Ehara te tapahi i te mahi uaua: Whakamahia ngā mata kani whitiki carbide hei whakatutuki i te tukatuka atamai ake.
I te wā e kani ana i ngā rauemi uaua ki te tukatuka (pērā i ngā koranu titanium, te maitai kore waikura, ngā koranu ātete-wera me ngā konganuku whakapakeke-mata), kua whakamahia whānuitia ngā mata kani whitiki niho karāhe nā te mea he tino pai.tapahite whai huatanga me te pakari. I ngā tau tata nei, kua piki haere te maha o ngā kaiwhakamahi kua tīmata ki te whakamahi i ēnei ki te tukatuka i ngā rauemi noa, ā, kua kitea he tere te tere tapahi, he pai te āhua o te mata, ā, ka taea te whakanui ake i te roa o te mahi mā te 20% ki te whakataurite ki ngā mata kani whakarewa rua tuku iho.
1. Hanganga me te āhua o ngā niho
Ko ngā āhua niho noa o ngā mata kani poroporo karāhe ko te tapahi niho-toru me te huri poroporo. I roto i ēnei, ko te āhua niho tapahi niho-toru he mea whakamahi i te hoahoa koki rake pai, e āwhina ana ki te "ngau" tere i te rauemi me te hanga maramara i roto i ngā rauemi kaha-teitei, pakeke-teitei rānei, ā, he pai mō ngā āhuatanga whakaputa whai hua. I te tukatuka i ngā rauemi mata-uaua (pēnei i ngā tokotoko rango, i ngā toki waipēhi rānei), he pai ake te whakamahi i te āhua niho koki rake kino. Ka āwhina tēnei hanganga ki te "pana" i te paparanga mata mārō i raro i ngā āhuatanga wera nui, kia maeneene ai te tapahi.
Mō ngā rauemi whakakoi pērā i te whakarewakonumohe, he pai ake ngā mata kani roopu he whānui te niho me te hoahoa awaawa tapahi whānui, ka taea ai te whakaiti i te kaha piri o te rauemi i te tuara o te mata kani, me te whakaroa i te roa o te ora o te taputapu.
2. Ngā momo mata kani rerekē me ō rātou whānuitanga e tika ana
· Ngā rauemi iti te whānui (<152mm): He pai mō ngā mata kani carbide he hanganga niho-toru me te āhua niho koki rake pai, he pai te tapahi me te urutau ki ngā rauemi.
· Ngā rauemi whānui nui: E taunakihia ana kia whakamahia ngā mata kani he hoahoa maha-mata, e huri ana kia rima ngā mata tapahi i ia pito niho hei whakapai ake i te kaha tapahi me te tere tango rauemi.
· Taputapu whakapakeke mata: Me whiriwhiri te koki rake kino me ngā mata kani niho-toru, ka taea te tapahi i te pāmahana teitei me te tango tere i ngā maramara, ā, ka tapahia pai te anga mārō o waho.
· Ngā konganuku kore-whakarewa me te konumohe whakarewa: He pai mō ngā mata kani he hoahoa niho whānui te kohao hei karo i te piri o te awaawa me te whakaiti i te pakaru wawe.
· Ngā āhuatanga tapahi whānui: E taunakihia ana kia whakamahia ngā mata kani whitiki waro whānui he āhua niho koki rake pai iti, he āhua niho koretake rānei, e tika ana mō ngā momo āhua rauemi me ngā whakaritenga tapahi.
3. Te awe o te momo niho ki te kounga tapahi
He rerekē ngā momo niho, ā, he rerekē ngā tikanga hanga maramara. Hei tauira, e whakamahia ana e tētahi hoahoa ngā niho e whā hei hanga i ngā maramara e whitu. I te wā e tapahia ana, ka tohaina ōritetia te kawenga e ia niho, ā, ka āwhina tēnei ki te whiwhi i tētahi mata tapahi maeneene ake, tika ake hoki. Ko tētahi atu hoahoa e whakamahi ana i tētahi hanganga niho-toru hei tapahi i ngā maramara e rima. Ahakoa he paku teitei ake te taratara o te mata, he tere ake te tere tapahi, he mea e tika ana mō ngā āhuatanga tukatuka e whakatairangatia ana te whai huatanga.
4. Te paninga me te whakamatao
Ka tāpirihia ētahi mata kani karāhe ki ngā paninga tāpiri, pērā i te konukōrete tāitaniuma (TiN) me te konukōrete tāitaniuma konumohe (AlTiN), hei whakapai ake i te ātete ki te kakahu me te ātete ki te wera, ā, he pai hoki mō ngā mahi tere me te whāngai tere. He mea tika kia mōhiotia he pai ngā paninga rerekē mō ngā āhuatanga mahi rerekē, ā, me whai whakaaro whānuitia mēnā me whakamahi paninga i runga i ngā āhuatanga tono motuhake.
