Xa usiva 'i-ultra precision machining', abantu abaninzi ngokukhawuleza bafanekisela igumbi elicocekileyo, elilawulwa yiqondo lobushushu elinomatshini ohamba ngee-axis omninzi. Leyo yinxalenye yayo, ngokuqinisekileyo, kodwa kulapho imbono ephosakeleyo iqala khona. Ayisiyonto nje yegama lomatshini okanye isisombululo sayo sethiyori. Umceli mngeni wokwenyani, elona candelo likugcina uphaphile ebusuku, libambe unyamezelo lwe-sub-micron hayi kwibhloko yovavanyo olugqibeleleyo lwe-aluminiyam, kodwa kwindawo eqinileyo, i-asymmetrical Inconel 718 turbine component emva kweqhekeza le-30, xa i-thermal drift, ukunxiba kwesixhobo, kunye nobushushu besipholisi buqala ukusebeza endlebeni yakho. Nantso umsantsa phakathi spec sheet kunye nomgangatho wevenkile. Ndibone iiprojekthi ezininzi kakhulu zikhubeka ngokuyiphatha njengento elula 'yokuthenga oyena matshini ubalaseleyo, ufumane awona malungu angcono' equation. Yinkqubo, uqeqesho, kwaye ngokuphandle, intwana yobugcisa.
Isiseko: Iqala phambi kokuba i-Spindle ijike
Awukwazi ukuthetha ngayo ultra precision machining ngaphandle kokuba uqale uthethe ngento oyifaka kumatshini. Apha kulapho amashumi eminyaka yamava ezinto eziphathekayo aye angaxoxiswana. Sisebenza ngobuninzi be-nickel-based kunye ne-cobalt-based superalloys kwiziko lethu. Ezi ayizizo iibhloko zakho ezisemgangathweni ezingama-304. Inkqubo yokuphosa-nokuba kukungunda kweqokobhe okanye utyalo-mali esilwenzayo-ibeka inqanaba. Uxinzelelo lwangaphakathi, ukwakheka kweenkozo, nkqu ne-porosity encinci evela ekugaleleni inokuba sisiphene esiyingozi xa uthatha iipasi ezilinganiswe ngee-microns. Inkqubo egqibeleleyo ye-CNC ayinamsebenzi ukuba i-blank ine-tension efihliweyo ekhupha i-mid-cut. Ke, umthetho wethu wokuqala kukuphatha inkqubo yobuchwephesha njengenyathelo lokugqibela, elibaluleke kakhulu kwikhonkco elide kakhulu. I-Foundry kunye nevenkile yomatshini ayinakuba silos; kufuneka bathethe ulwimi olufanayo lwembali ye-thermal kunye nokunciphisa uxinzelelo.
Ndikhumbula iprojekthi yendlu yoluvo eMonel K-500. Ushicilelo lubize i-0.005mm yokunyamezela indawo yokwenyani kwezinye iibhore ezinzulu, ezinobubanzi obuncinci. Ukuboniswa kotyalo-mali kujongeka kuhle. Kodwa ngexesha lokuqhuba kwenqaku lokuqala, siye safumana ukukhukuliseka okungaqhelekanga. Akukho nto ingako, kodwa ngokwaneleyo ukukrazula inxalenye. Emva kweentsuku ezimbini zokuleqa ijometri yomatshini kunye nokuphuma kwesixhobo, sibuyele kwidatha yokuphosa. Ingxaki yaba sisicombululo somjikelo wokunqanda. Yayingaguquguquki, kodwa ukulungiswa ngexesha lokuphathwa kobushushu kwadala ubunzima obungalinganisekiyo kodwa obungaguqukiyo bomkhombandlela. Ukulungiswa kwakungekho kwikhowudi ye-CNC; yayiyi-tweak yoqwalaselo lokurhwaqela kwiziko ngaphambi kokuba ukuphosa kubone isixhobo somatshini. Yinkqubo yokucinga leyo.
Yiloo nto imvelaphi yenkampani ibalulekile. Ivenkile ethenga nje iibhilikhwe kwishelufu ayinakuze idibane noku, okanye inokuchitha iiveki ilungisa ingxaki engayidalanga. Indlela yethu edibeneyo kwi QSY-ukusebenzisa iminyaka engamashumi amathathu kwi-casting kunye ne-machining-kuthetha ukuba silawula izinto ezahlukeneyo ukusuka ekunyibilikeni ukuya phambili. Kuncinci malunga nokulungisa iingxaki kwaye ngaphezulu malunga nokuyila inkqubo yokuziphepha. Isicwangciso somatshini somzimba wevalvu yentsimbi yesanti yesanti yihlabathi ngaphandle koko kutyalo-mali oluchanekileyo lwecandelo lotyando lwentsimbi, nokuba kuyafana. CNC Machining iziko liqhuba zombini.
UMtshini ungumdlali nje; Inkqubo nguMlawuli
Kulungile, ke unendawo ezinzileyo, enokucingeleka. Ngoku umatshini. I-obsession ihlala ikwimodeli entsha, ekhawulezayo, nechanekileyo.

Umgangatho ehleli kuwo kufuneka udityaniswe kwi-ambient vibration-forklifts, abanye oomatshini, kunye netrafikhi ngaphandle inokuba ngumba.
Emva koko kukho ubushushu. Umgaqo wesithupha kukuba utshintsho lwe-1 ° C kwimitha yensimbi malunga ne-11.5 microns yokwandiswa. Xa usebenza kwi ukuchaneka okuphezulu inqanaba, yintaba leyo. Sigcina ± 0.5 ° C imvulophu kwiseli yethu echanekileyo. Kodwa ayingomoya wegumbi kuphela. Ubushushu besipholisi bulawulwa ngokusebenzayo. I-spindle ifudumele kunye nomjikelo othile ukufikelela kwi-equilibrium ye-thermal. Side sivumele izinto eziluhlaza zihlale esiseleni iiyure ezingama-24 ukuze ziqheleke. Awungomachine nje wesinyithi; ulawula ubunyani bayo bobushushu.
Isixhobo ngomnye umngxuma womvundla. I-off-the-shelf carbide end mills ayiyi kuyinqumla, i-pun ijoliswe. Sithetha abanini besixhobo esijikwe idayimani, silinganisele kwi-G2.5 okanye ngcono. Isixhobo sokuseta ngaphambili asiyonto intle-ukuba nayo; ulungelelwaniso lwayo lubaluleke kakhulu njengeeCMM. Kwaye imbuyekezo yokunxiba izixhobo ayingomcimbi ucwangcisiweyo; luqhubekeko oluqhubekayo, lwexesha lokwenyani olusekwe ekujongweni komthwalo ojikelezayo kunye nohlalutyo lokugqiba komphezulu. Uhlakulela ukuvakalelwa ngayo. Isandi sokusikwa sitshintsha, phantse ngokungaqondakaliyo, ngaphambi kokuba amanani esweni akuxelele. Leyo yinxalenye 'yobugcisa'-ukwazi ixesha lokuthembela kwinzwa kunye nexesha lokuthembela amathumbu akho, eneneni iminyaka nje yokuqatshelwa kwepateni.
Umlinganiselo: Umgwebi ongaxoleliyo
Kulapho amaphupha adibana khona nenyani. Ungayikholelwa impendulo yomatshini wakho wokubeka yonke into oyifunayo, kodwa inxalenye ilungile nje ngokukwazi kwakho ukuyilinganisa. Kwi ultra precision machining, izixhobo zakho ze-metrology kufuneka zibe ngumyalelo wobukhulu obuchanekileyo ngakumbi kunokunyamezela kwakho ekujoliswe kuko. I-CMM enokungaqiniseki okuchaziweyo kwe-microns ye-1.5 ayifanelekanga ukubamba iimpawu ze-5-micron. Sithembele kakhulu kuthelekiso lwamehlo kunye ne-laser scanning kunye nefomu yabavavanyi bejometri ebalulekileyo njengesikhundla sokwenyani kunye neprofayile yomphezulu.
Imeko-bume endiyikhankanyileyo yokwenza oomatshini? Yinyani ngokuphindiweyo kumlinganiselo. Igumbi leCMM linezalo, nolawulo olungqongqo lwe-thermal. Uphatha iindawo ngeeglavu, kungekuphela nje ukugcina ioyile, kodwa ukuthintela ubushushu bomzimba wakho ukuba bungabaphambukisi ngexesha lomjikelo womlinganiselo wemizuzu eli-15. Ndibone i-50mm ye-diameter gauge ye-pin ye-diameter engaphumeleli kwisatifikethi kuba umhloli wayibamba ngesandla esingenanto ixesha elide ngaphambi kokulinganisa.
Ezona zifundo zithobekayo zivela kwimilinganiso yokungavumelani. Sakhe saba nomthengi owala iinxalenye ezisekwe kwidatha ye-CMM yangaphakathi, ngelixa eyethu yababonisa kakuhle ngaphakathi kwe-spec. Emva kweveki yengxwabangxwaba, safumanisa oyena nobangela: ii-algorithms ezahlukeneyo ezifanelekileyo kwiiphakheji zesoftware ye-CMM yokuseka isakhelo sereferensi yedatha. Zombini bezichanekile ngokwemathematika, kodwa bawutolika ngokwahlukileyo umhlaba ongafezekanga wokwenyani. Isisombululo yayikukulungelelanisa iprotocol yokulinganisa kuqala, ngaphambi kokuba kunqunywe inxalenye enye. Ngoku, kwimisebenzi ebaluleke kakhulu, sihlala sisabelana ngezicwangciso zomlinganiselo kwaye sizilinganise. Kwajika ukujongana ngezikhondo zamehlo kwaba yintsebenziswano.
Xa Ingasebenzi: Ixabiso Lokusilela
Akukho mntu uthanda ukuthetha nge-scrap, kodwa ekutyhaleni imida yokuchaneka, ufunda ngakumbi kwizinto ezikhatywayo kunezimpumelelo. Kwangoko, safumana umsebenzi kwiziko lophando elidinga i-beryllium-izibuko zobhedu ezinomphezulu ongcono kune-nanometers eziyi-10. Sicinge ukuba iinkqubo zethu zifakwe ngaphakathi. Asiphumelelanga.
