Emkhakheni wokulawula ukunyakaza okunembe kakhulu, ukusebenza kwemojuli yokunyakaza ye-air float ultra-precision motion kuncike kakhulu kuzici zesisekelo sayo. Isisekelo se-granite sokunemba kanye nesisekelo se-ceramic njengezinketho ezimbili eziphezulu, ngayinye inezinzuzo eziyingqayizivele, ekuzinzeni, ukugcinwa kokunemba, ukuqina kanye nezinye izilinganiso ezibalulekile kukhona umehluko osobala.
Ukuzinza: ukubumbana kwemvelo ngokumelene nokunemba kokwenziwa
I-Granite eyakhiwe ngemva kwesikhathi eside se-geological, isakhiwo sangaphakathi siminyene futhi sifana, futhi amaminerali afana ne-quartz ne-feldspar ahlanganiswe eduze. Lapho ubhekene nokuphazamiseka kwangaphandle, njengokudlidliza okubangelwa ukusebenza kwemishini emikhulu ku-workshop, isisekelo se-granite singavimba ngokuphumelelayo futhi sinciphise isakhiwo saso sekristalu esiyinkimbinkimbi, esinganciphisa i-vibration amplitude ye-ultra-precision motion module edluliselwa emoyeni ngaphezu kwe-80%, inikeze isisekelo esiqinile sokusebenza ukuze kuqinisekiswe ukutholakala kwamamojula ngokushelelayo.
Isisekelo se-ceramic sikhiqizwa ngenqubo yokwenziwa ethuthukisiwe, futhi ukufana kwaso kwangaphakathi kwesakhiwo nakho kuhle kakhulu. I-microstructure yezinye izinto ze-ceramic ezisebenza kahle zicishe ziphelele, ezingakha umthelela osebenzayo wokudambisa ukudlidliza. Kwezinye izinto zokuhlola ezibonakalayo ezizwela kakhulu ukudlidliza, isisekelo se-ceramic singacindezela ukuphazamiseka kokudlidliza ebangeni elincane kakhulu ukuze kuqinisekiswe ukunyakaza okunembe okuphezulu kwemojula yokunyakaza yokunemba kwe-ultra-precision yokuntanta komoya, kodwa ngokusabela ekudlidlizeni okukhulu nokunamandla aphezulu, ukuzinza kwayo konke kungaphansi kancane kokwesisekelo segwadle.
Ukugcinwa kokunemba: inzuzo yemvelo yokwanda okuphansi kanye nesimangaliso sokwenziwa sokuqina kwezinga lokushisa eliphezulu
I-Granite yaziwa nge-coefficient yayo ephansi kakhulu yokunwetshwa kokushisa, ngokuvamile ku-5-7 × 10⁻⁶/℃. Esimweni sokushintshashintsha kwezinga lokushisa, usayizi wesisekelo sokunemba se-granite ushintsha kancane kakhulu. Isibonelo, emkhakheni wesayensi yezinkanyezi, imojula yokunyakaza okunembe kakhulu yokucushwa kahle kwelensi yesibonakude ibhangqwe nesisekelo segwadle, ngisho nasendaweni lapho umehluko wezinga lokushisa phakathi kwemini nobusuku ubalulekile, ingaqinisekisa ukuthi ukunemba kokuma kwelensi kugcinwa ezingeni le-sub-micron, kusize izazi zezinkanyezi ukuthi zithwebule izinguquko ze-substitle.
Izinto zobumba nazo zenza kahle ekuzinzeni kwezinga lokushisa eliphezulu nasezicini zokunwetshwa eziphansi, futhi i-coefficient yokwanda okushisayo kwezinye izitsha zobumba ezikhethekile zingase zibe phansi ngokusondela ku-zero. Ngaphansi kwesimo sokushisa okuphezulu noma ukushintsha kwezinga lokushisa okusheshayo, isisekelo se-ceramic singagcina usayizi ozinzile ukuze kuqinisekiswe ukuthi ukunemba kokunyakaza kwe-ultra-precision motion module of the air float ayithinteki. Enqubweni ye-lithography yokwenziwa kwe-semiconductor chip, imishini ye-lithography idinga ukuqhubeka nokusebenza endaweni enembayo ephezulu, futhi isisekelo se-ceramic singagcina ukunemba kokuma kwemojula endaweni yokushisa ephezulu ekhiqizwe imishini, ehlangabezana nezidingo eziqinile zokwenziwa kwe-chip ngokunemba kwe-nanoscale.
Ukuqina: Ukuqina okuphezulu kwama-ore emvelo nezinto zokwenziwa ezimelana nokugqwala
Ubulukhuni be-Granite buphezulu, ubulukhuni be-Mohs bungafinyelela ku-6-7, ngokumelana okuhle kokugqoka. Elabhorethri yesayensi yezinto ezibonakalayo, imojula yokunyakaza yomoya evame ukusetshenziswa kakhulu, isisekelo sayo segwadle singamelana ngokuphumelelayo nokungqubuzana kwesikhathi eside kwesilayidi se-air float, uma kuqhathaniswa nesisekelo sezinto ezivamile, singanweba umjikelezo wokugcinwa kwemojula ngaphezu kuka-50%, kwehlise kakhulu izindleko zokugcinwa kwemishini, ukuze kuqinisekiswe ukuqhubeka komsebenzi wocwaningo lwesayensi.
Izinto ze-Ceramic azigcini nje ngokuba nobunzima obuphezulu, kodwa futhi zinokumelana nokugqwala okuhle kakhulu. Kwezinye izindawo zezimboni lapho kunobungozi bokugqwala kwamakhemikhali, njengemojula yokunyakaza okunembe kakhulu yokuntanta komoya emishinini yokuhlola umkhiqizo wamakhemikhali, isisekelo se-ceramic singamelana nokuguguleka kwamagesi agqwalayo noma uketshezi, sigcine ubuqotho obungaphezulu kanye nezakhiwo zemishini isikhathi eside, futhi ukuqina kwayo kungcono kunesisekelo segwadle ezindaweni ezithile ezinokhahlo.
Izindleko zokukhiqiza kanye nobunzima bokucubungula: izinselelo zezimayini nokucubungula kwetshe lemvelo kanye nomkhawulo wezobuchwepheshe wokuhlanganisa okwenziwayo
Inqubo yezimayini kanye nokuthutha ye-granite yezinto zokusetshenziswa iyinkimbinkimbi, futhi ukucubungula kudinga imishini nobuchwepheshe obuphezulu kakhulu. Ngenxa yokuqina kwayo okuphezulu nokuqina kwayo, kulula ukuba nezinkinga njengokuwa konqenqema kanye nokuqhekeka kokusika, ukugaya, ukupholisha nezinye izinqubo, futhi izinga le-scrap liphezulu kakhulu, okuholela ezindlekweni eziphezulu zokukhiqiza.
Ukwakhiwa kwezisekelo ze-ceramic kuncike ekuhlanganiseni okuthuthukile kanye nobuchwepheshe bokunemba bemishini, kusukela ekulungiseleleni impahla eluhlaza, ukubumba kuya ekushiseni, isinyathelo ngasinye sidinga ukulawulwa okunembile. Ukutshalwa kwezimali kwangaphambi kwesikhathi ekuthuthukisweni nasekukhiqizweni kwezisekelo ze-ceramic ezisebenza kahle kukhulu futhi umkhawulo wezobuchwepheshe uphakeme, kodwa uma usufinyelele ukukhiqizwa okukhulu, izindleko kulindeleke ukuthi zilawulwe ngokuphumelelayo, futhi zinamandla angabizi kakhulu ekusetshenzisweni okuphezulu.
Sekukonke, izisekelo ze-granite ezinembayo zisebenza kahle ekuzinzeni okuphelele nokuqina okuvamile, kuyilapho izisekelo ze-ceramic zinezinzuzo ezihlukile ekuguquguqukeni kwendawo yokushisa okwedlulele kanye nokuqina kokumelana nokugqwala. Ukukhethwa kwesisekelo kufanele kusekelwe esimeni esithile sohlelo lokusebenza, izimo zemvelo kanye nesabelomali sezindleko zemojula yokunyakaza ye-air float ultra-precision motion.
