Me whakamātautau pakeke ngā wāhanga katoa kua whakamahanatia kia rite ki ngā whakaritenga hangarau kei runga i ngā tuhi me ngā whakaritenga o ngā tuhinga tukanga. Me whakataurite te whakamātautau pakeke ki ngā poraka tohutoro pakeke paerewa i mua i te whakamātautau, ā, ka taea anake te whakahaere i ngā whakamātautau pakeke i muri i te otinga o te whakataurite.
I mua i te tirotiro i te pakeketanga, me horoi pai te mata whakamātautau o ngā wāhanga kia tangohia katoatia te unahi, ngā paparanga kua tangohia te waro, ngā pūwero me ētahi atu poke. Kaua e toe he tohu kitea o te taputapu mīhini ki runga i te mata whakamātautau. Me whakamātautau ngā wāhanga i te pāmahana rūma hei paerewa. Mena he paku teitei ake te pāmahana o te rauemi mahi i te pāmahana taiao, kaua e haere tonu te whakamātautau kia taea rā anō te pupuri i te rauemi mahi ki te ringaringa.
Me whakarite ngā pūwāhi whakamātautau pakeke kia rite ki te mea kua tohua i roto i ngā tuhinga tukanga. Mēnā kāore he whakaritenga mārama, me whakatau ngātahi ngā pūwāhi whakamātautau e ngā miihini tukanga me ngā kaitirotiro.
Me pēhea te whiriwhiri i tētahi taputapu whakamātautau mārō e tika ana mō ngā wāhanga kua whakamahanatia
1. E whakamahia ana ngā whakamātautau pakeke Brinell mō ngā wāhanga kua whakaōritehia, kua whakamahanahia, kua tineihia, kua whakamahanahia hoki. He iti te pakeke whānui o ngā wāhanga mahi o tēnei momo, he pai te ngāwari, ā, he ōrite te hanganga o roto. Mā te poka karawiti sima nui-diameter o ngā whakamātautau Brinell ka hangaia he wāhi poka whānui e kapi ana i ngā hanganga whakarewa maha. He pumau ake te pānui pakeke toharite i whiwhihia, ā, ka taea te whakaata pono i ngā āhuatanga miihini whānui o te rauemi.
2. Ka taea te whakamahi i ngā taputapu whakamātautau pakeke Brinell momo hama mō ngā wahi mahi nunui kāore e taea te whakairi ki runga i ngā taputapu whakamātautau papa, e āhei ai te tirotiro tere i te wāhi me te kore e tapahi i ngā tauira.
3.Ka whakamahia ngā whakamātautau pakeke o Rockwell mō ngā wāhanga kua tineia. He tino pakari, he tino pakarukaru hoki ēnei wāhanga mahi kua tineia. Ka taea e te kōhao kōhao taimana Rockwell te tu atu ki te kaha whakamātautau teitei, ā, ka taea te ine ngāwari i ngā awhe pakeke teitei. Kāore tōna kōhao iti e kino ki ngā mata kua oti pai. He tere te whakamātautau me te pānui tika, he pai mō te tirotiro papatipu o ngā hua kua oti tae atu ki ngā pou, ngā pokepoke me ngā taputapu. He tēpu mahi momo-V tōna, ā, ka taea e ia te pupuri pūmau i ngā wāhanga mahi porowhita.
4.Me whakamahi ngā whakamātautau pakeke Vickers mō ngā wāhanga me ngā wahi mahi kua whakakāpūtia ki te waro me ngā paparanga angiangi kua whakapakeketia. Ko ngā wahi mahi kua whakakāpūtia ki te waro me te nitride he paparanga mata angiangi kua whakapakeketia me te papa ngohengohe kei raro. Ka tautokohia e ngā whakamātautau Vickers ngā kaha whakamātautau iti, ā, ka puta he kōhao papaku rawa e mahi ana i runga i te mata whakapakeke anake, engari kāore e uru ki roto i te papa. Mā tēnei ka taea te ine tika i te pakeketanga o te mata tūturu.
He aratohu whānui noa iho ēnei i runga ake nei mō te whiriwhiri i te whakamātautau pakeke. He uaua ngā āhuatanga whakamātautau tuturu, ā, ka pāngia te whiriwhiri taputapu e ngā rahi o ngā mea mahi, te matotoru o te paparanga whakapakeke, me te āhua o te mīhini. Me whakatau te kōwhiringa whakamutunga i runga i te āhua tuturu o ngā mea mahi. Mena ka pāngia koe e ētahi uauatanga i te whiriwhiri tauira, tēnā whakapā mai.Laizhou LaihuaKa whakaratohia e mātou he otinga taputapu whakamātautau pakeke ngaio takitahi-ki-te-kotahi.
