa amaxabiso okupholisa alawulwayo ngaphakathi kumgca wethu we-ISO 9001-certified furnace kunye nexesha lokwenyani lokugawulwa kwe-thermocouple nge-ASTM E2862
- Isiphene esothusayo xa sihlolwa okokugqibela-ithintelwe ngokuskena okubonakalayo kwazo zonke iimolds zeqokobhe ngaphambi kokugalelwa kunye nemephu ye-porosity ezenzekelayo kwi-100% yeendawo ze-X-ray
Abanye banokuxoxa ukuba ukudibanisa okuqinileyo kuncama ukuguquguquka. Kodwa enyanisweni, okwahlukileyo koko kuyinyaniso. Xa umenzi wempompo waseYurophu efuna ukuphinda-phinda okuphindwe kathandathu kwe-nozzle ye-cobalt alloy nozzle-nganye ifuna i-geometry tweaks kunye nokuqinisekiswa okuhlaziyiweyo kwendlela yokuhamba-siye saqhuba iiprototypes ezipheleleyo ngeentsuku ezili-11 nganye. Kutheni? Ngenxa yokuba iinjineli zethu ziqinisekise ukwenzeka kokuphosa *ngexesha* lokuphononongwa kweCAD-kungekhona emva kokusikwa kwesixhobo. Akukho zoba ngokutsha. Akukho nkunkuma. Ukulungiswa okuphinda-phindayo ngaphakathi kwenkqubo enye.
Loo nkqubo ibandakanya izakhono ezine ezingundoqo ezisebenza phantsi kophahla olunye: ukuphoswa kotyalo-mali (kwijometri entsonkothileyo ukuya kuthi ga kwi-45 kg), ukuphoswa kwesanti (kwizindlu ezinkulu zesakhiwo), i-multi-axis CNC machining (i-5-axis ngaxeshanye kwi-impeller contours), kunye nokugqiba umphezulu osebenzayo-kuquka ukugquma kwe-HVOF kwiindawo zokunxiba kunye ne-passivation ye-stainless. Zonke zilinganiswe kwi-ASME B16.34, ISO 8502-3, kunye neeprothokholi zokuvavanya ukuvuza komthengi.
Yintoni abathengi abayifunayo ngokwenene-kwaye into esiyiphendulayo kuqala-ayisiyiyo "Ukukhawuleza kangakanani?" Ithi "Ngaba ungabamba i-0.002" kwesi sitya ngelixa ugcina ingqibelelo yokuhamba kweenkozo kwifillet? Okanye “Ngaba le T800 iplagi yealloy iya kusinda kwi-15,000 psi cyclic ilayishwa ngaphandle kokuqaliswa kwe-microcrack?” Okanye “Ngaba unabo ubungqina obubhaliweyo bokuba ibhetshi yakho ye-AMS 5387 ihlangabezana ne-AMS 2301 yokuqina kunye neemfuno zempembelelo?” Senza njalo. Ngalo lonke ixesha.
Ukusebenza kokuhanjiswa kwelizwe lokwenyani kuyaqinisekisa: I-94.7% yee-odolo zomthamo ophakathi (50-500 pcs) ngenqanawa phakathi kwe-±2 iintsuku zomhla wokuzibophelela. Iprototype ehamba phambili ye-avareji yeentsuku ze-14 ukusuka kumzobo ovunyiweyo ukuya kwinqaku lokuqala lokungeniswa-kunye nengxelo epheleleyo ye-dimensional, ii-certs eziphathekayo, kunye neerekhodi ze-NDT zibandakanyiwe. Akukho zongezo. Akukho ngaphandle.
Ukujonga phambili, i-bottleneck ayingomthamo-sisiqinisekiso. Amacandelo amaninzi afuna izatifikethi ze-EN 10204 3.2, ukuthotyelwa kwe-PED 2014/68/EU, okanye ulungelelwaniso lwe-API Q1. Ngoko ke sandisa uluhlu lwethu lweqela lesithathu lophicotho-zincwadi kunye nokuqinisekiswa kwenkqubo exutyiweyo yeehybrids ezenziwe ngoomatshini-ezifana nezigqeba ezidityanisiweyo zevalvu apho umsesane wesihlalo uphoswa utyalo-mali *endaweni*, emva koko igqitywe ukuze itshatise isikhondo.
Ukuba iprojekthi yakho elandelayo idinga iinxalenye zentsimbi ezichanekileyo-kungekhona nje ukuphosa, kungekhona nje iinxalenye zoomatshini, kodwa izinto ezidityanisiweyo ezisebenzayo ezakhelwe ukwenza phantsi koxinzelelo-ngoko ufuna ngaphezu kwesiseko okanye ivenkile yomatshini. Ufuna i utyalo-mali olukhawulezayo lwemveliso apho i-metallurgy, ijometri, kunye neshedyuli idibana khona. Hayi njengesithembiso. Njengesiqhelo.
