Mīhini Ahuwhenua, Mīhini Whakatō Puna

Whakaahuatanga Poto:

He taputapu matua tēnei mīhini puna momo-S mō ngā mīhini ahuwhenua.

pērā i ngā kaiparau me ngā parau. He mea hanga te tinana matua mai i te kaha teitei

maitai puna pērā i te maitai 65Mn, i tukatukahia mā te maimoatanga wera

me te tinei, he tino ngāwari, he ātete ki te kakahu me te ātete ki te ngenge.

Ka taea e ia te tu atu i te pānga me te piko o ngā mahi parau whenua auau teitei, ā, kāore e ngāwari ki te whakapēke, ki te whati rānei.

Ngā Tohu Hua

Ngā Mahi Tautoko: Ka taea te whakamahi me ngā kaiparau hei whakaoti i te ruinga i mua i te rui

te whakarite whenua, te whakahaere tipu me ngā mahi whakatō oneone,

ā, ka taea hoki te whakamahi mō te parau, te kuru oneone me te whakataurite i te whenua.

He pai mō ngā tauira ahuwhenua hou pēnei i te tiaki taiao

te parau me te kore rui, te whakaiti i te horo o te oneone, me te whakapai ake i te whai huatanga o te parau.

Taupū pakeke: Ko te pakeke o te wāhi mahi kei waenganui i te HRC 42-48, e whakarite ana i te ātete ki te kakahu me te karo i te tūponotanga o te whati i puta mai i te pakarukaru nui.

Te maimoatanga mata: mā te whakamahi i te peita rehu, te peita rehu, te maimoatanga hiko rānei, he tino ātete ki te waikura me te waikura, ā, ka taea te urutau ki te haumākū tiketike me te taiao oneone ahuwhenua pH teitei.

Tauira/rahi hua: 12x45 (e pā ana ki te whānui whakawhiti-wāhanga rauemi o te 12mm, me ngā tawhā roa tāutanga, koki rānei e ai ki ngā paerewa raupapa 45).

Te hanganga rauemi: Ko te 65Mn (te maitai konupūmā 65) te 60Si2Mn rānei (te maitai puna konupūmā silicon) te rauemi matua. He momo maitai motuhake ēnei rauemi e rua mō te hanga puna, he tino teitei ngā rohenga pūmau me te ātete ki te ngenge.

Tukanga maimoatanga wera: Whai muri i te tinei me te whakamahana tika, ka whakarite kia whiwhi te hua i tētahi hanganga martensite whakamahana ōrite.

Te kaha ki te whakatauira me te karo i ngā arai: Ina tūtaki ki ngā mea pakeke (pērā i ngā toka, ngā pakiaka rākau) me ngā whenua pōkarekare i te wā e mahi ana i te mara, ka whakamahia e te puna āhua-S tōna āhua pīngore hei akiaki i te pito o te koko kia hiki ake, kia hoki whakamuri rānei, ka tere te tautuhi anō i muri i te karo i ngā arai. Mā tēnei āhuatanga "hoatu me te whakahoki" ka whakaiti i te tūponotanga o te piko, te whati rānei o ngā niho me te anga o te koko nā te pānga.

Mahi Matua: Ka tāuta ki ngā mīhini ahuwhenua pēnei i ngā mīhini mahi ahuwhenua,

ngā parau me ngā harou, e whakamahia ana mō te parau i waenga i ngā rarangi, te whakangāwari i te oneone,

te tango taru me te ngau i ngā hua. Me te kore e hurihia te paparanga oneone,

ka wetekina te oneone kiato, ka whakapai ake i te hau me te urunga wai o te oneone,

ka tapahia ngā pakiaka taru, ka tangohia ngā taru o te mara, ā, ka waihanga i te taiao pai mō te tupu o ngā hua.
