Te Whakahou i te Whai Hua o te Tapahi: Polycrystalline Cubic Boron Nitride (PCBN)
Ko ngā pereti hiato polycrystalline cubic boron nitride (PCBN) he rauemi tapahi mahi-teitei e mōhiotia ana mō tō rātou pakeke tino pai, te ātete ki te kakahu, me te kawe wera tino pai. Nā ēnei āhuatanga ka pai te PCBN mō te miihini tika o ngā rauemi uaua pēnei i te uku, te maitai whakapakeke, me te koranu pakeke. Ki te whakatauritea ki ngā taputapu tapahi tuku iho, Ngā Utauta Pcbn e tuku ana i te tika me te whai huatanga o te tapahi, e tino whakanui ana i te hua, ā, ka noho hei rawa nui i roto i te umanga whakanao.
Pereti Hikohiko PCBHe mea hanga ngā mea nei ki tētahi papa whakarewa pakari, he mea paparua ki te paura moroiti boron nitride (CBN), ā, i whakakāhia i raro i te pāmahana me te pēhanga teitei. E whakamanamana ana te CBN ki tōna pakeke tuarua i te taimana, me te pumau wera me te ātete matū e nui atu ana i te taimana, e waiho ana hei whakataetae kaha i roto i te miihini o ngā konganuku rino. Nā tēnei ka tū te PCBN hei whiringa nui i roto i ngā tono taputapu whakakoi me te tapahi.
Ko te hoahoa ahurei o ngā pereti hiato PCBN ehara i te mea ka whakarato noa i te pakeketanga me te pumau wera, engari ka whakarei ake hoki i te pakari mā roto i te papa whakarewa mārō, ka whakahaere i te tukatuka atu. He whānui te whānuitanga o ā rātou tono, e kapi ana i ngā mīhini CNC matatau, ngā taputapu mīhini aunoa katoa, me ngā raina aunoa tere-teitei. He whānui te whakamahinga o te PCBN i roto i te miihini o te maitai whakapakeke, te rino maka matao, ngā maitai taputapu, me ngā wāhanga hanga whakapakeke, ka whakakapi haere i ngā whakarewa mārō tuku iho me ngā taputapu uku, ā, ka puta hei ia o te ao matua i roto i te umanga taputapu tapahi.
1. Te Āhua Whanaketanga o Nāianei o ngā Pereti Hikohiko PCBN
Kua tino matatau ake te whanaketanga o ngā taputapu PCBN i ngā rohe pēnei i a Ūropi, Amerika Te Raki, me Hapani, kua whakatūria he pūnaha hangarau pakari. Kei te piki haere te rongonui o ngā hua mā te kanorau, te arotau kounga, me te mahi ōrite. Ko ngā pereti hiato PCBN mai i tāwāhi he pumau tonu i ngā diameter neke atu i te 50mm, ā, ko ngā hua a Element Six he 57mm me te 101.6mm o ngā tinana CBN parakore (AMB90) ngā diameter, me te pupuri i te rerekētanga o te kakahu me te mahi wera i roto i te 30% mō te ōritetanga tino pai. Ka whakaratohia e DI me Sumitomo ngā whakatakotoranga o te 50.8mm, 58mm, me te 64mm.
Kua angitu a Boreas ki te whakawhanake i ngā pereti hiato PCBN 64mm te whānui i muri i ngā tau rangahau, me ngā rahi matūriki mai i te 2μm ki te 15μm. Neke atu i te 20 ngā momo otinga kua whakaritea kia tutuki ai ngā hiahia miihini motuhake. Mā te whiriwhiri i ngā pereti hiato PCBN a Boreas, ka kite koe i te pikinga nui o te pai o te tapahi me te kounga!
