Izindinganiso zokuhlola izingxenye zokunemba kwe-granite
Izinga lokunemba elilinganiselwe
Ngokwemigomo efanele yemboni, ukubekezelelana okubalulekile kwezingxenye zokunemba kwe-granite kudingeka kulawulwe ngaphakathi kobubanzi obuncane kakhulu. Uma sithatha ipulatifomu yokulinganisa i-granite evamile njengesibonelo, ukubekezelelana kwayo ubude nobubanzi kuphakathi kuka-±0.05mm no-±0.2mm, futhi inani elithile lincike kusayizi wengxenye kanye nezidingo zokunemba zesimo sesicelo. Isibonelo, epulatifomu yokugaya ilensi ye-optical enemba kakhulu, ukubekezelelana okulinganayo kungalawulwa ku-±0.05mm, kuyilapho ukubekezelelana okulinganayo kwepulatifomu yokuhlola imishini ejwayelekile kungakhululeka ku-±0.2mm. Ngobukhulu bangaphakathi obufana nokuvuleka nobubanzi besikhala, ukunemba kokubekezelela nakho kuqinile, njengomgodi wokufaka esisekelweni se-granite osetshenziselwa ukufaka inzwa yokunemba, ukubekezelelana kokuvuleka kufanele kulawulwe ku-±0.02mm ukuqinisekisa ukunemba nokuzinza kokufakwa kwenzwa.
Izinga lokuthamba
Ukuthamba kuyinkomba ebalulekile yezingxenye zokunemba kwegranite. Ngokwezinga likazwelonke/izinga laseJalimane, ukubekezelelana kokuthamba kwamazinga ahlukene okunemba kweplatifomu yegranite kuchazwe ngokucacile. Ukubekezelelana kokuthamba kweplatifomu yekilasi 000 kubalwa njengo-1×(1 + d/1000)μm (d ubude obuqondile, iyunithi mm), 2×(1 + d/1000)μm yekilasi 00, 4×(1 + d/1000)μm yekilasi 0, kanye no-8×(1 + d/1000)μm yekilasi 1. Isibonelo, iplatifomu yegranite yekilasi 00 enobubanzi obungu-1000mm inokubekezelelana kokuthamba okungu-2×(1 + 1000/1000)μm = 4μm. Ezisetshenzisweni ezisebenzayo, njengeplatifomu ye-lithography enqubweni yokukhiqiza ama-chip kagesi, ngokuvamile kudingeka ukuthi kuhlangatshezwane nezinga lokuthamba elingu-000 noma elingu-00 ukuqinisekisa ukunemba kwendlela yokusabalala kokukhanya enqubweni ye-chip lithography futhi kugwenywe ukuphambuka kwephethini ye-chip okubangelwa yiphutha lokuthamba kweplatifomu.
Izinga lokuqina kobuso
Ubulukhuni bomphezulu bezingxenye zokunemba kwe-granite buthinta ngqo ukunemba nokusebenza okufana nezinye izingxenye. Ngaphansi kwezimo ezivamile, ubulukhuni bomphezulu i-Ra yesikhulumi se-granite esisetshenziselwa izingxenye ze-optical kufanele ifinyelele ku-0.1μm-0.4μm ukuqinisekisa ukuthi izingxenye ze-optical zingagcina ukusebenza okuhle kwe-optical ngemuva kokufakwa futhi zinciphise ukusabalala kokukhanya okubangelwa izindawo ezingalingani. Kwipulatifomu evamile ye-granite esetshenziselwa ukuhlolwa komshini, ubulukhuni bomphezulu i-Ra bungakhululwa bube ngu-0.8μm-1.6μm. Ubulukhuni bomphezulu buvame ukutholakala ngokusebenzisa imishini yobungcweti efana ne-profiler, enquma ukuthi inani lobulukhuni bomphezulu liyahlangabezana yini nezindinganiso ngokulinganisa isilinganiso sokuphambuka kwesilinganiso sephrofayili ye-microscopic yomphezulu.
Izindinganiso zokuthola amaphutha angaphakathi
Ukuze kuqinisekiswe ikhwalithi yangaphakathi yezingxenye ezinembile ze-granite, kuyadingeka ukuthola ngokuqinile amaphutha azo angaphakathi. Uma usebenzisa ukuhlolwa kwe-ultrasonic, ngokwezindinganiso ezifanele, lapho kutholakala ukuthi kunezimbobo, imifantu kanye nezinye iziphambeko ezingaphezu kosayizi othile (njengobubanzi obukhulu kuno-2mm), ingxenye ibhekwa njengengafaneleki. Ekuhlolweni kwe-X-ray, uma isithombe se-X-ray sibonisa amaphutha angaphakathi aqhubekayo athinta amandla esakhiwo sengxenye, njengeziphambeko eziqondile ezinobude obungaphezu kuka-10mm noma amaphutha amakhulu anendawo engaphezu kuka-50mm², ingxenye nayo ayihlangabezani nezindinganiso zekhwalithi. Ngokusebenzisa ngokuqinile lezi zindinganiso, ingagwema ngempumelelo izinkinga ezinkulu njengokuphuka kwezingxenye okubangelwa amaphutha angaphakathi ngesikhathi sokusetshenziswa, futhi iqinisekise ukuphepha kokusebenza kwemishini kanye nokuqina kwekhwalithi yomkhiqizo.
Ukwakhiwa kwesisombululo sokuhlola izimboni
Ukuhlanganiswa kwemishini yokulinganisa ngokunemba okuphezulu
Ukuze kunqotshwe inkinga yokutholakala kwengxenye ye-granite ngokunemba, kubalulekile ukwethula imishini yokulinganisa ethuthukisiwe. I-interferometer ye-laser inokunemba okuphezulu kakhulu ngobude kanye nokulinganisa i-Engela, futhi ingalinganisa ngokunembile ubukhulu obubalulekile bezingxenye ze-granite, futhi ukunemba kwayo kokulinganisa kungafinyelela kuma-nanometer, okungahlangabezana ngempumelelo nezidingo zokutholwa kokubekezelelana okunembe kakhulu. Ngesikhathi esifanayo, izinga le-elekthronikhi lingasetshenziswa ukukala ngokushesha nangokunembile ukuthamba kwezingxenye ze-granite zepulatifomu, ngokulinganisa kwamaphuzu amaningi futhi kuhlanganiswe nama-algorithms ochwepheshe, kungadweba iphrofayili yokuthamba enembile, ukunemba kokutholwa kufikela ku-0.001mm/m. Ngaphezu kwalokho, isithwebuli se-3D optical singaskena ngokushesha ubuso obuyinkimbinkimbi bengxenye ye-granite ukuze sikhiqize imodeli ephelele enezinhlangothi ezintathu, engathola ngokunembile ukuphambuka kwesimo ngokuqhathanisa nemodeli yokuklama, inikeze ukwesekwa kwedatha okuphelele kokuhlolwa kwekhwalithi yomkhiqizo.
Ukusetshenziswa kobuchwepheshe bokuhlola obungabhubhisi
Ngenxa yosongo olungase lube khona lokukhubazeka kwe-granite yangaphakathi ekusebenzeni kwezingxenye, ukuhlolwa okungabhubhisi kubalulekile. I-Ultrasonic flaw detector ingakhipha i-ultrasound ephindaphindayo, lapho igagasi lomsindo lihlangana nemifantu, izimbobo kanye nezinye izinkinga ngaphakathi kwe-granite, izobonakalisa futhi isakazeke, ngokuhlaziya isignali yamagagasi ebonakalisiwe, ingahlulela ngokunembile indawo, usayizi kanye nesimo sesici. Ukuze kutholakale amaphutha amancane, ubuchwepheshe bokuthola amaphutha e-X-ray bunenzuzo enkulu, bungangena ezintweni ze-granite ukuze bakhe isithombe sesakhiwo sangaphakathi, bubonise ngokucacile amaphutha amancane okunzima ukuwabona ngamehlo enyama, ukuqinisekisa ukuthi ikhwalithi yangaphakathi yesici ithembekile.
Uhlelo lwesofthiwe yokuthola ehlakaniphile
Uhlelo lwesofthiwe yokuthola oluhlakaniphile olunamandla luyisizinda esiyinhloko sesisombululo sonke. Uhlelo lungafingqa, luhlaziye futhi lucubungule idatha eqoqwe yizo zonke izinhlobo zemishini yokuhlola ngesikhathi sangempela. Ngokusebenzisa ama-algorithms obuhlakani bokwenziwa, isofthiwe ingakhomba ngokuzenzakalelayo izici zedatha futhi inqume ukuthi izingxenye ze-granite ziyahlangabezana yini nezindinganiso zekhwalithi, ithuthukise kakhulu ukusebenza kahle kokuthola kanye nokunemba. Isibonelo, ngokuqeqesha inani elikhulu ledatha yokuhlola ngamamodeli okufunda okujulile, isofthiwe ingakhomba ngokushesha nangokunembile uhlobo kanye nobunzima beziphambeko zobuso, igweme ukwahlulela okungaba khona okubangelwa ukuhumusha ngesandla. Ngesikhathi esifanayo, uhlelo lwesofthiwe lungakhiqiza nombiko wokuhlola onemininingwane, lurekhode idatha yokuhlola kanye nemiphumela yengxenye ngayinye, okulula ngamabhizinisi ukwenza ukulandelelwa kwekhwalithi nokuphathwa.
Izinzuzo ze-ZHHIMG ezixazululweni zokuhlola
Njengomholi embonini, i-ZHHIMG iqoqe ulwazi olucebile emkhakheni wokuhlolwa kwezingxenye ze-granite ngokunemba. Le nkampani inethimba lochwepheshe le-R & D, elihlala lizibophezele ekusunguleni nasekuthuthukiseni ubuchwepheshe bokuhlola, ngokuya ngezidingo ezikhethekile zezixazululo zokuhlola ezenziwe ngokwezifiso zamakhasimende. I-ZHHIMG yethule imishini yokuhlola ethuthukisiwe yamazwe ngamazwe futhi yasungula uhlelo lokulawula ikhwalithi oluqinile ukuqinisekisa ukuthi ukuhlolwa ngakunye kungafinyelela ezingeni eliphezulu embonini. Ngokuphathelene nezinsizakalo, inkampani inikeza izinsizakalo zokuma okukodwa kusukela ekwakhiweni kohlelo lokuhlola, ukufakwa kwemishini kanye nokuqaliswa kwayo kuya ekuqeqeshweni kwabasebenzi ukuqinisekisa ukuthi amakhasimende angazisebenzisa kahle izixazululo zokuhlola futhi athuthukise amakhono okulawula ikhwalithi yomkhiqizo.
