Hei taputapu whakamātautau pakeke motuhake mō ngā wahi mahi nunui i roto i te mara whakamātautau ahumahi, ko teMomo kētiHe mea nui te mahi a te taputapu whakamātautau pakeke a Rockwell i roto i te whakahaere kounga o ngā hua whakarewa nui pērā i ngā rango maitai. Ko tōna painga matua ko tōna kaha ki te whakatutuki tika i ngā hiahia ine o ngā wahi mahi nui, inā koa mō ngā wahi mahi motuhake pērā i ngā rango maitai, he mata piko, he nui ngā rahinga me ngā taumaha taumaha. Ka pakaruhia e ia ngā herenga o ngā taputapu whakamātautau pakeke tuku iho mō te rahi me te taumaha o ngā wahi mahi.
Mō te hoahoa hanganga,Momo kētiKo ngā kaiwhakamātautau pakeke o Rockwell e whakamahi ana i te tikanga pumauMomo kētihe hanganga anga, he nui te kaha ki te kawe me te pakari, ā, ka taea te whakauru ngāwari i ngā wahi mahi rango rino he nui ngā diameter me ngā roa. Kāore e hiahiatia he whakahaere uaua, he whakarerekētanga pumau rānei mō te wahi mahi i te wā whakamātautau, ā, ka taea te whakanoho tika ki runga i te papa whakamātautau. Ka urutau te tikanga ine whakarerekētanga o te taputapu ki te radian mata piko o te rango rino, kia mau ai te piri poutū o te indenter ki te mata o te wahi mahi, me te karo i ngā hapa whakamātautau i puta mai i te āhua koretake o te wahi mahi.
Ko te mahi "whakamātautau ipurangi" te kaupapa matua. I roto i te raina whakaputa o ngā mea mahi pēnei i ngā rango maitai, ko teMomo kētiKa taea te whakauru i te whakamātautau pakeke o Rockwell ki roto i te tukanga whakaputa aunoa. Mā te hononga hononga ki te raina whakaputa, ka tutuki te whakamātautau pakeke o ngā wahi mahi i te wā tukatuka. Hei tauira, i muri i ngā tukanga matua pēnei i te hurihuri i te rango maitai me te maimoatanga wera, ka taea e te taputapu te whakaoti tere i te whakamātautau pakeke me te kore e whakawhiti i te wahi mahi ki te wāhi whakamātautau kore-aho. Ehara i te mea ka whakaiti noa i te ngaronga me te utu wā i roto i te tukanga whakahaere wahi mahi, engari ka taea hoki te urupare wawe mena ka tutuki te pakeke o te hua i ngā paerewa, ka āwhina i te raina whakaputa ki te whakarerekē i ngā tawhā tukanga i te wā tūturu me te whakarite i te pumau o te kounga hua i roto i te pūtake.
Hei tāpiritanga, ko teMomo kētiKei te taputapu whakamātautau pakeke o Rockwell he pūoko tino tika me te pūnaha tukatuka raraunga atamai, ka taea te whakaatu i te uara pakeke i muri tonu i te whakamātautau, me te tautoko i te rokiroki raraunga, te whai me te tātari, e tutuki ai ngā hiahia o te tuhi me te whakahaere raraunga kounga i roto i te whakaputanga ahumahi. Ahakoa e whakamahia ana mō te tirotiro wheketere o ngā ipu pēhanga teitei pēnei i ngā rango hau maori me ngā rango oko pēhanga, te tirotiro tauira mahi rānei o ngā wāhanga maitai hanganga nui, ka taea e ia te whakarato i te taurangi pono mō te whakahaere kounga pakeke o ngā wahi mahi nui me ōna āhuatanga whai hua, tika me te watea. Ko tēneiMomo kētiKa whakamahia e te taputapu whakamātautau pakeke o Rockwell ngā tauine Rockwell (ngā kawenga o te 60, 100 me te 150kgf) me te superifiNgā pauna Rockwell (me ngā kawenga o te 15, 30 me te 45kgf) hei whakamātautau. I taua wā anō, ka taea te whakauru atu ki te Brinell load HBW. Ka whakamahia e ia he hanganga whakahaere kawenga pūtau, ā, he pūoko kaha tino tika hei whakarite i ngā hua whakamātautau tika me te pumau. Ka whakahaerehia mā te mata pā o te rorohiko ahumahi kua hangaia, ā, he mahi tukatuka raraunga me te kaweake raraunga.
TeneiMomo kētiKa taea e te mīhini whakamātautau pakeke o Rockwell te whakaoti aunoa i te tukanga whakamātautau mā te whakamahi i te kī kotahi. Ka whakatinanahia e tēnei mīhini he tukanga whakamātautau "tino aunoa". Me whakatakoto noa e te kaiwhakahaere te mea mahi ki runga i te atamira, tīpakohia te tauine whakamātautau e hiahiatia ana, ka pāwhiri i te pātene tīmata. Mai i te uta ki te tiki i te uara pakeke, kāore he wawaotanga tangata i roto i te tukanga. Kia oti te whakamātautau, ka hoki aunoa te pane ine ki te tūranga tīmatanga, he mea watea mō te kaiwhakahaere ki te whakakapi i te mea mahi.
I tēnei rā, i tae mai he waea mai i tētahi kiritaki e hiahia ana ki te whakamātautau i te pakeke o te rino maka. Heoi, kāore i te tino teitei te auau o te whakamahinga, ā, kāore hoki i te tino teitei te whakaritenga mō te pakeke. Ka taea hoki te whakamahi i tēnei taputapu whakamātautau pakeke Rockwell hei whakamātautau i te HRB, kātahi ka huri ki te uara pakeke Brinell HBW.
