Granite da Karfe da Siminti: Kwatancen Kayan Aiki
Kwanciyar Hankali ta Zafi
Ɗaya daga cikin muhimman abubuwan da ke haifar da yanayin metrology shine faɗaɗa yanayin zafi. Ko da ƙananan canjin yanayin zafi na iya haifar da canje-canje masu ma'ana.
- Granite: Yana nuna kusan sifili siffa ta faɗaɗa granite a ƙarƙashin yanayin da aka sarrafa. Matsakaicin faɗaɗa zafi (CTE) ɗinsa ya yi ƙasa sosai kuma ya fi daidaito idan aka kwatanta da ƙarfe. Bugu da ƙari, tsarin isotropic na granite yana tabbatar da daidaiton ɗabi'a a kowane bangare.
- Karfe: Yana da babban CTE (~11–13 µm/m·°C), wanda hakan ke sa shi ya zama mai matuƙar saurin kamuwa da canje-canjen yanayin zafi. Saurin yanayin zafi na iya haifar da karkacewa da damuwa ta ciki.

Ilimin Lissafi Da Ke Bayan Fifikon Granite
Amfanin dutse yana da tushe a cikin kaddarorin jiki da na kayansa:
- Tsarin lu'ulu'u
Granite ya ƙunshi ƙwayoyin ma'adinai masu haɗaka (musamman quartz, feldspar, da mica). Wannan tsari yana kawo cikas ga yaɗuwar raƙuman injina, yana ƙara danshi. - Ƙarancin kwararar zafi
Granite yana zafi da sanyaya a hankali, yana rage yanayin zafi da tasirin faɗaɗawa na gida. - Babban Mass da Tauri
Yawan duwatsun yana taimakawa wajen samar da tushe mai ƙarfi, mai ƙarfi wanda ke tsayayya da matsalolin waje. - Halayyar Isotropic
Ba kamar ƙarfe da ke iya nuna halayen shugabanci ba saboda birgima ko siminti, granite yana aiki iri ɗaya a cikin dukkan gatari, yana tabbatar da aiki mai faɗi.
Tasiri kan Daidaiton Ma'auni
Haɗakar tasirin kwanciyar hankali na zafi da damƙar girgiza kai tsaye yana fassara zuwa:
- Rage rashin tabbas na ma'auni
- Ingantaccen maimaituwa da sake haifuwa

Ga injiniyoyin da ke tsara tsarin CMM mai inganci, waɗannan abubuwan ba wai kawai suna da amfani ba ne—suna da mahimmanci.
Me yasa Granite shine Matsayin Masana'antu
Amfani da tushen dutse don tsarin CMM ba wani zaɓi bane na musamman, amma matsayin masana'antu don daidaiton tsarin aunawa. Yayin da juriyar masana'antu ke ƙaruwa kuma buƙatun inganci ke ƙaruwa, buƙatar kayan tushe masu ƙarfi da ƙarfi suna ci gaba da ƙaruwa.
