Njengoko sonke sisazi, indlela nganye yokuvavanya ubulukhuni, nokuba ngaba iBrinell, iRockwell, iVickers okanye iLeeb hardness tester ephathwayo, inemida yayo kwaye ayinamandla onke. Kwizixhobo zokusebenza zejometri ezinkulu, ezinzima kunye nezingaqhelekanga njengaleyo iboniswe kulo mzekelo ulandelayo, iindlela ezininzi zokuvavanya zangoku zisebenzisa abavavanyi bobulukhuni beLeeb abaphathwayo ukulawula ubulukhuni babo.
Indlela yokulinganisa i-dynamic ye-Leeb hardness tester inezinto ezininzi ezichaphazela ukuchaneka kobunzima bayo: njenge: imodyuli ye-elastic, ukusetyenziswa kwentloko yebhola, i-workpiece surface roughness, i-curvature radius, i-surface hardened umaleko ubunzulu, njl. Ukuba ubunzima bufuna ukuchaneka okuphezulu, kufuneka sikhethe njani umvavanyi wobulukhuni?
Olu hlobo lokusebenzela olunzima kwinkqubo yovavanyo lomvavanyi wobulukhuni oluqhelekileyo, ngaphambi kokuba uvavanyo lokulayishwa kunye nokukhulula umvavanyi wobulukhuni, kunye nokukhulula umvavanyi wobulukhuni kuya kuzisa umthwalo omkhulu womsebenzi kwinkqubo yokusebenza, ngoko sikhetha njani umvavanyi wobulukhuni? Oku kulandelayo kuncoma ukusetyenziswa komhloli wobunzima kunye nesakhiwo sokuphakamisa intloko ukugqiba yonke inkqubo yokuvavanya. Njengoko kubonisiwe ngezantsi:
Esi sisombululo sokuvavanya ubulukhuni sinokuqonda uvavanyo lwe-Rockwell ubulukhuni / i-Vickers kunye novavanyo lobulukhuni be-Brinell ngokwemigangatho yokuvavanya ubulukhuni (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, njl.), kunye nokuhlangabezana novavanyo oluchanekileyo oluphezulu kunye neemfuno ezisebenzayo zemveliso yezinto zokusebenza ezinzima.
Intloko ngokuzenzekelayo iphakamisa umhloli wobunzima ine-workbench esisigxina, enciphisa impazamo ebangelwa yi-screw kunye nokuphakanyiswa kwe-workbench ukuchaneka komlinganiselo wobunzima. Ibhentshi yokusebenzela inkulu ngokobungakanani kwaye inokwamkela iiweyishi ezinkulu zokusebenza. Umlinganiselo weqhosha elinye unciphisa kakhulu impazamo yovavanyo kunye nomsebenzi womvavanyi, olungele kwaye ukhawuleza.
