Ikizamini cya Leeb
Kugeza ubu, igeragezwa rya Leeb rikoreshwa cyane mugupima ubukana bwa casting.Igeragezwa rya Leeb rikoresha ihame ryo kugerageza imbaraga zikomeye kandi rikoresha ikoranabuhanga rya mudasobwa kugirango menye miniaturizasiya na elegitoronike yipimisha.Nibyoroshye kandi byoroshye gukoresha, gusoma birarenze, kandi ibisubizo byikizamini birashobora guhinduka byoroshye indangagaciro za Brinell, bityo biremewe cyane.
Abakinnyi benshi bakina ni ibiciriritse-binini-binini, bimwe muribi bipima toni nyinshi, kandi ntibishobora kugeragezwa ku ntebe yo hejuru.Ikizamini gisobanutse neza cyabakinnyi bakoresha cyane cyane inkoni yikizamini cyangwa ibizamini byo kwizirika bifatanye.Ariko, ntagahunda yikizamini cyangwa ikizamini gishobora gusimbuza rwose igihangano ubwacyo.Nubwo ari itanura rimwe ryicyuma gishongeshejwe, uburyo bwo gutara hamwe nuburyo bwo kuvura ubushyuhe burasa.Kubera itandukaniro rinini mubunini, igipimo cyo gushyushya, cyane cyane igipimo cyo gukonja, kizaba gitandukanye.Biragoye gutuma byombi bigira ubukana bumwe.Kubera iyo mpamvu, abakiriya benshi bita cyane kandi bizera ubukana bwakazi.Ibi bisaba kwipimisha neza kwipimisha kugirango ugerageze ubukana bwa casting.Igeragezwa rya Leeb rikemura iki kibazo, ariko birakenewe ko witondera kurangiza hejuru yumurimo mugihe cyo gukoresha ikizamini cya Leeb.Ikizamini cya Leeb gikomeye gisabwa kubuso bukabije bwakazi.
Ikizamini cya Brinell
Ikizamini cya Brinell gikwiye gukoreshwa mugupima ubukana bwa casting.Kubyuma byicyuma gifite ibara ryinshi ugereranije, ibipimo byikigereranyo cyingufu za 3000 kg hamwe numupira wa 10mm bigomba gukoreshwa bishoboka.Iyo ubunini bwa casting ari buto, ibizamini bya Rockwell birashobora kandi gukoreshwa.
Ubusanzwe ibyuma biba bifite imiterere itaringaniye, ingano nini, kandi irimo karubone, silikoni nindi myanda myinshi kuruta ibyuma, kandi ubukana buratandukana mubice bito cyangwa ahantu hatandukanye.Indenter yipimisha rya Brinell ifite ubunini bunini nubuso bunini bwerekana, kandi irashobora gupima impuzandengo yimpuzandengo yubukomere bwibintu murwego runaka.Kubwibyo, igeragezwa rya Brinell rifite ibipimo bihanitse kandi bitandukanije agaciro gakomeye.Igipimo cyapimwe agaciro nikigaragaza cyane ubukana nyabwo bwakazi.Kubwibyo, ibizamini bya Brinell bikoreshwa cyane mubikorwa byinganda.
Gukomera kwa Rockwell
Abagerageza gukomera kwa Rockwell nabo bakunze gukoreshwa mugupima ubukana bwa fer.Kubice byakazi bifite ibinyampeke byiza, niba ntahantu hahagije ho kwipimisha Brinell, ikizamini cya Rockwell nacyo gishobora gukorwa.Kuri pearlitis malleable cast fer, ibyuma bikonje bikonje hamwe nicyuma, igipimo cya HRB cyangwa HRC kirashobora gukoreshwa.Niba ibikoresho bitaringaniye, ibyasomwe byinshi bigomba gupimwa kandi impuzandengo igomba gufatwa.
Ikizamini cyo Gukomera
Mubibazo byihariye, kubantu bamwe bafite imiterere nini, ntabwo byemewe guca icyitegererezo, kandi ntibyemewe guteramo ibizamini byinyongera kugirango bipimishe.Muri iki gihe, kugerageza gukomera bizahura ningorane.Kuri iki kibazo, uburyo busanzwe ni ukugerageza ubukana hamwe nogupimisha Shore igerageza hejuru yubutaka nyuma yo gukina birangiye.Kurugero, murwego rusanzwe rukoreshwa cyane munganda zibyuma, hateganijwe ko ibizamini byo gukomera bya Shore bigomba gukoreshwa mugupima ubukana.
