Izibophelelo zizinto ezibalulekileyo zokunxibelelana ngoomatshini, kwaye umgangatho wazo wobulukhuni yenye yezona zinto zibalulekileyo zokulinganisa umgangatho wazo.
Ngokweendlela ezahlukeneyo zokuvavanya ubulukhuni, iindlela zokuvavanya ubulukhuni zeRockwell, Brinell kunye neVickers zingasetyenziselwa ukuvavanya ubulukhuni bezinto zokubopha.
Uvavanyo lobunzima beVickers luhambelana ne-ISO 6507-1, uvavanyo lobunzima beBrinell luhambelana ne-ISO 6506-1, kwaye uvavanyo lobunzima beRockwell luhambelana ne-ISO 6508-1.
Namhlanje, ndiza kwazisa indlela yobunzima be-micro-Vickers ukulinganisa ukucocwa komphezulu kunye nobunzulu bomaleko ocociweyo wezinto zokubopha emva konyango lobushushu.
Ukuze ufumane iinkcukacha, nceda ujonge umgangatho wesizwe we-GB 244-87 ukuze ufumane imigaqo yomda wokulinganisa ubunzulu bomaleko okhutshwe kwikhabhoni.
Indlela yovavanyo lwe-micro-Vickers yenziwa ngokuhambelana ne-GB/T 4340.1.
Isampulu idla ngokulungiswa ngokuthatha iisampulu, ukuyigaya nokuyipolisha, ize ibekwe kwisixhobo sokuvavanya ubunzima obuncinci ukuze kufunyanwe umgama ukusuka kumphezulu ukuya kwindawo apho ixabiso lobunzima elifunekayo lifikelelwe khona. Amanyathelo athile okusebenza amiselwa linqanaba lokuzenzekelayo kwesi sixhobo sokuvavanya ubunzima esisetyenzisiweyo.
