Njengemishini yokuhlola ubulukhuni ekhethekile yezinto zokusebenza ezinkulu emkhakheni wokuhlola wezimboni,Uhlobo lwesangoUmhloli wobulukhuni beRockwell udlala indima ebalulekile ekulawuleni ikhwalithi yemikhiqizo emikhulu yensimbi efana namasilinda ensimbi. Inzuzo yayo eyinhloko yikhono layo lokuhlangabezana ngokunembile nezidingo zokulinganisa zezingxenye ezinkulu zomsebenzi, ikakhulukazi zezingxenye ezikhethekile zomsebenzi ezifana namasilinda ensimbi, anezindawo ezigobile, amavolumu amakhulu kanye nesisindo esindayo. Idlula imikhawulo yabahloli bobulukhuni bendabuko ngobukhulu kanye nesisindo sezingxenye zomsebenzi.
Ngokuphathelene nomklamo wesakhiwo,Uhlobo lwesangoAbahloli bobulukhuni beRockwell bavame ukusebenzisa isitebeleUhlobo lwesangoisakhiwo sohlaka, esinomthamo owanele wokuthwala kanye nokuqina, futhi esingamukela kalula izingcezu zomsebenzi zesilinda sensimbi ezinobubanzi obukhulu nobude obude. Isingcezu somsebenzi asidingi ukuphathwa okuyinkimbinkimbi noma ukulungiswa okuqinile lapho sihlolwa, futhi singabekwa ngqo epulatifomu yokuhlola. Indlela yokulinganisa elungisekayo yemishini ivumelana ne-radian yobuso obugobile besilinda sensimbi, iqinisekisa ukuthi i-indenter inamathele ngokuqondile ebusweni besingcezu somsebenzi, futhi igweme amaphutha okuhlola abangelwa ukuma okungajwayelekile kwesingcezu somsebenzi.
Umsebenzi "wokuhlola okusemugqeni" uyisici sawo esiyinhloko. Emugqeni wokukhiqiza wezinto zokusebenza ezifana namasilinda ensimbi,Uhlobo lwesangoUmhloli wobulukhuni beRockwell angafakwa enkambisweni yokukhiqiza ezenzakalelayo. Ngokusebenzisa ukulawulwa kokuxhumanisa nomugqa wokukhiqiza, ukuhlolwa kobulukhuni besikhathi sangempela kwezingxenye zokusebenza ngesikhathi sokucubungula kuyenzeka. Isibonelo, ngemuva kwezinqubo ezibalulekile ezifana nokugoqa isilinda sensimbi nokwelashwa kokushisa, imishini ingaqeda ngokushesha ukuhlolwa kobulukhuni ngaphandle kokudlulisela ingxenye yokusebenza endaweni yokuhlola engaphandle komugqa. Lokhu akugcini nje ngokunciphisa izindleko zokulahlekelwa nesikhathi enkambisweni yokuphathwa kwezingxenye zokusebenza, kodwa futhi kunganikeza impendulo ngesikhathi esifanele ukuthi ubulukhuni bomkhiqizo buyahlangabezana yini namazinga, kwenze kube lula umugqa wokukhiqiza ukulungisa amapharamitha enqubo ngesikhathi sangempela nokuqinisekisa ukuzinza kwekhwalithi yomkhiqizo emthonjeni.
Ngaphezu kwalokho, i-Uhlobo lwesangoUmhloli wobulukhuni waseRockwell uhlonyiswe ngenzwa yokunemba okuphezulu kanye nesistimu yokucubungula idatha ehlakaniphile, engabonisa inani lobulukhuni ngokushesha ngemva kokuhlolwa, futhi isekele ukugcinwa kwedatha, ukulandeleka kanye nokuhlaziywa, ihlangabezane nezidingo zokurekhoda nokuphatha idatha yekhwalithi ekukhiqizweni kwezimboni. Kungakhathaliseki ukuthi isetshenziselwa ukuhlolwa kwefektri kweziqukathi ezinomfutho ophezulu njengezilinda zegesi yemvelo kanye nezilinda zemikhumbi yomfutho, noma ukuhlolwa kwesampula yokusebenza kwezingxenye ezinkulu zensimbi ezakhiwe, inganikeza isiqinisekiso esithembekile sokulawulwa kwekhwalithi yobulukhuni bezingxenye zokusebenza ezinkulu ngezici zayo eziphumelelayo, ezinembile nezilula.Uhlobo lwesangoUmhloli wokuqina kweRockwell usebenzisa izikali zeRockwell (ezinesisindo esingu-60, 100 kanye no-150kgf ngokulandelana) kanye ne-superifiIzikali ze-cial Rockwell (ezinemithwalo engu-15, 30 kanye no-45kgf ngokulandelana) zokuhlola. Ngesikhathi esifanayo, ingafakelwa ngokuzithandela i-Brinell load HBW. Yamukela isakhiwo sokulawula umthwalo weseli, futhi inzwa yamandla enembile kakhulu iqinisekisa imiphumela yokuhlola enembile nezinzile. Isebenza ngesikrini sokuthinta sekhompyutha yezimboni eyakhelwe ngaphakathi, futhi inemisebenzi yokucubungula idatha kanye nokuthumela idatha.
LokhuUhlobo lwesangoUmhloli wobulukhuni beRockwell angaqedela inqubo yokuhlola ngokuzenzakalelayo ngokhiye owodwa. Lo mshini ufeza inqubo yokuhlola "ezenzakalelayo ngokugcwele". Umsebenzisi udinga kuphela ukubeka umsebenzi esiteji, akhethe isikali sokuhlola esidingekayo bese echofoza inkinobho yokuqala. Kusukela ekulayisheni kuya ekutholeni inani lobulukhuni, akukho ukungenelela komuntu phakathi nenqubo. Ngemva kokuba ukuhlolwa sekuqediwe, ikhanda lokulinganisa lizobuyela ngokuzenzakalelayo endaweni yokuqala, okulula ukuthi umsebenzisi athathe indawo yomsebenzi.
Namuhla sithole ucingo oluvela kumakhasimende adinga ukuhlola ubulukhuni bensimbi ephonswe. Kodwa-ke, imvamisa yokusetshenziswa ayiphezulu, futhi isidingo sobulukhuni asiphezulu. Lo mhloli wobulukhuni weRockwell ungasetshenziswa futhi ukuhlola i-HRB bese uyiguqula ibe yi-Brinell hardness value HBW.
