Kukho iinkampani ezininzi ezithengisa izixhobo zokuvavanya ubunzima beRockwell kwimarike okwangoku. Ungazikhetha njani izixhobo ezifanelekileyo? Okanye, singenza njani ukhetho olufanelekileyo ngeemodeli ezininzi kangaka ezikhoyo?
Lo mbuzo uhlala ukhathaza abathengi, njengoko uluhlu olubanzi lweemodeli kunye namaxabiso ahlukeneyo enza kube nzima ukugqiba. Apha ngezantsi kukho isikhokelo esifutshane sokukunceda ukhethe isixhobo sokuvavanya ubunzima seRockwell esifanelekileyo.
Izixhobo zokuvavanya ubulukhuni zeRockwell zezona zixhobo zisetyenziswa kakhulu kuvavanyo lobulukhuni. Ngenxa yeenzuzo zazo ezifana nokusebenza okulula, isantya sokuvavanya ngokukhawuleza, iimfuno eziphantsi zezinto zokusebenza, kunye neemfuno ezincinci zezakhono kubaqhubi, zisetyenziswa kakhulu kwiifektri zonyango lobushushu, iiworkshops, iiyunivesithi, amaziko ophando, amasimi eenqwelo moya njl.njl.
1. Umgaqo weRockwell Hardness Testers
Abavavanyi bobulukhuni baseRockwell basebenza ngokomgaqo wokulinganisa ubunzulu. Ukuthetha nje: sebenzisa amaxabiso ahlukeneyo amandla kwii-indenter ezahlukeneyo, yenza ii-indentations, kwaye ufunde ngokuthe ngqo ixabiso lobulukhuni.
2. Uhlu lweeRockwell Hardness Testers
1) Uhlulwe ngokweSikali

6) Ihlelwe ngokweNqanaba lokuZenzekelayo
6.1) Uvavanyo loBulukhuni beRockwell oluSebenzisa ngesandla
Amandla okuqala ovavanyo alayishwa ngesandla; amandla ovavanyo oluphambili alayishwa aze akhutshwe ngesandla.
Ukusebenza: ukudibana kwe-indenter nesampulu, isalathisi esikhulu sijika izangqa ezintathu ezipheleleyo, sitsale ngesandla isiphatho sokulayisha ukuze sisebenzise amandla, uze utyhale isiphatho ukuze sikhuphe, funda ixabiso lesiphawuli, isisombululo yi-0.5HR.
6.2) Isivavanyeli soBulukhuni beRockwell yoMbane
Amandla okuqala ovavanyo alayisha ngesandla; amandla ovavanyo aphambili alayisha, ahlala, aze akhuphe ngokuzenzekelayo (kufuneka ucinezele iqhosha elithi "Layisha"; ixesha lokuhlala liyalungiseka)
Amanyathelo okusebenza: ukudibana kwe-indenter nesampulu, isalathisi esikhulu sijika izangqa ezipheleleyo ezintathu, ucinezele iqhosha elithi “Layisha”, ulayishe ngokuzenzekelayo, uhlale, kwaye ukhuphe; funda ixabiso lesalathisi, isisombululo se-0.1HR.
6.3) Isivavanyeli soBulukhuni beDijithali seRockwell: iintlobo ezimbini
6.3.1) Amandla okuqala ovavanyo alayisha ngesandla; amandla ovavanyo aphambili alayisha, ahlala, aze akhuphe ngokuzenzekelayo.
Ukusebenza: unxibelelwano lwe-indenter nesampulu, ukufikelela kwibha yenkqubela phambili KULUNGILE, umthwalo ozenzekelayo, ukuhlala, kunye nokukhulula, ixabiso lobulukhuni liboniswa ngokuzenzekelayo, isisombululo yi-0.1HR.
6.3.2) Amandla okuqala ovavanyo alayisha ngokuzenzekelayo; amandla ovavanyo aphambili alayisha, ahlala, aze akhuphe ngokuzenzekelayo.
ukusebenza: xa umgama phakathi kwe-indenter kunye nesampuli uyi-0.5mm, cofa iqhosha elithi “Layisha”, ii-indenter ziyawa ngokuzenzekelayo, zilayishe, zihlale, zikhuphe, ii-indenter ziphakamisa ngokuzenzekelayo, ixabiso lobulukhuni liboniswa ngokuzenzekelayo, isisombululo 0.1HR.
6.4) Isivavanyeli soBulukhuni beRockwell esiZenzekelayo ngokupheleleyo (ukuze sithethe: “Isivavanyeli soBulukhuni beRockwell esiZenzekelayo ngokupheleleyo – Qonda kwisivakalisi esinye”)
Iimpawu: ukuphakamisa izikrufu ngokuzenzekelayo, ukukhetha amandla ovavanyo oluzenzekelayo, umthwalo wokuqala nowokuqala wamandla ovavanyo oluzenzekelayo, ukukhulula ngokuzenzekelayo, kunye nokubonisa ixabiso lobunzima oluzenzekelayo.
Ukusebenza: ukusebenza ngeqhosha elinye, cofa iqhosha lokuqala; ibhentshi yokusebenzela iphakama ngokuzenzekelayo, emva kokuba isampuli iqhagamshelane ne-indenter, ilayisha ngokuzenzekelayo, ikhuphe, ixabiso lobunzima liboniswe ngokuzenzekelayo.
(Ibhentshi yokusebenza iphakamisa ngokuzenzekelayo ngaphandle kwemiqathango yokuphakama, ngaphandle kokujikeleza ngesandla kwe-screw swing.)
7) Ihlelwe ngokwendlela yokwenza ngokwezifiso
oomatshini abaqhelekileyo; oomatshini abenzelwe wena; abavavanyi bobulukhuni kwi-intanethi, njl.
