Njengoba sonke sazi, indlela ngayinye yokuhlola ubulukhuni, noma ngabe i-Brinell, i-Rockwell, i-Vickers noma i-Leeb hardness tester, inemikhawulo yayo futhi ayinamandla onke. Ezindaweni zokusebenza zejiyomethri ezinkulu, ezisindayo nezingajwayelekile njengalena eboniswe esibonelweni esilandelayo, izindlela eziningi zokuhlola zamanje zisebenzisa izihloli zokuqina ze-Leeb eziphathwayo ukuze zilawule ubulukhuni bazo.
Indlela yokulinganisa eguquguqukayo yesihloli sobulukhuni be-Leeb inezici eziningi ezithinta ukunemba kokuqina kwayo: njengalezi: imodulus enwebekayo yezinto ezibonakalayo, ukusetshenziswa kwekhanda lebhola, ukuhwaqeka kwendawo yokusebenza, i-curvature radius, ukujula kongqimba oluqinile, njll. Uma kuqhathaniswa nezindlela zokulinganisa ezimile zikaBrinell, Rockwell kanye noVickers, iphutha likhulu kakhulu uma kuqhathaniswa. Uma ubulukhuni budinga ukunemba okuphezulu, kufanele sikhethe kanjani umhloli wokuqina?
Lolu hlobo lomsebenzi olusindayo ohlelweni lokuhlola ubulukhuni obujwayelekile, ngaphambi kokulayisha nokuthulula umhloli wokuqina, futhi ukuthulula umhloli wokuqina kuzoletha umthwalo omkhulu womsebenzi ohlelweni lokusebenza, ngakho-ke sikhetha kanjani umhloli wokuqina? Okulandelayo kuncoma ukusetshenziswa komhloli wokuqina ngesakhiwo sokuphakamisa ikhanda ukuze kuqedelwe yonke inqubo yokuhlola. Njengoba kuboniswe ngezansi:
Lesi sixazululo sokuhlola ubulukhuni singakwazi ukuhlola ubulukhuni be-Rockwell/Vickers kanye nokuhlolwa kokuqina kwe-Brinell ngokuvumelana nezindinganiso zokuhlola ubulukhuni (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, njll.), futhi sihlangabezane nokuhlolwa okunembayo okuphezulu kanye nezidingo zokukhiqiza ezisebenzayo zezingcezu zokusebenza ezinzima.
Isihloli sokuqina sokuqina kwekhanda esiphakamisa ngokuzenzakalela sinebhentshi lokusebenza elingaguquki, elinciphisa iphutha elibangelwa isikulufu nokuphakanyiswa kwebhentshi lokusebenzela ekunembeni kokulinganisa ubulukhuni. Ibhentshi lokusebenzela likhulu ngosayizi futhi lingakwazi ukumumatha ama-workpiece amakhulu okukala. Ukulinganisa inkinobho eyodwa kunciphisa kakhulu iphutha lokuhlola nomsebenzi womhloli, okulula futhi okusheshayo.
