Kubera ko ari ibikoresho nyamukuru mu gukora amashini mu buryo bubereye, ubushobozi bw’amamashini yo gutoza buvana canecane n’ibiranga ubuhinga bw’ibihimba vyayo nyamukuru. Ivyo bihimba bifatanya ubuhinga bwo gukora ibintu mu buryo bubereye cane n’uburyo bwo kubikora buteye imbere kugira ngo bibe vyiza kandi bihoraho.
Ugukomera cane no guhangana n’ugusambuka ni vyo biranga canecane ibihimba vy’imashini yo gutoza. Nk’akarorero, ibihimba bikorana ata guca ku ruhande n’igikoresho, nk’umutwe wo gukosora n’ibikoresho vyo kuyobora, akenshi bikozwe mu gicupa c’amabuye y’agaciro, mu mabuye y’agaciro, canke bipfutse kugira ngo bishobore guhangana n’ugushikana kw’incuro nyinshi-n’ugucapura kw’inguvu nyinshi-. Ivyo bikoresho ntibikomeye cane gusa (bishika kuri HRC60 no hejuru) ariko kandi vyerekana ubushobozi bwiza cane bwo guhangana n’urushe, bikaba bituma ibihimba vy’umubiri bimara igihe kirekire.
Gucungera neza ukwihangana ni ikindi kintu nyamukuru c’ubuhinga. Ugukora neza kw’ibihimba bigendagenda mu mashini yo gutoza, nk’umurongo w’ivyuma n’ivyuma vy’amazi, mu bisanzwe bishika ku rugero rwa micron- (nk’akarorero, ±0.001mm) kugira ngo haboneke ko hariho ugushikama kw’ibintu bimwe bimwe n’ugushikama kw’ingero mu gihe c’ugutoza. Nk’akarorero, ibikoresho vy’uruzitiro vy’imbere, bifatanijwe n’ibirongozi vy’uburemere bwinshi, biragabanya ukunyiganyiga, bikaba bituma igikoresho gikoreshwa gikomeye cane kiri munsi ya Ra0.1μm. Ugushikama kw’ubushuhe n’ugushikama kw’inguvu na vyo nyene ni ngirakamaro cane. Ubushuhe buva mu gihe c’ugutera ivyatsi burashobora gutuma ibihimba bihinduka bivanye n’ubushuhe. Ku bw’ivyo, ibihimba nyamukuru (nk’igitanda c’imashini) akenshi vyubakwa mu cuma canke mu mabuye y’agaciro kugira ngo bikoreshe ubushobozi bwavyo bwo kwagura ubushuhe buke kugira ngo bigumye bikora neza. Ikindi kandi, ibice bizunguruka vyihuta cane- (nk’inkoni yo gutera) bisaba uburinganire bukomeye bw’inguvu kugira ngo ntihagire amakosa y’ugunyiganyiga aterwa n’inguvu zigenda zihinduka.
Vyongeye, ibihimba vy’imashini zo gusukura vyo muri iki gihe birarushiriza gushiramwo ibintu vy’ubwenge, nk’ibikoresho bifatanya kugira ngo bigenzure ukuntu ibintu vyambaye be n’imiterere y’ibintu bishobora gusubirwamwo ningoga. Ivyo bikoresho vy’ubuhinga biriko biratuma igikorwa co guhingura ibintu bigenda neza cane kandi kikaba gifise ubwenge bwinshi, bikaba bituma kiba ikintu gihambaye mu guhingura ibintu vy’agaciro kanini.
