Ina tohua e ngā miihini me ngā kaihoko he wiri pokapū DIN 333, ko tētahi o ngā pātai e tino pā mai ana ko: "He aha te rerekētanga i waenga i te Momo A me te Momo B — ā, ko tēhea te mea e hiahiatia ana e au?"
He pātai tika tēnei. He rite tonu te koki anga 60° o ngā momo e rua, he rite tonu te paerewa DIN 333, ā, he rite tonu ngā rauemi e wātea ana. Engari he rerekētanga āhuahanga nui kei waenganui i a rāua — he rerekētanga e pā tika ana ki te pai o te mau o tō kōhao waenga i te tukanga mīhini.
E whakamārama mārama ana tēnei aratohu i te rerekētanga, me ngā ripanga ine DIN 333 mō ngā momo e rua.
He aha te Wiri Pokapū DIN 333?
Ka whakamahia he wiri pokapū — e kiia ana hoki he wiri whakakotahi me te totohu tatau — hei hanga i tētahi kōhao kōniko 60° tika i te pito o tētahi mea mahi i mua i te hurihanga i waenga i ngā pokapū i runga i te mīhini hurihuri. Mā te kōhao pokapū ka noho pūmau te pokapū hiku, e whakarite ana i te ōritetanga me te tika o te tūnga puta noa i ngā mahi huri, huri, mira rānei e whai ake nei.
Ko te DIN 333 te paerewa Tiamana (Deutsches Institut für Normung) e whakahaere ana i te āhuahanga, ngā ine, me ngā manawanui o ngā wiri pokapū 60°. E toru ngā momo e tautuhia ana: Momo A, Momo B, me te Momo R. E arotahi ana tēnei tuhinga ki ngā momo e rua e tino tohua ana: A me B.
Te Rerekētanga Matua: Kotahi te Chamfer me te Rua
Tohutoro Tere: Momo A me te Momo B
| Momo A (DIN 333-A) | Momo B (DIN 333-B) | |
| Āhuahanga chamfer | Kōhao kotahi 60° | 60° te anga whakarara + 120° te parenga |
| Te tiaki i te waha o te kōhao | Kāore | Āe — 120° te kaitiaki o te tomokanga |
| Te whānui o te tinana (d2) | Iti ake | Nui ake (mō te d1 ōrite) |
| Te roa katoa (L1) | Poto ake | Roa ake |
| Pai rawa atu mō | Te hurihanga whānui, te whakamahinga tonu | Maha-mahinga, rokiroki i waenga i ngā wāhanga |
| Te whakaritenga tika | Paerewa | Teitei ake — te mata nohoanga e tiakina ana |
| Ngā kōwhiringa rauemi | M2, M35 | M2, M35 |
| Whakaotinga mata | Kanapa / TiN | Kanapa / TiN |

Ngā Kōwhiringa Rauemi: M2 vs. M35
E rua ngā momo HSS e wātea ana mō ngā wiri pokapū Momo A me Momo B. Kāore he rerekētanga o te momo rauemi ki te whiriwhiri — kei te rauemi o te taputapu mahi me te rahinga o te mahi.
M2 HSS — Paerewa Paerewa
Ko te M2 (HS6-5-2) te momo HSS e whakamahia whānuitia ana puta noa i te ao. He pakari pai, he ātete pono ki te kakahu, ā, he rite tonu te mahi puta noa i te whānuitanga o ngā rauemi mahi - te maitai ngawari, te konumohe, te rino maka, te parahi, me te nuinga o ngā konganuku kore-ferrous. Ko ngā wiri pokapū M2 te whiringa paerewa mō ngā taiao miihini whānui.
M35 HSS-Co — Te Karāhe Kobalt mō ngā Whakamahinga Tino Uaua
Ka tāpirihia e te M35 (HS6-5-2-5, e mōhiotia ana ko te HSSCo5) he 5% konupora ki te turanga M2. Ka whakapiki ake tēnei i te ātete wera ki te 630–650°C pea, ā, ka whakapiki ake i te pakeke ki te 63–66 HRC. Ko te M35 te momo pai rawa atu ina whakamahia te maitai kore waikura, te maitai koranu, ētahi atu rauemi uaua ki te mīhini, i roto rānei i te hanga nui-rahi e whai tikanga ana te roa o te ora o ngā taputapu.
Ngā Kōwhiringa Whakamutunga Mata
Me pēhea te whiriwhiri: He aratohu whakatau whai hua
Mena kei te pokapū koe i tētahi mea mahi ka hurihia tonutia i roto i te whakatakotoranga kotahi, ko te Momo A te kōwhiringa tika. He māmā ake, he poto ake, ā, e kapi ana i te nuinga o ngā mahi pokapū mīhini tārai paerewa.
Mena kei roto i tō tukanga tētahi o ēnei e whai ake nei, tohua te Momo B:
• Ka neke te mea mahi i waenga i ngā mīhini, ka neke rānei i waenga i ngā mahi
• Ka rongoatia, ka whakahaerea rānei ngā wāhanga i muri i te whakatōnga i waenganui, ā, i mua i te hurihanga whakamutunga
• Me whai āhua pūmau, ka taea te whakahoki i te pūrua waenga o ō manawanui puta noa i te wā whakaputa
• Kei te mahi koe me ngā toki tino tika ina kore e whakaaetia te rere mai i te kōhao pokapū kua pakaru
Mēnā kei te ruarua koe, ko te Momo B te whakaritenga haumaru ake. Kāore te anga tiaki tāpiri e tāpiri i te uaua ki te mahi keri — ka whakarite noa kia noho tonu te mata o te nohoanga.
