Granite straightedge "chiyero chisingaoneki" chekuona kuti zvinhu zvakagadzirwa nemidziyo yemakanika zvakarurama. Zvinhu zvakakosha zvinokanganisa kugadzikana kwemidziyo yese yekugadzira uye mwero wekukodzera chigadzirwa, izvo zvinonyanya kuratidzwa muzvikamu zvinotevera:
"Kusatsiviwa" kwechirevo chakarurama
Kuiswa nekuiswa kwenzira dzekushandisa maturusi emuchina nematafura ekushanda mumutsara wekugadzira kunofanirwa kuenderana nekutwasuka (≤0.01mm/m) uye parallelism (≤0.02mm/m) yegranite straightedge. Zvinhu zvayo zvechisikigo zvine density yakakura (3.1g/cm³) zvinogona kuchengetedza kutwasuka kwenguva yakareba, ne thermal expansion coefficient ye1.5×10⁻⁶/℃ chete. Kunyangwe musiyano wetembiricha uri mukuru sei muworkshop, hazvizokonzere kuti reference ichinje nekuda kwe "thermal expansion and contraction" - uku "kugadzikana" uko simbi ruler dzisingakwanise kuita, kudzivirira zvakananga zvikanganiso zvekuunganidza michina zvinokonzerwa nereferensi dzisina kururama.
2. "Mutambo weKugara Kwenguva Refu" weKudzivirira Kudedera uye Kusapfeka
Nzvimbo yekugadzira zvinhu yakaoma, uye zvakajairika kuti zvinhu zvinotonhodza uye zvidimbu zvesimbi zvipararire. Kuomarara kwakanyanya kwegranite (ine kuomarara kweMohs kwe6-7) kunoita kuti isakwenye uye haizokanganiswi kana kukuvadzwa nezvidimbu zvesimbi seruler yesimbi yakakandwa. Panguva imwe chete, ine simba rakasimba rekunyungudutsa vibration. Panguva yekuyera, inogona kuderedza kukanganiswa kwevibration kunokonzerwa nekushanda kwechishandiso chemuchina, zvichiita kuti kuverenga kwevernier caliper uye dial indicator kuve kwakasimba uye kudzivirira kutsauka kwekuyera kunokonzerwa nekusakara kwezvishandiso.
"lexile Adaptation" yezviitiko
Mitsetse yakasiyana yekugadzira ine zvinodiwa zvakasiyana zvehurefu uye giredhi rerure rakarurama:
Kune mitsetse midiki yekugadzira zvikamu, sarudza rure rakagadzirwa ne0-grade rine dhayamita ye500-1000mm, iro rakareruka uye rinosangana nezvinodiwa nemazvo.
Mitsetse yekubatanidza maturusi emuchina inorema inoda marula akatwasuka ane 2000-3000mm 00-grade. Dhizaini yenzvimbo inoshanda kaviri inobvumira kuenzaniswa panguva imwe chete kwenzira dzekutungamira dzekumusoro nedzepasi.
4. "Kukosha Kwakavanzika" Kwekudzora Mari
Rura regranite remhando yepamusoro rinogona kugara kwemakore anopfuura gumi, izvo zvinodhura zvishoma kwenguva refu kupfuura rura resimbi (nekutsiva kwemakore matatu kusvika mashanu). Chinonyanya kukosha ndechekuti rinogona kuderedza nguva yekugadzirisa michina kuburikidza nekuongororwa kwakanyatsojeka. Imwe fekitori yezvishandiso zvemota yakashuma kuti mushure mekushandisa rura regranite, kushanda zvakanaka kwekuchinja kwemhando yekugadzira uye kugadzirisa kwakawedzera ne40%, uye mwero wezvimedu zvakadonha kubva pa3% kusvika pa0.5%. Iyi ndiyo kiyi ye "kuchengetedza mari nekuvandudza kushanda zvakanaka".
Pamitsetse yekugadzira, marula egranite haasi maturusi ekuyera ari nyore chete asi "magedhi ekuyera akarurama". Kusarudza akakodzera kunoita kuti mutsetse wese uve nechivimbo. Iwo maturusi ekuyera granite akakosha pamitsetse yekugadzira nemazvo yeindasitiri.
