Xa uqala ukujonga ngaphakathi iinkampani zokubumba inaliti yesinyithi, uphando lokuqala luhlala lulwandle lwamabango asondeleyo: ukuchaneka okuphezulu, iijometri eziyinkimbinkimbi, indleko-esebenzayo kwimiqulu ephezulu. Ivula ialam yam ethandabuzayo ngalo lonke ixesha. Umahluko wokwenyani akakho kwikopi yokuthengisa; ingcwatywe kwiinkqubo zomgangatho wevenkile, ukulandelwa kwezinto eziphathekayo, kunye nendlela inkampani ephatha ngayo i-warp edibayo ngenjikalanga yangoLwesihlanu. Abathengi abaninzi bafumana ukulungiswa kwinkqubo ye-MIM ngokwayo, belibala ukuba likhonkco elinye kwikhonkco eliqala nge-feedstock kwaye liphele ngokugqitywa, rhoqo ngomatshini, icandelo. Kulapho ukwahlukana kwenzeka khona.
Umsantsa weSiseko: Apho iMIM isoloko ikhubeka
Nantsi inyani esebenzayo endiyifunde kabuhlungu: a iinkampani zokubumba inaliti yesinyithi esebenza kwindawo engenanto ingumngcipheko. Inkqubo ngokwendalo idala iindawo ezikufutshane-netha-zemilo, kodwa kufutshane-netha yispectrum. Phantse rhoqo, ujonge imisebenzi yesibini. Ndibone iiprojekthi zisihla ngenxa yokuba indlu yeMIM kwafuneka ithumele iinxalenye zomsebenzi obalulekileyo we-CNC, iphulukene nolawulo kwixesha, umgangatho, kunye nonxibelelwano olusisiseko. Ukugqwethwa kwe-sintering kwakungaphakathi kwe-spec, kodwa indawo yobuso bomatshini obulandelayo babungekho, kwaye yonke ibhetshi yachithwa emva komatshini. Ukusilela bekungekho kwiMIM; ibikwi-handoff.
Kungenxa yoko le nto imbali yesiseko yenkampani ibaluleke ngaphezu kwencwadana yayo yeMIM. Thatha i-firm like Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Indawo yabo ayikhokeleli ngetekhnoloji yeMIM ekhanyayo. Endaweni yoko, ikumisela kwiminyaka engama-30 yokuphosa kunye noomatshini. Oko kundixelela into ebalulekileyo: bayayiqonda isinyithi. Bakhe bajongana nolwakhiwo lweenkozo zentsimbi engatyiwayo, uxinzelelo kwialloyi esekwe kwinickel, kunye namaphupha amabi antsonkothileyo, njengoko-ephosa iijiyometri kwakudala phambi kokuqwalasela iMIM. Kubo, ukongeza iMIM ayisiyonto iphambili; yinkqubo ehambelanayo kwincoko ende yokuvelisa. Le mvelaphi isisithintelo ngokuchasene ne-MIM yakudala mgibe wokuphatha indawo eluhlaza njengemveliso yokugqibela.
Ubuchwephesha bezinto eziphathekayo yenye inzuzo ethe cwaka. Xa a iinkampani zokubumba inaliti yesinyithi dwelisa iialloyi ezikhethekileyo njengesakhono, kufuneka umbe. Ngaba kuthetha ukuba batofe iibhetshi ezimbalwa, okanye banazo i-metallurgists eziqondayo ukuba i-alloys esekwe kwi-cobalt iziphatha njani ngeprofayili ye-thermal ye-sintering? Inkampani emiliselwe ekwenziweni kotyalo-mali kunye nokulungiswa kwezi zixhobo sele inalo ulwazi lweziko. Ijiko labo lokufunda le-MIM kunye ne-Inconel limalunga nokubumba kunye nokubophelela, hayi isinyithi esisisiseko. Oko kunciphisa umngcipheko wobugcisa beprojekthi yakho kakhulu.
Isinyanzeliso sokuManyanzelwa: i-CNC njengento eNgathethwano
Makhe sijonge ngokuthe ngqo malunga nee-ops zesibini. Ilungu lesixhobo sotyando, umzekelo. Inkqubo ye-MIM inokwenza umzimba we-lever ontsonkothileyo kakuhle, kodwa imingxunya ye-pivot idinga ukugqitywa kwe-Ra 0.4 kunye nonyamezelo oluyi-± 0.025mm olungayi kufikelela kwi-sintering yodwa. Ukuba umboneleli we-MIM une-CNC yangaphakathi, njenge-QSY igxininisa, inxalenye ayishiyi inkqubo yabo yomgangatho. Ingcali yoomatshini inokusebenza ngokuthe ngqo nenjineli ye-MIM ukuyila izilungiso ze-sintering ezibonelela ngeenkcukacha zomatshini ezifanelekileyo. Bathetha ulwimi olunye. Ndikhumbula imeko ngendlu yesivamvo se-injini ye-diesel apho umgangatho wangaphakathi womsonto wawusilela. Ivenkile yoMACHINE yangaphandle ityhola i-porosity evela kwiMIM. Ivenkile yeMIM igxeka ubuchule bomatshini obungalunganga. Ngomboneleli odibeneyo, loo mdlalo utyholayo uwela kwiqela elinye lobunjineli elisombulula ingxaki, ethe yajika yaba yinto encinci yokwenziwa kwe-feedstock ukuphucula ubugcisa.
Olu hlanganiso lukwatshintsha uyilo lwe-manufacturability (DFM) ingxoxo. Ayisekho handoff elandelelanayo. Yincoko ehambelanayo. Unokuyila into usazi ukuba izakubunjwa, ifakwe i-sintered, kwaye emva koko yenziwe ngoomatshini kwindawo elawulwayo, enengxelo etyebileyo. Iindleko zokungunda okuntsokothileyo ngakumbi kunokulungiswa ngokwenza lula inkqubo ye-CNC kamva. Uninzi oluzimele iinkampani zokubumba inaliti yesinyithi ayikwazi ukunika loo mbono iphelele; ukulungelelaniswa kwabo kumisa kwindawo edibeneyo.
Ngaphaya koko, qwalasela iprototyping kunye nesixhobo sebhulorho. Ngamanye amaxesha, ufuna iiyunithi zovavanyo ezisebenzayo ngaphambi kokuba uzibophelele kwisixhobo esipheleleyo seMIM. Indlu edityanisiweyo inokuhlala isenza iiprototypes zomatshini ukusuka kwisitokhwe sebha ye-alloy ecetywayo, ikunika iipropathi zemathiriyeli ezikufutshane ezifanayo zovavanyo. Yindlela yepragmatic, eyonga iindleko ezithi iivenkile zeMIM zomdlalo osulungekileyo zingakwazi ukuphinda-phinda.
