Haere ki roto i tētahi toa mīhini tino tika, taiwhanga whakatikatika, whare huihuinga rererangi rānei puta noa i Ūropi, i Amerika Te Raki rānei, ā, tera pea ka kitea e koe tētahi mea e mōhiotia ana: he papa kōhatu pango, kanapa e mahi ana hei turanga puku mō ngā inenga nui. Koinei te Pereti Mata Kōhatu—he pou tokomanawa o te ine ine mō te neke atu i te haurua rautau. Engari anei tētahi pātai e pātaihia ana e te hunga ruarua: kei te tika te mahi a taua pereti, kei te ngoikore rānei nā te āhua o te tāutanga, te tautoko, me te tiaki?
Ko te pono, hePereti Mata Graniteehara i te mea he kōhatu papatahi noa iho. He taonga kua whakatikatikaina—he whakaaturanga ā-tinana o te pono āhuahanga. Heoi, he maha rawa ngā kaiwhakamahi e whakaaro ana he rite ki te tāonga whare: he mea whakapiri ki tētahi anga ngoikore, he mea whakanoho tata ki tētahi pūtake wera, he mea waiho rānei kia kore e whakatikatikaina mō ngā tau i raro i te whakaaro "kāore te karāti e rerekē." Ahakoa he pono he tino pumau te karāti ki ngā konganuku, kāore e ātete ki ngā hapa. Ā, ina honoa ki ngā taputapu tairongo pērā i ngā ine teitei, ngā tohu mata, ngā whakataurite whatu rānei, ahakoa he 10-micron te rerekētanga ka taea te heke ki ngā whakatau hē utu nui.
Koinei te wāhi e tino kitea ai te rerekētanga i waenga i te pereti tahanga me te pūnaha katoa. Ehara i te mea he mea ngāwari noa iho te whakamahi i te Pereti Mata Granite me te tūnga – engari he mea tika mō te pono o te ine. Ehara te tūnga i te taputapu tāpiri; he wāhanga hangarau e whakarite ana kia noho papatahi, kia pumau, kia wātea hoki te pereti i raro i ngā āhuatanga o te ao tūturu. Ki te kore, ka taea e te granite kounga teitei te piko, te wiri, te neke rānei – ka whakararu i ngā inenga katoa e mahia ana ki runga.
Me tīmata tātou ki te rauemi tonu. Ko te karāhe pango taumata-ira—e ahu mai ana i ngā rua keri pai, ā, e whakaitihia ana te ahotea i Īnia, Haina, Scandinavia rānei—e whiriwhiria ana mō tōna hanganga isotropic, te iti o te horapa wera (tata ki te 6–8 µm/m·°C), me ōna āhuatanga whakamākū tūturu. Kāore i rite ki te rino maka, e waikura ana, e pupuri ana i ngā ahotea miihini, ā, e whānui haere ana me te pāmahana, ka noho tonu te karāhe i te āhua ōrite puta noa i ngā taiao awheawhe noa. Koia te take e kī ana ngā paerewa o te ao pērā i te ASME B89.3.7 (US) me te ISO 8512-2 (ao whānui) ko te karāhe anake te rauemi e whakaaetia ana mō ngā pereti mata tika e whakamahia ana i roto i te whakatikatika me te tirotiro.
Engari kāore e ranea te rauemi anake. Whakaarohia tēnei: ko te taumaha o tētahi Pereti Mata Granite paerewa 1000 x 2000 mm e tata ana ki te 600–700 kg. Mēnā ka whakatakotoria ki runga i tētahi papa koretake, ki tētahi anga kore-mārō rānei, ka taea e te kaha ā-papa anake te whakaputa i ngā piko iti—ina koa i waenganui. Tērā pea kāore e kitea ēnei piko e te kanohi engari ka taea te ine mā te ine i te interferometry, ā, ka takahi tika i ngā ātete papatahi. Hei tauira, me pupuri e tētahi pereti Tau 0 o taua rahi te papatahi i roto i te ±13 microns puta noa i tōna mata katoa e ai ki te ISO 8512-2. Tērā pea ka nui ake i tērā te taumaha o tētahi pereti kāore i te tino tautokona—ahakoa kua tino pai te takai o te granite.
Koinei te mana—me te hiahia—o tētahi whare i hangaia mō tētahi kaupapaPereti Mata Graniteme te tūnga. He nui atu ngā mahi a te tūnga kounga teitei i te whakaara ake i te pereti ki te teitei ergonomic (te tikanga 850–900 mm). Ka whakaratohia he tautoko e toru-ira, e maha-ira rānei kua tatauhia kia rite ki ngā pūnga tūturu o te pereti hei ārai i te piko. Kei roto ko te tautoko whakawhiti pakari hei ātete i te hurihanga. He maha ngā waewae whakaiti wiri, ngā papa wehe rānei hei tiaki i ngā raruraru e pā ana ki te papa mai i ngā mīhini tata. Ko ētahi he pito whenua hei whakakore i te hiko - he mea nui i roto i ngā mahi hiko, i ngā mahi rūma ma rānei.
I ZHHIMG, kua mahi tahi mātou me ngā kiritaki i whakaaro he "pai rawa" tā rātou pereti karāhe nā te mea he maeneene te āhua, ā, kāore i pakaru. I kitea e tētahi kaiwhakarato motuka i Midwest ngā pānui whakahāngaitanga koretake o ngā pouaka tuku. I muri i te tirotirohanga, ehara i te CMM, i te kaiwhakahaere rānei te take—he anga maitai hanga-kāinga i piko i raro i te kawenga. Nā te huri ki tētahi Pereti Mata Karāhe whaimana me te tū, i hangaia kia rite ki ngā aratohu ASME, i whakakorea te rerekētanga i te pō kotahi. I heke iho tā rātou tere para mā te 30%, ā, i ngaro atu ngā amuamu a ngā kiritaki.
Ko tētahi atu hapa noa ko te whakatikatika. Me whakatikatika anō i ia wā te Pereti Mata Granite—ahakoa he mea motuhake, he mea whakairi rānei—kia mau tonu ai te pono. E taunaki ana ngā paerewa kia whakatikatika anō i ia tau mō ngā pereti e whakamahia ana, ahakoa ka taea e ngā taiwhanga tino tika te mahi i ia ono marama. Ehara te whakatikatika pono i te mea he mea noa; ko te mahere i ngā rau o ngā pūwāhi puta noa i te mata mā te whakamahi i ngā taumata hiko, ngā autocollimator, ngā interferometer laser rānei, kātahi ka whakaputa i tētahi mahere āhua e whakaatu ana i te pekapeka mai i te tihi ki te awaawa. He mea nui ēnei raraunga mō te hanganga ture ISO/IEC 17025 me te rite ki te arotake.
He mea nui anō hoki te tiaki. Ahakoa kāore e hiahiatia he paninga hinu, he paninga motuhake rānei mō te karāhe, me horoi tonu ki te waipiro isopropyl hei tango i ngā toenga wai whakamatao, ngā maramara whakarewa, te puehu rānei ka uru ki roto i ngā pūwero moroiti. Kaua rawa e whakatakoto tika i ngā taputapu taumaha ki runga i te mata me te kore he papa tiaki, ā, kaua e tōia ngā poraka ine - me hiki ake, me whakanoho tonu. Puritia te pereti kia hipokina ina kore e whakamahia hei ārai i ngā poke o te hau.
I te wā e whiriwhiri ana i tētahi Pereti Mata Granite, kaua e titiro ki te āhua ataahua anake. Manatokohia:
- Te taumata papatahi (Tohu 00 mō ngā taiwhanga whakatikatika, Tohu 0 mō te tirotiro, Tohu 1 mō te whakamahinga whānui)
- Tiwhikete ki te ASME B89.3.7, ISO 8512-2 rānei
- He mahere papatahi taipitopito—ehara i te mea he tauākī pāhi/kore noa iho
- Te pūtake me te kounga o te karāneti (he kakano pai, kāore he pakaru, he uaua quartz rānei)
Kaua rawa e whakaititia te tūnga. Pātai atu ki tō kaiwhakarato mēnā kua hangaia mā te whakamahi i te tātaritanga hanganga, mēnā kei roto ngā waewae whakataurite, ā, mēnā kua whakamatautauria te huihuinga katoa i raro i te kawenga. I ZHHIMG, ko ia Pereti Mata Granite me te tūnga e tukuna ana e mātou he raupapa, he manatoko takitahi, ā, he tiwhikete NIST-traceable hoki. Kāore mātou e hoko pereti—ka tukuna e mātou ngā pūnaha ine.
Nā te mea, i te mutunga, ehara te tika i te mea ko te whai i ngā taputapu tino utu nui. Engari ko te whai i tētahi turanga ka taea e koe te whakawhirinaki. Ahakoa kei te tirotiro koe i tētahi mata tāpine, kei te whakarite i tētahi matua pokepoke, kei te whakatikatika rānei i tētahi rōpū ine teitei, ka tīmata ō raraunga ki te mata i raro iho. Mena kāore taua mata i te tino papatahi, i te pumau, i te whai rānei, he whakapae ngā mea katoa i hangaia ki runga.
Nō reira, pātai atu ki a koe anō: ina tangohia e koe tō inenga tino nui i tēnei rā, kei te māia koe ki tō tohutoro—kei te tumanako tonu rānei koe kei te tika? I ZHHIMG, e whakapono ana mātou ehara te tumanako i te rautaki ine. Ka āwhina mātou i a koe ki te whakakapi i te koretake ki te mahi kua manatokohia—nā te mea ka tīmata te tino tika mai i te whenua ki runga.
