Ubuchwepheshe bokulinganisa i-granite - bunembile kuma-micron
I-Granite ihlangabezana nezidingo zobuchwepheshe bokulinganisa besimanje kwezobunjiniyela bemishini. Okuhlangenwe nakho ekukhiqizeni amabhentshi okulinganisa nokuhlola kanye nemishini yokulinganisa edidiyelwe kukhombisile ukuthi i-granite inezinzuzo ezihlukile kunezinto zendabuko. Isizathu simi kanje.
Ukuthuthukiswa kobuchwepheshe bokulinganisa eminyakeni yamuva namashumi eminyaka kusajabulisa nanamuhla. Ekuqaleni, izindlela zokulinganisa ezilula ezifana namabhodi okulinganisa, amabhentshi okulinganisa, amabhentshi okuhlola, njll. zazanele, kodwa ngokuhamba kwesikhathi izidingo zekhwalithi yomkhiqizo kanye nokuthembeka kwenqubo zanda kakhulu. Ukunemba kokulinganisa kunqunywa yi-geometry eyisisekelo yeshidi elisetshenzisiwe kanye nokungaqiniseki kokulinganisa kweprobe efanele. Kodwa-ke, imisebenzi yokulinganisa iya ngokuya iba yinkimbinkimbi futhi ishintshashintsha, futhi imiphumela kumele ibe nembe kakhudlwana. Lokhu kumemezela ukuqala kwe-spatial coordinate metrology.
Ukunemba kusho ukunciphisa ubandlululo
Umshini wokulinganisa we-3D coordinate uqukethe uhlelo lokubeka indawo, uhlelo lokulinganisa olunesinqumo esiphezulu, izinzwa zokushintsha noma zokulinganisa, uhlelo lokuhlola kanye nesofthiwe yokulinganisa. Ukuze kufezwe ukunemba kokulinganisa okuphezulu, ukuphambuka kokulinganisa kumele kuncishiswe.
Iphutha lokulinganisa umehluko phakathi kwenani eliboniswa yithuluzi lokulinganisa kanye nenani langempela lokubhekisela lobuningi bejometri (izinga lokulinganisa). Iphutha lokulinganisa ubude u-E0 wemishini yokulinganisa yesimanje (ama-CMM) ngu-0.3+L/1000µm (u-L ubude obulinganisiwe). Umklamo wedivayisi yokulinganisa, i-probe, isu lokulinganisa, umsebenzi kanye nomsebenzisi unethonya elikhulu ekuphambukeni kokulinganisa ubude. Umklamo wemishini uyinto ethonya kakhulu futhi eqhubekayo.
Ukusetshenziswa kwe-granite ku-metrology kungenye yezinto ezibalulekile ezithinta ukwakheka kwemishini yokulinganisa. I-granite iyinto enhle kakhulu yezidingo zesimanje ngoba igcwalisa izidingo ezine ezenza imiphumela ibe nembe kakhudlwana:
1. Ukuqina okuphezulu okungokwemvelo
I-Granite yidwala lentaba-mlilo elakhiwe yizingxenye ezintathu eziyinhloko: i-quartz, i-feldspar kanye ne-mica, elakhiwe yi-crystallization yokuncibilika kwedwala oqweqweni.
Ngemva kweminyaka eyizinkulungwane “yokuguga”, i-granite inokwakheka okufanayo futhi ayinayo ingcindezi yangaphakathi. Isibonelo, ama-impala aneminyaka engaba yizigidi ezingu-1.4 ubudala.
I-granite inobulukhuni obukhulu: 6 esikalini se-Mohs kanye no-10 esikalini sobulukhuni.
2. Ukumelana nokushisa okuphezulu
Uma kuqhathaniswa nezinto zensimbi, i-granite ine-coefficient ephansi yokwanda (cishe i-5µm/m*K) kanye nesilinganiso sokwanda esiphansi (isb. insimbi α = 12µm/m*K).
Ukushisa okuphansi kwe-granite (3 W/m*K) kuqinisekisa ukusabela okuhamba kancane ekushintsheni kwezinga lokushisa uma kuqhathaniswa nensimbi (42-50 W/m*K).
3. Umphumela omuhle kakhulu wokunciphisa ukudlidliza
Ngenxa yesakhiwo esifanayo, i-granite ayinayo ingcindezi eseleyo. Lokhu kunciphisa ukudlidliza.
4. Isitimela sokuqondisa esinezixhumanisi ezintathu ngokunemba okuphezulu
I-granite, eyenziwe ngamatshe aqinile emvelo, isetshenziswa njengepuleti lokulinganisa futhi ingashintshwa kahle ngamathuluzi edayimane, okuholela ezingxenyeni zomshini ngokunemba okuphezulu okuyisisekelo.
Ngokugaya ngesandla, ukunemba kwemizila yokuqondisa kungathuthukiswa kuze kufike ezingeni le-micron.
Ngesikhathi sokugaya, ukuguquguquka kwezingxenye okuncike emthwalweni kungacatshangelwa.
Lokhu kuphumela endaweni ecindezelwe kakhulu, okuvumela ukusetshenziswa kweziqondiso zokuthwala umoya. Iziqondiso zokuthwala umoya zinembile kakhulu ngenxa yekhwalithi ephezulu yendawo kanye nokunyakaza komgodi okungathintani.
Ekuphetheni:
Ukuqina okungokwemvelo, ukumelana nokushisa, ukudambisa ukudlidliza kanye nokunemba kwereyili yokuqondisa yizici ezine ezinkulu ezenza i-granite ibe yinto efanelekile ye-CMM. I-Granite isetshenziswa kakhulu ekwakhiweni kwamabhentshi okulinganisa nokuhlola, kanye naku-CMMs yamabhodi okulinganisa, amatafula okulinganisa kanye nemishini yokulinganisa. I-Granite isetshenziswa nakwezinye izimboni, njengamathuluzi omshini, imishini ye-laser kanye nezinhlelo, imishini ye-micromachining, imishini yokunyathelisa, imishini ye-optical, ukuzenzekela kokuhlanganiswa, ukucubungula kwe-semiconductor, njll., ngenxa yezidingo zokunemba ezikhulayo zemishini nezingxenye zomshini.
