Ibice byose byavuwe n'ubushyuhe bigomba gupimwa ubukana hakurikijwe ibipimo bya tekiniki ku bishushanyo n'ibisabwa mu nyandiko z'uburyo ibintu bikorwamo. Igipimo cy'ubukana kigomba gupimwa hakoreshejwe ibice bisanzwe by'ubukana mbere yo gupimwa, kandi ibizamini by'ubukana bishobora gukorwa gusa nyuma yo gupimwa.
Mbere yo gusuzuma ubukana bw'ibice, ubuso bw'igerageza bw'ibice bugomba gusukurwa neza kugira ngo hakurweho burundu ingano, imiterere yakuwemo karubone, uduce twakuwemo karubone n'ibindi bintu bihumanya. Nta bimenyetso bigaragara by'igikoresho cyo gukora bigomba kuguma ku buso bw'igerageza. Ibice bigomba kugeragezwa ku bushyuhe bw'icyumba nk'uko bisanzwe. Niba ubushyuhe bw'ibikoresho burenze gato ubushyuhe bw'ikirere, igeragezwa ntirigomba gukomeza kugeza igihe igikoresho gishobora gufatwa neza n'intoki.
Ahantu ho gupima ubukana hagomba gushyirwaho nk'uko byasobanuwe mu nyandiko z'ibikorwa. Iyo nta ngingo zisobanutse neza zihari, ahantu ho gupima hagomba kugenwa n'abahanga mu gutunganya ibintu n'abagenzuzi.
Uburyo bwo guhitamo icyuma gipima ubukana gikwiye ku bice bivurwa n'ubushyuhe
1. Ibipimo by'ubukana bwa Brinell bikoreshwa ku bice bisanzwe bisanzwe, bipfunyitse, bizimye kandi bikonjeshwa. Ibikoresho by'ubu bwoko bifite ubukana buke muri rusange, ubushobozi bworoshye bwo gukora neza no kuba imiterere y'imbere isa. Indabyo nini ya karubide ikozwe muri sima y'ibipimo bya Brinell ikora agace kanini k'indabyo gafite imiterere myinshi ya metallographic. Impuzandengo y'ubukana bwabonetse irahamye kandi ishobora kugaragaza imiterere rusange y'ibikoresho.
2. Ibipimo by'ubukana bwa Brinell byo mu bwoko bwa Nyundo bishobora gukoreshwa ku bikoresho binini bidashobora gushyirwa ku bikoresho bipima intebe, bigatuma igenzura ryihuse ry'aho hantu rikorerwa hatabayeho gukata ingero.
3.Imashini zipima ubukana bwa Rockwell zikoreshwa ku bice byazimye. Imashini nk'izo zipima ubukana bwa Rockwell zifite ubukana bwinshi n'ubukana bwinshi. Imashini ya Rockwell diamond cone irashobora kwihanganira imbaraga nyinshi zo gupima no gupima byoroshye urwego rwo hejuru rw'ubukana. Ifite agace gato k'ubukana ntikangiza ubuso burangiye neza. Ifite isuzuma ryihuse n'ingero zitaziguye, ikwiriye igenzura ryinshi ry'ibicuruzwa byarangiye birimo imigozi, imashini n'ibikoresho. Ifite imeza yo gukora ya V-type, ishobora gufata neza imashini zikora ku migozi.
4.Ibipimo by'ubukana bwa Vickers bigomba gukoreshwa ku bice bya kaburimbo n'ibikoresho bifite ibice bito bikomeye. Ibipimo by'ubukana bwa kaburimbo n'ibikoresho bifite nitride bifite gusa urwego rworoshye rukomeye rufite substrate yoroshye munsi. Ibipimo bya Vickers bishyigikira imbaraga nto zo gupima kandi bigatanga uduce duto cyane dukora ku buso bukomeye gusa tudaciye mu substrate. Ibi bituma hapimwa neza ubukana nyabwo bw'ubukana bw'ubuso.
Ibi byavuzwe haruguru ni amabwiriza rusange gusa yo guhitamo ibikoresho bipima ubukana. Imiterere nyayo y'ibizamini iragoye, kandi guhitamo ibikoresho bigenwa n'ingano y'ibikoresho, ubugari bw'urwego rukomeye, n'uko imikorere yabyo ihagaze. Amahitamo ya nyuma azagenwa hashingiwe ku miterere nyayo y'ibikoresho. Niba uhuye n'ingorane mu guhitamo icyitegererezo, hamagaraLaizhou LaihuaDutanga ibisubizo by'umwuga ku bikoresho byo gupima ubukana bw'umubiri.
