Ngā Pūrongo - Me pēhea te hanga i ngā niho tika mō tō mata kani

I roto i te ao tapahi ahumahi, he maha ngā wā ka pohehetia ngā mata kani he mea pau noa. Heoi, ki ngā miihini mohio, ki ngā kaiwhakahaere whakaputa rānei, he taputapu tino tika te hoahoa o te mata kani. Ko te kounga o te pānga tapahi ka whakawhirinaki ki te rerekētanga o te āhua o te niho e rua ki te toru nekehanga noa iho, ka taea ai te whati nui o te mata kani, te hua rānei he mata tapahi maeneene rite ki te whakaata.

I tēnei wā ka keri mātou ki ngā āhuatanga ā-tinana o ngā koki niho kani, ka wetewete hoki i te pānga o ngā āhua niho motuhake ki te hanga wera, te kawenga maramara me te kounga tapahi mō ngā momo rauemi matua e toru: ngā konganuku rino (tapahi maroke), te rakau me ngā mea hanga whare.

Te Anatomi o te Niho

I mua i te tātari i ngā tono motuhake, me whakarite e tātou ā tātou kupu mō ngā taha koki matua e toru e tautuhi ana i te mahi tapahi.

Ko te Koki Rake te koki o te mata o te niho e pā ana ki te rārangi radial e kumea ana mai i waenganui o te mata ki te pito o te niho.

Mahi:Ka whakatau i te "kaha" o te tapahi. Ka whakatau i te koki o te papa kutikuti—te koki e whakapohehetia ai te rauemi, e wehea ai hoki i te mea mahi.

Te Ture Matua:He iti ake te mana e hiahiatia ana mō ngā koki pai ake, engari he taratara ake te āhua, he iti ake te pakari o te taha. He nui ake te hōpaika e hiahiatia ana mō ngā koki kino, engari he pai ake te mana whakahaere me te kaha o te taha.

Te Koki Ātea (Koki Whakaiti) —β

Koinei te kōpiko kei runga i te niho e matara atu ana i te mata tapahi.

Ko tā rātou mahi he aukati i te mirimiri o ngā pito carbide ki te rauemi i tapahia e koe.

Anei te utu:Ki te tino pari te koki, ka pakarukaru ngā pito o ngā niho, ā, ka kore he tautoko, ka pakarukaru. Ki te papaku rawa, ka nui rawa te wera ka puta mai i te waku, ka horapa te wera, ā, ka tahuna te mea mahi.

Te Āteatanga o te taha (Radial)

Ka whakaitihia te niho e tēnei koki i ngā taha mai i mua ki muri.

Ka whakaiti i te waku i waenga i ngā taha o ngā niho me ngā pakitara o te kerf (te mokowā tapahi). Mō ngā mahi tapahi maroke kāore he hinu whakahinuhinu hei whakamatao i ngā taha o ngā niho, he mea tino nui tēnei koki hei aukati i te hanga o te wera.

Ngā Konganuku Ferrous (Te Kani Makariri Tapahi Maroke)

Arotahi: Te Whakahaere Wera me te Ātete Pānga

Ko ngā kani matao maroke-tapahia (he mea whakauru ki ngā pito cermet, ki ngā pito carbide pania rānei) te wāhanga hangarau tino uaua ki te hoahoa. Ā, anei te whāinga rerekē: e hiahia ana tātou ki te whakaputa wera, engari me whakakore tonu e tātou.

I te wā e tapahi maroke ana, ka puta te wera mai i te āhua kirihou o te maitai. Me whakawhiti e te āhua o te taputapu te 80% ki te 90% o taua wera ki ngā maramara—mā tēnei, ka noho mātao te mata me te mea mahi. Koinei tonu te mahi a te mātāpono "tapahi makariri".

Te Āhuahanga o te "Cold Cut"

I te wā e tapahi ana i te maitai ngawari, ka whakamahia e mātou te kōtaha huri-toru-maramara (TCG). Engari ka rerekē te koki i runga i te hanganga moroiti o te maitai.

Ngā Whakamahinga Pakitara Angiangi (Ngongo, Rino Koki, Hongere)

Koki Rake: Pai (+5° ki te +10°)

Koki Ātea: 10° ki te $12°

Whakaaroaro:Mā te paku teitei ake o te āputa ka āwhina i te niho kia puta ma te niho i te tapahi, me te kore e tō ki te taratara e hangaia ana i te taha o roto o te ngongo.

Ngā Whakamahinga Totoka (He Huka Pae, He Pereti Matotoru)

Koki Rake: Kore ki te Iti Pai 0° ki te +3°

Te Ahupūngao:Ina tapahia te maitai totoka, ka roa ake te piri o te niho ki te rauemi, ka puta he kawenga pānga tonu. Nā te koki pai koi ka waiho te pito carbide kia kore e tautokona, kia ngoikore hoki. AKore te koki Rakeka tukuna whakamuri ngā kaha tapahi ki roto i te tinana o te mata, ka whakamahia te kaha pēhi o te kāpia (he teitei) kaua ki tōna kaha kutikuti (he iti iho).

Koki Ātea: 8°

Whakaaroaro:Mā te koki ātea iti ka nui ake te "kiko" i muri i te mata tapahi, ka mahi hei totohu wera me te tautoko hanganga.

Kowiri tira (Te Wero Whakapakari Mahi)

Koki Rake: 0°ki te +5°
Whakaaro Motuhake:Ka "pakari" te maitai kore waikura (pērā i te SUS304) mēnā ka mirimirihia. Ko te matametapahia, kaua e paheke. Ahakoa he kaha te rake kore, he maha tonu ngā wā ka hiahiatia he rahi akeKoki Ātea (12°)i te mea e whakamahia ana mō te maitai ngawari. Mā tēnei ka kore te tuara o te niho e pā ki te rauemi i muri i te tapahi, ka "hoki whakamuri" anō hoki nā tōna ngāwari.

Ngā tono mahi rakau

Arotahi: Te Ahunga o te Wiri me te Motuka o te Muka

He rauemi anisotropic te rakau—he rerekē ōna āhuatanga ā-tinana i runga i te ahunga o te kaha e pā ana ki te kakano. Nō reira, me urutau te āhua o te mata kani ki te kakano.

A. Haehae (Te Tapahi ki te Kakano)

He mahi whakairo te haehae. Ko te whāinga he hiki ake i ngā miro muka roa kia kore e araia.
- Koki Rake: Teitei Pai (+20°ki te +25°)
- Āhuahanga: Huri Papatahi (FTG)
- Te Ahupūngao:He rite te mahi a te koki matau teitei ki te papa ringa, e tere ana te tango rauemi. Mā tēnei koki kaha ka kumea te rakau ki roto i te mata. Ahakoa ka taea te tere o te whāngai (he mea nui mō ngā mira kani), ka waiho he mata taratara.
- Te Take o te Korokoro:Me hohonu, me nui hoki te "Kau" (te awaawa i waenganui i ngā niho). Ka nui ngā maramara ka puta mai i ngā muka kakano roa; ki te iti rawa te kau, ka pēhia te puehu, ka puta he waku, ka tahuna te rakau (me te mata).
B. Te Tapahi Whakawhiti (Te Tapahi i te Witi)

Ko te tapahi whakawhiti me tapahi i ngā muka e poutū ana ki te tapahi. Ki te whakamahi koe i te mata haehae (FTG) ki konei, ka "pahū" ka pakaru rānei te rakau i te taha putanga.
- Koki Rake: Pai Waenga (+10°ki te +15°)
- Āhuahanga: Te Ahua Whakamuri o te Runga (ATB) me te Ahua Hi-ATB rānei
- Te Ahupūngao:Ka whakapikohia ngā niho kia rite ki ngā maripi ngā mata i ngā taha e whakawhiti ana. Ka tapahia ngā muka ki te taha maui me te taha matau o te kerf.i mua ite tango i te rauemi o waenganui. Ko te koki rake o raro (10°ki te 20°) ka whakaroa i te "hopu" o te mata, kia maeneene ake ai te mahi kutikuti e waiho ana he kiko mutunga kua orohia.

Kore-Wero me ngā Hikohiko

Arotahi: Haumaru me te Ātete ki te Waro

A. Konumohe me ngā konganuku kore-ferrous

He ngohengohe te konumohe, he ngāwari te tango, ā, he iti te ira rewa. He "kapia" tōna, ā, ka ārai i ngā niho o te mata.
- Koki Rake: Kino (-5)°ki te -6°)
- Āhuahanga: TCG
- Te Ahupūngao o te Haumaru:Ki te whakamahia he koki matau pai (pērā i te mata rakau) ki te konumohe, ka "piki" te mata ki runga i te rauemi. I roto i te kani tapahi ā-ringa, ka taea e tēnei te kukume kaha i te kakau kani ki raro, te maka rānei i te mea mahi. ARake KinoKa hurihia e te koki te kaha: ka panaia te rauemiatumai i te mata me te taiapa o muri, kia mōhio ai he tapahi haumaru, he tapahi whakahaeretia hoki.
- Whakahinuhinu:He rerekē tēnei i te tapahi maroke o te maitai, me whakahinuhinu te konumohe kia kore ai e honoa ngā maramara ki te korokoro.
B. Ngā Hanganga Hiko (Raina, Meramina, Sima Muka)
- Koki Rake: Kino (-2°ki te -5°)
- Te Ahupūngao:He papa matotoru, he rite ki te karāhe te papa o ngā rauemi pēnei i te Melamine, ā, he papa matotoru anō hoki tōna e pania ana ki runga. Mā te matau pai ka hiki ake te rauemi, ka pakarukaru te mata pakarukaru.Matau Kinoka pēhi i te rauemi ki raro i te wā e tapahia ana, ka pēhi i te paparanga mata, ka ārai hoki i te pakaru.
- Tuhipoka Rauemi:Mō te muka sima (he nui te hāora o te silica), kāore i te nui te koki i te mea nui atu i te mata o te sima.Taimana Polycrystalline (PCD)he mea nui ngā tohutohu mō te roa o te ora, ā, he iti noa ngā koki pai (+5°) hei whakahaere i te taumaha o te puehu.
