Ya kamata barbashi ma'adinai su kasance iri ɗaya (barbashin quartz ≤2mm), ba tare da fashewa ba da pores, kuma a cire duwatsun da ke ɓoye ta hanyar gano lahani na X-ray.
Yanke m: Yi amfani da ma'aunin madauwari na lu'u-lu'u don yanke babur zuwa cikin sarari wanda ya fi 5-10mm girma fiye da girman samfurin da aka gama. Ya kamata a sarrafa kuskuren flatness na yanki a cikin ± 0.5mm.
2. Maganin tsufa
Tsufa ta dabi'a: Sanya jikin kore a cikin sararin sama tsawon watanni 6 zuwa 12. Ta hanyar bambancin zafin jiki tsakanin dare da rana da canje-canje a cikin zafi, sama da 90% na damuwa na ciki an saki don hana nakasawa a mataki na gaba.
Artificial tsufa (na zaɓi): Wasu masana'antun suna amfani da tanderun zafin jiki akai-akai (100-150 ℃) na tsawon sa'o'i 24 don haɓaka sakin damuwa, wanda ya dace da umarni na gaggawa, amma tasirin yana ɗan ƙasa da na tsufa na halitta.
3. M nika da tunani surface aiki
M nika da siffata: Yi amfani da 200-400 raga lu'u-lu'u dabaran nika lu'u-lu'u dabaran niƙa blank, cire yankan Lines, gyara flatness daga ± 0.5mm zuwa ± 0.1mm / m (100μm / m), da kuma ƙayyade tunani surface.
Maganin saman da ba sa aiki: Chamfer ko sutura a gefe da saman saman ƙasa (kamar feshin fenti mai tsatsa) don hana ɓarna gefen da faɗaɗa ɗanshi.
4. Madaidaicin niƙa (tsari mai mahimmanci)
Ana samun madaidaicin tsalle ta hanyar niƙa mai matsayi, wanda ya kasu kashi uku:
M nika: Yi amfani da 400-800 raga abrasives (silicon carbide ko lu'u-lu'u micro-foda) a hade tare da wani dutse nika dandali don gyara flatness zuwa ± 10μm/m, da kuma surface roughness Ra≤0.8μm.
Daidaitaccen niƙa: Ta hanyar canzawa zuwa 1200-2000 raga abrasives da haɗuwa tare da matakin lantarki (daidaitaccen ± 1μm / m) don saka idanu na lokaci-lokaci, an inganta kwanciyar hankali zuwa ± 3μm / m, kuma raƙuman ƙasa Ra shine ≤0.4μm.
Ultra-lafiya nika (maɓalli zuwa high-daidaici kayayyakin): By ta yin amfani da W10-W5 sa micro-foda (barbashi size 5-10μm) da kuma sinadaran polishing ruwa, ta hanyar dual mataki na "mechanical nika + sinadaran lalata", karshe flatness iya isa ± 1μm / m, da kuma surface roughness Ram.0.2μ.
5. Daidaitaccen ganowa da gyarawa
Kayan aiki na ganowa: Ana amfani da interferometer laser (daidaitaccen ± 0.1μm) da matakin lantarki (ƙuduri 0.001mm/m) don gudanar da cikakken gano lebur da madaidaiciya, da zana taswirar rarraba kuskure.
Gyaran madauki: Dangane da bayanan ganowa, ana yin ƙarin niƙa na gida akan babban yanki mai kuskure ta hanyar injin niƙa CNC har sai an sarrafa cikakken girman kuskure a cikin kewayon manufa.
6. Kariyar saman da marufi
Maganin kariya: Fesa murfin silica na nano-sikelin (kauri 5-10μm) akan farfajiyar tunani, kuma a yi amfani da wani Layer na kakin zuma mai hana lalata a saman da ba ya aiki don hana ɗaukar danshi ko oxidation yayin amfani na dogon lokaci.
Marufi madaidaici: An cushe shi a cikin akwati na katako da ba za a iya girgizawa tare da na'urar wankewa ba. A lokacin sufuri, ana sarrafa bambancin zafin jiki a cikin ± 5 ℃ don kauce wa madaidaicin attenuation lalacewa ta hanyar girgiza.
Ii. Madaidaicin Matsayi mafi Girma da Matsayin Masana'antu
Daidaiton madaidaicin granite yana dogara ne akan kuskuren flatness azaman maƙasudin mahimmanci. Dangane da ma'auni na ƙasa (GB/T 4977-2018) da ma'auni na duniya (ISO 2768-2), daidaiton makinsa da sigogi masu dacewa sune kamar haka:
Manyan dakunan gwaje-gwaje na iya cimma daidaito na ƙarshe:
Ta hanyar dabarun niƙa nano-sikelin (kamar magneorheological polishing da ion katako gyara), da flatness na wasu high-karshen kayayyakin za a iya karya ta hanyar zuwa ± 0.5μm/m (watau kuskure a kowace mita tsawon bai wuce 0.5 micrometers), gabatowa da Tantancewar-sa jirgin tunani. Ana amfani da su musamman a cikin madaidaitan yanayin yanayi kamar sararin samaniya da cibiyoyin awoyi.
Iii. Kwatanta Abubuwan Da Suka Shafi Daidaitawa
Takaitawa: Babban madaidaicin madaidaicin granite ya dogara da cikakken tsarin sarrafawa na "manyan kayan inganci masu inganci + tsufa mai tsayi + graded nika + yanayi mai tsauri", wanda tsarin niƙa shine tushen ci gaba a daidai. Tare da haɓaka fasahar nanofabrication, daidaitaccen sa a hankali yana ci gaba zuwa matakin ƙananan ƙananan micron kuma ya zama kayan aiki mai mahimmanci wanda ba za a iya maye gurbinsa ba a fagen masana'anta na ƙarshe.
