Emkhakheni wokulawula ukunyakaza okunembile kakhulu, ukusebenza kwemodyuli yokunyakaza okunembile kakhulu emoyeni kuncike kakhulu ezicini zesisekelo sayo. Isisekelo sokunemba kwe-granite kanye nesisekelo se-ceramic njengezinketho ezimbili eziphezulu, ngayinye inezinzuzo ezihlukile, ekuzinzeni, ekugcinweni kokunemba, ukuqina kanye nezinye izilinganiso ezibalulekile kunomehluko osobala.
Ukuzinza: ukuqina kwemvelo uma kuqhathaniswa nokunemba okwenziwe
I-granite yakhiwe ngemva kwesikhathi eside se-geological, isakhiwo sangaphakathi siminyene futhi sifana, futhi amaminerali afana ne-quartz ne-feldspar axhumene kakhulu. Uma ibhekene nokuphazamiseka kwangaphandle, njengokudlidliza okubangelwa ukusebenza kwemishini emikhulu eshabhu, isisekelo se-granite singavimba futhi sinciphise ngempumelelo ngesakhiwo saso esiyinkimbinkimbi sekristalu, okunganciphisa ubukhulu bokudlidliza kwemodyuli yokunyakaza eqondile kakhulu edluliselwa emoyeni ontantayo ngaphezu kuka-80%, okuhlinzeka ngesisekelo sokusebenza esizinzile semodyuli ukuqinisekisa ukuthi ihamba kahle enkambisweni yokucubungula noma ukuthola okunembile kakhulu.
Isisekelo se-ceramic sakhiwe ngenqubo yokwenziwa ethuthukisiwe, futhi ukufana kwaso kwangaphakathi nakho kuhle kakhulu. Isakhiwo esincane sezinye izinto ze-ceramic ezisebenza kahle cishe siphelele, esingakha umphumela wokudambisa ophumelelayo ekudlidlizeni. Kweminye imishini yokuhlola okubonakalayo ezwela kakhulu ekudlidlizeni, isisekelo se-ceramic singacindezela ukuphazamiseka kokudlidliza ebangeni elincane kakhulu ukuqinisekisa ukunyakaza okunembile kakhulu kwemodyuli yokunyakaza eqondile kakhulu ye-air float, kodwa ngenxa yokudlidliza okukhulu nokuqina okuphezulu, ukuzinza kwayo okuphelele kuphansi kancane kunokwesisekelo se-granite.
Ukugcinwa kokunemba: inzuzo yemvelo yokwanda okuphansi kanye nesimangaliso sokwenziwa sokuqina kokushisa okuphezulu
I-Granite yaziwa ngokulingana kwayo okuphansi kakhulu kokukhula kokushisa, ngokuvamile ku-5-7 × 10⁻⁶/℃. Endaweni yokuguquguquka kwezinga lokushisa, usayizi wesisekelo sokunemba kwe-granite awushintshi kakhulu. Isibonelo, emkhakheni wezinkanyezi, imodyuli yokunyakaza enembile kakhulu yokulungiswa kahle kwelensi yethelesikopu ihambisana nesisekelo se-granite, ngisho nasendaweni lapho umehluko wokushisa phakathi kwemini nobusuku ubalulekile, ingaqinisekisa ukuthi ukunemba kokubekwa kwelensi kugcinwa ezingeni le-sub-micron, kusize izazi zezinkanyezi ukuthi zibambe izinguquko ezicashile zezinto zasezulwini ezikude.
Izinto zobumba zisebenza kahle ekuzinzeni kwezinga lokushisa eliphezulu kanye nezici zokukhula eziphansi, futhi i-coefficient yokwanda kokushisa kwezinye izinto zobumba ezikhethekile ingaba phansi kakhulu cishe ku-zero. Ngaphansi kwesimo sokushisa okuphezulu noma ushintsho olusheshayo lokushisa, isisekelo sobumba singagcina usayizi ozinzile ukuqinisekisa ukuthi ukunemba kokunyakaza kwemoduli yokunyakaza enembile kakhulu ye-air float ayithinteki. Enqubweni ye-lithography yokukhiqizwa kwama-chip e-semiconductor, imishini ye-lithography idinga ukuqhubeka nokusebenza endaweni enembile kakhulu, futhi isisekelo sobumba singagcina ukunemba kokubekwa kwemoduli endaweni eshisayo ephezulu ekhiqizwe yimishini, ihlangabezana nezidingo eziqinile zokukhiqiza ama-chip ukuze kube nokunemba kwe-nanoscale.
Ukuqina: Ukuqina okuphezulu kwe-ore yemvelo kanye nezinto zokwenziwa ezingamelani nokugqwala
Ubulukhuni begranite buphezulu, ubulukhuni be-Mohs bungafinyelela ku-6-7, ngokumelana okuhle nokuguguleka. Elabhorethri yesayensi yezinto zokwakha, imodyuli yokunyakaza evame ukusetshenziswa kakhulu yokuntanta emoyeni, isisekelo sayo segranite singamelana ngempumelelo nokungqubuzana kwesikhathi eside kwesilayida sokuntanta emoyeni, uma kuqhathaniswa nesisekelo sezinto ezivamile, singandisa umjikelezo wokugcinwa kwemodyuli ngaphezu kuka-50%, kunciphisa kakhulu izindleko zokugcinwa kwemishini, ukuqinisekisa ukuqhubeka komsebenzi wocwaningo lwesayensi.
Izinto zobumba azigcini nje ngokuba nobunzima obukhulu, kodwa futhi zinokumelana nokugqwala okuhle kakhulu. Kwezinye izindawo zezimboni lapho kunengozi yokugqwala kwamakhemikhali, njengemoduli yokunyakaza enembile kakhulu yokuntanta komoya emishinini yokuhlola umkhiqizo wamakhemikhali, isisekelo sobumba singamelana nokuguguleka kwamagesi noma uketshezi olugqwalisayo, sigcine ubuqotho bomphezulu kanye nezakhiwo zemishini isikhathi eside, futhi ukuqina kwaso kungcono kunesisekelo se-granite ezindaweni ezithile ezinzima.
Izindleko zokukhiqiza kanye nobunzima bokucubungula: izinselele zokumba nokucubungula itshe lemvelo kanye nomkhawulo wobuchwepheshe wokwenziwa kokwenziwa
Inqubo yokumba nokuthutha izinto zokusetshenziswa ze-granite iyinkimbinkimbi, futhi ukucubungula kudinga imishini nobuchwepheshe obuphezulu kakhulu. Ngenxa yobunzima bayo obukhulu kanye nokuqhekeka, kulula ukuba nezinkinga ezifana nokuwa komphetho kanye nokuqhekeka ekusikeni, ekugayeni, ekupholisheni nakwezinye izinqubo, futhi izinga lokulahla izinto ezilahliwe liphezulu kakhulu, okuholela ezindleleni zokukhiqiza eziphezulu.
Ukukhiqizwa kwezisekelo ze-ceramic kuncike ekuhlanganisweni okuthuthukisiwe kanye nobuchwepheshe bokukhanda ngokunemba, kusukela ekulungisweni kwezinto zokusetshenziswa, ukubumba kuya ekushiseni, isinyathelo ngasinye sidinga ukulawulwa okuqondile. Ukutshalwa kwezimali kwasekuqaleni ekuthuthukisweni nasekukhiqizweni kwezisekelo ze-ceramic ezisebenza kahle kukhulu futhi umkhawulo wobuchwepheshe uphakeme, kodwa uma sekufezwe ukukhiqizwa okukhulu, izindleko kulindeleke ukuthi zilawulwe ngempumelelo, futhi zinamandla okusebenzisa imali kahle ezinhlelweni zokusebenza eziphezulu.
Sekukonke, izisekelo zokunemba kwe-granite zisebenza kahle ekuzinzeni okuphelele nasekuqineni okuvamile, kuyilapho izisekelo ze-ceramic zinezinzuzo ezihlukile ekuzivumelaniseni nezimo zemvelo ezishisa kakhulu kanye nokuqina kokumelana nokugqwala. Ukukhetha isisekelo kufanele kusekelwe esimweni esithile sokusetshenziswa, izimo zemvelo kanye nesabelomali sezindleko semojuli yokunyakaza ye-air float ultra-precision motion.
