Pūwāhi Parau Whakarewahia he Koranu, Mata Parau Koranu Ātete-Kakahu, Koro Parau Whakarewahia

Whakaahuatanga Poto:

Ko ngā pū parau i whakarewaina ki te konukōre he wāhanga mīhini ahuwhenua e tere ana te pakaru

i hangaia mō ngā mahi parau taumaha. He mea hanga te tinana matua ki

te maitai waro/konumohe kounga teitei hei rauemi turanga, me te tapahi

kua honoa te taha ki tētahi paparanga koranu ātete-mau pakari (pērā i te koranu tungsten-chromium-boron,

(carbide sima) mā te tukanga whakarewa/whakapiripiri koranu,

ā, ka tukatukahia mā te maimoatanga wera whānui me te maimoatanga ārai-waikura whakapōuri/whakamahinga hiko.

Taipitopito Hua

Ngā Tohu Hua

He pakari te hanganga o te hua, he koi te mata, ā, he tino kaha te ātete ki te kakahu,

he tino pai te ātete ki te pānga me te ātete ki te whakarerekētanga. Ka taea te mahi mō te wā roa i roto i

ngā taiao oneone uaua pēnei i te oneone kohatu, te oneone uku taumaha me te oneone onepu, me tōna roanga mahi

he roa rawa atu i ērā o ngā pū parau noa. Ko te hoahoa pūrua paerewa he

he pai mō ngā momo parau, ngā parau hurihuri, ngā parau ngaki whenua, ngā parau hurihuri me ētahi atu parau ahuwhenua

mīhini, he ngāwari te tāutanga me te kaha o te whakamahi. He taputapu matua ātete-mau

mō te parau hohonu ahuwhenua me te whakarite whenua, ā, ka taea te whakarite i te rahi me te koranu

te tauira e ai ki ngā tauira me ngā tikanga mahi rerekē.

1, Te roa o te ora ratonga
Ka taea e te pakeke o te paparanga mahi te eke ki te HRC 58-63, ā, ko tōna ātete ki te kakahu he 3-5 ngā wā i tērā o ngā pito parau maitai 65Mn noa. I roto i ngā oneone nui te silica, te onepu me ētahi atu oneone kua pakaru rawa, ka taea e te rohe mahi kotahi te eke ki te 800-1200 eka, ka whakaiti nui i te auau o te whakakapinga mara.

2, Mahi whakakoi-ake
Mā te tohatoha ahurei o te koranu whakarara ka mau tonu te koki tapahi koi o te pito parau i te wā e mau ana, ka whakaiti i te ātete ki te kukume mā te 20% -30% ki te whakaritea ki ngā pito parau kua kore e whakamahia, ā, ka penapena i te whakapaunga wahie.

3、Ātete ki te whati me te pānga
He mea hanga te anga o te anga ki te maitai pakari, iti-koranu, kua oti te whakamahana me te whakamātao. Ka taea e ia te mimiti i te taumaha pānga ohorere i puta mai i ngā kōhatu me ngā pakiaka rākau, ā, ka whakakore i te tūponotanga o te whati, te whati rānei o te mata.

4、Te whānui o te tāutanga
I hangaia kia rite tonu ki ngā paerewa o te ao me ngā tauira matua (pērā i a Leiken, Gran, me te raupapa 1L o te motu), ka whakahaerehia te mokowā o ngā kōhao pūtu me te tika o te mata tūnga i roto i te ± 0.5mm, ā, ka tautoko i te whakakapinga tika me te kore whakarerekētanga.
