Xa abantu abaninzi besiva iChina CNC ichaneka machining, into yokuqala ethi gqi entlokweni yabo isoloko inexabiso eliphantsi. Kwaye ngokuqinisekileyo, yinxalenye yebali, kodwa yeyona ilula, eyona maleko ingaphezulu. Incoko yokwenyani, le sinayo emgangathweni wevenkile, imalunga nomsantsa ophakathi kwevenkile eqhuba oomatshini kunye neqondayo. ngokuchanekileyo machining njengenkqubo. Ndikhe ndayibona imizobo evela kubathengi baphesheya kweelwandle apho i-callouts yokunyamezelana iyingubo ± 0.05mm kwibhodi yonke-uphawu olucacileyo lokuba bathenga into yorhwebo, hayi ubunjineli becandelo. Ingqondo yokuba yonke into evela eTshayina yikopi ephantsi ngowona mqobo mkhulu. Inyaniso yeyokuba, indawo ekhuphisanayo apha ikhohlakele, kwaye abasindileyo ngabo baye bafudukela kude ngaphaya kokuba nexabiso eliphantsi. Iivenkile ezihlala zihleli, njengezinye ezindala ezidityanisiweyo zaseQingdao endikhe ndasebenza nazo, ziyayifumana. Ayithethi ngexabiso lesincamathelisi somatshini; imalunga nendlela olilawula ngayo lonke ikhonkco, ukusuka kulwakhiwo lweenkozo ezigayiweyo ukuya kumsebenzi wesandla wokugqibela wokuqhawula. Kulapho ixabiso lokwenyani, kunye neentloko zokwenyani, zihlala khona.
I-Foundry-Machining Link: Apho Ukuchaneka Ngokwenene Kuqala
Le yeyona nto abantu abaninzi abathengayo abakhangela i-Alibaba bayiphosile ngokupheleleyo. Ukuba wenza inxalenye ukusuka ekujuleni okukrwada okanye ukwenza, ukuchaneka kwakho sele kuchaziwe kwakudala ngaphambi kokuba ibhilethi ibotshwe kwi CNC Machining iziko. Ndikhumbula iprojekthi yomzimba wevalve yehydraulic, imathiriyeli yayiyintsimbi ye-ductile. Umzobo ovela kwivenkile eqhelekileyo ujongeka kakuhle, kodwa sabetha eludongeni ngexesha lemveliso yevolumu-imigangatho yomatshini yayiza kubonisa i-porosity ngamanye amaxesha, ibulala umlinganiselo woxinzelelo. Umba yayingengoomatshini; yayiyinkqubo yesiseko. Umgangatho wokunyibilika kunye noyilo lokungunda alwenziwanga lulungele indawo efuna ubuso obugqibeleleyo betywina. Awunakho ukukhupha umngxuma ongaphantsi komhlaba.
Kungenxa yoko le nto imodeli kwindawo efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) iyavakala. Sele besenza umboniso ngaphezulu kweminyaka engama-30 ngaphambi kokuba i-CNC ibe ligama eliqhelekileyo apha. Xa umatshini inxalenye baye baziphosa, njengendlu yempompo yensimbi engenasici, balawula izinto eziguquguqukayo. Bayayazi indlela amaxabiso okupholisa achaphazela ngayo uxinzelelo, zeziphi iindonga ezinokuthi zigqwethe ngexesha lokurhaxa, kwaye baya kulungelelanisa ukuphosa. CNC ukuchaneka machining izibonelelo ngokufanelekileyo. Luhlobo olwahlukileyo lwe-DFM (uYilo lokuVeliswa) iluphu yengxelo. Ingcibi yomatshini inokubuyela emva kwingcungcu yamatye ize ithi, Le mbaleki ibangela indawo enzima apha, singayisusa? Olo ludibaniso luyinzuzo ethe cwaka ongayi kubona kwixabiso lentengo.
Ikwatshintsha umdlalo wezinto eziphathekayo. Indawo yabo ikhankanya i-alloys ezikhethekileyo-esekelwe kwi-cobalt, i-nickel-based. Machining abo akukho nje malunga nokuthenga isiphelo lokusila ebiza. Ukuba inkqubo yotyalo-mali yotyalo-mali lweblade ye-nickel-alloy turbine ayibhalwanga, uya kufumana ubulukhuni obungahambelaniyo okanye ukudityaniswa okuya kuphazamisa isixhobo sakho kwipasi yokuqala. Ukulawula i-genesis yezinto eziphathekayo kunika iqela lomatshini ithuba lokulwa lokucwangcisa ukusika okuzinzileyo, okuchanekileyo. Ngaphandle koko, ungcakaza nje.
Intetho yokunyamezelana: Inkohliso yoMzobo
Wonke umntu ufuna ukunyamezela okuqinileyo. Kodwa ukuzichaza kunye nokuzibamba rhoqo kwimveliso yomxube ophezulu ziihlabathi ezimbini ezahlukeneyo. Umzobo usenokufuna unyamezelo ±0.01mm. Ivenkile enobuchule inokubetha loo nto kwi-CMM kunye nenxalenye yenqaku lokuqala. Uvavanyo lokwenyani luyibambe kwicandelo le-10,000, kubasebenzisi bomatshini abahlukeneyo, ngokunxiba izixhobo, kunye nokwahluka kweebhetshi kwizinto ezingakrwada. Apha kulapho indawo yaseTshayina yenxaki inyeliswa ngokungafanelekanga kwaye nalapho iivenkile ezingcono zizahlulayo.
Indawo yokusilela eqhelekileyo ayingobuchule bomatshini-iJapan yanamhlanje okanye isiJamani CNC Machining amaziko akuyo yonke indawo apha. Yinkqubo yendalo exhasayo. Ngaba inkqubo yolawulo lwezixhobo ingqongqo? Ngaba iqondo lokupholisa liyahlolwa yonke imihla? Ngaba i-CMM ilinganisiwe kwaye ngaba abaqhubi baqeqeshelwe ukuyisebenzisa ngaphaya kokukhanya okuluhlaza/ukuhamba? Ndiye ndangena ezivenkileni ezinemiqolo yoomatshini beDMG Mori egqunywe ngeswarf, kungekho nolawulo lwemozulu. Amalungu aphumayo aya kukhukuliseka kunye nobushushu begumbi. Ukuchaneka ayilolungiselelo lomatshini; luqeqesho lokusingqongileyo kunye nenkqubo.
Umzekelo, ukwenza iifreyimu ezinkulu zentsimbi kwisixhobo sokukhanya. Ubunzima bobushushu bukhulu. Ukuba uyayirhaxa, iyatshisa kwaye iyanda. Awunako ukuyiyeka ihlale usuku ukuze iphole-ishedyuli yemveliso iqinile. Injineli yenkqubo enamava iya kucwangcisa amanyathelo aphakathi okuphelisa uxinzelelo okanye isebenzise isipholileyo ngobuchule ukulawula ukukhula kobushushu ngexesha lokusikwa. Zezi zinto zingathandekiyo, i-tweaks yamava echazayo ngokuchanekileyo machining. Uzifunda ngokukhupha iicastings ezimbalwa ezibizayo, hayi kwincwadana yemigaqo.
Isixhobo kunye nokuLungisa ubuGcisa obuMnyama
Ukuba ufuna ukubona ukuba iphi intliziyo yevenkile yomatshini, musa ukujonga umatshini wabo omtsha we-5-axis. Jonga kwikhabhathi yabo yezixhobo. Ukulungiswa okufanelekileyo kuhlala kusiko, ngamanye amaxesha kukhangeleka kukrwada, kwaye kuhlala kugxeka. Kwiindawo ezintsonkothileyo, ezinomthamo ophantsi, uyilo lokulungisa lungatya ixesha lobunjineli elingaphezulu kunenkqubo yeCNC ngokwayo. Ukulungiswa okungalunganga kuya kuzisa intwasahlobo, ukungcangcazela, okanye ukuvumela inxalenye ukuba itshintshe ngama-microns phantsi kwamandla okusika, ukubulala ukuchaneka kwakho kungakhathaliseki ukuba ikhowudi yakho ilungile kangakanani.
Sakhe saba ne-aluminiyam yokuxhoma inzwa eneengalo ezicekethekileyo, ezigudileyo. Isixhobo sokuqala sisebenzise ii-vises eziqhelekileyo kunye neentambo zeenzwane. Amacandelo aphumelele ukuhlolwa kwe-CMM ngokwe-statically, kodwa phantsi kovavanyo lokungcangcazela kwindibano yokugqibela, basilela. I-machining yayibangela uxinzelelo oluncinci kunye nokuphazamiseka okuncinci okubonise kuphela phantsi komthwalo oguqukayo. Ukulungiswa kwakuyinto ethambileyo yomhlathi oxhasa yonke iprofayili yecandelo, ukulungelelanisa iimpawu ezibalulekileyo kwisethingi enye. Izinga le-scrap rate liye lehla, kodwa ixabiso lokulungisa linyukile. Ukuchaza ukuba iindleko kumthengi obona kuphela ibhloko ye-aluminium + ixesha lomatshini ngumngeni oqhubekayo.
Le ngenye indawo apho abavelisi abadibeneyo banomgca ofihlakeleyo. Ivenkile efana ne-QSY, ejongene nokufakwa kwayo, ihlala inokuyila ukuphosa ngamanqaku adibeneyo okanye iimbambo ezomelezayo ezinceda umatshini, ezithi kamva zisuswe. Yimbono epheleleyo yenxalenye njengento eyenziweyo, kungekhona nje imodeli ye-CAD eya kuthatyathwa kwibhloko yesitokhwe.
Isandla soMntu kwiNkqubo yeDijithali
Oku kunokuvakala njengenkohliso kwiminyaka yobudala be-automation epheleleyo, kodwa kumxube ophezulu, ukuntsonkotha okuphezulu China CNC echanekileyo machining, igcisa elinobuchule lisengumqobo—ngendlela elungileyo. Umfana owenza ukutshatyalaliswa kokugqibela, ukukrazula ngesandla kwetywina eligqibeleleyo (okwenziwayo kubuso obuthile bevalve enkulu), okanye indibano ekhethiweyo yezinto ezihambelanayo. Ndikhe ndabona umsebenzi esebenzisa intonga elula yobhedu kunye nehamile ukuze alungise ngobunono intsimbi enkulu, eyenziwe ngoomatshini kumakhulu ambalwa eemilimitha ukuze ilungelelaniswe—imvakalelo ekungekho irobhothi enayo ngoku.
Owona mngcipheko kwimveliso yaseTshayina kukudityaniswa kolu lwazi lobugcisa. Iinkosi ezindala ebezinokumamela isikwe zikuxelela ukuba i-insert iyachopha ziyarhola. Uxinzelelo lokutyhala abaqhubi abancinci ukuba balayishe nje / bakhuphe iinxalenye kunye nokuleqa i-metrics yemveliso iphezulu. Iivenkile ezigcina ezinye zezo zobugcisa, ezivumela oomatshini babo abakhulu ukuba badibanise ukutya kunye nesantya kwi-fly esekelwe kwisandi kunye nombala we-chip, bavelisa amacandelo angaguqukiyo, aphezulu. Yinto engabambekiyo. Awukwazi ukuyiphicotha kuluhlu lokukhangela umgangatho, kodwa ungayibona kulawulo olusezantsi lwenkqubo yobalo (SPC) ekuhambeni kwexesha.
Oku kunabela kwi-post-processing. Inxalenye yentsimbi ecocekileyo eyenziwe ngoomatshini ingonakaliswa ngokugqugqisa okunobundlongondlongo okanye okungahambelaniyo. Ukwazi ulandelelwano lwegrits, uxinzelelo lokusebenzisa, kunye nendlela yokuphatha imiphetho ukugcina ingqibelelo ye-dimensional-bonke bubuchule besandla. Ihlala iyindawo yokugqibela, eyona nto ichukumisayo yomntu kwi CNC ukuchaneka machining chain, kwaye ichaphazela ngokupheleleyo umsebenzi kunye nomgangatho obonwayo.
Unxibelelwano: I-Bottleneck yokwenyani
Isakhono sobugcisa sisoloko sikhona. Inqanaba lokuqhawula phantse lihlala linxibelelwano. Umzobo we-2D onemilinganiselo ebalulekileyo engekhoyo. Imodeli yeCAD eneekona zangaphakathi ezingenakulinganiswa. Ikhonkco le-imeyile apho ukugqiba komphezulu kungachazwanga njenge-Ra okanye i-Rz, ekhokelela kwindawo esebenza ngokugqibeleleyo yaliwe. Ukuncipha kwexesha lezowuni kuyenza mandundu oku. Ingcaciso ekhawulezayo ethatha imizuzu emi-5 ukuba ukwisakhiwo esifanayo inokumisa iprojekthi iiyure ezingama-48.
Ezona projekthi ziphumeleleyo endizilawuleyo zibandakanya unxibelelwano olugqithisileyo. Singayibuyisela imizobo ephawulweyo, hayi ngemibuzo nje kuphela, kodwa neengcebiso: Le radiyasi inokunyuswa ukuya kutsho kwi-R3 ukusuka kwi-R1.5 ukuvumela isixhobo esisemgangathweni, ukonga iindleko kunye nexesha lokukhokela ngaphandle kokuchaphazela umsebenzi. Okanye, Ngaba oku kunyamezelana kunokunyenyiswa ukuya ku-±0.1mm? Ikubuso obungengabo ukukhwelana kwaye ingafuna i-op yesibini yokusila ku-±0.02mm. Le ndlela yokubonisana iguqula ubudlelwane ukusuka kumthengisi-umxumi ukuya kwiqabane. Oku kubonisa ukuba awungomtyhili-qhosha nje; usebenzisa ubukrelekrele bokwenza kuyilo lwabo.
Kwinkampani esebenza nabathengi bamazwe aphesheya, njengabaninzi eQingdao, oku kukugaya kwemihla ngemihla. Ayikokuba nezona zithethi zibalaseleyo zesiNgesi; imalunga nokuba neenjineli zeprojekthi ezinokutolika injongo yobunjineli ibe yinyani yokuvelisa, kwaye emva koko banxibelelane ngemiqobo kunye nokhetho emva ngokucacileyo. Olo umaleko lulo olujika umntu onobuchule CNC Machining ivenkile ibe ngumthombo othembekileyo we ngokuchanekileyo machining. Yeyona nto incinci izenzekelayo, eyona nxalenye ibaluleke kakhulu kuwo wonke umsebenzi. Kwaye ngokunyaniseka, yeyona nxalenye kunzima ukuyilungisa, naphi na emhlabeni.
