Juyin Juya Hali a Duban Injin Injin Ruwa: Yadda Ake Cimma Ma'aunin Ma'auni Mai Girma Uku na 0.1μ M akan Platforms Granite?

Daidaiton injunan injin aero yana da alaƙa da aikin injin gabaɗaya, kuma ma'aunin kwane-kwane mai girma uku a matakin 0.1μm ya zama ainihin abin da ake buƙata na masana'anta. Dandalin al'ada yana da wuyar cika ka'idodi. Dandalin Granite, tare da manyan fa'idodi guda uku, suna ba da ingantaccen tallafi don gano ainihin ganowa.

Zaman lafiyar zafi yana gina madaidaicin tushe. Matsakaicin haɓakar haɓakar thermal na granite shine kawai (4-8) × 10⁻⁶ / ℃, wanda ya fi 60% ƙasa da na ƙarfe. A ƙarƙashin canjin yanayin zafin jiki na ± 1 ℃, girman canjin dandali mai tsayin mita 1 bai wuce 0.008μm ba, wanda zai iya ba da madaidaicin shimfidar wuri don kayan aiki irin su interferometers na laser da injunan aunawa guda uku, guje wa tarin kurakuran auna lalacewa ta hanyar nakasar thermal. A halin yanzu, yawan sa ya kai 2.6-2.8g/cm³, ƙarfinsa na matsawa ya wuce 200MPa, yana da juriya, kuma yana tabbatar da cewa daidaito ya kasance baya canzawa akan amfani na dogon lokaci.

Fitaccen juriya na jijjiga da keɓewar tsangwama ga muhalli. Taron bitar jiragen sama yana girgiza akai-akai. Tsarin kristal na musamman na granite ya sa rabonsa ya kai 0.05-0.1, wanda shine sau 5-10 na karafa. Yana iya rage fiye da 90% na kuzarin girgiza cikin daƙiƙa 0.3. Ɗaukar ma'auni tare da laser tracker a matsayin misali, lokacin da aka haɗa shi da dandamali na granite, ana iya sarrafa ma'auni na laser a cikin ± 0.02μm, yana inganta ma'auni daidaitattun kurakuran bayanin martaba.

Haɗe-haɗe na ƙwararrun ƙwararrun ƙwararru da hankali suna haɓaka inganci. Bayan matsananci-daidaici aiki kamar magnetorheological polishing, da flatness na granite dandali ya kai ± 0.1μm/m, da surface roughness Ra ne ≤0.02μm. Bayan an haɗa shi tare da masu mulki na nanoscale grating da AI algorithms, daidaitattun ma'auni guda ɗaya ya kai 0.05μm, an rage kuskuren gabaɗaya zuwa ± 0.1μm, ƙimar ganowa ta karu da 30%, kuma ƙimar gano lahani ya kai 99.9%.

Matakan dandali na Granite, tare da kwanciyar hankali da ingantaccen aikin su, suna kiyaye madaidaicin ma'aunin injin iska, haɓaka haɓaka daidaiton masana'antar jirgin sama, da kuma taimakawa masana'antar ta kai sabon matsayi.
