Mīhini whakamātautau pakeke

Ngā Mahi Matua：

He taputapu whakamātautau pakeke motuhake te XHR-150 Rockwell hardness Tester mō te whakamātautau i ngā rauemi kore-whakarewa, pērā i te kirihou, te rapa mārō, te kapia hangai, ngā rauemi waku me ngā konganuku ngohengohe.

Ka taea e ia te whakamātautau i ngā rauemi e whai ake nei:

1. Whakamātauria ngā kirihou, ngā mea whakahiato me ngā momo rauemi waku.

2. Whakamātauria te pakeke o ngā mea whakarewa ngohengohe me ngā mea ngohengohe kore-whakarewa

Ā Mātou Painga:

1. Ka whakamahia hei whakamātautau ā-ringa, kāore he pūtake hiko, he whānui te whānuitanga o ngā tono, he māmā te whakahaere, ā, he pai te ōhanga me te whai huatanga.

2. He mea hanga te tinana o te waka rererangi ki te rino maka kounga teitei, ā, he mea maka anō hoki i te wā kotahi, me te tukanga tunu peita waka, he āhua porowhita, he ātaahua hoki.

3. Ka pānui tika te mata i te uara pakeke, ā, ka taea te whakauru atu ki ētahi atu pauna Rockwell.

4. Kua whakamahia te miro kore-waku, ā, he teitei te tika o te kaha whakamātautau.

5. Kei roto hoki te pūnaha pare waipēhi tino tika mō te whakarewanga, kāore he turuturu pare, he pumau te uta me te tango. I taua wā, kāore he pānga, ā, ka taea te whakarite i te tere.

6. Ka tutuki te tika ki ngā whakaritenga a GB / T230.2-2018, ISO6508-2 me ASTM E18.
