Ko te whakamātautau pakeke te mea e whakamahia ana mō te whakamātautau pakeke o te maitai hanga me te rino maka kāore i te ōrite te hanganga. He pai te ōrite o te pakeke o te maitai hanga me te rino maka hina ki te whakamātautau kume. Ka taea hoki te whakamahi mō ngā konganuku kore-ferro me te maitai ngawari, ā, ka taea e te poka pōro iti te ine i ngā rauemi iti me ngā rauemi angiangi.
Ko te pakeketanga e pā ana ki te kaha o tētahi rauemi ki te ātete i te whakarerekētanga ā-rohe, inā koa te whakarerekētanga kirihou, te kōpiko, te rakuraku rānei, ā, ko tētahi o ngā tohu mahi nui o ngā rauemi whakarewa. I te nuinga o te wā, ko te teitei ake o te pakeketanga, ko te pai ake o te ātete kakahu. He tohu hei ine i te ngawari me te pakeketanga o ngā rauemi. E ai ki ngā tikanga whakamātautau rerekē, e toru ngā momo o te pakeketanga. Me titiro tātou ki ia momo:
Te pakeke o te rakuraku:
Ko te tikanga matua he whakataurite i te ngawari me te pakeke o ngā kohuke rerekē. Ko te tikanga he whiriwhiri i tētahi tokotoko he mārō tetahi pito, he ngawari tetahi pito, ka tukuna te rauemi hei whakamātautau mā te tokotoko, ka whakatau i te pakeke o te rauemi hei whakamātautau kia rite ki te tūranga o te rakuraku. I runga i te kounga, ka roa ngā rakuraku o ngā mea mārō, ka poto ngā rakuraku o ngā mea ngohengohe.
Te pakeketanga pēhi-ki-roto:
Ko te tikanga matua mō ngā rauemi whakarewa, ko te whakamahi i tētahi kawenga hei pēhi i te kōhao kua tohua ki roto i te rauemi hei whakamātautau, ā, ka whakataurite i te ngawari me te pakeke o te rauemi hei whakamātautau mā te rahi o te whakarerekētanga kirihou ā-rohe i runga i te mata o te rauemi. Nā te rerekētanga o te kōhao, te kawenga me te roa o te kawenga, he maha ngā momo pakeke kōhao, ko te nuinga ko te pakeke Brinell, te pakeke Rockwell, te pakeke Vickers me te pakeke moroiti.
Te pakeketanga o te hokinga whakamuri:
Ko te tikanga matua mō ngā rauemi whakarewa ko te tuku i tētahi hama iti motuhake kia taka noa mai i tētahi teitei hei pā ki te tauira o te rauemi e whakamatautauria ana, ā, ka whakamahia te nui o te pūngao taumahatanga kua rongoatia (kātahi ka tukuna) i roto i te tauira i te wā o te pānga (mā te whakahokinga mai o te hama iti) (te ine i te teitei peke) hei whakatau i te pakeke o te rauemi.
Ko te taputapu whakamātautau pakeke i hangaia e Shandong Shancai/Laizhou Laihua Testing Instrument he momo taputapu whakamātautau pakeke whakapiko, e tohu ana i te kaha o te rauemi ki te ātete i te urunga mai o ngā mea pakeke ki roto i tōna mata. E hia ngā momo kei reira?
1. Whakamātautau Pakeke Brinell: E whakamahia ana hei ine i te pakeke o te rino maka, te maitai, ngā konganuku kore-ferrous me ngā koranu ngohengohe. He tikanga whakamātautau pakeke tino tika.
2. Whakamātautau pakeke Rockwell: he whakamātautau pakeke Rockwell ka taea te whakamātautau i te pakeke o te konganuku mā te pā atu ki te tauira i te taha kotahi. Ka whakawhirinaki ki te kaha aukume hei mimiti i te pane whakamātautau pakeke Rockwell ki te mata maitai, ā, kāore e hiahiatia kia tautoko i te tauira.
3. Whakamātautau Pakeke Vickers: He hua hangarau teitei te Whakamātautau Pakeke Vickers e whakauru ana i ngā hikohiko me ngā hikohiko. He hou te āhua o te mīhini, he pai te pono, te whakahaere me te ngāwari ki te mārama. He taputapu whakamātautau pakeke a S me Knoop.
4. Whakamātautau pakeke o Brockwell: He pai te whakamātautau pakeke o Brockwell mō te whakatau i te pakeke o ngā konganuku rino, ngā konganuku kore-rino, ngā koranu mārō, ngā paparanga warowaihā me ngā paparanga matū-rongoa.
5. Whakamātautau mārō: He taputapu tika te whakamātautau mārō mō te whakamātautau i ngā āhuatanga o ngā rauemi whakarewa i roto i ngā mīhini, te mahi whakarewa me ētahi atu ahumahi, ā, e whakamahia whānuitia ana i roto i ngā ahumahi maha.
6. Whakamātautau Pakari a Leeb: Ko tōna kaupapa matua ko te pānga o tētahi tinana pānga me tētahi taumaha motuhake ki te mata o te tauira i raro i tētahi kaha whakamātautau, ā, ka ine i te tere pānga me te tere whakahoki o te tinana pānga i te tawhiti o te 1 mm mai i te mata tauira, mā te whakamahi i ngā kaupapa hikohiko, ka puta he ngaohiko e ōrite ana ki te tere.
7. Kaiwhakamātautau pakeke Webster: Ko te kaupapa o te kaiwhakamātautau pakeke Webster he kōhao maitai mārō me tētahi āhua, ka pēhia ki roto i te mata o te tauira i raro i te kaha whakamātautau puna paerewa.
8. Whakamātautau Pakeke Barcol: He whakamātautau pakeke whakapūpū. Ka pēhia he whakapūpū motuhake ki roto i te tauira i raro i te mahi a te kaha puna paerewa, ā, ka whakatauhia te pakeke o te tauira mā te hohonutanga o te whakapūpū.
