Tātari Kōwhiringa Momo o ngā Taputapu Whakamātautau Mārō mō ngā Wāhanga Mahi Nui me te Taumaha

E mōhiotia whānuitia ana, he herenga anō tō ia tikanga whakamātautau pakeke—ahakoa mā te whakamahi i a Brinell, Rockwell, Vickers, i ngā taputapu whakamātautau pakeke kawe rānei a Leeb—ā, kāore he mea e tika ana mō te ao whānui. Mō ngā taputapu mahi nunui, taumaha hoki, he āhua āhua koretake pērā i ngā mea e whakaaturia ana i roto i ngā tauira hoahoa i raro nei, e whakamahia whānuitia ana ngā taputapu whakamātautau pakeke kawe a Leeb i roto i ngā tikanga whakamātautau maha hei whakahaere i tō rātou pakeke.

He tikanga whakamātautau hihiri tā te taputapu whakamātautau pakeke a Leeb, ā, he maha ngā āhuatanga e pā ana ki te tika o tana whakamātautau pakeke, pērā i te modulus elastic o te rauemi, te kakahu o te pōro indenter, te taratara o te mata o te mea mahi, te radius o te piko, me te hohonu o te paparanga whakapakeke mata. Ki te whakatauritea ki ngā tikanga whakamātautau pūmau o ngā taputapu whakamātautau pakeke a Brinell, Rockwell, me Vickers, he nui ake te hapa o tana whakamātautau. Nō reira, ki te hiahiatia he tika teitei mō te whakamātautau pakeke, me pēhea te whiriwhiri i tētahi taputapu whakamātautau pakeke?

I te wā e whakamātautau ana i ngā mea mahi nunui, taumaha hoki mā te whakamahi i ngā taputapu whakamātautau pakeke noa, ko te utaina o ngā mea mahi i mua i te whakamātautau, ko te utaina me te tango i te taputapu whakamātautau pakeke i te wā whakamātautau, me te tango i ngā mea mahi i muri i te whakamātautau ka nui rawa te mahi e hiahiatia ana mō te tukanga whakahaere. Nō reira, me pēhea te whiriwhiri i tētahi taputapu whakamātautau pakeke?

E taunakihia ana kia whakamahia ngā whakamātautau pakeke e rua me te hanganga pane hiki hei whakaoti i te tukanga whakamātautau katoa, pērā i tā mātou whakamātautau pakeke Rockwell ipurangi momo kēti nui kua whakaritea mō te papa HRZ-150GE me te whakamātautau pakeke Rockwell aunoa mō te piki me te heke o te pane papamahi SCR3.0.

Mā tēnei otinga whakamātautau pakeke ka taea te whakamātautau pakeke o Rockwell i runga anō i ngā paerewa whakamātautau pakeke o te ao (pērā i te ISO 6506-1:2014 me te ISO 6507-1:2018). Waihoki, mō te whakamātautau pakeke o Vickers me Brinell, ka taea hoki te whakatinana i te hanganga hiki aunoa o te pane whakamātautau. I taua wā, ka tutuki i a ia ngā whakaritenga o te whakamātautau tino tika mō ngā mahi taumaha me te whakaputanga whai hua.
