Taw qhia rau kev siv Leeb hardness tester

(1) Cov khoom yuav raug kuaj pom yuav tsum muab tso rau hauv av thiab yuav tsum ruaj khov yam tsis muaj kev co. Qhov chaw kuaj pom yuav tsum tsis txhob raug tshem tawm hauv huab cua. Kev them nyiaj yug blocks yuav tsum tau ntxiv yog tias tsim nyog.
(2) Qhib lub hardness tester → khoom teeb tsa ntawm cov khoom → hardness value setting (HRCHRBHB) ​​→ hardness detection direction setting → start hardness detection.
(3) Nias lub cuab yeej cuam tshuam rau saum npoo los ntsuas thiab nias nws. Tom qab 1 vib nas this, nias lub tog raj kheej me me ntawm lub hardness tester. Tus nqi hardness yuav raug tso tawm kom pom. Thaum lub sij hawm tus txheej txheem no, tus neeg teb xov tooj yuav tsum muab cov cuab yeej cuam tshuam. ruaj khov, thiab cov kev taw qhia yuav tsum yog perpendicular mus rau qhov chaw ntsuas.
(4) Txhua qhov kev xeem yuav tsum tau kuaj tsawg kawg yog 3 lub ntsiab lus, thiab qhov kev ncua deb ntawm ob lub ntsiab lus xeem yuav tsum siab dua lossis sib npaug li 3 hli. Tom qab qhov kev xeem, tus nqi nruab nrab yog muab raws li qhov hardness ntawm ib feem, thiab sau tseg, thiab tom qab ntawd mus rau ntu tom ntej rau kev sim.
(5) Cov txiaj ntsig kev xeem tau muab piv nrog cov kev xav tau ntawm cov khoom. Yog tias qhov yuav tsum tau ua tiav, cov khoom raug suav tias tsim nyog thiab xa mus rau cov txheej txheem tom ntej; yog tias nws ua tsis tau, nws raug xa mus rau qhov chaw nyob ib leeg thiab cov ntawv xeem tau raug kaw.
