Nka kimwe mu bice byingenzi bya moteri, crankshaft ifite ibikorwa byahujwe no guhinduranya kugoreka no guhinduranya imitwaro ya torsional mugihe cyo kugenda. By'umwihariko, inzibacyuho yuzuye hagati yikinyamakuru na crank ifite impungenge zikomeye zisimburana, kandi imyanya yuzuye ya crankshaft akenshi itera igikonjo kumeneka kubera guhangayikishwa cyane. Kubwibyo, muburyo bwo gushushanya no gukora, birakenewe gushimangira imyanya yuzuye kugirango tunoze imikorere rusange ya crankshaft. Gukomera kwa Crankshaft mubisanzwe bifata gukomera kwa induction, kuvura nitriding, kurasa kurasa, kuzunguruka no gukubita laser.

Kurasa kurasa bikoreshwa mugukuraho igipimo cya oxyde, ingese, umucanga na firime ishaje irangi kubicuruzwa biciriritse binini kandi binini hamwe na casting bifite umubyimba utari munsi ya 2mm cyangwa bidasaba ibipimo nyabyo hamwe na kontour. Nuburyo bwo gukora isuku mbere yo gutwikira hejuru. Kurasa kurasa nabyo byitwa kurasa, bumwe muburyo bwiza bwo kugabanya umunaniro wibice no kongera ubuzima.

Kurasa kurasa bigabanijwe kurasa no guturika umucanga. Ukoresheje ibisasu biturika kugirango bivurwe hejuru, imbaraga zabyo ni nini, kandi ingaruka zo gukora isuku ziragaragara. Nyamara, kuvura ibisahani bito byoroheje ukoresheje kurasa birashobora guhindura byoroshye akazi, kandi isasu ryicyuma rikubita hejuru yakazi (haba kurasa cyangwa guturika) kugirango uhindure substrate yicyuma. Kubera ko Fe3O4 na Fe2O3 bidafite plastike, barashishuye nyuma yo kumeneka, kandi firime yamavuta ni Ibikoresho fatizo bihinduka icyarimwe, bityo guturika no kurasa ntibishobora gukuraho burundu amavuta yibice byakazi hamwe namavuta. Muburyo busanzwe bwo kuvura kubutaka bwibikorwa, ingaruka nziza yo gukora isuku ni umusenyi.
