Munyika yekugadzira zvinhu zvemazuva ano, granite surface plate ndiyo gamba risingazivikanwe relaboratory yekudzora mhando. Inopa nzvimbo yakakwana yekutarisisa inodiwa padanho rega rega rekuongorora, kubva pabasa riri nyore rekugadzira kusvika pakuenzanisa kwakaoma. Zvisinei, kunyange granite nhema yepamusoro haisi chishandiso chekuti "ita kuti iite zvakanaka uye ukanganwe". Nekuti kururama kwemutsara wako wese wekugadzira kunoenderana nekusatsetseka kwedombo iri, kuchengetedza uye kugadzirisa mapuratifomu ako egranite surface chinhu chakakosha pakushanda. Pasina nzira yakasimba yekugadzirisa, kunyangwe plate yeGrade 00 laboratory inogona kukurumidza kuora kuita sosi yekukanganisa kuyera, zvichikonzera kurambwa kunodhura uye kukanganisa kuvimbika kwechigadzirwa.
Kunzwisisa Kutenderera Kwehupenyu Hwakarurama
Purati yegranite inosarudzwa nekuda kwekugadzikana kwayo kwechisikigo, kudzikamisa kutenderera, uye kuramba kupisa. Painotanga kusvika kubva kumugadziri, inoperekedzwa nechitupa chekuongorora chinoratidza kuti yakati sandara. Zvisinei, kubva panguva yainoiswa, inotanga kusangana nemamiriro ayo. Kukakavadzana kubva pazvishandiso zvebasa, kuunganidzwa kweguruva risingaonekwe, uye kuchinja kudiki kwenheyo yechivako zvese zvinoita basa mukushanduka kwepurati.
Kugadzirisa hakusi kungochengetedza ndiro yakachena chete; asi kuchengetedza hunhu hwenzvimbo yacho inowanzo tetepa kusvika pamadhora $0.001$ mm. Patinotaura nezve "kuchengetedza" ndiro yepamusoro, tiri kutaura nezvekudzivirira kusakara. Patinotaura nezve "calibration," tiri kutaura nezvekuyera nekugadzirisa kusakara ikoko. Pamwe chete, maitiro aya anovimbisa kuti gwara rako rekutarisa rinoramba riripo munzvimbo yekugadzira inogara ichichinja.
Kuranga Kwezuva Nezuva Kwehutsanana Hwepamusoro
Muvengi mukuru weplate yegranite pamusoro pevhu i "ivhu remuchitoro." Munzvimbo yekugadzira, mhepo inozadzwa nezvidimbu zvidiki-diki—guruva resimbi, mhute inotonhodza, uye silica. Kana workpiece inorema yakaiswa paplate yevhu isina kucheneswa, zvikamu izvi zvinoshanda sesandpaper yeindasitiri. Sezvo chikamu ichi chichifamba pamusoro, chinoita "nzvimbo dzakaderera" kana "mipata" mugranite. Nekufamba kwenguva, nzvimbo idzi dzakaderera dzinova dzakakosha zvakakwana kuti dzibvise kuverenga kwegeji yekukwirira kana kudzivirira chikamu kuti chisagare pamwero.
Kuchenesa zuva nezuva ndiyo nzira yekutanga yekudzivirira. Chikanganiso chinowanzoitika kushandisa michina yekuchenesa magirazi epamba kana michina yekubvisa mafuta mumaindasitiri pagranite. Mazhinji acho ane makemikari anogona kusiya firimu diki kana, zvakatoipa, kupinda mumaburi edombo oita kuti rikwezve guruva rakawanda. Michina yekuchenesa mapurasitiki egranite yakagadzirwa kuti ibvise tsvina nemafuta uku ichipwa zvachose, isingasiyi zvasara. Maitiro ekuchenesa anofanira kugara achishandisa jira risina jira uye anofanira kuitwa nguva dzese usati watanga basa uye mushure mebasa rega rega.
Uyezve, "nzira" yekushandisa ndiro inokosha. Vashandi vanofanira kudzidziswa kuti vasambo "donhedza" chinhu chebasa pagranite. Kunyangwe granite yakaoma zvikuru, kurovera kwakasimba kubva muchikamu chesimbi chinorema kunogona kukonzera "kutsemuka kwenyeredzi" kana "maburrs." Kunyange zvazvo granite isingade "howa" kana yarohwa, chimedu chiri pamusoro chinogona kugadzira nzvimbo yakakwirira inofanira kudonhedzwa nedombo rekushongedza resilicon carbide.
Sainzi yeKuenzanisa: Kupfuura Zvinoonekwa
Kuenzanisa inzira yekuona kuti plate yacho yakatsetseka ichiri kusvika padanho rayo rakatarwa (senge Giredhi 0, 1, kana 2). Mabhizinesi mazhinji anoita chikanganiso chekufungidzira kuti plate yacho yakatsetseka nekuti inotaridzika zvakanaka. Muchokwadi, kupera kweplate pamusoro peplate hakuonekwe nemaziso ese. Kazhinji kunoitika pakati peplate, uko basa rekuongorora rinoitwa, zvichigadzira "ndiro".
Kuongororwa kwehunyanzvi kunosanganisira zviyero zviviri zvakasiyana: kutsandama kwese uye kudzokorora kuverenga kwakarurama. Kutsandama kwese kunowanzo kuyerwa uchishandisa electronic level kana laser interferometer. Nyanzvi inofambisa sensor pamusoro peplate nenzira ye "Mood's Bridge" kana "Union Jack", ichiratidza topography yenzvimbo yese. Ruzivo urwu runobva rwagadziriswa kuitira kuti pasave nenzvimbo iri muplate inopfuura kutsauka kunobvumirwa kubva paavhareji.
Kuverenga kwakarurama, kunowanzoitwa ne "Dzokorora-O-Meter," kunoongorora kusakara kwenzvimbo. Inotevedzera geji yekukwirira iri kutamiswa pamusoro penzvimbo diki kuti ive nechokwadi chekuti chiyero chacho chinoramba chakafanana. Purati inogona kupasa bvunzo yekusatsetseka asi ikakundikana bvunzo yekudzokorora kuverenga kana paine nzvimbo diki, yakadzika yekusakara munzvimbo inoshandiswa zvakanyanya. Kune vagadziri vanoita basa rekutumira kunze kwenyika, kuva nemushumo wekuongorora wakabvumidzwa weISO/IEC 17025 kazhinji chinodiwa pachibvumirano, sezvo ichipa humbowo hwechokwadi hunodiwa nevatengi vepasi rose.
Kutenderera uye Kutarisira Mutoro
Kuti vawedzere nguva pakati pezvikamu zvinodhura zvekudzokorora, nzvimbo dzakangwara dzinodzidzira kutonga mutoro. Kana plate yepamusoro yakakura, basa rekuongorora rinofanira kutenderedzwa muzvikamu zvakasiyana zveplate. Kana geji yekukwirira yakagara iri mukona yekumberi-kurudyi, kona iyoyo ichasakara nepo imwe plate yasara ichiramba yakachena. Nekusiyanisa nzvimbo yebasa, kusakara kunogoverwa zvakaenzana, zvichichengetedza kusatana kwenguva yakareba.
Pamusoro pezvo, sisitimu yekutsigira yeplate—kazhinji kacho stand ine mapoinzi matatu kana mashanu—inofanira kuongororwa nguva nenguva. Granite inorema, uye nekufamba kwenguva, stand inogona kugara pasi rekongiri risina kuenzana zvakakwana. Kunyange zvazvo stand isina kuenzana zvishoma isinga "konzere" granite (nekuda kwekuoma kwayo kwakanyanya), zvinogona kuita kuti zviome kushandisa ma level emagetsi anonzwa panguva yekuongorora workpieces. Kuva nechokwadi chekuti plate yakaenzana zvichienderana ne support points dzekutanga dzemugadziri kwakakosha kuti pave nemhedzisiro yakafanana.
Nguva Yokudzokorora: Nguva Yokusadzoka
Pakupedzisira, ndiro yega yega yepamusoro ichasakara kupfuura zvainokwanisa. Padanho rino, kuyera hakuchakwani; ndiro yacho inofanira "kudzokororwazve." Iyi inzira yemaoko ine hunyanzvi apo nyanzvi inoshandisa dhaimani kana silicon carbide slurry uye "rongero" diki kuti ikweshe pamusoro payo kuti pave patete.
Kuisa jira patsva inyanzvi pamwe chete nesainzi. Nyanzvi inofanira kubvisa zvinhu zviri panzvimbo dzakakwirira ichiramba ichiongorora kufambira mberi kwayo nemagetsi. Kune jira rakaregeredzwa zvakanyanya, maitiro ekuisa jira patsva anogona kutora maawa akati wandei kana mazuva. Zvisinei, kana yaitwa nemazvo, inodzorera jira patsva kuti rive "rayo" pakutanga, zvichiita kuti rive idzva.
Kudzora Zvakatipoteredza uye Kugadzikana Kwekupisa
Pakupedzisira, nharaunda yakakomberedza ndiro inofanira kutarisirwa. Granite ine kupisa kwakanyanya, zvinoreva kuti zvinotora nguva yakareba kuti tembiricha ichinje. Zvisinei, kana ndiro yepamusoro ikaiswa zvakananga pasi pemhepo inobuda neHVAC kana munzira yezuva rakananga kubva pahwindo, rimwe divi rendiro rinogona kudziya kupfuura rimwe. Izvi zvinogadzira "kupisa kwakanyanya" kunogona kukonzera kuti ndiro ikotame zvishoma.
Kunyange hazvo hunhu hwe "Zero-Expansion" hwegranite nhema (senge ZHHIMG granite) huchideredza izvi, hahubvisi zvachose padanho re sub-micron. Zvakanaka kuti maplate anofanirwa kuchengetwa munzvimbo inodzorwa tembiricha ye20℃ (68℉) ine hunyoro huri pakati pe40% ne50%. Kana plate ikabviswa padock inotonhora kuenda ku lab inodziya, inofanira kubvumirwa "kunyikwa" kwemaawa angangoita 24 kusvika ku48 isati yaedzwa kuyedza kuyera kana kuyera kwakanyatsojeka.
Mhedziso: Nheyo Yakakodzera Kudzivirirwa
Kuchengetedza nekugadzirisa ndiro yegranite inyaya yechokwadi. Munguva ino apo kushivirirana kwekugadzira kwakaoma kupfuura kare, haugone kuva ne "hwaro hwekusava nechokwadi." Nekutevera nzira yakasimba yekuchenesa zuva nezuva, kubata zvidimbu zvebasa nokungwarira, uye kugadzirisa nguva dzose, unoshandura ndiro yako yekumusoro kubva padombo kuita chishandiso chinoshanda zvakanaka.
Kune vanotumira kunze kwenyika nevanotenga michina yemuno, meseji yacho yakafanana: mhando yechinhu chaunoburitsa hachimbofi chakapfuura pamusoro pacho. Bata granite yako neruremekedzo rwayo, uye ichapa hwaro hwechokwadi hunodiwa nebhizinesi rako kuti ribudirire mumusika wepasi rose une makwikwi.
