Granite pamusoro mahwendefa maturusi anokosha mukuyera uye kugadzira, asi haasi ese mahwendefa anogadzirwa akaenzana. Giredhi A uye Giredhi B mahwendefa epamusoro pegranite anosiyana zvakanyanya maererano nekurongeka, kupera kwepamusoro, mamiriro ekushandisa, uye mutengo. Kunzwisisa misiyano iyi kunobatsira maindasitiri kusarudza iyo yakanyatsokodzera sarudzo yezvavanoda chaizvo.
Kushivirira kweFlatness: Iyo Core yePrecision
Flatness tolerance ndiyo inonyanya kusiyanisa pakati pemagiredhi maviri. Zvinoenderana neAmerican Society of Mechanical Engineers (ASME) B89.3.7 chiyero, mahwendefa eGiredhi A anopa kunyatsojeka. Semuyenzaniso, pandiro yegumi nembiri” x 12”, Giredhi A rinowanzova nekushivirira kwe ± 0.00008 inches, kuve nechokwadi chekuti nzvimbo inenge yakakwana yakati sandara. Mukupesana, Giredhi B mahwendefa ane looser tolerances, akatenderedza ± 0.00012 inches yehukuru hwakafanana. Musiyano uyu unoita kuti Giredhi A rive rakanaka kune zvikumbiro zvinoda kurongeka zvakanyanya, sekuenzanisa zviridzwa zvekuyeresa zvakakwirira, ukuwo Giredhi B rinokwana mabasa ekuongorora zvakazara mumashopu.
Kushata Kwepamusoro: Kukanganisa Pakuyera
Surface roughness zvakare inosiyana pakati pemagiredhi. Mahwendefa eGiredhi A anoenda zvakanyanya kupeta uye kukwenenzverwa maitiro, zvichikonzera nzvimbo yakatsetseka ine roughness avhareji (Ra) kazhinji iri pasi pe0.0005 inches. Iyi yekupedzisira - yakatsetseka kupera inoderedza kukweshera uye inodzivirira kukwenya pazvinhu zvakatetepa panguva yekuyera. Mahwendefa eGiredhi B, ane kukosha kweRa kutenderedza 0.001 inches, akakora. Kunyangwe vachigona kuita mabasa ekuyeresa, anogona kunge asina kukodzera kubata nhengo dzinonzwa.
Mamiriro ekushandisa: Kufananidza kune Zvinodiwa
Sarudzo pakati peGiredhi A neGiredhi B inoenderana zvakanyanya nekushandisa. Mukugadzira aerospace uye semiconductor, uko micrometer - nhanho chaiyo yakakosha, mahwendefa eGiredhi A anosarudzwa. Semuenzaniso, pakuyera kudzika kweturbine blade kana kurongeka kwemamicrochips, kunyangwe kutsauka kudiki kunogona kukanganisa kuita kwechigadzirwa. Giredhi B mahwendefa, zvisinei, anowanzoshandiswa mukugadzira mota, general machining, uye masangano edzidzo. Iwo akakwana kuti atarise hukuru hweinjini mabhuroko kana kudzidzisa ekutanga kuyerwa misimboti pasina kudiwa kweiyo yekupedzisira - yakanyanya kurongeka.
Kugadzira Maitiro uye Mutengo: Kutengeserana - offs Kufunga
Mapureti eGiredhi A anoda hunyanzvi hwekugadzira maitiro. Mhizha dzinopedza nguva yakawanda pakusarudza zvinhu, kucheka chaiko, uye kuwanda-kupurudzira nhanho kuti uwane iyo inodiwa flatness uye kupera kwepamusoro. Iyi nhanho yepamusoro yehunyanzvi, pamwe nekudiwa kwehutongi hwemhando yepamusoro, inokwidza mitengo yekugadzira. Nekuda kweizvozvo, mahwendefa eGrade A anowanzo kudhura ne30 - 50% pane mamwe eGrade B. Kune bhajeti - maindasitiri anoziva kana maapplication ane zvishoma zvinoda kunyatsoita zvinodiwa, mahwendefa eGrade B anopa mutengo - unoshanda imwe nzira.
Muchidimbu, Giredhi A uye Giredhi B mahwendefa epamusoro pegranite anoenderana nematanho akasiyana ehutsanana uye zvinodiwa zvekushandisa. Nepo Giredhi A richikwirisa munzvimbo dzepamusoro-soro, huchokwadi - nharaunda dzinofambiswa, Giredhi B rinopa kuita kwakavimbika nemutengo wakaderera wekushandiswa kwese - chinangwa. Nekunyatsoongorora misiyano iyi, vagadziri nevashandisi vanogona kuita sarudzo dzine ruzivo dzinogonesa zvese nemazvo uye mutengo - kushanda.
