Kwilabhoratri echanekileyo yokuvelisa iitshiphusi, kukho iqhawe elibonakala lingenakulinganiswa "ngemva kwe-scenes hero" - isiseko somatshini wegranite. Ungalijongeli phantsi eli litye. Isitshixo sokuqinisekisa ukuchaneka kovavanyo olungonakalisi lweewafers! Namhlanje, makhe sijonge indlela egcina ngayo izixhobo zokubona rhoqo "zithe tye kwaye zithe nkqo".
1. Uzelwe "nemfuza ezinzileyo"
Igranite ayilolitye eliqhelekileyo. Ubume bayo bangaphakathi bufana ne "mineral jigsaw puzzle" evalwe ngokungqongqo. I-quartz, i-feldspar kunye nezinye iikristale zicwangciswe ngokusondeleyo, ezinoxinano oluphezulu kakhulu kwaye phantse akukho voids. Oku kufana nokwakha indlu ngekonkile eyomeleleyo, eyomeleleyo kwaye izinzile. Xa izixhobo zokuhlola "zihleli" kuyo, nokuba zinobunzima beetoni ezininzi, ukuguqulwa kwesiseko segranite akunanto, kuphela isahlulo seshumi sentsimbi!
Okumangalisa ngakumbi kukuba phantse ayiloyiki utshintsho lobushushu. Izinto eziqhelekileyo zentsimbi zikholisa "ukwandisa kwaye zityebe" xa zishushu kwaye "zikhontrakthi kwaye zibe zincinci" xa zipholile. Nangona kunjalo, i-granite ibonakala ngathi "inobushushu obuqhelekileyo bomlingo". Xa iqondo lobushushu liguquguquka nge-1℃, ukwanda kunye nokucutheka kwayo sisinye kwiwaka leenwele zomntu. Kufuneka kuqatshelwe ukuba nangona kukho utshintsho oluncinci kwiqondo lokushisa lebhubhoratri yokuvavanya, isiseko segranite sinokuxhasa ngokuqinileyo izixhobo kunye nokuthintela umgangatho "ukuphambuka".
Okwesibini, indlela yokucubungula "iinkcukacha zomtyholi"
Ukwenza isiseko segranite sichaneke ngakumbi, iinjineli zasebenzisa "itekhnoloji emnyama" yokucubungula. Khawufane ucinge amatye okupolisha nge "super sandpaper" eyenziwe ngedayimane - yile ndlela umatshini wokusila we-axis emihlanu usebenza ngayo. Iya kusila umphezulu wegranite ube mcaba kunesipili ngamanyathelo amathathu:
Ukusila ngokurhabaxa: Okokuqala, susa amabala angaphezulu elitye kwaye ulawule ukuba tyaba ukuya kumashumi amabini eenwele zomntu.
Ukusila ngokulinganayo: Ukucokiswa ngakumbi, ngokunyuka okuthe tyaba ukuya kwisinye kwishumi elinesihlanu leenwele zomntu.
Ukusila okucokisekileyo: Okokugqibela, kugudiswe ngomgubo wokusila ocolekileyo kakhulu, uphumeza umcaba wewaka leenwele zomntu! Ngeli xesha, umphezulu wesiseko segranite ufana "nenqanaba elithe tye" elenzelwe izixhobo zokuhlola.
Ezinye iindawo eziphakamileyo eziphezulu zine "ngqondo ehlakaniphile" - inqanaba elakhelwe ngaphakathi elichanekileyo lifana "nomlindi omncinci" osebenza iiyure ezingama-24 ngosuku. Nje ukuba ibone ukuba isixhobo sithambethekile ngamadigri angama-0.01 (i-Angle encinci kunencam yosiba), isixhobo soxinzelelo lomoya siya kuqalisa ukusebenza kwaye "solule" isixhobo kwimizuzwana engama-30.
Okwesithathu, uyilo oluchubekileyo lomeleza ngakumbi uzinzo
Iinjineli zikwagqogqa iingqondo zabo kubume bomatshini. Umzantsi wenziwa ukwakheka kwekhekheba lobusi elinamacala amathandathu, kanye njengesisele seenyosi, esingapheleli nje ekunciphiseni ubunzima kodwa sisasaze ngokulinganayo uxinezeleko. Xa i-probe yokufumanisa ihamba kwi-wafer, i-deformation kwindawo nganye yesiseko iphantse ifane, iqinisekisa ukuba isalathisi esithe tye sihlala sizinzile ngamaxesha onke.
Okumangalisa ngakumbi kukuba "i-absorber engabonakaliyo engabonakaliyo" - i-piezoelectric ceramic shock absorber - ifakwe phakathi kwesiseko kunye nomhlaba. Inokuthi ibambe iintshukumo ezahlukeneyo ukusuka kwi-1 ukuya kwi-1000Hz njengerada kwaye ngoko nangoko ikhuphe amaza angasemva ukuze "ichase" uphazamiseko. Umzekelo, ukungcangcazela okuveliswa kukusebenza koomatshini abasecaleni okanye ukushukuma kwezithuthi ezidlula ngaphandle konke "akunamsebenzi" phambi kwayo.
Idatha iyathetha ngokwayo: Unamandla kangakanani umphumo?
Kwizicelo ezibonakalayo, ukusebenza kwesiseko segranite kuyamangalisa ngokwenene:
Ukuhlolwa kwe-Optical: Ukuchaneka kokuchonga iziphene zomhlaba kwi-wafers kuye kwaphuculwa ukusuka kwi-3 microns ukuya kwi-1 micron (i-1 micron = ishumi elinesithandathu leenwele zomntu).
Uvavanyo lwe-Ultrasonic: Impazamo ekulinganiseni ubukhulu be-wafer ithotywe ngeekota ezintathu.
Ukusetyenziswa kwexesha elide: Emva kokusebenza ngokuqhubekayo unyaka, utshintsho kwinqanaba liphantse lingabalulekanga, ngelixa iziseko zoomatshini eziqhelekileyo sele zide "zizingela".
Ukusuka kwizibonelelo zezixhobo zendalo ukuya ekuqhubeni ngokuchanekileyo kunye noyilo oluyilwayo, isiseko segranite sibonakalise "ngamandla" ayo ukuba ufuna ukubona ngokuchanekileyo iitshiphusi, eli litye liyimfuneko ngokwenene!
