Fasaha na aunawa don granite - daidai ga micron
Granite ya cika buƙatun fasahar aunawa na zamani a cikin injiniyoyi.Kwarewa a cikin kera benci na aunawa da gwadawa da daidaita injunan auna ya nuna cewa granite yana da fa'ida daban-daban akan kayan gargajiya.Dalili kuwa shine kamar haka.
Haɓaka fasahar aunawa a cikin 'yan shekarun nan da shekarun da suka gabata har yanzu yana da ban sha'awa a yau.A farkon, hanyoyin ma'auni masu sauƙi kamar allunan aunawa, auna benci, benches gwaji, da sauransu sun wadatar, amma bayan lokaci buƙatun ingancin samfur da amincin tsari ya zama mafi girma kuma mafi girma.Ana ƙayyade daidaiton ma'auni ta asali na lissafin lissafin da aka yi amfani da shi da rashin tabbas na binciken daban-daban.Koyaya, ayyukan aunawa suna zama masu rikitarwa da ƙarfi, kuma dole ne sakamakon ya zama daidai.Wannan yana ba da busharar wayewar yanayin daidaita yanayin sararin samaniya.
Daidaito yana nufin rage son zuciya
Na'ura mai daidaitawa ta 3D ta ƙunshi tsarin sakawa, babban tsarin aunawa, sauyawa ko na'urori masu aunawa, tsarin kimantawa da software na auna.Don cimma daidaiton ma'auni mai girma, dole ne a rage girman ma'aunin.
Kuskuren auna shine bambanci tsakanin ƙimar da kayan aunawa ke nunawa da ainihin ƙimar ma'auni na lissafin lissafi (ma'aunin daidaitawa).Kuskuren auna tsawon E0 na injunan daidaitawa na zamani (CMMs) shine 0.3+L/1000µm (L shine tsayin da aka auna).Zane na na'urar aunawa, bincike, dabarun aunawa, kayan aiki da mai amfani suna da tasiri mai mahimmanci akan karkacewar auna tsawon.Tsarin injina shine mafi kyawu kuma mafi ɗorewa abin tasiri.
Aiwatar da granite a cikin metrology yana ɗaya daga cikin mahimman abubuwan da ke shafar ƙirar injin aunawa.Granite kyakkyawan abu ne don buƙatun zamani saboda ya cika buƙatu huɗu waɗanda ke sa sakamakon ya zama daidai:
1. Babban kwanciyar hankali na asali
Granite dutse ne mai aman wuta wanda ya ƙunshi manyan abubuwa guda uku: quartz, feldspar da mica, wanda aka samo shi ta hanyar crystallization na dutsen yana narkewa a cikin ɓawon burodi.
Bayan dubban shekaru na "tsufa", granite yana da nau'i mai nau'i kuma babu damuwa na ciki.Misali, impalas sun kai kimanin shekaru miliyan 1.4.
Granite yana da babban taurin: 6 akan sikelin Mohs da 10 akan sikelin taurin.
2. High zafin jiki juriya
Idan aka kwatanta da kayan ƙarfe, granite yana da ƙaramin ƙima na faɗaɗawa (kimanin 5µm/m*K) da ƙaramin ƙarancin haɓakawa (misali karfe α = 12µm/m* K).
Ƙananan ƙarancin zafin jiki na granite (3 W / m * K) yana tabbatar da jinkirin mayar da martani ga canjin zafin jiki idan aka kwatanta da karfe (42-50 W / m * K).
3. Kyakkyawan tasirin raguwar girgiza
Saboda tsarin tsari, granite ba shi da ragowar damuwa.Wannan yana rage girgiza.
4. Dogon jagora mai daidaitawa guda uku tare da babban madaidaici
Granite, wanda aka yi da dutse mai wuyar halitta, ana amfani dashi azaman farantin aunawa kuma ana iya sarrafa shi da kyau tare da kayan aikin lu'u-lu'u, yana haifar da sassan injin tare da ainihin ainihin asali.
Ta hanyar niƙa da hannu, ana iya inganta daidaiton layin jagora zuwa matakin ƙananan micron.
Lokacin niƙa, ana iya la'akari da nakasar ɓangaren da ke dogaro da lodi.
Wannan yana haifar da matsa lamba sosai, yana ba da damar yin amfani da jagororin ɗaukar iska.Jagororin ɗaukar iska suna da inganci sosai saboda ingancin saman ƙasa da motsi mara lamba na shaft.
a ƙarshe:
Matsakaicin kwanciyar hankali, juriya na zafin jiki, damping vibration da daidaitaccen layin dogo sune manyan halaye guda huɗu waɗanda ke sa granite ya zama kyakkyawan abu don CMM.Ana ƙara amfani da Granite wajen kera benci na aunawa da gwadawa, da kuma akan CMMs don auna allo, teburin aunawa da kayan aunawa.Hakanan ana amfani da Granite a wasu masana'antu, kamar kayan aikin injin, injin laser da tsarin, injin micromachining, injin bugu, injunan gani, injin taro, sarrafa semiconductor, da dai sauransu, saboda karuwar madaidaicin buƙatun na injuna da kayan aikin injin.
