Ukulungiswa kokuhlolwa kobulukhuni be-rockwell:
qinisekisa ukuthi umhloli wobulukhuni uyafaneleka, bese ukhetha ibhentshi lokusebenzela elifanele ngokwesimo sesampula; Khetha i-indenter efanele kanye nenani lomthwalo eliphelele.
Izinyathelo zokuhlola ubulukhuni be-Rockwell manual HR-150A:
Isinyathelo 1:
Beka isampula ebhentshini lokusebenza, jikelezisa isondo lesandla ukuze uphakamise kancane ibhentshi lokusebenza, bese ucindezela i-indenter phezulu ngo-0.6mm, inkomba encane yedayili yesikhombisi ibhekisela ku-"3", inkomba enkulu ibhekisela kuphawu u-c no-b (okuncane kancane kunedayili kungajikeleziswa kuze kube yilapho kuqondana).
Isinyathelo 2:
Ngemva kokuba indawo yesikhombisi iqondaniswe, ungadonsa isibambo sokulayisha phambili ukuze ufake umthwalo oyinhloko ekhanda lokucindezela.
Isinyathelo 3:
Uma ukujikeleza kwesikhombisi senkomba kuyeka ngokusobala, isibambo sokulayisha singasunduzelwa emuva ukuze kususwe umthwalo oyinhloko.
Isinyathelo 4:
Funda inani lesikali elihambisanayo elivela kusikhombisi. Uma kusetshenziswa i-indenter yedayimane, ukufundwa kuba ngohlamvu olumnyama endandatho engaphandle yedayili;
Uma kusetshenziswa i-indenter yebhola lensimbi, inani lifundwa ngohlamvu olubomvu olusendandatho yangaphakathi yedayela yokufunda.
Isinyathelo 5:
Ngemva kokukhulula isondo lesandla nokwehlisa ibhentshi lokusebenza, ungashukumisa isampula kancane bese ukhetha indawo entsha ukuze uqhubeke nokuhlolwa.
Qaphela: Uma usebenzisa imitha yokuqina ye-HR-150A Rockwell, kubalulekile ukunaka ukugcina imitha yokuqina ihlanzekile futhi ugweme ukungqubuzana nokungqubuzana, ukuze kungathinti ukunemba kokulinganisa.
