Kumakhasimende amaningi anezidingo eziphakeme zokunemba kwabahloli bokuqina, ukulinganiswa kwabahloli bokuqina kubeka izimfuno eziqinile kumabhulokhi wobulukhuni. Namuhla, ngijabulele ukwethula uchungechunge lwamabhulokhi okuqina Ekilasi A.—I-Rockwell hardness blocks, Vickers hardness blocks, Brinell Hardness blocks, HRA, HRB, HRC, HRE HRR, HV, HBW njll.
Amabhulokhi okuqina ekilasi A angaphansi kwezidingo eziqinile kakhulu mayelana namasu okucubungula, ukwelashwa kwendawo, nezinqubo zokwelashwa kokushisa. Inqubo yokukhiqiza yala mabhuloki okuqina ihilela izindlela ezithuthukisiwe zemishini. Kusetshenziswa izikhungo zemishini ezisezingeni eliphezulu ze-CNC ukuze kuqinisekiswe ukuthi ubukhulu bamabhulokhi obuqinile buhlangabezana namazinga anembe ngokwedlulele. Ipharamitha yokusika ngayinye ilungiswa ngokucophelela ukuze kuncishiswe noma yimaphi amaphutha angaba khona wobukhulu.
Esicini sokwelashwa kwendawo, kusetshenziswa izindlela ezikhethekile zokuqeda ingaphezulu. Ukupholisha ngamakhemikhali kanye nokugqinqguza okunembayo kuyenziwa ukuze kwakhiwe indawo enokumahhadla okuphansi kakhulu. Lokhu akunciphisi nje kuphela ukuphazamiseka kokungalungi kwendawo ngesikhathi senqubo yokukala ubulukhuni kodwa futhi kuthuthukisa ukunamathela phakathi kwe-indenter yomhloli wokuqina kanye nobuso bebhulokhi yokuqina, okuqinisekisa imiphumela yokulinganisa enembe kakhudlwana.
Inqubo yokwelapha ukushisa kwamabhulokhi wokuqina we-Class A nayo ilawulwa ngokucophelela. Kusetshenziswa amaziko okushisa asezingeni eliphezulu anezinhlelo eziqondile zokulawula izinga lokushisa. Phakathi nenqubo yokwelapha ukushisa, izinga lokushisa, isikhathi sokubamba, kanye nezinga lokupholisa konke kulawulwa ngokuqinile ngokuya ngejika lenqubo ethile. Lokhu kuqinisekisa ukuthi isakhiwo sangaphakathi se-hardness block siyafana futhi sizinzile, sinciphisa ngokuphumelelayo ukucindezeleka kwangaphakathi ngaphakathi kwezinto.
Ngenxa yalezi zinqubo eziqinile, ukungaqiniseki kokulinganisa kwamabhulokhi wokuqina we-Class A kwehliswe kakhulu, futhi ukufana kwawo kuphakeme ngokuphawulekayo uma kuqhathaniswa nezinye izinhlobo zamabhulokhi okuqina. Zihlinzeka ngesisekelo esithembeke kakhudlwana sokulinganisa abahloli bokuqina, okuvumela abahloli bokuqina ukuze bathole ukunemba okuphezulu nokuzinza ezilinganisweni zabo. Kungakhathaliseki ukuthi kusekukhiqizweni kwezimboni, ekulawuleni ikhwalithi kumalabhorethri, noma emikhakheni yocwaningo lwesayensi, amabhulokhi wokuqina weSigaba A adlala indima ebalulekile nebalulekile, asize ochwepheshe bathole idatha yokulinganisa ubulukhuni enembe kakhudlwana nethembekile.
Ngokukhetha amabhlogo wokuqina we-Class A, amakhasimende angaba nokuzethemba okuphelele ekulinganisweni kwabahloli bokuqina, aqinisekise ukuthi imiphumela yawo yokuhlola ubulukhuni inembile futhi ayiguquki, futhi ngaleyo ndlela anikeze ukusekelwa okuqinile kokulawulwa kwekhwalithi nokuthuthukiswa komkhiqizo wemikhiqizo yawo.
