Granite Surface Plate Yakarurama Sei? .

Granite pamusoro mahwendefa ndiwo chaiwo maturusi anoshandiswa zvakanyanya mu metrology, kuongorora, uye machining application. Iwo akagadzirwa kubva kumhando yepamusoro yegranite yechisikigo, inokosheswa nekugadzikana kwayo, kusimba, uye flatness. Asi mahwendefa aya akarurama zvakadini? .
Natural Stability
Granite inoumbwa pamusoro pemamiriyoni emakore pasi pekumanikidzwa kwakanyanya uye kupisa, zvichiita kuti pave ne dense, yakanaka-grained chimiro. Uku kugadzikana kwechisikigo kunoita kuti granite ive chinhu chakanakira mahwendefa epamusoro, sezvo ichiramba deformation kubva mukushanduka kwekushisa, hunyoro, uye kushushikana kwemagetsi. Muchokwadi, granite ine yakaderera coefficient yekuwedzera kwekupisa, zvichireva kuti inowedzera uye inobvumirana zvishoma nekuchinja kwekushisa. Ichi chivakwa chinovimbisa kuti nzvimbo yeplate inoramba yakati sandara uye yechokwadi, kunyangwe munzvimbo dzakaoma
Precision Manufacturing
Kuti uwane iwo epamusoro mazinga ekurongeka, granite pamusoro peplateti inopinda yakaoma kugadzira maitiro. Kutanga, iyo granite block yakanyatso kusarudzwa nekuda kwehutano hwayo uye kusagadzikana. Zvadaro, inenge yakashata-yakachekwa kusvika kuhukuru hunodiwa uye chimiro. Tevere kunouya kupeta uye kukwenenzverwa maitiro, uko kumusoro kunonatswa zvishoma nezvishoma uchishandisa abrasive zvinhu. Iyi yekunyatsoita maitiro inogona kuwana yakadzika yakadzika pamusoro roughness uye yakakwirira flatness kushivirira

Accuracy Standards
Kurongeka kwemahwendefa epamusoro pegranite kunowanzo kutsanangurwa nekushivirira kwavo kwegomba. Zvinoenderana neAmerican Society of Mechanical Engineers (ASME) B89.3.7 yakajairwa, mahwendefa epamusoro anoiswa magiredhi zvichienderana nekupfava kwawo. Giredhi repamusoro-soro, AA, rine kushivirira kwakasimba, zvichiita kuti rive rakakodzera macalibration marabhoritari uye yakakwirira-chaiyo metrology. Mahwendefa eGiredhi A anowanzoshandiswa munzvimbo dzekuongorora, nepo mahwendefa eGiredhi B, ane kushivirira zvishoma, anogona kuwanikwa pauriri hwezvitoro.
Semuyenzaniso, 12" x 12" AA-giredhi regiredhi repamusoro ndiro inogona kunge ine flatness tolerance ye ± 0.00005 inches kumativi ayo ose. Iyi nhanho yekurongeka inobvumira kuyerwa kwakanyanya uye macalibrations emamwe maturusi uye zvikamu
Zvinhu Zvinokanganisa Kururama
Nepo mahwendefa epamusoro egranite ari echokwadi, zvinhu zvakati wandei zvinogona kukanganisa kuita kwavo nekufamba kwenguva. Kubata zvisina kunaka, sekudonhedza kana kuisa ndiro kune simba rakawandisa, zvinogona kukonzera machipisi kana kutsemuka kunogona kukanganisa flatness. Pamusoro pezvo, zvinhu zvakatipoteredza zvakaita sekuchinja kwekushisa kwakanyanya kana kuwanda kwehunyoro hunyoro hunogonawo kukanganisa kurongeka kweplate. Kugara uchichenesa uye kugadzirisa, pamwe nekuchengetedza kwakakodzera, zvakakosha kuchengetedza iyo ndiro chaiyo
Mukupedzisa, mahwendefa epamusoro egranite anopa huroyi hunoshamisa, huchiita kuti ive sarudzo yakavimbika yezvishandiso uko iko kurongeka kwakakosha. Kugadzikana kwavo kwechisikigo, kwakasanganiswa nehunyanzvi hwekugadzira nzira, inovabvumira kupa yakagadzikana uye yakaringana referensi nzvimbo yeakasiyana maindasitiri, kubva kune aerospace uye mota kune zvemagetsi uye zvekurapa mudziyo kugadzira.
