1. Rino kua tineia, kua whakamaroketia hoki
Ko te whakamātautau pakeke o te maitai kua tineihia, kua whakamaroketia hoki, e whakamahi ana i te tauine HRC a te kaiwhakamātautau pakeke Rockwell. Mena he angiangi te rauemi, ā, kāore e tika te tauine HRC, ka taea te whakamahi i te tauine HRA. Mena he angiangi te rauemi, ka taea te whakamahi i ngā tauine pakeke Rockwell mata HR15N, HR30N, HR45N rānei.
2. Rino whakapakeke mata
I roto i te whakaputanga ahumahi, i ētahi wā ka hiahiatia te pakari o te pūtake o te mea mahi, me te pakari hoki o te mata, me te ātete ki te kakahu. I tēnei wā, ka whakamahia te tinei auau-teitei, te whakakāhu matū, te whakanitiritiri, te whakakāhu waro me ētahi atu tukanga hei whakahaere i te maimoatanga whakapakeke mata ki te mea mahi. Ko te matotoru o te paparanga whakapakeke mata kei waenganui i te torutoru mirimita me te torutoru mirimita. Mō ngā rauemi he matotoru ake ngā paparanga whakapakeke mata, ka taea te whakamahi i ngā tauine HRC hei whakamātautau i tō rātou pakeke. Mō ngā maitai whakapakeke mata matotoru-waenga, ka taea te whakamahi i ngā tauine HRD, HRA rānei. Mō ngā paparanga whakapakeke mata angiangi, me whakamahi ngā tauine pakeke mata Rockwell HR15N, HR30N, me HR45N. Mō ngā paparanga angiangi o te mata whakapakeke, me whakamahi he whakamātautau pakeke micro Vickers, he whakamātautau pakeke ultrasonic rānei.
3. Rino kua whakawerahia, rino kua whakapūmautia, rino ngawari
He maha ngā rauemi maitai e hangaia ana i roto i te āhua whakamahana, i te āhua noa rānei, ā, ko ētahi pereti maitai hurihuri matao ka whakarōpūtia kia rite ki ngā nekehanga whakamahana rerekē. Ko te whakamātautau pakeke o ngā momo maitai whakamahana he tikanga whakamahi i ngā tauine HRB, ā, i ētahi wā ka whakamahia hoki ngā tauine HRF mō ngā pereti ngawari ake, angiangi ake. Mō ngā pereti angiangi, me whakamahi ngā tauine whakamātautau pakeke Rockwell HR15T, HR30T, me HR45T.
4. Kowiri tira
Ko ngā rauemi kowiri tira ka tukuna i ngā whenua pēnei i te whakamahana, te tinei, te whakamahana, me te otinga totoka. Ko ngā paerewa ā-motu e tohu ana i ngā uara pakeke o runga me o raro, ā, ko te whakamātautau pakeke ka whakamahi i ngā tauine whakamātautau pakeke Rockwell HRC, HRB rānei. Me whakamahi te tauine HRB mō te kowiri tira austenitic me te ferritic, ko te tauine HRC o te whakamātautau pakeke Rockwell me whakamahi mō te kowiri tira martensite me te whakapakeketanga, ā, ko te tauine HRN, ko te tauine HRT rānei o te whakamātautau pakeke Rockwell me whakamahi mō ngā ngongo me ngā rauemi rau angiangi kowiri tira he matotoru iti iho i te 1~2mm.
5. Rino whakarewa
Ko te whakamātautau pakeke Brinell te mea e whakamahia ana mō te maitai whakarewa, nā te mea kāore i te ōrite te hanganga moroiti o te maitai whakarewa, ā, he nui te kōhao o te whakamātautau pakeke Brinell. Nō reira, ka taea e te whakamātautau pakeke Brinell te whakaata i ngā hua whānui o te hanganga moroiti me ngā āhuatanga o ngā wāhanga katoa o te rauemi.
6. Rino maka
He maha ngā wā ka kitea te hanganga koretake o ngā rauemi rino maka me ngā kōpaka matotoru, nō reira ka whakamahia whānuitia te whakamātautau pakeke Brinell. Ka taea te whakamahi i te whakamātautau pakeke Rockwell mō te whakamātautau pakeke o ētahi wāhanga mahi rino maka. Ki te kore e ranea te wāhi i runga i te wāhanga iti o te kōpaka angiangi mō te whakamātautau pakeke Brinell, ka taea te whakamahi i te tauine HRB, HRC rānei hei whakamātautau i te pakeke, engari he pai ake te whakamahi i te tauine HRE, HRK rānei, nā te mea ka whakamahia e ngā tauine HRE me HRK he pōro maitai he 3.175mm te whānui, ka taea te whiwhi i ngā pānui toharite pai ake i ngā pōro maitai he 1.588mm te whānui.
Ko ngā rauemi rino maka mārō ka taea te whakapūmau ka whakamahia he taputapu whakamātautau pakeke Rockwell HRC. Mēnā he kore taurite te rauemi, ka taea te ine i ngā raraunga maha, ā, ka tangohia te uara toharite.
7. Karāhe kua whakatōngia (konumohe mārō)
Ko te tauine HRA a te kaiwhakamātautau pakeke a Rockwell anake te tikanga e whakamahia ana mō te whakamātautau pakeke o ngā rauemi koranu mārō.
