Mata parau mīhini ahuwhenua whakapakari maitai 30MnB5
He wāhanga matua tēnei hua mō te parau whenua i roto i ngā mīhini ahuwhenua hou. Ina whakanohoia tika ki runga i te parau, ka mahi i ngā mahi matua o te tapahi i te oneone, te kakau witi, me te ārahi i ngā poraka i te mata piko o te parau. He mea hanga mā te whakamahi i ngā hangarau matatau me te pūtaiao rauemi, ko tōna whāinga he whakarato i te ātete pai ki te kakahu, te ātete pānga, me te urunga pumau ki te oneone, ka whakaiti nui i te ātete ki te parau whenua me te whakapai ake i te penapena wahie. He kōwhiringa whakaaro nui tēnei hei whakapai ake i te pai o te mahi a te mīhini me te roa o te mahi.
1, Rauemi: He mea hanga tika mai i te maitai waro-teitei/konumohe kounga teitei (he rauemi motuhake rānei, pērā i te 65Mn), ā, i tukuna ki ngā tukanga maimoatanga wera motuhake (pēnei i te tinei me te whakamahana), ka tutuki ai te pakeketanga o te mata o te HRC 50, neke atu rānei, me te pupuri tonu i te pakari o te matua.
2, Tukanga: Ka taea te tinei i te mata tapahi i te auau-teitei, te whakakikorua rānei ki tētahi paparanga whakarewa ātete-kakahu (pērā i te tungsten carbide) hei hanga i tētahi paparanga tiaki mārō, hei ātete i te kakahu mai i te onepu, te kirikiri, me te oneone mārō, ka roa ake te ora ratonga mā te 50%-100% ki te whakataurite ki ngā hua noa.
1, Te whakaiti i te whakapaunga wahie: Mā te whakaiti i te ātete ki te parau ka whakaiti tika i te whakapaunga wahie o te tarakihana.
2, Te whakaiti i te wā kore mahi: Mā te roa o ngā wā whakakapinga ka pai ake te whai huatanga o te mahi me te whakatipu whenua i te wā tika.
3, Mīhini tiaki: Ka whakaitihia e te kaha parau maeneene te kawenga ki te pūnaha taraiwa me te whakatārewatanga.
