Ni ubuhe burebure buri hagati yumunyururu wa 08B muri milimetero?

08B urunigi bivuga urunigi rw'ingingo 4.Uru ni urunigi rusanzwe rwiburayi rufite ikibanza cya 12.7mm.Itandukaniro kuva muri Amerika isanzwe 40 (ikibuga ni kimwe na 12.7mm) kiri mubugari bwigice cyimbere na diameter yo hanze ya roller.Kubera ko diameter yo hanze ya roller itandukanye, byombi bikoreshwa Amasoko nayo afite itandukaniro mubunini.1. Ukurikije imiterere shingiro yuruhererekane, ni ukuvuga, ukurikije imiterere yibigize, ibice nibice bihuza urunigi, ingano yubunini hagati yibice, nibindi, urutonde rwibicuruzwa byurunigi bigabanijwe.Hariho ubwoko bwinshi bwiminyururu, ariko ibyingenzi byibanze nibyo bikurikira gusa, naho ibindi byose ni deformations zubu bwoko.2. Birashobora kugaragara uhereye kumurongo wavuzwe haruguru ko iminyururu myinshi igizwe nisahani, iminyururu, ibihuru nibindi bice.Ubundi bwoko bw'iminyururu bufite impinduka zitandukanye kuri plaque y'urunigi ukurikije ibikenewe bitandukanye.Bimwe bifite ibikoresho bisakara ku isahani yumunyururu, bimwe bifite ibyuma bifata umurongo ku cyapa cy’urunigi, ndetse bimwe bifite ibyuma bizunguruka ku isahani y’urunigi, n'ibindi. Ibi ni impinduka zo gukoresha mu bikorwa bitandukanye.
