Mapureti epamusoro egranite akanyatsogadzirwa anoonekwa zvakanyanya sehwaro hwekuyera kwakarurama uye masisitimu ekubatanidza. Kubva kumarabhoritari emetrology kusvika kuunganidzwa kwemidziyo ye semiconductor uye nzvimbo dzakarurama dzeCNC, mapuratifomu egranite anovimbwa nekuda kwekugadzikana kwawo, kuramba kupera, uye maitiro ekupisa. Asi mubvunzo unowanzo bvunzwa nemainjiniya nevatariri vemhando yepamusoro uri nyore kunyengera: kururama kwepuratifomu yegranite inochengetedza nguva yakareba sei, uye kugadzikana kwenguva refu kwekururama kunofanira kuva chinhu chakakosha pakusarudza imwe here?
Kusiyana nezvishandiso zvinodyiwa kana zvikamu zvemagetsi, achikuva chegranite chakanyatsojekaHaina "zuva rekupera" rakatarwa. Nguva yayo yekushanda zvakanaka inoenderana nekusanganiswa kwemhando yezvinhu, maitiro ekugadzira, mamiriro ekushandiswa, uye kudzora nharaunda kwenguva refu. Mukushandiswa kwakanaka, granite surface plate yemhando yepamusoro inogona kuchengetedza kutsetseka kwayo kwakatarwa kwemakumi emakore. Zvisinei, munzvimbo dzisina kudzorwa zvakanaka, kudzikira kwekururama kunogona kuitika nekukurumidza, dzimwe nguva mukati memakore mashoma.
Chigadzirwa chacho pachacho chinoita basa guru mukugadzikana kwenguva refu. Granite nhema ine density yakakura ine chimiro chakaenzana, inopa simba guru pakudzikama kwemukati uye kukanganisika kwemukati nekufamba kwenguva. Granite ine density inosvika 3100 kg/m³ inoratidza hunhu hwakanaka hwekunyorovesa uye maitiro ekudzikama zvishoma, izvo zvakakosha kuti irambe yakati sandara pasi pemitoro inoenderera mberi. Matombo ane density yakaderera kana zvinhu zvakasarudzwa zvisina kunaka, kusanganisira marble zvikashandiswa zvisirizvo segranite, zvinogona kutanga kusangana nezvinodiwa zve flatness asi zvinowanzo famba nekukurumidza sezvo internal stress dzinobuda panguva yekushandiswa.
Hunhu hwekugadzira hwakakoshawo. Mapuratifomu egranite akagadzirwa zvakanaka anogadziriswa, anorerutswa nekushushikana, uye anochembera kwenguva refu asati agerwa kwekupedzisira anoratidza kugadzikana kuri nani kwenguva refu. Matekiniki epamusoro ekugeda uye kurovera maoko kunoitwa nematekiniki ane ruzivo kunoita kuti kutsetseka kwepamusoro kusvike pamazinga e micrometer kana nanometer. Chinonyanya kukosha ndechekuti, maitiro aya anoita kuti chimiro chepamusoro chirambe chakasimba mushure mekuiswa, pane kuchinja zvishoma nezvishoma sezvo kushushikana kwasara kuchipera. Mapuratifomu akagadzirwa asina kuchembera kwakakwana kana kuti kutenderera kwekugadzira nekukurumidza anowanzo ratidza kurasikirwa kwekururama kunoyerwa nekufamba kwenguva, kunyangwe kana mishumo yekutanga yekuongorora ichiratidzika kunge inoshamisa.
Mamiriro ekunze ane simba rinoramba riripo uye rinowedzera pakurarama kwekururama kunoshanda kwemunhundiro yepamusoro yegranite. Kuchinja-chinja kwetembiricha, rutsigiro rusina kuenzana, kusvibiswa kwekudengenyeka, uye kuchinja kwehunyoro zvese zvinopa njodzi dzekuchinja kwenguva refu. Granite ine coefficient yakaderera yekuwedzera kwekupisa, asi haina kudzivirirwa kumazinga ekupisa. Chikuva chinoonekwa pakuchinja-chinja kwekupisa kwezuva nezuva kana masosi ekupisa ari munzvimbo imwe chete chinogona kusangana nekukombama kudiki kunokanganisa kuvimbika kwekuyera. Ndokusaka kugadzikana kwenguva refu kwekururama kusingaparadzaniswi nekuiswa kwakakodzera, nzvimbo dzekutsigira dzakagadzikana, uye nzvimbo yekuyera yakadzorwa.
Maitiro ekushandisa anoonawo kuti kururama kunoramba kuri kwenguva yakareba sei mukati mezvakatarwa. Puratifomu yekunyatsojeka yegranite inoshandiswa senzvimbo yekutarisa mabasa ekuyera chiedza ichakwegura zvakasiyana neinotsigirwa nezvikamu zvinorema zvemuchina kana mitoro inodzokororwa inochinja-chinja. Mitoro yakaomeswa, kusimudza zvisina kunaka, kana kutamiswa nguva nenguva kunogona kuunza kushushikana kudiki muchimiro. Nekufamba kwenguva, kushushikana uku kunogona kuchinja chimiro chepamusoro, kunyangwe mugranite yemhando yepamusoro. Kunzwisisa kuti puratifomu ichashandiswa sei mumamiriro ezvinhu chaiwo kwakakosha pakuongorora mashandiro enguva refu ekunyatsojeka.
Maitiro ekugadzirisa nekugadzirisa anoratidza zvakajeka kuti puratifomu inoshanda kwenguva yakareba sei. Pane kufunga kuti iine nguva yakatarwa yebasa, vashandisi vane hunyanzvi vanovimba nekuongorora nguva nenguva kuti vaone kuti kutsetseka uye geometry zvinoramba zviri mukati mekutsungirira. Munzvimbo dzakagadzikana, nguva dzekugadzirisazve kwegore rimwe kusvika maviri dzakajairika, uye mapuratifomu mazhinji anoratidza kutsauka kudiki kunyangwe mushure menguva yakareba yebasa. Munzvimbo dzakaoma dzemaindasitiri, kuongororwa kakawanda kunogona kudiwa, kwete nekuti granite inoora nekukurumidza, asi nekuti pesvedzero yezvakatipoteredza inoungana nekukurumidza.
Pakusarudza plate yegranite ine kunyatsogadzirwa, kugadzikana kwenguva refu kwekururama hakufanirwe kutorwa sepfungwa yekuzotevera. Hunhu hwekutanga hwekutsetseka chete hahuratidzi mashandiro epuratifomu iyi makore mashanu kana gumi gare gare. Mainjiniya anofanirwa kufunga nezvehunhu hwegranite, kukwegura kwayo, nzira dzekugadzira, uye kuenderana kwayo nenzvimbo yaunoda. Puratifomu yegranite yakasarudzwa zvakanaka inova chinhu chenguva refu pane kugara ichitarisirwa.
Mumaindasitiri emazuva ano ane kunyatsorurama, kururama hakungoyerwi panguva yekuendeswa chete. Kunoyerwa nekufamba kwenguva, pasi pemutoro, uye mumamiriro ezvinhu anochinja. Puratifomu yekunyatsorurama yegranite inochengetedza geometry yayo gore negore inotsigira mhedzisiro yekuyera yakafanana, kubatanidza michina kwakavimbika, uye kuderedzwa kwemitengo yekudzokorodza. Izvi zvakakosha zvakanyanya mumashandisirwo akadai sekugadzira semiconductor, kuongorora kwemaziso, michina yekuyera yakabatana, uye masisitimu emhando yepamusoro eCNC, uko kunyangwe kutsauka kudiki kunogona kupararira kuita zvikanganiso zvakakura.
Pakupedzisira, kukosha kwechokwadi kweplate ye granite pamusoro pechinhu chakanyatsogadzirwa kuri mukukwanisa kwayo kuramba yakasimba kwenguva refu mushure mekuiswa. Nekuisa kukosha kwekugadzikana kwenguva refu panguva yekusarudza, vashandisi vanogona kuve nechokwadi chekuti hwaro hwavo hwekuyera hunoramba hwakavimbika mukati mehupenyu hwese hwemidziyo yavo. Mukugadzira michina nekunyatsogadzirwa, kugara kwenguva refu hakusi chinhu cheumbozha; ndiyo chiyero chemhando yepamusoro.
