Ko ngā taputapu tapahi kāpira sima, inā koa ko ngā taputapu kāpira sima tātai, ko ngā hua matua o ngā taputapu miihini CNC. Mai i te tekau tau atu i 1980, kua whānui haere te whānuitanga o ngā taputapu kāpira sima totoka me ngā taputapu tātai, tae atu ki ngā taputapu whakauru puta noa i ngā momo taputapu tapahi. I roto i ēnei, kua whanake ngā taputapu kāpira sima tātai mai i ngā taputapu huri noa me ngā taputapu mira mata ki te whakauru i te whānuitanga o ngā taputapu tika, matatini, me te hanga.
(1) Ngā Momo Utauta Karāpire Simeni
I runga i te hanganga matū matua, ka taea te whakarōpū i ngā warowaiha sima ki ngā wāhanga matua e rua: ngā warowaiha sima e ahu mai ana i te warowaiha tungsten me te warowaiha sima e ahu mai ana i te titanium carbonitride (TiC(N)).
E toru ngā momo o ngā kāpira sima e hangai ana ki te kāpira tungsten:
Tungsten-cobalt (YG)
Tungsten-cobalt-titanium (YT)
Ko ērā he kāpira onge kua tāpirihia (YW)
He painga, he ngoikoretanga anō hoki tō ia momo. Ko ngā wāhanga matua ko te tungsten carbide (WC), te titanium carbide (TiC), te tantalum carbide (TaC), te niobium carbide (NbC), me ētahi atu, ko te cobalt (Co) te mea e whakamahia whānuitia ana hei here whakarewa.
Ko ngā waroiti sima e hangai ana ki te titanium carbonitride he mea hanga nui mai i te TiC, ā, ko ētahi momo he waroiti tāpiri, he nitride rānei. Ko ngā mea e herea ana te konganuku e whakamahia whānuitia ana ko te molybdenum (Mo) me te nickel (Ni).
E toru ngā wāhanga o te International Organization for Standardization (ISO) mō ngā warowaiha sima e whakamahia ana mō te tapahi:
Akomanga K (K10 ki te K40): He rite ki te akomanga YG o Haina (ko te WC-Co te nuinga).
Akomanga P (P01 ki P50): He rite ki te akomanga YT o Haina (ko te nuinga ko WC-TiC-Co).
Akomanga M (M10 ki te M40): He rite ki te akomanga YW o Haina (ko te nuinga ko WC-TiC-TaC(NbC)-Co).
Ko ia tohu e tohuhia ana e ngā tau mai i te 01 ki te 50, e tohu ana i te whānuitanga o ngā koranu mai i te pakeketanga teitei ki te pakari mōrahi.
(2) Ngā Āhuatanga Mahi o ngā Utauta Karāpire Simeni
① Teitei o te Pakari
Ka hangaia ngā taputapu kāpira sima mā te mahi whakarewa paura, e whakakotahi ana i ngā kāpira he pakeke teitei me ngā ira rewa (e kiia nei ko te wāhanga mārō) me ngā mea here konganuku (e kiia nei ko te wāhanga here). Kei waenganui i te 89 ki te 93 HRA te pakeke, he nui ake i te maitai tere-rahi. I te 540°C, kei waenganui i te 82 me te 87 HRA te pakeke, he rite ki te pakeke pāmahana-rūma o te maitai tere-rahi (83–86 HRA). Ka rerekē te pakeke o te kāpira sima i runga i te momo, te rahinga, me te rahi o te witi o ngā kāpira, tae atu ki te ihirangi o te wāhanga here konganuku. I te nuinga o te wā, ka heke te pakeke i te pikinga ake o te ihirangi wāhanga konganuku here. Mō te ihirangi wāhanga here kotahi, he nui ake te pakeke o ngā koranu YT i ngā koranu YG, ā, ko ngā koranu me te TaC, NbC rānei kua tāpirihia he pakeke pāmahana-rahi pai ake.
② Te Kaha me te Pakari o te Piko
Ko te kaha piko o ngā warowaiha sima e whakamahia whānuitia ana kei waenga i te 900 ki te 1500 MPa. Ko te nui ake o te ihirangi honohono whakarewa ka hua ake te kaha piko nui ake. Ina rite tonu te ihirangi here, ka whakaatu ngā koranu YG (WC-Co) i te kaha teitei ake i ngā koranu YT (WC-TiC-Co), ā, ka heke te kaha i te pikinga ake o te ihirangi TiC. He rauemi pakarukaru te warowaiha sima, ā, ko tōna pakari pānga i te pāmahana rūma he 1/30 ki te 1/8 noa iho i te pakari o te maitai tere-rahi.
(3) Ngā Whakamahinga o ngā Utauta Karāpire Sima Noa
Ngā koranu YG:E whakamahia ana mō te miihini i te rino maka, ngā konganuku kore-ferrous, me ngā rauemi kore-whakarewa. Ko ngā waro sima pai-kikokiko (hei tauira, YG3X, YG6X) he nui ake te pakeke me te ātete ki te kakahu i ngā momo kākano-waenga me te nui o te cobalt. He pai ēnei mō te tukatuka i ngā rauemi motuhake pēnei i te rino maka mārō, te maitai kore waikura austenitic, ngā koranu ātete-wera, ngā koranu titanium, te parahi mārō, me ngā rauemi ārai ātete-kakahu.
Ngā koranu YT:He mea rongonui mō tōna pakeketanga teitei, tōna ātete wera pai rawa atu, me tōna pakeketanga me tōna kaha pēhitanga i ngā pāmahana teitei ki te whakataurite ki ngā koranu YG, me te ātete pai ki te waikura. Mēnā he nui te ātete wera me te kakahu e hiahiatia ana e ngā taputapu, e taunakihia ana ngā momo he nui ake te ihirangi TiC. He pai ngā koranu YT mō te miihini i ngā rauemi kirihou pēnei i te maitai engari kāore e pai mō ngā koranu titanium, ngā koranu silicon-konumohe rānei.
Ngā koranu YW:Ka whakakotahi i ngā āhuatanga o ngā koranu YG me YT, ka tukuna he mahi tino pai. He maha ngā whakamahinga, ā, ka taea te whakamahi mō te miihini i te maitai, te rino maka, me ngā konganuku kore-ferrous. Mā te whakanui tika i te ihirangi cobalt, ka taea e ngā koranu YW te whakatutuki i te kaha teitei, ka pai ai mō te miihini taratara me te tapahi aukati i ngā rauemi uaua ki te miihini.
