I te whakamātautau i te pakeke o ngā pae porowhita maitai waro he iti ake te pakeke, me whiriwhiri he taputapu whakamātautau pakeke kia tika ai, kia whai hua ai hoki ngā hua o te whakamātautau. Ka taea e tātou te whakaaro ki te whakamahi i te tauine HRB o te taputapu whakamātautau pakeke Rockwell.
Ko te tauine HRB o te taputapu whakamātautau pakeke Rockwell e whakamahi ana i tētahi kōhao poro maitai he 1.588mm te whānui, ā, he 100KG te kaha whakamātautau e ōrite ana. Ko te whānuitanga ine o te tauine HRB kua whakatakotoria ki te 20-100HRB, he mea e tika ana mō te whakamātautau pakeke o te nuinga o ngā rauemi porowhita maitai waro he iti ake te pakeke.
1. Mena kua tineia te pae porowhita maitai waro, ā, he tino pakeke te HRC40 – HRC65, me whiriwhiri e koe he taputapu whakamātautau pakeke Rockwell. He ngāwari, he tere hoki te whakamahi i te taputapu whakamātautau pakeke Rockwell, ā, ka taea te pānui tika i te uara pakeke, he mea pai mō te ine i ngā rauemi tino pakeke.
2. Mō ētahi pae porowhita maitai waro kua tukatukahia ki te whakakāpuru, te whakanitiriti, me ētahi atu, he teitei te pakeke o te mata, ā, he iti te pakeke o te matua. Mēnā e tika ana kia ine tika i te pakeke o te mata, ka taea te whiriwhiri i tētahi taputapu whakamātautau pakeke Vickers, i tētahi taputapu whakamātautau pakeke iti rānei. He tapawhā te kōhao o te whakamātautau pakeke Vickers, ā, ka tatauhia te uara pakeke mā te ine i te roa whakarara. He teitei te tika o te ine, ā, ka taea te whakaata tika i ngā huringa pakeke ki te mata o te rauemi.
3. Haunga te tauine HRB o te whakamātautau pakeke Rockwell, ka taea hoki te whakamahi i te whakamātautau pakeke Brinell hei whakamātautau i ngā rauemi pae porowhita maitai waro iti-pakari. I te whakamātautau i ngā pae porowhita maitai waro, ka waiho e tōna kōhao he wāhi kōhao nui ki te mata o te rauemi, ka taea te whakaata whānui me te whānui i te pakeke toharite o te rauemi. I te wā e whakahaerehia ana te whakamātautau pakeke, kāore te whakamātautau pakeke Brinell i te tere me te ngāwari pērā i te whakamātautau pakeke Rockwell. Ko te whakamātautau pakeke Brinell te tauine HBW, ā, he rerekē ngā kōhao e ōrite ana ki te kaha whakamātautau. Mō ngā pae porowhita maitai waro he iti te pakeke, pērā i te hunga kei roto i te āhua whakamahana, ko te pakeke kei te nuinga o te wā kei waenganui i te HB100 – HB200, ā, ka taea te whiriwhiri i te whakamātautau pakeke Brinell.
4. Mō ngā pae porowhita maitai waro he whānui nui, he āhua ōrite hoki, he maha ngā momo whakamātautau pakeke e whakamahia whānuitia ana. Heoi, ki te iti te whānui o te pae porowhita, pērā i te iti iho i te 10mm, ka pā pea te whakamātautau pakeke Brinell ki te tika o te ine nā te nui o te kōhao. I tēnei wā, ka taea te whiriwhiri i te whakamātautau pakeke Rockwell, i te whakamātautau pakeke Vickers rānei. He iti ake te rahi o te kōhao, ā, ka taea te ine tika ake i te pakeke o ngā tauira iti.
5. Mō ngā pae porowhita maitai waro āhua koretake, he uaua ki te whakatakoto ki runga i te papa mahi o tētahi taputapu whakamātautau pakeke noa mō te ine, ka taea te whiriwhiri i tētahi taputapu whakamātautau pakeke kawe, pērā i te taputapu whakamātautau pakeke Leeb. Ka whakamahia he taputapu pānga hei tuku i tētahi tinana pānga ki te mata o te mea e inehia ana, ā, ka tatau i te uara pakeke i runga i te tere o te pekepeke o te tinana pānga. He ngāwari ki te whakahaere, ā, ka taea te mahi ine i runga i te papa mahi o ngā āhua me ngā rahi rerekē.
