I. Inqubo Yokukhiqiza i-Granite Straightedge
Ukuhlolwa nokusikwa kwezinto ezingavuthiwe
Izindlela zokukhetha izinto: I-granite esezingeni eliphezulu enobukhulu obungu-≥2.7g/cm³ kanye nesilinganiso sokumuncwa kwamanzi esingu-<0.1% (njenge-"Jinan Green" evela eShandong kanye ne-"Black Gold Sand" evela eNdiya) kufanele kukhethwe. Izinhlayiya zamaminerali kufanele zifane (izinhlayiya ze-quartz ≤2mm), zingenamifantu nama-pores, futhi amatshe afihliwe kufanele asuswe ngokutholwa kwamaphutha e-X-ray.
Ukusika okuqinile: Sebenzisa isaha eliyindilinga ledayimane ukuze usike isikhala esingenalutho sibe isikhala esikhulu ngo-5-10mm kunosayizi womkhiqizo oqediwe. Iphutha lokuba yisicaba kwendawo yokusika kufanele lilawulwe ngaphakathi kuka-±0.5mm.
2. Ukwelashwa kokuguga
Ukuguga kwemvelo: Beka umzimba oluhlaza emoyeni ovulekile izinyanga ezingu-6 kuya kwezingu-12. Ngenxa yomehluko wokushisa phakathi kwemini nobusuku kanye nokushintsha komswakama, ukucindezeleka kwangaphakathi okungaphezu kuka-90% kuyakhishwa ukuze kuvinjelwe ukuguquka kwesimo sesikhumba kamuva.
Ukuguga kokwenziwa (ongakukhetha): Abanye abakhiqizi basebenzisa isithando sokushisa esingaguquki (100-150℃) amahora angama-24 ukusheshisa ukukhululwa kokucindezeleka, okufanelekela ama-oda aphuthumayo, kodwa umphumela uphansi kancane kunokuguga kwemvelo.
3. Ukugaya okuqinile kanye nokucubungula ubuso obubhekiselwe kukho
Ukugaya nokubumba okunzima: Sebenzisa isondo lokugaya ledayimane elinama-mesh angu-200-400 ukuze ugaye indawo engenalutho, ususe imigqa yokusika, ulungise ukuthamba kusuka ku-±0.5mm kuya ku-±0.1mm/m (100μm/m), bese unquma indawo ebhekisele kuyo.
Ukwelashwa kwendawo engasebenzi: Faka i-chamfer noma umboze izindawo eziseceleni naphansi (njengokufafaza upende ovimbela ukugqwala) ukuze uvimbele ukuqhekeka komphetho nokwanda kokumuncwa komswakama.
4. Ukugaya ngokunemba (inqubo eyinhloko)
Ukugxuma okunembile kufezwa ngokugaya ngokwezinga, okuhlukaniswe ngezigaba ezintathu:
Ukugaya okungekuhle: Sebenzisa ama-brasives angu-400-800 ane-mesh (i-silicon carbide noma i-diamond micro-powder) kuhlanganiswe nepulatifomu yokugaya ye-granite ukulungisa ukuthamba kube yi-±10μm/m, kanye nokungaguquguquki kobuso okungu-Ra≤0.8μm.
Ukugaya ngokunemba: Ngokushintshela ku-1200-2000 mesh abrasives nokuhlanganisa ne-elekthronikhi (ukunemba ±1μm/m) ukuze kuqashwe ngesikhathi sangempela, ukuthamba kuthuthukisiwe kwaba yi-±3μm/m, kanti ukugoba kobuso be-Ra kungu-≤0.4μm.
Ukugaya okucolekile kakhulu (isihluthulelo semikhiqizo enembile kakhulu): Ngokusebenzisa i-W10-W5 micro-powder (usayizi wezinhlayiya 5-10μm) kanye noketshezi lokupholisha ngamakhemikhali, ngesenzo esiphindwe kabili "sokugaya ngomshini + ukugqwala kwamakhemikhali", ukuthamba kokugcina kungafinyelela ku-±1μm/m, kanye nobukhulu bomphezulu Ra≤0.2μm.
5. Ukutholwa nokulungiswa okunembile
Imishini yokuthola: I-interferometer ye-laser (ukunemba ± 0.1μm) kanye nezinga le-elekthronikhi (isisombululo esingu-0.001mm/m) zisetshenziselwa ukuthola ububanzi obugcwele bokuthamba nokuqondile, kanye nokudweba imephu yokusatshalaliswa kwamaphutha.
Ukulungiswa kwe-Closed-loop: Ngokusekelwe kudatha yokuthola, ukugaya okwengeziwe kwendawo kwenziwa endaweni enamaphutha amaningi ngomshini wokugaya we-CNC kuze kube yilapho iphutha eliphelele lilawulwa ngaphakathi kobubanzi obuqondiwe.
6. Ukuvikelwa kobuso kanye nokupakishwa
Ukwelashwa okuvikelayo: Futha i-nano-scale silica coating (ubukhulu obungu-5-10μm) endaweni yokubhekisela, bese ufaka ungqimba lwe-wax olulwa nokugqwala endaweni engasebenzi ukuvimbela ukumuncwa komswakama noma i-oxidation ngesikhathi sokusetshenziswa isikhathi eside.
Ukupakisha okunembile: Kupakishwe emabhokisini okhuni angashaqeki anezinciphisi zokukhipha amanzi. Ngesikhathi sokuthuthwa, umehluko wokushisa ulawulwa ngaphakathi kuka-±5℃ ukuze kugwenywe ukuncishiswa kokunemba okubangelwa ukudlidliza.
Ii. Izinga Eliphakeme Kakhulu Lokunemba kanye Nezindinganiso Zemboni
Ukunemba kwe-granite straightedge kusekelwe ephutheni le-flatness njenge-core index. Ngokwezinga likazwelonke (GB/T 4977-2018) kanye nezinga lamazwe ngamazwe (ISO 2768-2), amazinga alo okunemba kanye nemingcele ehambisanayo yile:
Ama-laboratory aphezulu angafinyelela ukunemba okuphelele:
Ngokusebenzisa amasu okugaya ama-nano-scale (njengokupholisha kwe-magneorheological kanye nokuguqulwa kwe-ion beam), ukuba yisicaba kweminye imikhiqizo ephezulu kungahlukaniswa kube yi-±0.5μm/m (okungukuthi, iphutha ngobude bemitha alidluli ama-micrometer angu-0.5), kusondela ekubhekiseleni kwendiza ye-optical-grade. Zisetshenziswa kakhulu ezimweni ezinembile kakhulu njengezikhungo zezindiza kanye ne-metrology.
Iii. Ukuqhathaniswa Kwezici Ezithinta Ukunemba
Isifinyezo: Ukunemba okuphezulu kwe-granite straightedge kuncike ekulawulweni kwenqubo ephelele "kwezinto zokusetshenziswa ezisezingeni eliphezulu + ukuguga okude kakhulu + ukugaya okunezinga eliphezulu + indawo enzima", lapho inqubo yokugaya iyisisekelo sempumelelo ekuqondeni. Ngokuthuthuka kobuchwepheshe bokwenziwa kwe-nanofabrication, ukunemba kwayo kuqhubekela phambili kancane kancane ezingeni le-sub-micron futhi sekuyindlela yokulinganisa engenakuphikwa emkhakheni wokukhiqiza okuphezulu.
