Mukugadzirwa kwepamusoro-soro uye metrology, granite slab ndiyo nheyo isina kupokana - zero-point referensi yekuyera kuyerwa. Kugona kwayo kubata ndege iri pedyo-yakakwana haisi hunhu hwechisikigo, asi mhedzisiro yemaitiro akanyatsodzorwa ekugadzirisa, anoteverwa nekurangwa, kugadzika kwekugadzirisa. Asi ndeipi rwendo rwechokwadi rwunotorwa negranite kuti uwane kukwana kwakadai, uye ndeapi maprotocol anodiwa kuti aichengetedze? Kune mainjiniya uye maneja emhando, kunzwisisa zvese genesis yeiyi chaiyo uye matanho anodiwa ekuchengetedza kwakakosha kuchengetedza mhando yekugadzira.
Chikamu 1: The Shaping process-Engineering Flatness
Rwendo rwegranite slab, kubva kune yakaomesesa-yakachekwa block kuenda kune referensi-giredhi repamusoro ndiro, rinosanganisira nhevedzano yekukuya, kudzikamisa, uye kupedzisa matanho, imwe neimwe yakagadzirirwa kuderedza zvakanyanya kukanganisa kwedimensional.
Pakutanga, mushure mekucheka, slab inoiswa pasi Rough Shaping uye Kukuya. Iyi nhanho inobvisa huwandu hukuru hwezvinhu kumisikidza iyo inenge yekupedzisira geometry uye yakaomarara flatness. Zvine hutsinye, maitiro aya anoshandawo kusunungura kwakawanda kwekwakasara kushushikana kunovaka mudombo panguva yekuchera nekucheka kwekutanga. Nekubvumidza iyo slab "kugadzika" uye kudzikamisa zvakare mushure mega ega nhanho yekubvisa zvinhu, isu tinodzivirira mune ramangwana dimensional kukukurwa, nekuona kugadzikana kwenguva refu.
Shanduko yechokwadi inoitika panguva Iyo Art yePrecision Lapping. Lapping ndiyo yekupedzisira, yakanyatso hunyanzvi maitiro anokwenenzvera semi-flat nzvimbo kuita ndege yakasimbiswa. Uku hakusi kugaya kwemagetsi; iko kungwarira, kuderera-kumhanya, kwakanyanya-kumanikidza kushanda. Isu tinoshandisa akatsetseka, akasununguka abrasive komisheni - kazhinji madhaimondi slurry - yakaturikwa mumhepo yemvura, inoiswa pakati pepamusoro pegranite uye yakasimba yakakandwa yesimbi yekurombera ndiro. Kufamba kwacho kwakanyatso kudzorwa kuti ive nechokwadi chekubviswa kwezvinhu zvakafanana pamusoro pepamusoro. Iyi avhareji mhedzisiro, inodzokororwa nemaoko uye nemuchina mumatanho ekudzokorora, zvishoma nezvishoma inonatsiridza kupfava kusvika mukati memicrons kana kunyange madiki-microns (kusangana akaomesesa zviyero seASME B89.3.7 kana ISO 8512). Iyo chaiyo inowanikwa pano ishoma nezvemuchina uye zvimwe nezve hunyanzvi hwemushandisi, hwatinoona sechinhu chakakosha, chisingadzoreki.
Chikamu 2: Kuchengeta—Kiyi Yokunyatsorurama
A granite pamusoro peplate chiridzwa chaicho, kwete bhenji rebasa. Kana yangosimbiswa, kugona kwayo kuchengetedza kurongeka kunoenderana zvachose nemushandisi maprotocol uye nharaunda.
Environmental Control ndicho chinhu chimwe chete chikuru chinokanganisa kurongeka kwegranite. Nepo granite iine yakaderera coefficient yekuwedzera kwekupisa (COE), mutsauko wetembiricha pakati pepamusoro nepasi penzvimbo (yakamira tembiricha gradient) inogona kuita kuti slab yese iite dome zvine hungwaru kana kuchinjika. Naizvozvo, ndiro yacho inofanirwa kuchengetedzwa kure nechiedza chezuva chakananga, air conditioning drafts, uye nekupisa kwakawanda. Nzvimbo yakanaka inochengetedza yakagadzikana 68°F ± 1°F (20℃ ± 0.5℃).
Nezve Kushandisa uye Kuchenesa Protocol, kuenderera kushandiswa kwenzvimbo kunokonzeresa kupfeka. Kurwisa izvi, isu tinopa zano nguva nenguva kutenderedza slab pachigadziko chayo uye kugovera kuyerwa kwekuita munzvimbo yese. Kuchenesa nguva nenguva kunosungirwa. Guruva nemarara akatsetseka anoita seabrasives, kukurumidza kupfeka. Chete nyanzvi dzekuchenesa granite, kana yakakwirira-kuchena isopropyl doro, inofanira kushandiswa. Usamboshandisa mishonga yemumba kana yekuchenesa nemvura inogona kusiya zvisaririra zvinonamira kana, kana iri mvura, kutonhora kwekanguva uye kukanganisa pamusoro. Kana ndiro yacho isingaiti, inofanira kuvharwa nekavha yakachena, yakapfava, isingasviki.
Chekupedzisira, nezve Recalibration uye Renewal, kunyangwe nehanya yakakwana, kupfeka hazvidzivisike. Zvichienderana negiredhi rekushandisa (semuenzaniso, Giredhi AA, A, kana B) uye kuremerwa kwebasa, giraniti repamusoro ndiro rinofanira kudzokororwa zviri pamutemo mwedzi mitanhatu kusvika makumi matatu nematanhatu. Nyanzvi yakasimbiswa inoshandisa zviridzwa zvakaita seautocollimators kana laser interferometers kumepu kutsauka kwepasi. Kana ndiro yacho ikawira kunze kwegiredhi rekushivirira, ZHHIMG inopa nyanzvi yekudzokorora masevhisi. Iyi nzira inosanganisira kudzosa iyo chaiyo lap pa-saiti kana kunzvimbo yedu kuti idzorere zvine hungwaru kudzoreredza kwekutanga kwakasimbiswa flatness, kunyatsogadzirisa hupenyu hwechishandiso.
Nekunzwisisa magadzirirwo epamusoro-soro uye kuzvipira kuhurongwa hwekugadzirisa, vashandisi vanogona kuona kuti mahwendefa avo epamusoro pegranite anoramba ari hwaro hwakavimbika kune zvese zvavanoda zvemhando yepamusoro, gumi mushure memakore gumi.
