Fasahar aunawa don granite - daidai ga micron
Granite ya cika buƙatun fasahar aunawa ta zamani a fannin injiniyan injiniya. Kwarewa a fannin kera benci da gwaji da na'urorin aunawa masu daidaitawa ya nuna cewa granite yana da fa'idodi daban-daban fiye da kayan gargajiya. Dalilin haka shine kamar haka.
Ci gaban fasahar aunawa a cikin 'yan shekarun nan da shekarun da suka gabata har yanzu yana da ban sha'awa a yau. A farko, hanyoyin aunawa masu sauƙi kamar allunan aunawa, benci masu aunawa, benci masu gwaji, da sauransu sun isa, amma akan lokaci buƙatun ingancin samfura da amincin tsari sun ƙaru. Daidaiton aunawa ana tantance shi ta hanyar yanayin asali na takardar da aka yi amfani da ita da rashin tabbas na ma'auni na binciken da ya dace. Duk da haka, ayyukan aunawa suna ƙara zama masu rikitarwa da ƙarfi, kuma sakamakon dole ne ya zama daidai. Wannan yana nuna farkon tsarin daidaita sararin samaniya.
Daidaito yana nufin rage son zuciya
Injin auna daidaiton 3D ya ƙunshi tsarin sanyawa, tsarin aunawa mai ƙuduri mai girma, na'urori masu auna sauyawa ko aunawa, tsarin kimantawa da manhajar aunawa. Domin cimma daidaiton aunawa mai girma, dole ne a rage karkacewar aunawa.
Kuskuren aunawa shine bambanci tsakanin ƙimar da kayan aikin aunawa suka nuna da ainihin ƙimar ma'aunin lissafi (ma'aunin daidaitawa). Kuskuren auna tsayi E0 na injunan aunawa na zamani (CMMs) shine 0.3+L/1000µm (L shine tsawon da aka auna). Tsarin na'urar aunawa, bincike, dabarun aunawa, kayan aiki da mai amfani yana da tasiri mai mahimmanci akan karkacewar auna tsayi. Tsarin injina shine mafi kyawun kuma mafi dorewa.
Amfani da dutse a fannin nazarin halittu yana ɗaya daga cikin muhimman abubuwan da ke shafar ƙirar injunan aunawa. Granite abu ne mai kyau ga buƙatun zamani domin yana cika buƙatu guda huɗu waɗanda ke sa sakamakon ya zama daidai:
1. Babban kwanciyar hankali na ciki
Granite dutse ne mai aman wuta wanda ya ƙunshi manyan abubuwa guda uku: quartz, feldspar da mica, wanda aka samar ta hanyar lulluɓewar duwatsu a cikin ɓawon.
Bayan dubban shekaru na "tsufa", granite yana da tsari iri ɗaya kuma babu damuwa a ciki. Misali, impalas suna da shekaru kimanin miliyan 1.4.
Granite yana da tauri mai girma: 6 akan sikelin Mohs da 10 akan sikelin tauri.
2. Juriyar zafin jiki mai yawa
Idan aka kwatanta da kayan ƙarfe, granite yana da ƙarancin ma'aunin faɗaɗawa (kimanin 5µm/m*K) da kuma ƙarancin ƙimar faɗaɗawa gaba ɗaya (misali ƙarfe α = 12µm/m*K).
Ƙarancin ƙarfin wutar lantarki na granite (3 W/m*K) yana tabbatar da jinkirin amsawa ga canjin yanayin zafi idan aka kwatanta da ƙarfe (42-50 W/m*K).
3. Tasirin rage girgiza mai kyau sosai
Saboda tsarinsa iri ɗaya, granite ba shi da wani damuwa da ya rage. Wannan yana rage girgiza.
4. Layin jagora mai daidaitawa uku tare da babban daidaito
Ana amfani da dutse mai tauri na halitta a matsayin farantin aunawa kuma ana iya sarrafa shi da kayan aikin lu'u-lu'u sosai, wanda ke haifar da sassan injina masu inganci.
Ta hanyar niƙa da hannu, daidaiton layukan jagora za a iya inganta shi zuwa matakin micron.
A lokacin niƙa, ana iya la'akari da nakasar sassa masu dogaro da kaya.
Wannan yana haifar da saman da aka matse sosai, wanda ke ba da damar amfani da jagororin ɗaukar iska. Jagororin ɗaukar iska suna da daidaito sosai saboda ingancin saman da kuma motsi mara taɓawa na shaft.
a ƙarshe:
Kwanciyar hankali, juriya ga zafin jiki, damƙar girgiza da kuma daidaiton layin jagora sune manyan halaye guda huɗu da suka sanya granite ya zama abu mafi dacewa ga CMM. Ana ƙara amfani da granite wajen ƙera benci na aunawa da gwaji, da kuma akan CMMs don allunan aunawa, tebura na aunawa da kayan aikin aunawa. Haka kuma ana amfani da granite a wasu masana'antu, kamar kayan aikin injina, injunan laser da tsarin, injunan injina na micro, injunan bugawa, injunan gani, sarrafa kai ta atomatik, sarrafa semiconductor, da sauransu, saboda ƙaruwar buƙatun daidaito ga injuna da kayan aikin injina.
