Kumakhasimende amaningi anezidingo eziphezulu zokunemba kwabahloli bokuqina, ukulinganiswa kwabahloli bokuqina kubeka izidingo eziqinile kumabhulokhi obulukhuni. Namuhla, ngiyajabula ukwethula uchungechunge lwamabhulokhi obulukhuni be-Class A.—Amabhulokhi obulukhuni be-Rockwell, amabhulokhi obulukhuni be-Vickers, amabhulokhi obulukhuni be-Brinell, i-HRA, i-HRB, i-HRC, i-HRE HRR, i-HV, i-HBW njll.
Amabhulokhi obulukhuni be-Class A angaphansi kwezidingo eziqinile kakhulu maqondana namasu okucubungula, ukwelashwa kwendawo, kanye nezinqubo zokwelashwa kokushisa. Inqubo yokukhiqiza yala mabhulokhi obulukhuni ihilela izindlela zokugaya ezithuthukisiwe. Izikhungo zokugaya ze-CNC ezisezingeni eliphezulu ziyasetshenziswa ukuqinisekisa ukuthi ubukhulu bamabhulokhi obulukhuni buhlangabezana nezindinganiso ezinembile kakhulu. Ipharamitha ngayinye yokusika ilungiswa ngokucophelela ukuze kuncishiswe noma yimaphi amaphutha angaba khona ngobukhulu.
Esicini sokwelashwa kobuso, kusetshenziswa amasu akhethekile okuqeda ubuso. Ukupholisha ngamakhemikhali kanye nokufaka ngokunemba kwenziwa ukudala ubuso obunobulukhuni obuphansi kakhulu. Lokhu akugcini nje ngokunciphisa ukuphazamiseka kokungalingani kobuso ngesikhathi senqubo yokulinganisa ubulukhuni kodwa futhi kuthuthukisa ukunamathelana phakathi kwe-indenter yesihloli sobulukhuni kanye nobuso bebhlokhi yobulukhuni, okuqinisekisa imiphumela yokulinganisa enembile kakhulu.
Inqubo yokwelapha ukushisa yamabhulokhi obulukhuni be-Class A nayo ilawulwa ngokucophelela. Kusetshenziswa izitofu zokwelapha ukushisa ezithuthukisiwe ezinezinhlelo zokulawula izinga lokushisa eziqondile. Ngesikhathi senqubo yokwelapha ukushisa, izinga lokushisa, isikhathi sokubamba, kanye nezinga lokupholisa konke kulawulwa ngokuqinile ngokwendlela ethile yenqubo. Lokhu kuqinisekisa ukuthi isakhiwo sangaphakathi sebhulokhi lobulukhuni siyafana futhi sizinzile, okunciphisa ngempumelelo ukucindezeleka kwangaphakathi ngaphakathi kwezinto.
Ngenxa yalezi zinqubo eziqinile, ukungaqiniseki kokulinganisa kwamabhulokhi obulukhuni be-Class A kuncishiswe kakhulu, futhi ukufana kwawo kuphakeme kakhulu uma kuqhathaniswa nezinye izinhlobo zamabhulokhi obulukhuni. Anikeza isisekelo esithembeke kakhulu sokulinganiswa kwabahloli bobulukhuni, okwenza abahloli bobulukhuni bakwazi ukufeza ukunemba okuphezulu nokuzinza ekulinganisweni kwabo. Kungakhathaliseki ukuthi kukhiqizweni kwezimboni, ekulawulweni kwekhwalithi emalabhorethri, noma emikhakheni yocwaningo lwesayensi, amabhulokhi obulukhuni be-Class A adlala indima ebalulekile nebalulekile, esiza ochwepheshe ukuthola idatha yokulinganisa ubulukhuni enembile nethembekile.
Ngokukhetha amabhlogo obulukhuni beKlasi A, amakhasimende angaba nokuqiniseka okugcwele ekulinganisweni kwabahloli babo bobulukhuni, aqinisekise ukuthi imiphumela yabo yokuhlola ubulukhuni inembile futhi iyahambisana, ngaleyo ndlela anikeze ukwesekwa okuqinile kokulawulwa kwekhwalithi kanye nokuthuthukiswa komkhiqizo wemikhiqizo yawo.
