Umthungo othe ngqo odityanisiweyo wombhobho wokucima umphezulu kunye nonyango olushushu ludla ngokuqhutywa ngokufudumeza ngokungenisa okanye ukufudumeza ilangatye.Ezona parameters zobugcisa bubulukhuni bomphezulu, ubulukhuni bendawo kunye nobunzulu obusebenzayo bomaleko.Uvavanyo lobulukhuni lunokusebenzisa iVickers tester yokuqina, iRockwell okanye umvavanyi wobulukhuni beRockwell.Xa umphezulu wonyango lobushushu bomgangatho owenziweyo ungqindilili, umvavanyi wobulukhuni beRockwell nawo unokusetyenziswa.

Ukuba ubulukhuni bendawo bendawo kufuneka buphakame, ukucinywa kwe-induction kunye nezinye iindlela zingasetyenziselwa ukucima unyango lobushushu bendawo.Umthungo onjalo umbhobho odityanisiweyo udla ngokuphawulwa kunye nendawo yokucima ubushushu bendawo kunye nexabiso lobulukhuni bendawo kumzobo.Umthungo othe ngqo wovavanyo lobulukhuni bombhobho odityanisiweyo kufuneka lwenziwe kwindawo echongiweyo.

Amanani amathathu obunzima beVickers, i-Rockwell kunye ne-Surface Rockwell inokuguqulwa ngokulula komnye nomnye kwaye iguqulelwe kwimigangatho, imizobo okanye ubulukhuni obufunwa ngabasebenzisi.
