Kubathengi abaninzi abaneemfuno eziphezulu zokuchaneka kwabavavanyi bobulukhuni, ukulinganiswa kwabavavanyi bobulukhuni kubeka iimfuno ezingqongqo kwiibhloko zobunzima. Namhlanje, ndiyavuya ukwazisa uluhlu lweebhloko zobunzima beKlasi A.-Iibhloko zokuqina ze-Rockwell, iibhloko zokuqina ze-Vickers, iibhloko ze-Brinell Hardness, i-HRA, i-HRB, i-HRC, i-HRE HRR, i-HV, i-HBW njl.
Iibhloko zobunzima beKlasi A zixhomekeke kwiimfuno ezingqongqo kakhulu ngokweendlela zokulungisa, unyango olungaphezulu, kunye neenkqubo zokunyanga ubushushu. Inkqubo yokwenziwa kwezi bloko zobulukhuni ibandakanya iindlela eziphambili zomatshini. Amaziko omatshini akumgangatho ophezulu we-CNC aqeshiwe ukuqinisekisa ukuba imilinganiselo yeebhloko zobunzima ihlangabezana nemigangatho echanekileyo kakhulu. Iparameter nganye yokusika ihlengahlengiswa ngononophelo ukuze kuncitshiswe naziphi na iimpazamo ezinobungakanani obunokwenzeka.
Kwinkalo yonyango lomphezulu, iindlela ezikhethekileyo zokugqiba umphezulu zisetyenziswa. Ukupholishwa kweekhemikhali kunye nokuchaneka kwe-lapping kuqhutyelwa ukudala umphezulu kunye noburhabaxa obuphantsi kakhulu. Oku akugcini nje ukunciphisa ukuphazamiseka kokungahambi kakuhle kwendawo ngexesha lenkqubo yokulinganisa ubulukhuni kodwa kwandisa ukunamathela phakathi kwe-indenter yomhloli wobunzima kunye nomphezulu webhloko yobunzima, ukuqinisekisa iziphumo ezichanekileyo zokulinganisa.
Inkqubo yokunyanga ubushushu beebhloko zobunzima beKlasi A ikwalawulwa ngobuchule. Iziko lonyango oluphezulu oluneenkqubo ezichanekileyo zokulawula ubushushu zisetyenziswa. Ngexesha lenkqubo yokunyanga ubushushu, izinga lokushisa, ixesha lokubamba, kunye nesantya sokupholisa zonke zilawulwa ngokungqongqo ngokwendlela ethile yenkqubo. Oku kuqinisekisa ukuba isakhiwo sangaphakathi sebhloko yobunzima siyafana kwaye sizinzile, sinciphisa ngokufanelekileyo uxinzelelo lwangaphakathi ngaphakathi kwezinto.
Ngombulelo kwezi nkqubo zingqongqo, ukungaqiniseki komlinganiselo weebhloko zobunzima beKlasi A kuncitshiswe kakhulu, kwaye ukufana kwazo kuphezulu ngokumangalisayo xa kuthelekiswa nezinye iintlobo zeebhloko zobunzima. Babonelela ngesiseko esithembeke ngakumbi sokulinganisa abavavanyi bobunzima, okwenza abavavanyi bobulukhuni ukuba bafezekise ukuchaneka okuphezulu kunye nokuzinza kwimilinganiselo yabo. Nokuba kukwimveliso yemizi-mveliso, kulawulo lomgangatho kwiilabhoratri, okanye kumacandelo ophando lwezenzululwazi, iibhloko zobunzima boDidi A zidlala indima ebaluleke kakhulu nebalulekileyo, ukunceda iingcali ukuba zifumane idatha yomlinganiselo ochanekileyo nothembekileyo.
Ngokukhetha iibhloko zobunzima beKlasi A, abathengi banokuba nentembelo epheleleyo ekulinganisweni kwabavavanyi bobulukhuni babo, ukuqinisekisa ukuba iziphumo zabo zokuvavanya ubulukhuni zichanekile kwaye zihambelana, kwaye ngaloo ndlela zibonelela ngenkxaso eqinile yokulawula umgangatho kunye nokuphuhliswa kwemveliso yeemveliso zabo.
