I. Inqubo Yokukhiqiza yeGranite Straightedge
Ukuhlolwa kwezinto ezingavuthiwe kanye nokusika
Imibandela yokukhetha okokusebenza: Igwadle yekhwalithi ephezulu enesisindo esingu-≥2.7g/cm³ kanye nezinga lokumunca amanzi elingu-< 0.1% (elifana ne-"Jinan Green" evela e-Shandong kanye "Ne-Black Gold Sand" yase-India) kufanele kukhethwe. Izinhlayiya zamaminerali kufanele zifane (izinhlayiya ze-quartz ≤2mm), zingabi nemifantu nezimbotshana, futhi amatshe anesici afihliwe kufanele asuswe ngokutholwa kwamaphutha e-X-ray.
Ukusika okungalungile: Sebenzisa isaha eliyindilinga ledayimane ukuze usike okungenalutho kube into engenalutho engu-5-10mm enkulu kunosayizi womkhiqizo oqediwe. Iphutha le-flatness lendawo yokusika kufanele ilawulwe ngaphakathi kuka-± 0.5mm.
2. Ukwelashwa kokuguga
Ukuguga kwemvelo: Beka umzimba oluhlaza endaweni evulekile izinyanga eziyisi-6 kuya kweziyi-12. Ngomehluko wezinga lokushisa phakathi kwemini nobusuku kanye nezinguquko zomswakama, ngaphezu kwama-90% wengcindezi yangaphakathi kukhululwa ukuvimbela ukuwohloka esikhathini esizayo.
Ukuguga okwenziwayo (ongakukhetha) : Abanye abakhiqizi basebenzisa isithando somlilo esingaguquki (100-150℃) amahora angu-24 ukuze kusheshiswe ukukhululwa kwengcindezi, okufanele ama-oda aphuthumayo, kodwa umphumela ungaphansi kancane kunowokuguga kwemvelo.
3. Ukugaya okungalungile kanye nokucubungula indawo yereferensi
Ukugaya nokwakheka okuqinile: Sebenzisa isondo lokugaya idayimane elinenetha elingu-200-400 ukuze ugaye okungenalutho, ukhiphe imigqa yokusika, ulungise ukucaba ukusuka ku-±0.5mm ukuya ku-±0.1mm/m (100μm/m), futhi unqume indawo yereferensi.
Ukwelashwa kwendawo engasebenzi: I-Chamfer noma gcoba izindawo eziseceleni nezingaphansi (njengokufafaza ngopende ovimbela ukugqwala) ukuze uvimbele ukuqhekeka konqenqema kanye nokunwetshwa kokumuncwa komswakama.
4. Ukugaya okunembayo (inqubo ewumgogodla)
Ukweqa okunembayo kufinyelelwa ngokugaya kwe-hierarchical, okuhlukaniswe izigaba ezintathu:
Ukugaya kanzima: Sebenzisa ama-abrasives angu-400-800 anezikhala (i-silicon carbide noma i-diamond micro-powder) kuhlanganiswe neplathifomu yokugaya igwadle ukuze ulungise ukucaba kube ±10μm/m, kanye nobulukhuni obungaphezulu obungu-Ra≤0.8μm.
Ukugaya okunembayo: Ngokushintshela kuma-abrasives anezikhala angu-1200-2000 futhi ahlanganiswe nezinga le-elekthronikhi (ukunemba okungu-±1μm/m) ukuze kuqashwe isikhathi sangempela, ukucaba kuthuthukisiwe kwaba ngu-±3μm/m, kanti ubulukhuni bendawo u-Ra ngu-≤0.4μm.
Ukugaya okucolisekileyo (ukhiye wemikhiqizo enembayo ephezulu) : Ngokusebenzisa i-W10-W5 grade micro-powder (usayizi wezinhlayiyana 5-10μm) kanye noketshezi lokupholisha ngamakhemikhali, ngesenzo esikabili "sokugaya ngomshini + ukugqwala kwamakhemikhali", ukugqwala kokugcina kungafinyelela ku-±1μm/m, kanye nobulukhuni obuphezulu obungu-Ra≤0.2μm.
5. Ukutholwa okunembile nokulungiswa
Imishini yokuhlonza: I-laser interferometer (ukunemba okungu-±0.1μm) kanye neleveli kagesi (ukulungiswa okungu-0.001mm/m) kusetshenziselwa ukutholwa kobubanzi obugcwele bokucaba nokuqondile, kanye nokudweba imephu yokusabalalisa iphutha.
Ukulungiswa kweluphu evaliwe: Ngokusekelwe kudatha yokuthola, ukugaya okungeziwe kwendawo kwenziwa endaweni enephutha elikhulu ngomshini wokugaya we-CNC kuze kube yilapho iphutha losayizi ogcwele lilawulwa ngaphakathi kwebanga eliqondiwe.
6. Ukuvikelwa kobuso nokupakishwa
Ukwelashwa kokuvikela: Fafaza ungqimba lwe-silica esikalini se-nano (ugqinsi oluyi-5-10μm) endaweni yereferensi, bese usebenzisa ungqimba lwe-wax elwa nokugqwala endaweni engasebenzi ukuze uvimbele ukumuncwa komswakama noma ukukhipha i-oxidation ngesikhathi sokusetshenziswa isikhathi eside.
Ukupakishwa okunembayo: Ipakishwe emakesini okhuni angangenwa ukushaqeka anama-desiccants. Ngesikhathi sokuthutha, umehluko wezinga lokushisa ulawulwa phakathi kuka-±5℃ ukugwema ukuncishiswa okunembayo okubangelwa ukudlidliza.
Ii. Ibanga Lokunemba Okuphakeme Namazinga Omkhakha
Ukunemba kwe-granite straightedge kusekelwe ephutheni le-flatness njengenkomba eyinhloko. Ngokwendinganiso kazwelonke (GB/T 4977-2018) kanye nezinga lamazwe ngamazwe (ISO 2768-2), amabanga ayo okunemba kanye nemingcele ehambisanayo imi kanje:
Amalabhorethri aphezulu angafinyelela ukunemba okuphelele:
Ngokusebenzisa izindlela zokugaya ze-nano-scale (ezifana nokupholishwa kwe-magneorheological kanye nokuguqulwa kwe-ion beam), ukucaba kweminye imikhiqizo ephezulu kunganqanyulwa kufinyelele ku-±0.5μm/m (okungukuthi, iphutha ngemitha ngalinye aleqi ama-micrometer angu-0.5), kusondela ireferensi yendiza yebanga lokubona. Asetshenziswa kakhulu ezimeni ezinembe ngokwedlulele njenge-aerospace kanye nezikhungo ze-metrology.
Iii. Ukuqhathaniswa Kwezinto Ezithinta Ukunemba
Isifinyezo: Ukunemba okuphezulu kwe-granite straightedge kuncike ekulawuleni inqubo egcwele "yezinto zokusetshenziswa zekhwalithi ephezulu + ukuguga okunezinga eliphakeme + lendawo yokugaya + enokhahlo", lapho inqubo yokugaya iwumgogodla wokuphumelela ngokunemba. Ngokuthuthukiswa kobuchwepheshe be-nanofabrication, ukunemba kwayo kancane kancane kuqhubekela phambili kuzinga le-sub-micron futhi sekuphenduke ithuluzi lokuma elingenakushintshwa emkhakheni wokukhiqiza okuphezulu.
