Iimpawu kunye nokusetyenziswa komvavanyi wobulukhuni beRockwell

Uvavanyo lokuvavanya ubulukhuni beRockwell yenye yeendlela ezintathu eziqhele ukusetyenziswa zovavanyo lokuqina.

Iimpawu ezithile zezi zilandelayo:

1) I-Rockwell hardness tester ilula ukusebenza kune-Brinell kunye ne-Vickers tester hardness , inokufundwa ngokuthe ngqo , izisa ukusebenza kakuhle okuphezulu.

2) Xa kuthelekiswa novavanyo lobulukhuni beBrinell, ukunyanzeliswa kuncinci kunomnye we-Brinell tester hardness, ngoko ke akukho monakalo kumphezulu we-workpiece, efanelekileyo ngakumbi ukufumanisa iindawo ezigqityiweyo zezixhobo zokusika, ukubumba, izixhobo zokulinganisa. , izixhobo, njl.

3 ) Ngenxa yamandla okubona kwangaphambili kwe-Rockwell hardness tester, impembelelo yokunganyaniseki kwendawo encinci kwixabiso lobulukhuni ingaphantsi kweBrinell kunye neVickers, kwaye ifaneleke ngakumbi ukuveliswa kobuninzi bomatshini kunye ne-metallurgical processing thermal kunye ne-semi- ukuhlolwa kwemveliso egqityiweyo okanye egqityiweyo.

I-4) Inomthwalo omncinci wokuvavanya ubulukhuni be-Rockwell ekuvavanyeni, ingasetyenziselwa ukuvavanya ubulukhuni bomaleko obunzima obunzima okanye umphezulu wokugquma.
