Isivavanyeli sobulukhuni se-Superficial Rockwell luhlobo lwesivavanyeli sobulukhuni se-Rockwell. Sisebenzisa amandla ovavanyo amancinci. Xa kuvavanywa ezinye izinto ezincinci nezincinci, ukusebenzisa isivavanyeli sobulukhuni se-Rockwell kuya kukhokelela kumaxabiso angachanekanga okulinganisa. Singasebenzisa isivavanyeli sobulukhuni se-Superficial Rockwell. Isivavanyeli sobulukhuni sinokusetyenziselwa ukulinganisa izinto zokusebenza ezineeleya eziqinileyo ze-Superficial.
Umgaqo wayo wokuvavanya ufana nqwa nalowo wokuvavanya ubunzima beRockwell. Umahluko kukuba amandla okuqala okuvavanya yi-3KG, ngelixa amandla okuqala okuvavanya ubunzima beRockwell eqhelekileyo yi-10KG.
Inqanaba lovavanyo lobunzima beRockwell elingaphezulu: 15KG, 30KG, 45KG
I-indenter esetyenzisiweyo kwi-Superficial Rockwell hardness tester iyahambelana ne-Rockwell hardness tester.:
1. 120 di-egree diamond cone indenter
2. 1.5875 i-indenter yebhola yentsimbi
I-Rockwell Engaphezuluisikali sokulinganisa ubulukhuni bomvavanyi:
HR15N, HR30N, HR45N, HR15T, HR30T, HR45T
(Isikali sika-N silinganiswa nge-indenter yedayimani, kwaye isikali sika-T silinganiswa nge-indenter yebhola yentsimbi)
Ubulukhuni bubonakaliswanjenge: ixabiso lobulukhuni kunye nesikali seRockwell, umzekelo: 70HR150T
I-15T ithetha i-indenter yebhola yentsimbi enamandla ovavanyo apheleleyo e-147.1N (15 kgf) kunye ne-indenter eyi-1.5875
Ngokusekelwe kwi-cha engentlaubuhlanga, i-Superficial Rockwell inezi nzuzo zilandelayo:
1. Ekubeni inezimbiniIintloko zoxinzelelo, ifanelekile kwizixhobo zesinyithi ezithambileyo neziqinileyo.
2. Amandla ovavanyo yi-smilunge kakhulu kuneyomvavanyi wobunzima beRockwell, kwaye umonakalo ongaphezulu wesixhobo somsebenzi mncinane kakhulu.
3. IiForc zovavanyo ezincinciingathatha indawo yesivavanyeli sokuqina kweVickers ngokuyinxenye, esingabizi kakhulu kwaye sifikelelekayo.
4. Inkqubo yovavanyo ikhawuleza kwaye umsebenzi ogqityiweyo unokubonwa ngokufanelekileyo.
