Joalo ka ha bohle re tseba, mokhoa o mong le o mong oa teko ea boima, ebang ke Brinell, Rockwell, Vickers kapa portable Leeb hardness tester, e na le mefokolo ea eona mme ha e matla 'ohle. Bakeng sa li-workpieces tse kholo, tse boima le tse sa tloaelehang tsa geometri tse kang tse bontšitsoeng mohlaleng o latelang, mekhoa e mengata ea tlhahlobo ea morao-rao e sebelisa liteko tse nkehang tsa Leeb hardness ho laola boima ba tsona.
Mokhoa o matla oa ho lekanya oa teko ea boima ba Leeb o na le lintlha tse ngata tse amang ho nepahala ha boima ba eona: tse kang: modulus ea lintho tse bonahalang, ho sebelisoa ha hlooho ea bolo, ho rarahana ha workpiece, radius ea curvature, botebo bo thata ba lera, joalo-joalo Ha ho bapisoa le mekhoa ea tekanyo e tsitsitseng ea Brinell, Rockwell le Vickers, phoso e batla e le kholoanyane. Haeba boima bo hloka ho nepahala ho phahameng, re lokela ho khetha tester ea boima joang?
Mofuta ona oa mosebetsi o boima ka mokhoa o tloaelehileng oa ho lekoa ka thata-thata, pele teko loading le laolla ea tester boima, le ho laolla ea tester boima tla tlisa mosebetsi o moholo ka tshebetso tshebetso, kahoo re khetha mohlahlobisisi boima? Lintlha tse latelang li khothalletsa tšebeliso ea tester ea boima bo nang le mohaho oa ho phahamisa hlooho ho phethahatsa ts'ebetso eohle ea teko. Joalokaha ho bontšitsoe ka tlase:
Tharollo ena ea ho lekola boima ba 'mele e ka lemoha tlhahlobo ea ho thatafala ha Rockwell/Vickers le Brinell ea ho thatafala ho latela litekanyetso tsa teko ea boima (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, joalo-joalo), 'me ea kopana le tlhahlobo e nepahetseng e phahameng le litlhoko tse sebetsang tsa tlhahiso ea lisebelisoa tse boima tsa mosebetsi.
The head automatic lifting hardness tester e na le benche e tsitsitseng ea mosebetsi, e fokotsang phoso e bakoang ke screw le ho phahamisoa ha workbench ho nepahala ha tekanyo ea boima. Benche ea mosebetsi e kholo ka boholo 'me e khona ho amohela lisebelisoa tse kholo tsa boima. Tekanyo ea konopo e le 'ngoe e fokotsa haholo phoso ea teko le mosebetsi oa tester, e leng bonolo ebile e potlakile.
