Iyo inzu ya pompe hydraulic yananiwe kuri 3,200 psi - cyangwa cobalt alloy nozzle yamenetse mugihe cyamagare yubushyuhe - intandaro ni gake. Ni ugutunganya neza uruganda rukora neza: gutandukana kwinshi muri geometrie, imiterere yintete idahuye uhereye kumashanyarazi, cyangwa ibikoresho bitagenzuwe neza. Twabibonye kumugabane wa gatatu: ibice byatsinze igenzura ryingingo ya mbere ariko binanirwa gukora ibizamini nyuma yamasaha 47 yakazi. Niyo mpamvu gukora-kwihanganira cyane gukora biterekeranye nimibare ikaze ku gishushanyo. Byerekeranye no kugenzura-ukoresheje ibikoresho, inzira, nibyemezo byabantu.
Kuki "Kworoherana Kworoherana" bisobanura ibintu bitandukanye mubikorwa
Kwihanganirana gukabije ntabwo ari umubare numwe. Ni imbogamizi ya sisitemu. Uburebure bwa 0.005 mm kuri AMS 5387 cobalt alloy pompe igice gisaba imyitwarire itandukanye kuruta kwihanganira kimwe kumashanyarazi make. Kubera iki? Kuberako cobalt ivanze ikora-ikaze cyane, igahinduka munsi yigitutu cyibikoresho, kandi ikagumana imihangayiko yimbere keretse ubushyuhe bwakorewe * hagati ya * gukomera no kurangiza. Twigeze gukora amazu 12 ya pisitori ya pisitori ya pisitori kubera ko gahunda ya mbere ya CNC yirengagije coefficient zo kwagura amashyuza mugihe cyo guhuza imirongo myinshi - bivamo 0,018 mm ya axial yiruka mubushyuhe bwo gukora. Gukosora ntibyatinze igipimo cyibiryo. Yashyizemo indishyi zigihe-nyacyo muri G-code no kugenzura hamwe na CMM ikorerwa kuri 35 ° C, ntabwo ari 22 ° C.
Bane Bidashobora kuganirwaho kubutumwa-Ibyingenzi Byuma
Ibisobanuro nyabyo bitangira mbere yuko chip ya mbere iguruka. Ukurikije imyaka 11 yo kubyara ibicuruzwa byumuvuduko, imashini ya shitingi ya winch, hamwe nibikoresho bya T800 bidasanzwe, ibi bine bigenzura gutandukanya ibicuruzwa byizewe nabacuruzi bemera ibyago:
- Igisekuru cyibikoresho - ntabwo ari icyemezo gusa: Twakomotse kuri bilet ya AMS 5387 hamwe na raporo yikizamini cyuzuye, ariko kandi twemeza buri cyiciro dukoresheje spark spectrometry * na * ikarita ishushanya ibice. Umubiri umwe wumukiriya wiburayi werekanye kwambara imburagihe kuko uwabitanze yemeye "muri spec" itandukaniro rya karubone-0,02% itandukaniro ryatumye karbide itandukana. Twanze ibyiciro aho karubone irenze ± 0.005%.
- Ihame ryimiterere binyuze mugutunganya imvange: Urufatiro rwa pompe yumusenyi akenshi rugoreka mugihe cyo gutunganya bwa nyuma. Igisubizo cyacu? Stress-yorohereza casting * nyuma ya * CNC ikaze, hanyuma ukore kurangiza kurangiza nyuma yo kugenzura imihangayiko isigaye hamwe na X-ray itandukanya ibice by'icyitegererezo. Ibi byagabanije ibikorwa byintambara bijyanye na 63% kubinyabiziga bya injeniyeri kuri sisitemu ya winch.
- Gushyira mu bikorwa GD&T - ntabwo ari ugusobanura: Iyo igishushanyo cyerekana kwihanganira imyanya mm0.01 mm ugereranije na datum axis, ntidutekereza ko umukiriya yashakaga kuvuga "hafi." Twubaka ibikoresho bya granite byabugenewe bifunga igice kuri datum zerekanwe - kandi tugapima dukoresheje Zeiss Contura G2 RDS hamwe na 0.3 µm probe isubirwamo. Oya "funga bihagije."
- Traceability yatetse muri buri gikorwa. Niba kunanirwa bibaye mumurima, dutandukanya imizi muminota 90 - ntabwo ibyumweru.
Igiciro Cyihishe Cyimashini "Birahagije"
Abaguzi bamwe bashyira imbere igiciro gito cyibiciro kuruta inzira. Babona ibyo bishyura - ariko ntabwo buri gihe bahita. Uruganda rukora ibikoresho bya peteroli yo muri Amerika ya ruguru rwahindutse rutanga igiciro gito cyo guteranya ibyuma bidafite ingese. Igiciro cyambere cyagabanutseho 22%. Mu mezi 8, kunanirwa mu murima byagaragaye: 17% by'ibice byasohotse ku ngingo ya flange kubera ubuso budahuye bwo kurangiza Ra agaciro (bapimye 1.8-3.4 µm v. Bisabwa ≤1.2 µm). Gukosora? Kongera gushushanya ibimenyetso bifatika no kwinjiza $ 412,000 mumirimo ya garanti. Precision ntabwo ihenze. Ibintu bidahwitse.
Niki Ubufatanye Bwukuri-Kwihanganirana busa
Bitangirira ku gishushanyo cyo gusubiramo - ntabwo ari PO. Iyo abakiriya batwoherereje GD & T-uburemere bwibishushanyo mbonera byamazu cyangwa inzu ya silinderi, ntabwo tuvuze gusa. Turashyira ahagaragara ingaruka zo gukora: "Uku guhamagara mm 0.008 guhamagara kuri mm 320 mm x 180 mm bisaba gusya * nyuma yo kuvura ubushyuhe - bitabaye ibyo kugoreka bizarenga kwihanganira. Turashobora guhinduka kuri mm 0,015 hamwe nuburinganire bwubutaka aho?" Twabujije 217 igishushanyo mbonera muri ubu buryo. Ikigo cyacu cyubahiriza ISO gikora icyarimwe gushora imari, 5-axis ya CNC gutunganya, hamwe no kuvura ubushyuhe bwa vacuum - kubwibyo rero nta ntoki zo hanze zangiza igenzura. Igenzura rya nyuma ntabwo ari irembo. Birakomeje: kugenzura ibikoresho byinjira, murwego rwo kwemeza CMM nyuma ya buri gikorwa, hamwe no gupima imikorere ikora kuri 1.5x yagabanijwe kumuvuduko wakazi.
Gukora neza uruganda ubushobozi ntibupimwa muri spindle RPM cyangwa imyaka yimashini. Byaragaragaye iyo T800 ishingiye kuri cobalt nozzle irokoka 14,000 yumuriro utarinze microcracking-cyangwa iyo inzu ya pompe ya piston itanga umuvuduko uhoraho kuri 4500 psi mumezi 18. Ukwo kwizerwa guturuka mubikorwa byanditse, disipuline ya metallurgjiya, no kwihanganira zeru kubitekerezo. Kuri ba injeniyeri bagaragaza ibice aho gutsindwa bisobanura igihe cyo gutinda, ibyago byumutekano, cyangwa ibihano byateganijwe: precision ntabwo ari ibisobanuro. Ni sisitemu y'imikorere.
