Mbere yo gushyiraho imashini yandika, izuba riva mu mwobo wateranirijwe gusukurwa neza no gusiga amavuta. Uruhande runini rw'umuzingo rw'ibumoso rugomba kureba hejuru iburyo, naho uruhande runini rw'umuzingo rw'iburyo rugana hasi ibumoso. Isahani yo gukanda igomba gushyirwaho mu mwobo.
1. Urupapuro rupfa guhindurwa ruhindurwa muguhindura uruzitiro rwa eccentric anticlockwise kugirango uruzitiro ruto kandi rugeze kumasaha kugirango rube runini. Impeta nshya ipfa igomba gushyirwaho umuzingo mushya ufite imashini igera kuri 0.2mm hamwe nigihe gisanzwe cyo gukora cya 0.3mm. Guhindura umuzingo upfa icyuho ni ngombwa cyane. Ikinyuranyo ni gito cyane, umuzingo upfa guhuza, kwambara biriyongera, kandi umwobo wamahembe wangiritse no kuzunguruka; Niba gukuraho ari binini cyane, ibisohoka bizagira ingaruka, kandi imashini iroroshye guhagarikwa, cyangwa ntishobora guhindurwa. Ubunararibonye busangiwe na shobuja ushaje nuko iyo impeta ipfuye ihinduwe n'intoki, nibyiza ko uruziga ruhinduka.
2. Ihuza rya axial yumuzingo wimpeta nimpeta ipfa cyane cyane bivuze ko umwanya wa axial wumuzingo wamakuru hamwe nisura ikora yimpeta bipfa kuba bikwiye. Byinshi mubinyamakuru byandika bikora ni 4mm mugari kuruta isura ikora yimpeta ipfa. Ibyiza cyane ni ugukwirakwiza 2mm imbere n'inyuma. Uburyo bwo gupima ni ugupima intera iri hagati yisura yanyuma yimpeta ipfa nisura yanyuma yumuzingo wamakuru hamwe na caliper ya vernier ishobora gupima ubujyakuzimu, hanyuma ukabara niba bifite ishingiro mbere yo kugira ibyo uhindura. Niba impinduka zibaye, mubisanzwe bibaho nyuma yo gusimbuza urufunguzo nyamukuru, cyangwa imizigo idasanzwe hamwe nibikoresho bikoreshwa.
