Igipimo cy'ubukomere bwa Leeb
Kuri ubu, ikigeragezo cy’ubukana cya Leeb gikoreshwa cyane mu gupima ubukana bw’ibice bicukurwamo. Ikigeragezo cy’ubukana cya Leeb gikoresha ihame ryo gupima ubukana bw’ibice bicukurwamo kandi gikoresha ikoranabuhanga rya mudasobwa kugira ngo gikoreshwe mu buryo buciriritse no mu buryo bw’ikoranabuhanga. Ni ikintu cyoroshye kandi cyoroshye gukoresha, isesengura rirasobanutse neza, kandi ibisubizo by’ibizamini bishobora guhindurwa byoroshye mu gaciro k’ubukana bwa Brinell, bityo kirakirwa cyane.
Imashini nyinshi zo gucukura ziba ari ntoya cyane, zimwe muri zo zipima toni nyinshi, kandi ntizishobora kugeragezwa ku gipimo cy’ubukana. Isuzuma ry’ubukana ry’imashini zo gucukura rikoresha cyane cyane inkoni zo gucukura cyangwa ibice by’igerageza bifatanye n’imashini zo gucukura. Ariko, nta gice cy’igerageza cyangwa igice cy’igerageza gishobora gusimbura burundu igikoresho ubwacyo. Nubwo cyaba ari itanura rimwe ry’icyuma gishongeshejwe, uburyo bwo gucukura n’imiterere yo kuvura ubushyuhe ni bimwe. Kubera itandukaniro rinini mu bunini, igipimo cyo gushyushya, cyane cyane igipimo cyo gukonjesha, kizaba gitandukanye. Biragoye gutuma byombi bikomera kimwe. Kubera iyo mpamvu, abakiriya benshi bita cyane ku bukana bw’igikoresho ubwacyo. Ibi bisaba icyuma gipima ubukana bwo gutwara kugira ngo gipime ubukana bw’imashini zo gucukura. Iki gipimo cy’ubukana cya Leeb gikemura iki kibazo, ariko ni ngombwa kwita ku iherezo ry’icyuma mu gihe cyo gukoresha iki gipimo cy’ubukana cya Leeb. Iki gipimo cy’ubukana cya Leeb gifite ibisabwa ku bukana bw’ubukana bw’icyuma.
Igipimo cy'Uburimbane bwa Brinell
Igipimo cy'ubukana bwa Brinell kigomba gukoreshwa mu gupima ubukana bw'ibice bicukurwa. Ku bicukurwa by'icyuma by'umukara bifite ibinyampeke bito cyane, imiterere y'ikizamini cya 3000kg n'umupira wa 10mm bigomba gukoreshwa uko bishoboka kose. Iyo ingano y'igipimo ari nto, igipimo cy'ubukana cya Rockwell nacyo gishobora gukoreshwa.
Ubusanzwe ibikoresho by'icyuma bicukurwamo ibyuma bifite imiterere idahuye, ibinyampeke binini, kandi birimo karuboni, silikoni n'indi myanda myinshi kurusha icyuma, kandi ubukana buratandukana mu duce duto dutandukanye cyangwa ahantu hatandukanye. Indangururamajwi y'icyuma gipima ubukana cya Brinell ifite ingano nini n'agace kanini k'indangururamajwi, kandi ishobora gupima agaciro mpuzandengo k'ubukana bw'ibikoresho mu rugero runaka. Kubwibyo, icyuma gipima ubukana cya Brinell gifite ubuziranenge bwo gupima no gukwirakwiza guto kw'agaciro k'ubukana. Agaciro k'ubukana gapimwe kagaragaza ubukana nyabwo bw'igikoresho. Kubwibyo, icyuma gipima ubukana cya Brinell gikoreshwa cyane mu nganda z'ubucuzi.
Ubukomere bwa Rockwell
Ibipimo by'ubukana bwa Rockwell nabyo bikunze gukoreshwa mu gupima ubukana bw'icyuma gishongeshejwe. Ku bikoresho bifite ibinyampeke byiza, niba nta buso buhagije bwo gupima ubukana bwa Brinell, ikizamini cy'ubukana bwa Rockwell nacyo gishobora gukorwa. Ku byuma bishongeshejwe bishobora gukoreshwa mu buryo bwa pearlitic, icyuma gishongeshejwe gikonje n'icyuma gishongeshejwe, igipimo cya HRB cyangwa HRC gishobora gukoreshwa. Niba ibikoresho bitangana, hagomba gupimwa ibipimo byinshi kandi hagafatwa agaciro mpuzandengo.
Igipimo cy'Uburimbane bw'Inkombe
Mu bihe bimwe na bimwe, kuri bimwe mu bikoresho bifite imiterere minini, ntibyemewe gukata icyitegererezo, kandi ntibyemewe gupima ibindi bikoresho kugira ngo bipime ubukana. Muri iki gihe, isuzuma ry'ubukana rizahura n'ingorane. Kuri iki kibazo, uburyo busanzwe ni ugupima ubukana hakoreshejwe icyuma gipima ubukana cya Shore ku buso bworoshye nyuma yo kurangiza gukora. Urugero, mu buryo busanzwe bukoreshwa cyane mu nganda zikora ibyuma, hateganywa ko icyuma gipima ubukana cya Shore kigomba gukoreshwa mu gupima ubukana.
