Kubera ingaruka z’ibibazo by’amafaranga, igihugu cyacu kizamura cyane icyifuzo cy’imbere mu gihugu, bigatuma isoko ryimbere ry amenyo yindobo ryagize ingaruka nziza, bituma abakora amenyo menshi yindobo ibyiringiro byisoko ryimbere mu gihugu ni byiza!
Igisubizo: isesengura ryibibazo byindobo yinyo ihura nicyiciro cyubucukuzi, mubyiciro bitandukanye byakazi murwego rwo gucukura imbaraga biratandukanye. Igice cyinyo ubanza guhura nubuso bwibintu, kuberako byihuta, indobo igice cyinyo cyakubiswe kuva gikomeye. Niba umusaruro muke wamenyo yindobo, bizana plastike ihindagurika. Hamwe no kwiyongera k'ubucukuzi bw'amabuye y'agaciro, kugabana amenyo y'indobo bizahinduka. Iyo indobo yo gukata amenyo, ibintu bigenda bibaho, iryinyo ryindobo nibintu bitanga umusaruro munini cyane ni umuvuduko wo gusohora hejuru, bityo amenyo yindobo mumaso kandi bigatanga ubushyamirane bunini hagati yibikoresho. Niba ibikoresho ari urutare rukomeye, beto, nibindi, imbaraga zo guterana zigiye kuba nini. Ibisubizo by'iki gikorwa inshuro nke no hejuru yubuso bwinyo yindobo mumaso yo kwambara no kurira, bityo bikabyara imirongo minini. Ibigize amenyo ya dipper ningaruka nziza muburebure bwubuzima bwa menyo yinyoza, hitamo iryinyo ryindobo, byanze bikunze, igicucu cyiyubashye cyagurishije iryinyo ryinyo yamenyo nanjye nakoresheje, ingaruka nibyiza! Isura nyuma yigitutu ikora biragaragara ko iri hejuru kuruta mbere, mbere yo gukora isura ikomeye cyane, kandi irashobora kumenya imbaraga nziza nimbaraga zo guterana imbaraga nuburyo bukomeye bwo kunanirwa kwinyo yindobo amenyo yo hanze, bigira uruhare runini mugikorwa cyo gutanga umusaruro.
2: Isesengura ryuburyo bubiri kuri buri kimwe mbere na nyuma yisura yakazi, ikizamini gikomeye. Byabonetse kurugero rumwe rukomeye itandukaniro ni rinini cyane, urubanza rwibanze ntiruringaniye. Icyitegererezo cyo gusya, gusya, kurigata, wasanze buri sample kumupaka ugaragara, gusa umurongo ibice bitandukanye. Urebye kuri macroscopique, ibara ryijimye, rizengurutse igice cyo hagati, hamwe nibara ryijimye ryerekana ko ikintu gishobora gushyirwaho casting, hejuru, kizengurutswe ibice nabyo bigomba gushyirwaho ibice. Muri HRS - 150 igeragezwa rya digitale ya rockwell hamwe na MHV - 2000 yerekana imashini ya microhardness ya metero kumurongo kumpande zombi zipimishije, byagaragaje itandukaniro rikomeye (reba imbonerahamwe 1).

Imiterere yubukorikori bwibikoresho byuma biterwa nibintu bigize hamwe nuburyo bwo gutunganya ubushyuhe. Itandukaniro hagati yimiterere isa nubukomezi bw amenyo yindobo nta kuvura ubushyuhe bukoreshwa nyuma yo guta. Ishirahamwe riri inyuma yo kwitegereza naryo ryerekana iyi ngingo.
