Kaiwhakamātautau Pakeke a Leeb
I tēnei wā, e whakamahia whānuitia ana te taputapu whakamātautau pakeke Leeb i roto i te whakamātautau pakeke o ngā whakarewanga. E whakamahi ana te taputapu whakamātautau pakeke Leeb i te kaupapa o te whakamātautau pakeke hihiri, ā, e whakamahi ana i te hangarau rorohiko hei whakatutuki i te whakaiti me te hikohiko o te taputapu whakamātautau pakeke. He māmā noa iho, he watea hoki te whakamahi, he māmā ake te pānui, ā, ka taea te huri ngāwari i ngā hua whakamātautau ki ngā uara pakeke Brinell, nō reira e tino manakohia ana.
He maha ngā mea whakarewa he rahi-waenga ki te rahi, ko ētahi he maha ngā tāne te taumaha, ā, kāore e taea te whakamātautau i runga i te taputapu whakamātautau pakeke o runga. Ko te whakamātautau pakeke tika o ngā mea whakarewa he mea whakamahi i ngā tokotoko whakamātautau whakarewa motuhake, i ngā poraka whakamātautau rānei e piri ana ki ngā mea whakarewa. Heoi, kāore e taea e te pae whakamātautau, e te poraka whakamātautau rānei te whakakapi katoa i te mea whakarewa tonu. Ahakoa he oumu rino rewa kotahi, he rite tonu te tukanga whakarewa me ngā tikanga maimoatanga wera. Nā te rerekētanga nui o te rahi, ka rerekē te tere whakamahana, inā koa te tere whakamatao. He uaua ki te whakarite kia rite te pakeke o ngā mea e rua. Nā tēnei take, he maha ngā kaihoko e aro nui ana, e whakapono ana hoki ki te pakeke o te mea whakarewa tonu. Me whakamahi he taputapu whakamātautau pakeke tika hei whakamātautau i te pakeke o ngā mea whakarewa. Ka whakatauhia tēnei raruraru e te taputapu whakamātautau pakeke Leeb, engari me aro ki te mata o te mea whakarewa i te wā e whakamahia ana te taputapu whakamātautau pakeke Leeb. He whakaritenga kei te taputapu whakamātautau pakeke Leeb mō te taratara o te mata o te mea whakarewa.
Kaiwhakamātautau Pakeke Brinell
Me whakamahi te whakamātautau pakeke Brinell hei whakamātautau i te pakeketanga o ngā whakarewanga rino. Mō ngā whakarewanga rino hina me ngā kōpura matotoru, me whakamahi i ngā tikanga whakamātautau o te kaha 3000kg me te pōro 10mm i ngā wā katoa e taea ana. Mēnā he iti te rahi o te whakarewanga, ka taea hoki te whakamahi i te whakamātautau pakeke Rockwell.
He koretake te hanganga o ngā whakarewa rino, he nui ake ngā kakano, ā, he nui ake te waro, te silicon me ētahi atu poke i te maitai, ā, ka rerekē te pakeketanga i ngā wāhi iti rerekē, i ngā pūwāhi rerekē rānei. He nui ake te rahi o te kōhao o te whakamātautau pakeke Brinell, ā, he nui ake te horahanga kōhao, ā, ka taea te ine i te uara toharite o te pakeketanga rauemi i roto i tētahi whānuitanga. Nō reira, he nui ake te tika o te whakamātautau o te whakamātautau pakeke Brinell, ā, he iti ake te horapa o ngā uara pakeketanga. Ko te uara pakeketanga i inehia he tohu ake i te pakeketanga tuturu o te mea mahi. Nō reira, he whānui te whakamahinga o te whakamātautau pakeke Brinell i roto i te umanga whakarewa.
Te pakeke o Rockwell
E whakamahia whānuitia ana hoki ngā whakamātautau pakeke Rockwell mō te whakamātautau pakeke o te rino maka. Mō ngā mea mahi he kikokore, ki te kore e ranea te wāhi mō te whakamātautau pakeke Brinell, ka taea hoki te whakahaere i te whakamātautau pakeke Rockwell. Mō te rino maka pearlitic, te rino maka matao me te maitai maka, ka taea te whakamahi i te tauine HRB, HRC rānei. Ki te kore e ōrite te rauemi, me ine kia maha ngā pānui, ā, me tango te uara toharite.
Kaiwhakamātautau Pakari o te Takutai
I ētahi wā, mō ētahi whakarewanga he nui ngā āhua, kāore e whakaaetia kia tapahia te tauira, ā, kāore hoki e whakaaetia kia whakarewahia ētahi atu poraka whakamātautau hei whakamātautau i te pakeke. I tēnei wā, ka pāngia te whakamātautau pakeke e ngā uauatanga. Mō tēnei wā, ko te tikanga noa ko te whakamātautau i te pakeke me te taputapu whakamātautau pakeke Shore kawe i runga i te mata maeneene i muri i te otinga o te whakarewanga. Hei tauira, i roto i te paerewa rōra e whakamahia whānuitia ana i roto i te umanga whakarewa, kua whakaritea kia whakamahia te taputapu whakamātautau pakeke Shore hei whakamātautau i te pakeke.
