Ubuchwepheshe bokulinganisa be-granite - bunembile ku-micron
I-Granite ihlangabezana nezidingo zobuchwepheshe besimanje bokulinganisa kubunjiniyela bemishini.Isipiliyoni ekwenziweni kwamabhentshi okulinganisa nawokuhlola kanye nemishini yokulinganisa yokuxhumanisa kubonise ukuthi igwadle linezinzuzo ezihlukile kuzinto 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. zazenele, kodwa ngokuhamba kwesikhathi izidingo zekhwalithi yomkhiqizo nokuthembeka kwenqubo zaba phezulu naphezulu.Ukunemba kwesilinganiso kunqunywa i-geometry eyisisekelo yeshidi elisetshenzisiwe kanye nokungaqiniseki kokulinganisa kwe-probe efanele.Kodwa-ke, imisebenzi yokulinganisa iba inkimbinkimbi futhi ishintshashintsha, futhi imiphumela kufanele icace kakhudlwana.Lokhu kumemezela ukuqala kwe-spatial coordinate metrology.
Ukunemba kusho ukunciphisa ukuchema
Umshini wokulinganisa we-3D we-coordinate uqukethe isistimu yokumisa, isistimu yokulinganisa ukucaca okuphezulu, izinzwa zokushintsha noma zokulinganisa, isistimu yokuhlola kanye nesofthiwe yokulinganisa.Ukuze kuzuzwe ukunemba kwesilinganiso esiphezulu, ukuchezuka kokulinganisa kufanele kuncishiswe.
Iphutha lokulinganisa umehluko phakathi kwevelu eboniswa ithuluzi lokulinganisa kanye nenani langempela eliyireferensi lobuningi bejiyomethri (izinga lokulinganisa).Iphutha lesilinganiso sobude u-E0 wemishini yokulinganisa yesimanje yokudidiyela (CMMs) ngu-0.3+L/1000µm (L ubude obulinganisiwe).Idizayini yedivayisi yokulinganisa, i-probe, isu lokulinganisa, ucezu lokusebenza nomsebenzisi kunomthelela omkhulu ekuchezukeni kwesilinganiso sobude.Idizayini yemishini iyisici esinomthelela esihle kakhulu nesimeme kakhulu.
Ukusetshenziswa kwegwadle ku-metrology kungenye yezinto ezibalulekile ezithinta ukwakheka kwemishini yokulinganisa.I-Granite iyinto enhle kakhulu yezidingo zesimanje ngoba ifeza izimfuneko ezine ezenza imiphumela inembe kakhulu:
1. Ukuzinza okuphezulu okungokwemvelo
I-Granite iyidwala lentaba-mlilo elakhiwe izingxenye ezintathu eziyinhloko: i-quartz, i-feldspar ne-mica, eyakhiwe ngokucwebezela kwetshe elincibilikayo kuqweqwe.
Ngemuva kwezinkulungwane zeminyaka "yokuguga", i-granite inokuthungwa okufanayo futhi akukho ukucindezeleka kwangaphakathi.Ngokwesibonelo, ama-impala aneminyaka engaba yizigidi ezingu-1.4 ubudala.
I-Granite inobunzima obukhulu: 6 esikalini se-Mohs no-10 esikalini sokuqina.
2. Ukumelana nokushisa okuphezulu
Uma kuqhathaniswa nezinto ezisansimbi, igwadle line-coefficient ephansi yokunweba (cishe. 5µm/m*K) kanye nezinga lokunweba eliphelele eliphelele (isb. insimbi α = 12µm/m*K).
I-thermal conductivity ephansi ye-granite (3 W/m*K) iqinisekisa ukusabela okunensayo ekuguquguqukeni kwezinga lokushisa uma kuqhathaniswa nensimbi (42-50 W/m*K).
3. Umphumela omuhle kakhulu wokunciphisa ukudlidliza
Ngenxa yesakhiwo esifanayo, i-granite ayinakho ukucindezeleka okusele.Lokhu kunciphisa ukudlidliza.
4. Isitimela esineziqondiso ezintathu esinembe kakhulu
I-Granite, eyenziwe ngetshe eliqinile lemvelo, isetshenziswa njengepuleti yokulinganisa futhi ingenziwa kahle kakhulu ngamathuluzi edayimane, okuholela ezingxenyeni zomshini ezinokunemba okuphezulu okuyisisekelo.
Ngokugaya okwenziwa ngesandla, ukunemba kwama-rails omhlahlandlela kungathuthukiswa kuze kufike ezingeni le-micron.
Ngesikhathi sokugaya, ukuguqulwa kwengxenye encike kumthwalo kungacatshangelwa.
Lokhu kubangela indawo ecindezelwe kakhulu, okuvumela ukusetshenziswa kweziqondiso ezithwala umoya.Iziqondiso ezithwala umoya zinembe kakhulu ngenxa yekhwalithi ephezulu yendawo kanye nokunyakaza okungathinteki kwe-shaft.
Ekuphetheni:
Ukuzinza okungokwemvelo, ukumelana nezinga lokushisa, ukuncibilika kokudlidliza kanye nokunemba kukajantshi oqondisayo yizici ezine ezinkulu ezenza igwadle libe into efanelekile ye-CMM.I-Granite isetshenziswa ngokwandayo ekwenzeni amabhentshi okulinganisa nawokuhlola, kanye nama-CMM kumabhodi okulinganisa, amatafula okulinganisa kanye nemishini yokukala.I-Granite iphinde isetshenziswe kwezinye izimboni, njengamathuluzi omshini, imishini ye-laser nezinhlelo, imishini ye-micromachining, imishini yokunyathelisa, imishini yokubona, i-automation ye-assembly, i-semiconductor processing, njll., ngenxa yezidingo zokunemba ezikhulayo zemishini nezingxenye zomshini.
