I roto i te ao tino aunoa o te hangarau tino tika, i te wā e whakahaerehia ana e ngā pūnaha aroturuki laser matatini me ngā rauropi matatau te whakahaere nekehanga, tera pea te ahua rerekē ko te tika o te āhuahanga tino pai kei te whakawhirinaki tonu ki ngā taputapu mai i ngā rā tōmua o te ine ine. Heoi, i te mea e neke hohonu ana te umanga ki ngā rohe iti-micron me te nanometer, ko te tūranga taketake o ngā taputapu karāhe tino tika—ina koa ko te rūri tika karāhe me te tika o te Grade 00, te tapawhā karāhe, me tekarāhe tapawhā toru—ehara i te mea ka tautokona noa, engari ka whakanuia. Ko ēnei taputapu pūmau, kore mahi, ngā tohutoro pumau e whakamana ana i te mahi a ngā pūnaha hihiri tino matatau.
Ko te hiranga o ēnei taputapu tohutoro karāhe i ahu mai i tētahi mātāpono ā-tinana taketake: te pumau o te wera me te miihini. Me whakarite e tētahi mīhini i hangaia mō te tino tika kia pono, kia tika, kia poutū hoki ōna papa ine me te haere raina. Ina hiahiatia e te hanga hou te pumau o ngā āhuatanga kāore e pāngia e ngā huringa pāmahana, e ngā wiri o waho rānei, ka rahua ngā rauemi pēnei i te maitai, te rino maka rānei—me tōna tauwehenga whānui wera (CTE) teitei me te iti o te kaha whakamātao—i te whakamātautau.
Ko te karāneti ia, he taiao tino pai mō te pumau. Nā te iti o te CTE, he iti noa te nekehanga o ngā āhuatanga e puta mai i ngā huringa pāmahana, ā, he rauemi tino pai mō te tautuhi i tētahi papa tohutoro e mau tonu ana te matapae. Hei tāpiri, ko tōna kaha whakamātao teitei ka mimiti tere i ngā wiri, ka ārai i te haruru me te oro e horapa ana e ngā taputapu whakarewa, he mea nui tēnei i roto i ngā taiwhanga ine me ngā taiao huihuinga e wero tonu ana te haruru o te taiao.
Te Pūtake o te Whakarārangi: Te Rūri Tika o te Granite me te Tika o te Tau 00
Ko te ine i te tika te tūāpapa o te ine inenga. Ko ia aratohu rārangi, te whāngai hau, me te tuaka CMM e whakawhirinaki ana ki tētahi ara nekehanga tika ka taea te manatoko. Mō ngā tono tino uaua, ko te rūri tika karāhe me te tika o te Karaehe 00 te mana tino tika.
Ko te tohu o te Grade 00 (te rite rānei ki te Master Grade) e tohu ana i te taumata teitei rawa o te tika ka taea te whakatutuki i waho atu i ngā taiwhanga paerewa ā-motu. Ko tēnei taumata o te tika e hiahia ana kia inehia te rerekētanga tika i te taha mahi katoa o te rūri i roto i ngā haurua o te micron. Hei whakatutuki i tēnei taumata o te pono o te āhuahanga, ehara i te mea ko te rauemi tino pai anake engari me te tukanga hanga e tino whakahaeretia ana.
Me piri te tukanga hanga ki ngā whakaritenga o te ao, pērā i ngā paerewa DIN, JIS, ASME, GB rānei. Mā ēnei paerewa o te ao e tohutohu ngā tikanga whakamātautau, ngā āhuatanga taiao, me ngā manawanui e whakaaetia ana. Mō ngā kaihanga e mahi ana ki ngā kiritaki o te ao—mai i ngā kamupene haurua-ā-ringa Hapanihi ki ngā kaihanga taputapu mīhini Tiamana—ko te kaha ki te whakamana i tētahi rūri tika karāhe ki ngā paerewa maha i te wā kotahi he tohu mō te pūkenga hangarau me te pakari o te pūnaha kounga. He māmā noa te mahi a tēnei rūri: ki te whakarato i tētahi rārangi kore e taea te whakarerekē, e taea ai te mahere me te whakatikatika i te hapa tika o tētahi tuaka mīhini hihiri.
Te Tautuhi i te Āhua Tūturu: Te Tapawhā Granite me te Tapawhā Tri Granite
Ahakoa ko te tika te mea e whakatau ana i te kounga o te nekehanga rārangi, ko te poutū (te tapawhā rānei) te mea e whakatau ana i te āhua mahi o te mīhini. Me tika te 90° o te whakawhitiwhitinga o ngā tuaka nekehanga (pērā i ngā tuaka X me Y, te tuaka Z rānei e pā ana ki te papa turanga). Ko tētahi pekanga i konei, e mōhiotia ana ko te hapa tapawhā, ka huri tika ki te hapa tūnga, ka nui ake te uaua o te whakatutuki i te whakatakotoranga āhuatanga tika.
Ko te tapawhā karāhe me te tapawhā toru karāhe ngā taputapu matua e whakamahia ana hei manatoko i tēnei koki taketake.
-
Ko te tapawhā karāhe e whakamahia ana hei manatoko i te tapawhā o ngā toki mīhini e pā ana ki te pereti mata tohutoro, hei manatoko rānei i te poutū o ngā wāhanga i te wā e huihui ana. Nā tōna āhua pakari, āhua-L, ka whakarite kia mau tonu ngā mata mahi e rua i te koki 90° kua whakamanahia.
-
Ko te tapawhā toru o te karāhe (te tapawhā matua rānei) he whirihoranga āhuahanga mata-toru ahurei, e āhei ai te tirotiro whānui ake i te āhuahanga pūtoru i roto i te anga mīhini. He tino whai hua tēnei whirihoranga mō te whakatū i ngā rohe pūtoru o ngā CMM, o ngā anga mīhini nui rānei, kia tika ai te hanga o ngā papa katoa ki a rātou anō me te turanga.
Pērā i te rūri tika, me whiwhi ēnei tapawhā i te tiwhikete Grade 00, me te hiahia kia pono ngā koki i roto i ngā hēkona-āwhata. He mahi tēnei e whakawhirinaki ana ki te pumau o te rauemi karāhe me te pūkenga kore e taea te whakakapi o ngā tohunga toi e whakamahi ana i ngā tekau tau o te wheako ki te tukanga whakapiri-ā-ringa hei whakatutuki i te āhua mata whakamutunga, he mea tino pai.
Te Pūnaha Ā-ringa: Ehara i te Kōhatu anake
Ko te mana o ēnei taputapu ine ine karāhe ehara i te mea ko ngā rauemi anake, engari ko te pūnaha katoa e tautoko ana i tā rātou tiwhikete me te hanga. E mārama ana ngā kamupene e ārahi ana i tēnei mara he ahurea te tika, ehara i te whakatakotoranga hua anake.
Ka tīmata mā ngā tohunga mahi toi. I roto i ngā awheawhe motuhake, e tino whakahaerehia ana, he maha ngā tau neke atu rānei o te wheako o ngā tohunga huri tika. He tino pūkenga ēnei tāngata ki te whakamahi i ngā pereti whakapiri motuhake me ngā matū whakakoi hei whakatika ā-ringa i ngā hapa moroiti, me te mahi tonu ki ngā ātete ka taea e ō rātou ringa te kite pai ake i te nuinga o ngā pūoko hiko. Mā ō rātou mātauranga kua kohia ka taea e rātou te whakatutuki i ngā whakaotinga mata e pana ana i ngā rohe o te papatahi me te tika, i ētahi wā ka tae ki te tauine nanometer mō te whakaotinga tino maeneene e hiahiatia ana e ngā tono kawe hau. Ko tēnei pūkenga tangata te mea matua e rerekē ai te whakatutuki i ngā whakaritenga Tohu 00 tino pakari.
Ka arotakehia, ka manatokohia hoki tēnei mahi toi. Me tino pumau te taiao hanga, me ngā rūma ma e whakahaeretia ana te āhuarangi, ngā turanga raima ārai-wiri, me ngā taputapu ine motuhake pērā i ngā ine whakawhiti laser me ngā taumata hiko e whakatikatikaina ana, e taea ana te whai i ngā taiwhanga paerewa ā-motu. Mā tēnei whakapau kaha ka noho tonu te āhuahanga whaimana o te wāhanga mai i te wā i wehe atu ai i te papa wheketere.
Ko te whakawhirinaki ki ēnei taputapu tawhito engari kua tino tika e whakaatu ana i te pono hohonu o te hangarau tino tika: ko te whai i te tere hihiri me te uaua o te rorohiko me herea tonu ki tētahi mooni āhuahanga pumau, ka taea te whakamana. Ko te rūri tika karāhe me te tika o te Grade 00, te tapawhā karāhe, me te tapawhā toru karāhe ehara i te mea nō mua; ko ngā paerewa e tika ana, e kore e taea te whakarerekē e whakamana ana i te pono o te āhuahanga o te heke mai. Mā te pupuri i te piripono ki ngā paerewa DIN, JIS, ASME, me GB, ka whakarite ngā kaihanga tohunga kia noho tonu te wahi kohatu taketake hei taputapu tino matatau e wātea ana mō te tautuhi i te pono o te āhuahanga.
