Lapho onjiniyela bayacacisa imboni yezingxenye ze-powder metallurgy izixazululo zamavalvu asebenza ngogesi, izindlu zokumpompa, noma izinsimbi zewintshi ezigqoke kakhulu, azithengi nje izingxenye ezithile—zivikela ukuqina kohlangothi ngaphansi kwengcindezi yebha engu-350, ubuqotho be-microstructural ngemva kwemijikelezo yokushisa engu-10,000, kanye nokubekezelela kokuqeda phezulu kuqine kuno-±0.005 mm. Abahlinzeki abaningi bathembisa ukunemba. Bambalwa abayilethayo—ikakhulukazi kuma-alloys e-cobalt-nickel afana ne-AMS 5387 noma ama-superalloy ebanga le-T800 lapho ukuxoxa ngomshini, ukuhlanekezela kwendawo ethinteke ukushisa, kanye nokwahluka kokuqina kwe-batch-to-batch kuphazamisa ukukhiqizwa njalo.
Sizibonele mathupha: indawo kawoyela yaseNyakatho Melika i-OEM ibambezele ukusebenza amasonto angu-11 ngenxa yokuthi umlomo wombhobho we-cobalt alloy “oqinisekisiwe” waqhekeka ngesikhathi sokuhlolwa kwengcindezi—hhayi ngenxa yokushiyeka kokuklama, kodwa ukwakheka okusanhlamvu okungahambisani kuwo wonke ukusakaza. Elinye iklayenti lilahle u-62% wezindlu ezenziwe ngomshini zephampu ye-piston ngemva kokwelashwa okushisa ngenxa yokuhlukaniswa kwekhabhoni okungalawuleki kunsimbi eyisisekelo. Lawa akuwona amacala. Ziyizimpawu zamandla ahlukene—lapho ukulingisa, ukwenziwa kwemishini, nokuqinisekiswa kwensimbi kwenzeka kubathengisi abathathu, ngamunye ulungiselela izindleko noma isivinini, hhayi ukusebenza komsebenzi.
Yingakho ukulawula inqubo edidiyelwe kubaluleke kakhulu kunanoma yisiphi isitifiketi esisodwa. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke ipulaki ye-cobalt alloy, ingxenye yepompo ye-AMS 5387, noma ukusakaza kwensimbi engagqwali kuqala ngokulandeleka kwempahla eluhlaza kuze kufike kunombolo yokushisa kanye nombiko wokuhlolwa komshini—hhayi nje ama-invoyisi abahlinzeki. Sihlanganisa ama-specs wezinto ezibonakalayo ngabakhiqizi be-alloy abaqinisekisiwe, senze ukuhlaziya okungenayo kwe-spectrographic ku-100% wamabhilidi e-cobalt-nickel, futhi siqinisekise i-microstructure nge-metallography ngaphambi kokuthi kuqale ukwenziwa kwemishini enzima. Akukho ukucabanga. Awekho ama-handoffs. Ubufakazi obubhaliwe bokuthi impahla oyi-ode yizinto ozitholayo.
Ukuhlanganiswa okuqondile akuyona i-jargon yokuthengisa lapha—yindlela esibamba ngayo ama-callouts angu-±0.01 mm GD&T kumarola aphakathi nendawo angajwayelekile kumawintshi emoto yobunjiniyela. Isikhungo sethu esithobela i-ISO siqhuba ukufakwa kwezimali kokufakwa kwe-cobalt odongeni oluncane, ukufakwa kwesihlabathi kwezisekelo zephampu ezinobubanzi obukhulu, kanye nomshini we-CNC we-5-axis—konke ngaphansi kophahla olulodwa. Lokho kusho ukuthi ithimba elifanayo le-metrology liqinisekisa ubukhulu obunjengobusakazwa, lihlola ama-bores abalulekile maphakathi nomshini lisebenzisa ama-Zeiss CMM, futhi lenze ukuhlola kokugcina okusebenzayo ngokumelene namazinga okugeleza ashiwo yikhasimende namajika etorque. Lapho iklayenti licela umzimba wevalvu yengxubevange ye-T800 yangokwezifiso enamashaneli okupholisa angaphakathi, siqedele ukuqinisekiswa kwe-prototype ezinsukwini ezingu-14—hhayi ngoba saphuthuma, kodwa ngenxa yokuthi ukusakaza idatha yokuncipha kufakwe ngokuqondile kusinxephezelo sendlela yamathuluzi ye-CAM, sasusa izihibe ezimbili zokuphindaphinda.
- Ayikho i-metallurgy "yebhokisi elimnyama": Konke ukulingwa kwe-cobalt-nickel kanye ne-high-alloy kufakwa isisombululo + ukuguga nge-AMS 2750 ngayinye, nezingodo zomlilo ezilondolozwe iminyaka eyi-10
- Akukho ukukhukhuleka kwe-dimensional: I-CMM esenkambisweni ihlola ezigabeni ezintathu—ngemuva kokubi, ukuqeda kancane, kanye nokudlula kokugcina—kugwema iphutha elikhulayo.
- Akukho ukucaciswa okucacile: Ithimba lethu lonjiniyela lihlaba umkhosi izingxabano ze-GD&T ngaphambi kokucaphuna—njengokubuza ukuthi kungani ukubekezelela indawo okungu-±0.002 mm kusebenza kusici sobubanzi obungu-200 mm kundlu esakazwa isihlabathi
- Azikho izimanga zokulethwa: Ukuhlelela ukugeleza komsebenzi okunciphile kukhiya ezikhathini zokuhola zama-oda evolumu ephakathi (ama-50–500 ama-pcs) ngaphambi kokwamukelwa kwe-PO—azikho izigatshana “ezingaphansi kwamandla”
Abanye bangase baphikise ngokuthi izikhungo ezikhethekile noma izitolo ezizinikele ze-CNC zinikeza ubuchwepheshe obujulile. Kodwa ubuchwepheshe obungenawo umongo budala izindawo eziyimpumputhe. Isazi sokusakaza ngeke silindele ukuthi ukucindezeleka okusalayo okuvela ekugqinsileni okungalingani kodonga kuthinta kanjani i-ovality yangemva komshini endaweni ye-valve yokucindezela. Uchwepheshe we-CNC angase athuthukise isikhathi somjikelezo ngaphandle kokuhlola ukuthi amandla okusika ayawedlula yini amandla esivuno sepulaki ye-cobalt efakwe ukushisa. I-QINGDAO QIANGSENYUAN ivala lelo gebe—ngoba onjiniyela bethu baye baklama, basakaza, benza ngomshini, futhi bahlola ngaphezu kwezingxenye zesistimu yephampu ezihlukile ezingu-1,200 kusukela ngo-2015. Siyazi ukuthi i-AMS 5387 idinga nini amanani okuphakela kancane ukuze igweme ukuqina komsebenzi—futhi uma i-T800 ingxubevange izuza ekukhululekeni kokucindezeleka kokugcina.
Uma sibheka phambili, ukugxila kwethu kwe-R&D akukhona emishinini emikhulu noma kumakhathalogi abanzi. Kusezinhlelweni ezixubile: ukuhlanganisa ukufakwa kwe-investment-shape ene-net-shape ne-electrochemical machining yezici zangaphakathi okungenakwenzeka ukufinyelelwa kuzo ngamathuluzi avamile; ukushumeka ukuqapha kwezinga lokushisa kwesikhathi sangempela ekubumbeni ukubumba ukuze kuhlobaniswe idatha yegradient eshisayo nokusabalalisa kokuqina kokuqina okuncane; ukukhulisa i-EN 10204 3.2 ukufakwa kwesitifiketi ukuze kufakwe imibiko egcwele yamakhemikhali + emishini + ye-NDT yayo yonke indawo ethunyelwayo. Ngoba ezinhlelweni zokusebenza ezibalulekile—kusuka kuma-hydraulic manifolds angaphansi kolwandle ukuya kumasistimu omjovo kaphethiloli okucindezela kakhulu—umehluko phakathi “kwemisebenzi” nokuthi “ngeke yehluleke” uhlala emininingwaneni oyilawulayo, hhayi leyo oyinikezayo.
Uma iphrojekthi yakho elandelayo idinga imboni yezingxenye ze-powder metallurgy ukuqina—hhayi nje ivolumu—qala ngokulandeleka kwezinto, funa ubufakazi be-metrology eqhubekayo, futhi ugcizelele impendulo yobunjiniyela ngaphambi kokuphothula imidwebo. Izingxenye ozicacisayo namuhla zizosebenza lapho ukwehluleka kungeyona inketho. Khetha umlingani ophatha konke ukubekezelelana njengenkontileka.
