He aha ngā wero o te hurihanga CNC o ngā wāhanga kowiri tira?

2026-01-12

Te tika Te hurihanga CNC e whakamahia ana mō te miihini i ngā wāhanga hurihuri ka taea te piri pono ki runga i te mīhini hurihuri. Ko ngā mīhini hurihuri CNC e tohuhia ana e te pakari teitei, te hanga tika, me te whakatakotoranga taputapu tika. Ka taea e rātou te utu taputapu ā-ringa, ā-aunoa rānei, kia tika, kia taea ai te miihini i ngā wāhanga me ngā whakaritenga tika o te mīhini hurihuri. Heoi anō, ko te nekehanga taputapu i roto i te hurihuri e whakahaerehia ana e te tau ka tutuki mā roto i ngā pūnaha whakawhiti me te taraiwa servo tino tika. I te wa e miihini ana i ngā pewa, i ētahi atu mata piko rānei, ka puta i tēnei tikanga ngā āhua e tino rite ana ki ngā whakaritenga āhuahanga o ngā tuhi hoahoa ki te whakataurite ki ngā mīhini hurihuri tārua.

Ko te maitai kore waikura, kei roto ko te 16%–18% te chromium, e kiia ana he maitai kore waikura ātete-waikawa, he maitai kore waikura ātete-waikura rānei. He pai tōna ātete ki te waikura i roto i ngā taiao hauhautanga, i ngā taiao waikura pakupaku rānei, ā, ka mau tonu tōna kaha i ngā pāmahana teitei (>450°C). E mōhiotia ana mō tōna ātete ki te waikura, tōna ngāwari ki te hanga, tōna ngāwari ki te urutau, me tōna pakari kaha puta noa i te whānuitanga o te pāmahana, e whakamahia whānuitia ana te maitai kore waikura i roto i ngā ahumahi taumaha, ngā ahumahi māmā, me ngā hua o ia rā.

Āhea Mīhini CNC mō ngā wāhanga kowiri tira, ko ngā whāinga ko te tere, te tika, me te tino tika. Heoi, he maha ngā wero ka tūtakihia i roto i te tukanga. Kei raro nei, ka tātarihia e mātou ngā uauatanga matua ka puta ake i roto i te hurihanga CNC o ngā wāhanga kowiri tira.

1.      Te Kaha me te Pakari Wera Nui
Nā te kaha wera me te pakari o te maitai kore waikura, he uaua ki te tapahi tere-teitei, ā, ka pā tika tēnei ki te miihini CNC. He wero nui tēnei i roto i te tapahi CNC o te maitai kore waikura. Ahakoa kāore ngā maitai kore waikura austenitic me martensitic e whakaatu ana i te pakeke teitei, i te kaha kume rānei—he rite ki te maitai waro Nama 40—he nui ake te roa, te whakaiti i te horahanga, me te uara pānga. Hei tauira, ko te roa o te 1Cr18Ni9Ti he rite ki te 210% o te maitai Nama 40. Ka hua ake tēnei he uaua ki te pakaru maramara i te wā e tere-rahi ana. Te tapahi CNC, me te nui o te whakapaunga pūngao nā te tapahi i whakarerekē te āhua.

2.      Te Whakapakari Mahi me te Piripiri
He ngāwari te kowiri tira ki te whakapakeke i te mahi me te piri maramara, ā, ko te ngoikore o te kawe wera ka uaua ake te tukanga tapahi. I te wā e huri tere ana te CNC, ka pāngia te kowiri tira e te whakapakeke mahi. Ko te putanga mai o te rauemi mahi e te pito taputapu ka puta he rerekētanga i roto i te rohe tapahi, ka puta he paheke o roto i te kirikiri, he hē o te whatunga, me te whakakīkī hanganga moroiti. Ka taea e tēnei te whakanui ake i te pakeke tapahi mā te 2-3 ngā wā, ā, i ētahi wā ka eke te paparanga whakapakeke ki ngā rau maikiromita te hohonu. Hei tāpiri, ko te piri kaha me te ngoikore o te kawe wera o ngā maramara kowiri tira ka whai wāhi ki te hanganga taha i te pito taputapu me te mata tapahi, ka whakanui ake i te wiri i te wā e miihini ana, ka tere ake te mau o te taputapu.

3.      Ngā Take Mīhini Miro
Ko ngā raruraru noa ko te koretake o te mata o ngā miro me te pakaru nui o ngā taputapu. I te wā e miro ana i te maitai kore waikura CNC, ka puta pinepine ngā raruraru noa pēnei i te koretake o te mata o te miro, ngā tauira rite ki te unahi ika, me te ngau o te taputapu. Ko te take matua o ēnei ko te iti rawa o te koki whakawātea i ngā taha e rua o te taputapu miro, ka nui ake te waku ki te mata miro, ka heke hoki te kounga o te miihini. Heoi anō, kāore e taea te wareware i te pakaru o te taputapu, nā te mea ka whakarerekē i ngā koki rake me te whakawātea, ka piki ake te kaha tapahi, te wiri, me te heke o te mata miihini.

4.      Ngā Take Utauta me ngā Utauta Mīhini
Ka puta te wiri i te kore e ranea te pakari me te kore tika o te taputapu mīhini, ā, ka pā kino ki te kounga o te mīhini. He mea nui anō hoki te pakari o te taputapu mīhini me te pūnaha taputapu. Ko ngā raruraru pēnei i te kore e mau te taputapu miro, te iri nui o te taputapu, te kore e ranea te pakari o te kaipupuri taputapu, me te kore tika o te taputapu mīhini ka puta te wiri, ā, ka whakararu i te kounga o te mata o te miro. Nō reira, i te wā e whakamahia ana, he mea nui kia mau te mīhini, te taputapu, me te wāhanga mahi, me te āta whakatikatika i te teitei o te pito taputapu kia kore ai e ngau te taputapu.

Ahakoa mīhini CNC tino tika Ahakoa he pai te taurite o ngā āhuatanga whai hua o te kowiri tira, he maha ngā wero kei roto. He tino ngāwari te whakapakeke i ngā kowiri tira austenitic i te wā e mahi ana i te mīhini, ka piki ake te pakeketanga. Mena kāore te mīhini i te mōhio ki te tukatuka kowiri tira, ka tere ake te pakaru o ngā taputapu, ā, ka pā kino ki te kounga o te hua kua oti.

Hei tāpiri atu, he iti noa te kawe wera o te maitai kore waikura, ā, ka nui haere te wera i roto i te rohe tapahi. Ki te kore e tika te whakamatao me ngā tawhā tapahi tika, ka piki ake te pāmahana kia nui ai te pāwera o te maitai kore waikura. I runga i te whakamahinga e hiahiatia ana o te wāhanga maitai kore waikura, ka hua ake pea ngā take pēnei i te waikura intergranular me te pakaru o te waikura ahotea.

Ahakoa ēnei wero, ka taea e ngā kaimahi mīhini mohio te whakaputa i te maitai kore waikura kounga teitei me te pono. Ngā wāhanga CNC mena ka whakamahia ngā taputapu me ngā taputapu e tika ana, me ngā mahi miihini kua tino arotauhia.
