Ngā wāhanga mīhini ahuwhenua: te maikuku hama, te mata kuru taumaha
Ko ngā maikuku hama, hei wāhanga matua, hei wāhanga ngāwari hoki o ngā mīhini ahuwhenua pērā i ngā mīhini whakahoki kakau witi, ngā mīhini kuru, me ngā mīhini tango kakau witi, ka whakatau tika i te whai huatanga me te whai huatanga o ngā mahi mara. He mea hanga motuhake tēnei maikuku hama mō ngā āhuatanga mara kaha, taumaha, i hangaia mā te whakamahi i te hangarau hanga tika me ngā rauemi ātete-kakahu hiato. Ko tōna whāinga he whakaoti i ngā āhuatanga mamae o ngā maikuku hama maitai tuku iho, pērā i te ngāwari o te whati, te ātete ngoikore ki te kakahu, me te pānga kuru koretake, he mea pai mō te whakarite whenua ahuwhenua hou me te tukatuka kakau witi.
Ka whakamahia e tēnei hua te maitai konupora-teitei kounga teitei, te maitai koranu 42CrMo rānei hei rauemi turanga, i hangaia mā te hanga mate pāmahana teitei. Mā tōna hanganga matotoru o roto ka whakakorea ngā hapa whakarewa pērā i te porosity me ngā kōhao onepu, ka ārai i te tūponotanga o te pakarukaru nā te pānga nui i te wā e whakamahia ana.
Mō te mata tapahi me te pito o te maikuku hama, te wāhi e tino kino ana te pakaru, i whakamahia e mātou te hangarau whakarewa plasma hei whakakikorua i tētahi paparanga ātete-kakahu koranu konupora-teitei. Ka tutuki i tēnei paparanga whakarewa te pakeke o te HRC58-62, ka tino whakaroa i te tere pakaru o te rauemi turanga i te wā e huri tere ana ki runga i te kakau witi, te oneone, me te kirikiri.
Ka tukatukahia te kōhao o te maikuku hama ki te tinei auau teitei, ā, ka whakauruhia ki te pūwero ātete puehu kua whakapakaritia hei whakarite i te tika me te ngāwari o te hononga ki te pou titi hurihuri, kia kore ai e whakanuia te kōhao pou me te aukati i puta mai i te kakahu wawe, me te whakaroa i te roa o te ora ratonga o te pūnaha hurihuri katoa.
Te pānga haehae tino pai: Mā te maimoatanga wera ahurei me te hoahoa āhua mata ka tino kaha te pānga o ngā maikuku hama i raro i te hurihanga tere. Ki te whakatauritea ki ngā maikuku hama noa, he kaha ake tōna kaha ki te haehae i ngā kakau o ngā hua roa pērā i te kānga me te miro, ā, he ōrite ake te roa o te toenga haehae, he mea pai mō ngā mahi parau hohonu o muri mai me te pirau tere.
He roa te ora, he nui te utu: Nā te paparanga ātete-mau o te hiato bimetallic, he 1.5 ki te 2 ngā wā roa ake te ora o tēnei hua i ngā maikuku hama maka noa i roto i ngā taiao mahi taumaha kei roto he onepu me te oneone. Ka whakaitihia e tēnei te auau o te wā kore mahi mō ngā whakakapinga, ā, ka tino whakaitihia ngā utu whakahaere katoa a te kaiwhakamahi.
Te haumaru me te pono teitei: Ka whakamatautauria ia maikuku hama kia pakari te taurite hihiri, me te whakahaere i ngā hapa kounga i roto i te whānuitanga tino iti. Ko te mahi taurite hihiri tino pai ka whakaiti i ngā wiri rerekē o te tarakihana me te pouaka miihini i te wā e whakamahia ana, ka tiaki i ngā peera o te pou matua, ā, ka whakapai ake i te whakamarie taraiwa.
