Xa umntu esithi ngokuchanekileyo CNC iinkonzo machining, lo mfanekiso upeyinta ntoni? Kubantu abaninzi abathengayo kwi-Intanethi, yifektri ecwebezelayo, ezenzekelayo etshica iindawo ezigqibeleleyo. Inyani, le ndiyiphile iminyaka, imbi. Kumalunga nomsantsa phakathi kwemodeli ye-CAD ekuthembisayo kwaye yintoni i-chunk ye-17-4PH engenasici eyenzayo phantsi komsiki. Imalunga nezigqibo ezithe cwaka ezenziwe ngo-2 AM ukubamba loo ±0.0005 ukunyamezelana kungekuphela nje kwindawo enye, kodwa kugqatso lwamakhulu amahlanu. Kulapho inkonzo yokwenyani iqala khona-emva kokuba ikhowuti yamkelwe.
Isiseko: Iqala ngokuCasa
Awukwazi ukuthetha ngayo ngokuchanekileyo CNC machining kwimeko yethu ngaphandle kokuqalisa ukuya phezulu. Inkqubo egqibeleleyo yomatshini ayinamsebenzi ukuba ukuphosa okukrwada kune-porosity efihliweyo okanye ubuninzi bodonga olungahambelaniyo. Ndiyibone amaxesha amaninzi kakhulu. Yiyo loo nto indlela yethu kwi-QSY idityanisiwe. Besisenza iqokobhe lokungunda kunye nokuphosa utyalo-mali amashumi amathathu eminyaka, ke ngelo xesha ukuphosa okufana nendlu yempompo entsonkothileyo okanye umzimba wevalvu ufika kumgangatho we-CNC, sele siyayazi ibhayografi. Siyazi ukuba i-316L yaqiniswa njani i-stainless, apho uxinzelelo lunokuba khona. Le asiyothiyori kuphela; ithetha ukuba singakwazi ukulungelelanisa kwangaphambili ukulungiswa okanye iindlela zesixhobo ukuze siphendule loo mahluko kancinane ukusuka kwimodeli yesiqhelo. Ukwenza umdlalo webhola owahlukileyo—awulwi nezinto ezingaziwayo zomnye umntu.
Lo ngumgibe oqhelekileyo kubathengi. Bafumana ukuphoswa ngexabiso eliphantsi kumthengisi omnye kwaye bayithumele Iinkonzo zoomatshini ze-CNC kwenye indawo, silindele umlingo. Umchwephesha ufumana indawo enamabala aqinileyo ukusuka ekupholiseni okungalinganiyo okanye ukufakwa kwesanti kanye kwindawo ebaluleke kakhulu yokutywina. Izitali zemisebenzi, iminwe iyakhonjwa, ibiza ibhaluni. Inxalenye yenkonzo ilahleka ekuguquleleni. Indlu edibeneyo efana ne-QSY ithatha loo mngcipheko ngaphakathi. Iqela labasunguli kunye nomphathi wezobuchwephesha bathetha ulwimi olufanayo kuba bakwisakhiwo esinye, bejonge kumhambi omnye womsebenzi.
Thatha i-alloys ezikhethekileyo, njenge-nickel-based based (cinga i-Inconel 718). Ukuzitshiza kuliphupha elibi ukuba ubaphatha njengentsimbi ethambileyo. Kodwa ukuba ubaphosile, uyasiqonda ngokusondeleyo ukwakheka kwabo okuziinkozo, ukuziphatha kwabo nzima. Uyazi ukuba ubushushu obuvela ekujuleni buchaphazela ukusebenza kweendawo ezithile. Ngoko ke isicwangciso sakho se-CNC secandelo le-inconel ye-inconel turbine iya kwahluka kakhulu-i-SFM ecothayo, amabakala athile e-carbide, mhlawumbi nolandelelwano olwahlukileyo lwemisebenzi-xa kuthelekiswa nokuyicoca kwibar eyenziweyo. Olo lwazi lubhakiwe kwinkqubo ukusuka kusuku lokuqala.
Ukunyamezelana asingomanani nje kwiShicilelo
Nantsi inyani esebenzayo: nabani na unomshini omnye wokunyamezelana okuphambeneyo kwilebhu elawulwa yimozulu ngomatshini omtsha. Inkonzo ichazwa ngokuyenza ngokuqhubekayo, kwishedyuli, kwibhetshi yokuvelisa. Ndikhumbula umsebenzi we-hydraulic manifold block, intsimbi edityanisiweyo, efuna ii-callouts ezikwimo yokwenyani ngaphakathi kwe-0.05mm kuthungelwano lwamazibuko agrunjiweyo. Umceli mngeni wawungeyonxalenye yokuqala. Yayikugcina oko ngokunxitywa kwesixhobo, ukuqhutywa kwe-thermal kumatshini ngaphezulu kweyure ezi-8, kunye nokwahluka kwemizuzu kwi-castings.
Kuye kwafuneka ukuba sakhe isixhobo esinikezelweyo esibhekiselele kwiimpawu zedatha ye-as-cast, hayi ezona zifanelekileyo. Emva koko, siye sasebenzisa inkqubo yokukhangela kwi-Okuma yethu ye-CNC yokusila ukujonga iindawo ezibalulekileyo kwiindawo ezili-10, sibuyisela ngokuzenzekelayo. Leyo yinkonzo-ixesha lobunjineli elitshisiweyo kuyilo lwenkqubo umthengi angaze alibone kwinto yomgca we-invoyisi ngokuchanekileyo machining. Bafumana nje ipalethi yamalungu afanelekileyo onke, ngalo lonke ixesha. Ukuba awuboneleli ngela nqanaba lobunjineli benkqubo, uyivenkile yoomatshini, hayi umboneleli wenkonzo ochanekileyo.
Kwaye ngamanye amaxesha, kufuneka utyhale umva. Injineli eselula yakha yachaza ukunyamezela ± 0.001 kuyo yonke imilinganiselo yangaphandle engabalulekanga yendlu enkulu yentsimbi. Yayiyinxalenye yezithambiso, ngokusisiseko. Ukusebenzisa elo nqanaba le ukuchaneka kwe-CNC kuyo yonke indawo ngekuphindaphindeke kathathu iindleko kunye nexesha. Inkonzo yethu iquka umnxeba wokuchaza: Jonga, masibambe oko kubuso obunyukayo kunye nokubhoreka, kodwa masiphumle okuseleyo kunyamezelo oluqhelekileyo lwezorhwebo. Iyakukongela ama-40% kwaye ikufumane iiveki ezimbini ngokukhawuleza. Olo thethwano luyinxalenye yephakheji. Yakha intembeko kwaye ibonisa ukuba ucinga ngeprojekthi yabo iyonke, hayi nje ixesha lakho lokuphotha.
Isixhobo Siyalela uMdaniso
Ukusebenza ngezixhobo ze-QSY zisebenza ngokukhethekileyo-ukusuka kwiintsimbi eziqhelekileyo ukuya kwii-alloys ze-cobalt ezingaqhelekanga- kuthetha ukuba incwadi yakho yokudlala idinga imiqulu emininzi. Oomatshini bentsimbi abangwevu njengebhotolo, kodwa uthuli lwegraphite lufika kuyo yonke indawo, ludala umonakalo kumagquma endlela kunye nezikrufu zebhola ukuba ivenkile yakho ayilungiselelwanga oko. Siye sanikezela ngezowuni kunye neenkqubo zokutsala oko. Insimbi engenasici, njenge-304 okanye i-316, imalunga nokulwa nokuqina komsebenzi. Udinga izixhobo ezibukhali, iraki elungileyo, kwaye awunakukwazi ukusivumela isixhobo sihlale. Sisingqisho osiphuhlisayo.
Emva koko utsibela kwinto efana neMonel okanye iHastelloy. Isilo esahlukileyo ngokupheleleyo. Iitshiphusi azophuki; ziphuma zinentambo kwaye zomelele njengetshungama. Ziyakwazi ukudibanisa kwi-insert kwaye zibangele ukusilela kwintlekele. Apha, inkonzo ikwiinkcukacha ezincinci: i-high-pressure coolant ejolise ngqo kumda wokusika kunye nokukhupha iitshiphusi, i-helix end mills ukuphazamisa ukungcangcazela kwe-harmonic, kunye neresiphi ekhethekileyo yokutya / isantya esihlala sivakalelwa kukuba i-counter-intuitively inobundlongondlongo. Ufunda oku ngokonakalisa izithuba ezimbalwa ezibizayo, ngokungafihlisiyo. Leyo yinxenye yeminyaka engama-30 oyibonayo kwisiza se-QSY-lithala leencwadi zezifundo ezifundwe nzima kusapho ngalunye lwezinto.
Ndikhumbula iprototype yevalve yokulungisa imichiza kwi-alloy esekwe kwi-cobalt. Ushicilelo lufuna ukugqiba kwesibuko kwisitulo esicinyiweyo. Yonke indlela yomgangatho wokugudisa ayiphumelelanga; Isixhobo sasingakwazi ukugruzuka kakhulu. Siye sagqiba ekubeni siphuhlise isiko lokuhamba komatshini wokuhamba kwe-micro-abrasive emva komsebenzi we-CNC. Ibingekho kumda wokuqala, kodwa bekuyimfuneko ukuhlangabezana nenkcazo yokusebenza. Elo licala elingenamdla Iinkonzo zoomatshini ze-CNC—ukusombulula iingxaki nomxhasi, hayi kubo kuphela.
Xa Ukuchaneka Kudibana nokuhanjiswa
Kulapho iivenkile ezininzi ziwa khona. Bangakwazi ukubetha uphawu lomgangatho, kodwa abanakuyenza ngevolumu okanye ngexesha. Ukuchaneka ayingomlinganiselo nje wobukhulu; sisithembiso sokuqikelela. Utyalo-mali lwethu kumaziko omatshini aneepali ezininzi ezithe tyaba yayingeloxesha nje lesantya. Yeyokuqhubekeka. Ngelixa ipalethi enye iqhuba umjikelo weyure ezi-4 kwibhetshi yezixhobo ezingenasici, umqhubi useta isixhobo esilandelayo somsebenzi wentsimbi ephoswe kwenye ipalethi. Umsonto akayeki. Kumxhasi, oku kuthetha ukuba umhla wokuhanjiswa kwawo uqinile.
Kodwa neyona nkqubo igqwesileyo ibetha i-snags. Isixhobo siqhawuka ngokungalindelekanga. I-casting inesiphene ebesingabonakali de kwasikwa okokuqala. Inkonzo ichazwa yimpendulo. Ngaba uyayifihla kwaye unethemba lokufumana? Okanye ngaba unxibelelana ngokukhawuleza? Senze umkhwa wokunxibelelana kakhulu. I-imeyile ekhawulezayo enefoto: Kufunyenwe umngxuma wesanti kwinxalenye ye-3 kwisikhululo B. Inokuhlangulwa ngokulungiswa kwe-weld, iyakongeza iiyure ezisi-8. Ukuqhuba ngaphandle kokuba uyalelwe ngenye indlela nge-5 PM. Igcina intsebenziswano yokwenene. Abathengi bayakuxabisa ukungafihli, nokuba ziindaba ezimbi. Bayazi ukuba abatyiswa ngomgca.
Esi singqisho sokusebenza sibalulekile kumashishini esiwasebenzelayo—i-oyile nerhasi, iimpompo, oomatshini abanzima. Icandelo elilibazisekileyo elenziwe ngoomatshini lingabamba umgca wokuhlanganisa wezigidi ngezigidi zeedola. Ubunzima baloo nto buvakala kumgangatho wevenkile. Iguqula umsebenzi ekubeni wenze iinxalenye nje ube likhonkco elibalulekileyo kunikezelo lwekhonkco lomnye umntu. Olo xanduva lubumba sonke isigqibo, ukusuka kuwuphi umsebenzi olayishwa ecaleni kobungakanani besixhobo esisigcina kwishelufu kwizinto ezibaleka kakhulu.
Ukuxhawula ngesandla kweDijithali
Ekugqibeleni, isiphelo sangaphambili. Umthengi onokubakho uhlala kwindawo efana tsngtaocnc.com. Bafuna ikowuti a ngokuchanekileyo CNC machining umsebenzi.
