E rua ngā wāhanga o te maimoatanga wera o te mata: ko te maimoatanga wera tinei mata me te whakamahana i te whakamahana, ko te maimoatanga wera matū tētahi. Ko te tikanga whakamātautau pakeke e whai ake nei:
1. te whakamahana i te mata me te whakamahana i te maimoatanga wera
Ko te whakamahana i te mata me te whakamahana i te whakamahana ka mahia mā te whakamahana arataki, te whakamahana mura rānei. Ko ngā tawhā hangarau matua ko te pakeke o te mata, te pakeke ā-rohe me te hohonu o te paparanga whakapakeke whai hua. Ka taea te whakamahi i te whakamātautau pakeke Vickers, te whakamātautau pakeke Rockwell rānei mō te whakamātautau pakeke. Te kaha whakamātautau E pā ana te kōwhiringa ki te hohonu o te paparanga whakapakeke whai hua me te pakeke o te mata o te mea mahi. E toru ngā mīhini pakeke e whakamahia ana i konei.
(1) He mea nui te whakamātautau pakeke Vickers hei whakamātautau i te pakeke o te mata o ngā mea mahi i whakamahanatia. Ka taea e ia te whakamahi i te kaha whakamātautau o te 0.5-100KG hei whakamātautau i te paparanga whakapakeke mata he angiangi ki te 0.05mm te matotoru. He teitei tōna tika, ā, ka taea e ia te wehewehe i ngā mea mahi i whakamahanatia. Ko te rerekētanga iti o te pakeke o te mata, hei tāpiri, ko te hohonu o te paparanga whakapakeke whai hua ka kitea hoki e te whakamātautau pakeke Vickers, nō reira me whakarite he whakamātautau pakeke Vickers mō ngā waeine e whakahaere ana i te tukatuka maimoatanga wera mata, e whakamahi ana rānei i te maha o ngā mea mahi maimoatanga wera mata.
(2) He tino pai hoki te whakamātautau pakeke o te mata Rockwell mō te whakamātautau i te pakeke o te mea mahi kua tineihia. E toru ngā tauine mō te whakamātautau pakeke o te mata Rockwell hei whiriwhiri māu. Ka taea e ia te whakamātautau i ngā momo mea mahi kua whakapakeketia o te mata e neke atu ana i te 0.1mm te hohonutanga o te paparanga whakapakeketia whai hua. Ahakoa kāore te tika o te whakamātautau pakeke o te mata Rockwell i te teitei rite ki te whakamātautau pakeke Vickers, ka taea e ia te whakatutuki i ngā whakaritenga hei tikanga kimi mō te whakahaere kounga me te tirotiro tohu o ngā tipu maimoatanga wera. Haunga tēnā, he ngāwari hoki te whakahaere, he watea te whakamahi, he iti te utu, he tere te ine, me te pānui tika i ngā uara pakeke. Ka taea te whakamahi i te whakamātautau pakeke o te mata Rockwell hei kimi tere me te kore e whakangaro i ngā puranga o ngā mea mahi kua whakamahanatia te mata takitahi. He mea nui ki ngā wheketere tukatuka whakarewa me te hanga mīhini. Ina matotoru te paparanga whakamahanatia te mata, ka taea hoki te whakamahi i te whakamātautau pakeke o Rockwell. Ina 0.4-0.8mm te matotoru o te paparanga whakamahanatia te mata, ka taea te whakamahi i te tauine HRA. Ina nui ake te hōhonutanga o te paparanga whakapakeke i te 0.8mm, ka taea te whakamahi i te tauine HRC. Ka taea te huri ngāwari i ngā uara paerewa pakeke e toru o Vickers, Rockwell me Rockwell papatahi ki a rātou anō, ka hurihia hei paerewa, hei tuhi, hei uara pakeke rānei e hiahiatia ana e ngā kaiwhakamahi, ā, ko te ripanga tahuritanga e rite ana kei roto i te paerewa o te ao ISO. Kua hoatu te paerewa o Amerika ASTM me te paerewa Hainamana GB/T.
(3) Ina neke atu i te 0.2mm te matotoru o te paparanga whakapakeke kua whakamahanatia, ka taea te whakamahi i te taputapu whakamātautau pakeke Leeb, engari me whiriwhiri he pūoko momo-C. I te wā e ine ana, me aro ki te āhua o te mata me te matotoru whānui o te mea mahi. Kāore i te tika te taputapu whakamātautau pakeke Vickers me Rockwell i tēnei tikanga ine, engari he pai mō te ine i te wāhi mahi i roto i te wheketere.
2. te maimoatanga wera matū
Ko te maimoatanga wera matū he whakauru i ngā ngota o tētahi, ētahi rānei o ngā huānga matū ki roto i te mata o te mea mahi, ā, ka huri te hanganga matū, te hanganga me te mahi o te mata o te mea mahi. Whai muri i te tinei me te whakamahana i te pāmahana iti, he pakeke te mata o te mea mahi, ā, he ātete ki te kakahu, he kaha hoki ki te ngenge pa, ā, he kaha, he pakari hoki te uho o te mea mahi. Ko ngā tawhā hangarau matua o te mea mahi maimoatanga wera matū ko te hohonutanga o te paparanga whakapakeke me te pakeketanga o te mata. Ko te tawhiti e heke ai te pakeketanga ki te 50HRC ko te hohonutanga o te paparanga whakapakeke whai hua. He rite te whakamātautau pakeketanga o te mata o ngā mea mahi tukatuka wera matū ki te whakamātautau pakeketanga o ngā mea mahi mata kua tineihia te weratanga. Ka taea te whakamahi i ngā whakamātautau pakeketanga Vickers, ngā whakamātautau pakeketanga mata Rockwell, ngā whakamātautau pakeketanga Rockwell rānei. Hei kite i te whakamātautau pakeketanga, ko te matotoru o te nitriding anake he angiangi ake, ko te tikanga kāore e neke atu i te 0.7mm, kātahi ka kore e taea te whakamahi i te whakamātautau pakeketanga Rockwell.
3. te maimoatanga wera ā-rohe
Mena he nui te pakeke o ngā wāhanga maimoatanga wera ā-rohe, ka taea te whakahaere i te maimoatanga wera tinei ā-rohe mā te whakamahana hiko, me ētahi atu. Me tohu te tūranga o te maimoatanga wera tinei ā-rohe me te uara pakeke ā-rohe o aua wāhanga ki te tuhi, ā, me whakahaere te whakamātautau pakeke o ngā wāhanga ki te wāhi kua tohua, ka taea e te taputapu whakamātautau pakeke te whakamahi i te whakamātautau pakeke Rockwell hei whakamātautau i te uara pakeke HRC. Mena he papaku te paparanga whakapakeke maimoatanga wera, ka taea te whakamahi i te whakamātautau pakeke Rockwell mata hei whakamātautau i te uara pakeke HRN.
