Kwimveliso yemizi-mveliso, ingakumbi kwiindawo ezineemfuno zokuchaneka okuphezulu nokuqhubekeka, iqonga lokuhamba nge-gantry echanekileyo ye-XYZT lidla ngokufuna ukusebenza phantsi komthwalo omkhulu kunye nokusebenza ixesha elide okuqhubekayo. Ngeli xesha, ukuqina kwezinto ze-granite kuye kwaba yinto ephambili ekuqinisekiseni ukusebenza okuzinzileyo kweqonga.
Uzinzo lwesakhiwo luqinisekisa ukuqina
Emva kweebhiliyoni zeminyaka yotshintsho lwejoloji, iikristale zangaphakathi zeminerali zilungelelaniswe ngokusondeleyo, zenza isakhiwo esixineneyo nesifanayo. Phantsi kweemeko zomthwalo ophezulu, izinto eziqhelekileyo zezinto zinokubangela ukuguquka kwesakhiwo sangaphakathi ngenxa yoxinzelelo, okubangela ukuchaneka okuphantsi okanye kwanokonakala kweqonga. Izinto zegranite zinokujamelana lula nemingeni yomthwalo ophezulu ngenxa yamandla azo aphezulu oxinzelelo. Idatha yophando ibonisa ukuba amandla oxinzelelo lwegranite esemgangathweni ophezulu anokufikelela kwi-200-300MPa, enokumelana noxinzelelo lwentsimbi eqhelekileyo ngaphandle kokuguquka okubonakalayo. Ukuthatha ishishini elikhulu lokwenza izinto zeenqwelo moya njengomzekelo, iqonga lokuhamba kwe-XYZT ngobuchule be-gantry elisetyenziswa yinkampani liyaqhubeka nokuxhasa izinto zegranite ngokuthe chu xa kusetyenzwa isingxobo senjini yenqwelo moya esinobunzima beetoni ezininzi. Ngexesha lenkqubo yokucubungula eqhubekayo ukuya kuthi ga kwiiyure ezili-10, impazamo yokuthamba kweqonga ihlala ilawulwa ngaphakathi kwe-±0.05mm. Iqinisekisa ukugqitywa okugudileyo kokusila okuchanekileyo, ukubhola kunye nezinye iinkqubo, okungqina ngokupheleleyo amandla amahle kakhulu ezinto zegranite okugcina uzinzo lwesakhiwo phantsi komthwalo ophezulu.
Ukumelana nokunxiba ngexesha lokusebenza ixesha elide
Ukusebenza ixesha elide rhoqo kuthetha ukungqubana rhoqo phakathi kwezinto ezihambayo, nto leyo ebeka uvavanyo olukhulu ekuchaseni ukuguguleka kwezinto. Ubunzima begranite buphezulu, ubunzima beMohs buhlala buyi-6-7, xa kuthelekiswa nezinto ezininzi zesinyithi ezinganyamezeliyo ukuguguleka. Kwimveliso yokwenyani, njengeqonga le-XYZT leworkshop yokwenza isikhunta seemoto, iibhilethi ezinkulu zesikhunta kufuneka zenziwe ngomatshini ochanekileyo imihla ngemihla, kwaye iqonga lisebenza ukuya kuthi ga kwiiyure ezili-16 ngosuku. Emva kokujonga ukusetyenziswa ixesha elide, ukuguguleka komphezulu kwezinto zegranite kuncinci kakhulu, emva kweeyure ezili-10,000 zokusebenza okuqhubekayo, ukuguguleka komphezulu kwegranite xa idibana neendawo ezihambayo zeqonga kungama-0.02mm kuphela, kuphantsi kakhulu kunezixhobo zesinyithi eziqhelekileyo, okunciphisa ngempumelelo ukuhla kokuchaneka okubangelwa kukuguguleka kunye nokugcinwa kwezixhobo rhoqo, ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kweqonga.
Imeko yomda oncediswa kukuzinza kobushushu
Imveliso yobushushu yezixhobo ibalulekile ngexesha lokusebenza komthwalo ophezulu, kwaye utshintsho lobushushu luya kuchaphazela ngokulula ukusebenza kwecandelo. I-coefficient yokwandiswa kobushushu begranite iphantsi kakhulu, ngokubanzi kwi-5-7 × 10⁻⁶/℃, kwaye utshintsho lobungakanani luncinci phantsi kokuguquguquka okukhulu kobushushu. Kwinkqubo ye-photolithography yeshishini lokuvelisa iitshiphusi ze-elektroniki, iqonga lokuhamba kwe-gantry echanekileyo ye-XYZT kufuneka lithwale izixhobo ze-photolithography ezichanekileyo kakhulu ixesha elide, ezivelisa ubushushu obuninzi xa izixhobo zisebenza, kwaye ubushushu beworkshop bunokunyuka nge-5-10℃ ngexesha elifutshane. Kule meko, iqonga elixhaswa ziinxalenye zegranite lihlala lizinzile, ngaphandle kokuguquguquka okucacileyo kobushushu ngenxa yotshintsho lobushushu, liqinisekisa ukuchaneka kwe-chip lithography, lifezekisa ukusebenza okude kakhulu nokuzinzileyo kweeyure ezingama-20 ngosuku, liphula ixesha elimiselweyo lokusebenza kwamaqonga ezinto ezifanayo eziqhelekileyo, ligxininisa inzuzo yokuqina kweenxalenye zegranite kwiindawo ezixineneyo zobushushu.
