I. Te Tukanga Whakaputa o te Granite Straightedge
Te tātari me te tapahi i ngā rauemi mata
Ngā paearu whiriwhiri rauemi: Me whiriwhiri he karāhe kounga teitei, he ≥2.7g/cm³ te matotoru, ā, he < 0.1% te tere mimiti wai (pērā i te "Jinan Green" nō Shandong me te "Black Gold Sand" nō Īnia). Me ōrite ngā matūriki kohuke (ngā matūriki quartz ≤2mm), kāore he kapiti, he pūwero rānei, ā, me tango ngā kōhatu hapa huna mā te kimi hapa hihi-X.
Te tapahi taratara: Whakamahia he kani porowhita taimana hei tapahi i te mea papatahi kia 5-10mm te rahi ake i te rahi o te hua kua oti. Me whakahaere te hapa papatahi o te mata tapahi i roto i te ±0.5mm.
2. Maimoatanga koroheketanga
Te koroheketanga tūturu: Whakatakotoria te tinana matomato ki te rangi tuwhera mō ngā marama e 6 ki te 12. Nā te rerekētanga o te pāmahana i waenganui i te awatea me te pō, me ngā huringa o te haumākū, neke atu i te 90% o te ahotea o roto ka tukuna hei ārai i te whakarerekētanga i te wā o muri mai.
Te whakatōtō horihori (whiringa): Ka whakamahia e ētahi kaihanga he oumu pāmahana pumau (100-150℃) mō ngā hāora 24 hei whakateretere i te tukunga ahotea, he mea e tika ana mō ngā ota ohorere, engari he iti ake te pānga i tērā o te whakatōtō taiao.
3. Te huri taratara me te tukatuka mata tohutoro
Te huri me te hanga taratara: Whakamahia he wira huri taimana 200-400 mata hei huri i te mea papatahi, tangohia ngā rārangi tapahi, whakatikahia te papatahi mai i te ±0.5mm ki te ±0.1mm/m (100μm/m), ka whakatau i te mata tohutoro.
Te maimoatanga mata kāore e mahi ana: Whakakorikoria, pania rānei ngā mata taha me raro (pērā i te rehu peita ārai-waikura) hei ārai i te pakaru o ngā taha me te whānui o te mimiti makuku.
4. Te huri tika (tukanga matua)
Ka tutuki te peke tika mā te huri whakarōpū, e wehea ana kia toru ngā wāhanga:
Huri taratara: Whakamahia ngā mea whakakoi 400-800 mata (te karawiti silicon, te paura taimana rānei) me te papa huri karāhe hei whakatika i te papatahi ki te ±10μm/m, me te taratara o te mata Ra≤0.8μm.
Te huri tika: Mā te huri ki ngā mea whakakoi 1200-2000 me te whakakotahi me te taumata hiko (tika ±1μm/m) mō te aroturukitanga wā-tūturu, kua pai ake te papatahi ki te ±3μm/m, ā, ko te taratara o te mata Ra he ≤0.4μm.
Te huri tino pai (he mea nui ki ngā hua tino tika): Mā te whakamahi i te paura moroiti W10-W5 (rahi matūriki 5-10μm) me te wai whakakanapa matū, mā te mahi takirua o te "huri miihini + waikura matū", ka taea te papatahi whakamutunga ki te ±1μm/m, me te taratara o te mata Ra≤0.2μm.
5. Te kimi me te whakatikatika tika
Ngā taputapu kimi: Ka whakamahia he ine whakawhiti taiaho (tika ±0.1μm) me te taumata hiko (taumira 0.001mm/m) hei kimi i te papatahi me te tika i te whānuitanga katoa, me te tuhi i tētahi mahere tohatoha hapa.
Whakatikatika porowhita-kati: I runga i ngā raraunga kitenga, ka mahia te huri tāpiri ā-rohe ki te wāhi hapa-nui mā te mīhini huri CNC kia whakahaerea rā anō te hapa rahi-katoa i roto i te awhe ūnga.
6. Te tiaki mata me te takai
Maimoatanga tiaki: Rehuhia he paninga silica nano-tauine (5-10μm te matotoru) ki runga i te mata tohutoro, ka pania he paparanga ware pi ārai-waikura ki runga i te mata kore e mahi hei ārai i te mimiti makuku, i te waikura rānei i te wā e whakamahia ana mō te wā roa.
Takai tōtika: Kua tākaihia ki roto i ngā pouaka rakau ātete-ru me ngā mea whakamaroke. I te wā e kawe ana, ka whakahaerehia te rerekētanga pāmahana i roto i te ±5℃ hei karo i te ngoikore o te tōtika i puta mai i te wiri.
II. Te Paerewa Tika me ngā Paerewa Ahumahi Tino Pai
Ko te tika o te taha tika o te karāhe karāhe e ahu mai ana i te hapa papatahi hei tohu matua. E ai ki te paerewa ā-motu (GB/T 4977-2018) me te paerewa o te ao (ISO 2768-2), ko ōna tohu tika me ngā tawhā e rite ana koia ēnei:
Ka taea e ngā taiwhanga tino pai te whakatutuki i te tino tika:
Mā roto i ngā tikanga huri nano-tauine (pērā i te whakakanapa magneorheological me te whakarerekētanga hihi katote), ka taea te pakaru i te papatahi o ētahi hua papai ki te ±0.5μm/m (arā, kāore te hapa mō ia mita e neke ake i te 0.5 micrometer), e tata ana ki te tohutoro papa whatu-tohu. E whakamahia ana ēnei i roto i ngā horopaki tino tika pērā i ngā whare rererangi me ngā whare ine ine.
III. Te Whakataurite i ngā Take e Pā Ana ki te Tika
Whakarāpopototanga: Ko te tino tika o te mata o te karāhe karāhe e whakawhirinaki ana ki te whakahaere katoa o te tukanga o "ngā rauemi mata kounga teitei + te pakeketanga roa rawa + te hurihanga kua whakaritea + te taiao uaua", ko te tukanga hurihanga te kaupapa matua mō te putanga nui o te tika. I te whanaketanga o te hangarau hanga-nano, kei te neke haere tōna tika ki te taumata iti-micron, ā, kua waiho hei taputapu tohu kore e taea te whakakapi i roto i te mara o te hangahanga teitei.
