Mā te miihini CNC tika me te whakarewa whakarewa ka puta ngā wāhanga tino nui mō ngā taputapu ahumahi, mai i ngā whare me ngā hononga ritenga ki ngā wāhanga taputapu mīhini tauine nui e hiahia ana kia inehia ngā āheinga ki ngā maikiromita.
Kei muri i ia mīhini taputapu tika, i ia karetao ahumahi, i ia pūnaha waipēhi, i ia raina whakaputa aunoa rānei, he kohinga wāhanga whakarewa kua mīhinihia hei whakatau mēnā ka mahi te taputapu kia rite ki ngā whakaritenga. Ngā taputapu, ngā pou, ngā whare, ngā whāriki, me ngā hononga miihini motuhake — me hanga ia mea ki ngā taunga e whakarite ana i te taunga tika, te mahi maeneene, me te roa o te ora ratonga. Mō ngā tono tino uaua, ka tohua ngā taunga ki roto i ngā maikiromita, ehara i te mirimita, ā, me kaha ngā tukanga hanga ki te tuku i aua taunga kia rite tonu, wāhanga i muri i te wāhanga.
Mīhini CNC Tika: Te Pūkenga me te Whānuitanga
He maha ngā tukanga o te miihini CNC (Rorohiko Mana Tau) hou, e hāngai ana ki ia tukanga ki ngā āhuahanga me ngā ātete rerekē:
Ko te mira CNC te tino mahi o te miihini tika, ka taea te whakaputa i ngā āhua matatini e toru-ahu mai i te rakau pae, te pereti, ngā whakarewa me ngā mea whakarewa kua oti te hanga. Ka taea e ngā pokapū miihini maha-tuaka — inā koa ngā mīhini 5-tuaka — te whakaputa i ngā wāhanga tino uaua i roto i te whakatakotoranga kotahi, ka whakaiti i ngā hapa tūnga tāpiri e puta mai ana i ngā whakatakotoranga maha.
Ka whakamahia te hurihanga CNC (ngā mahi mīhini huri) mō ngā wāhanga hurihuri: ngā pou, ngā whare, ngā hononga, me tetahi wāhanga he ōrite te āhua o te porotaka. Ka taea e ngā mīhini hurihanga CNC tino tika me ngā taputapu ora te whakaputa i ngā wāhanga hurihuri matatini me ngā āhuatanga mira i roto i te mahi kotahi.
Ka whai te huri CNC i te miihini taratara hei whakatutuki i ngā ātete kikī whakamutunga me ngā whakaotinga mata e hiahiatia ana mō ngā wāhanga tino tika. Ko te huri mata, te huri porotaka, me te huri kore pokapū ngā mahi tino noa. Mō ngā ātete kikī rawa — i raro i te 5 μm — ka taea te tohu i te huri whāngai-ngoioi, te huri hiko rānei i roto i te tukanga.
Mā te mīhini tuaka-maha (tuaka-4 me te tuaka-5) ka taea te whakaputa i ngā āhuahanga uaua e kore e taea, e hiahiatia ana rānei he maha ngā whakatakotoranga i runga i ngā mīhini māmā ake. Mō ngā wāhanga rererangi me ngā taputapu hauora he koki whakakotahi me ngā mata whakairo, ko te mīhini tuaka-5 te tikanga hanga mahi anake.
Ngā Manawanui me ō Rātou Tikanga Whaitake
Ina tohua ngā tūponotanga mōngā wāhanga mīhini tika, me mārama ngā kaihangarau ki ngā mea ka taea te whakatutuki, me ngā mea e tohu ana i te kaha hou:
Te tika paerewa (±0.01 mm ki te ±0.05 mm): Ka taea te whakatutuki i runga i ngā taputapu CNC e tiakina pai ana, kāore he tukanga motuhake. He pai mō te nuinga o ngā huihuinga mīhini ina taea e ngā wāhanga te whakauru i ētahi rerekētanga ā-ahu.
Teitei te tika (±0.001 mm ki te ±0.01 mm): Me whai taputapu miihini tino tika, ngā taiao toa whakahaere, me te ine i roto i te tukanga, te tirotiro i muri i te tukanga rānei. He mea noa mō ngā tono taputapu me te peera tino tika.
Tino tika (i raro i te ±0.001 mm): Me whai taputapu motuhake (ngā mīhini CNC tino tika, ngā mīhini huri rānei), te whakahaere taiao (te pumau o te wera, te wehe i te wiri), me ngā pūnaha ine taumata ine. Ka tutukihia e ngā tohunga i roto i te miihini tino tika mō ngā tono pēnei i ngā pūnaha whatu me ngā wāhanga tino tika.
Me tohu e ngā kaihoko ngā taunga tino pakari e hiahiatia ana mō te mahi, kaua e tino pakari ake. Mā te nui rawa o ngā taunga ka piki ake te utu, engari kāore he painga, ā, ka uaua pea te kimi rauemi, ka nui rawa rānei te utu.
Ngā Rauemi Noa mō ngā Wāhanga Mīhini Tika
Ko te rauemi i tīpakohia mō tētahi wāhanga mīhini tino tika ka whakatauhia e ngā whakaritenga tono — te kaha, te ātete ki te kakahu, te ātete ki te waikura, ngā āhuatanga wera, te taumaha, me te utu:
Konumohe koranu (6061, 7075, 2024): He tino pai te mahi miihini, he pai te ōwehenga kaha-ki-taumaha, he utu taurite. Ko te 6061 te whiringa whānui e whakamahia whānuitia ana; he kaha ake te 7075 mō ngā mahi rererangi me ngā mahi hōia.
Kowiri tira (303, 304, 316, 440C): He ātete pai ki te waikura (ina koa ko te 316), he kaha pai, he ngāwari ki te miihini. Ko te 303 te kowiri tira tino ngāwari ki te miihini engari he iti ake te ātete ki te waikura. Ka whakamahia te 440C mō ngā mahi pakeke pērā i ngā wāhanga peera.
Ngā maitai koranu (4140, 4340, ngā maitai taputapu): He kaha nui, he pakari hoki, he ātete pai ki te kakahu. Me whakamahana kia pai ai ngā āhuatanga. Whakamahia mō ngā taputapu, ngā pou, me ngā wāhanga hanganga e hiahia ana kia kaha nui.
Ngā koranu titanium (Ti-6Al-4V): He ōwehenga kaha-ki-taumaha tino pai, he ātete waikura tino pai, he hototahi ki te koiora. He uaua ki te mīhini nā te iti o te kawe wera — me whai taputapu me ngā rautaki mīhini motuhake.
Parahi me te parahi: He pai te ngāwari ki te miihini, he tino ātete ki te kakahu (he parahi te mea nui), he pai ngā āhuatanga o te peera. Whakamahia mō ngā pū, ngā wāhanga peera, me ngā taputapu whakapaipai.
Rino maka (rino hina, rino ngāwari): He tino pai te whakamākū, he pai te ātete ki te kakahu, he iti te utu mō ngā wāhanga nunui. He tino pakari te rino ngāwari ki te whakataurite ki te rino hina.
Te Maka Whakarewa mō ngā Wāhanga Nui, Uaua hoki
Mō ngā wāhanga he nui rawa, he uaua rawa rānei ki te mīhini mai i te rakau paera, i ngā mea hanga rānei, ko te whakarewa whakarewa te tikanga hanga tika:
Ko te whakarewa onepu te tikanga whakarewa tino maha ngā whakamahinga me te utu iti mō ngā wāhanga nui me ngā rahinga whakaputa iti ki te taurite. Ko ngā ātete he ±1-2 mm te nuinga, me ngā whakaotinga mata kei roto i te awhe 200-400 μin Ra. He pai mō ngā whare, ngā whāriki nui, me ngā hanganga taputapu mīhini.
Mā te whakarewanga haumitanga (te whakarewanga ware pi ngaro) ka puta he wāhanga he tino pai te mutunga o te mata me te tika o ngā āhuatanga, ko te tikanga he ±0.5 mm, he pai ake rānei. He pai mō ngā āhuahanga uaua me ngā rahinga whakaputa ina taea te whakamāori i ngā utu taputapu.
He tino pai te whakahaere i ngā āhuatanga me te whakaotinga mata o te whakarewatanga mate (mō ngā koranu konumohe me te konutea) mō te whakaputanga nui. Ka taea te whakatutuki i ngā ātete o te ±0.05 mm. E whakamahia ana mō ngā whare me ngā wāhanga hanganga i roto i ngā hua kaihoko me ngā tono motuka.
Ko te whakarewanga tika e whakauru ana i ngā tikanga whakarewa motuhake (tae atu ki te whakarewanga tohanga me te whakarewanga tonu) e whakaputa ana i ngā wāhanga he kaha ake te mauri me ngā āhuatanga rauemi pai ake i te whakarewanga onepu tikanga. E whakamahia ana mō ngā mowhiti nui, ngā ngongo, me ngā hanganga porotaka e hiahia ana ki te whakahaere i ngā āhuatanga tika.
Mō ngā tono tino tika, ka mīhinihia ngā wāhanga whakarewa puta noa i te mata (ka mīhinihia ki te CNC ngā mata katoa) kia tutuki ai ngā āheinga whakamutunga me ngā whakaotinga mata e hiahiatia ana.

Ngā Pātai Auau
He aha te manawanui tino pātata e taea ana te whakatutuki i roto i te miihini CNC?
Ka taea e ngā taputapu CNC e tiakina pai ana i roto i ngā taiao whakahaeretia te whakatutuki i ngā ātete o te ±0.005 mm (5 μm) i ia wā. Ka taea e ngā pokapū miihini tino tika te whakatutuki i ngā ātete i raro i te ±0.001 mm (1 μm) mō ngā āhuatanga matua. Heoi, me tohu noa ngā ātete kikī i ngā wā e tika ana te mahi.
He aha te mutunga mata ka taea te whakatutuki i ngā wāhanga mīhini CNC?
Ko te mira CNC te tikanga ka tutuki te Ra 0.8-3.2 μm i te wā i mirahia ai. Ka taea e te mira tika te whakatutuki i te Ra 0.1-0.4 μm. Mā te mira me te whakaotinga nui ka taea te whakatutuki i te Ra i raro i te 0.05 μm mō ngā mahi hiri me te whāriki tino uaua.
