Guhisha ni kashe yo gukoresha kashe yo gutandukanya impapuro nizindi.Guhinyura bivuga ahanini gupfunyika no gukubita.Gukubita cyangwa gutunganya igice gikubita ishusho yifuzwa uhereye kumpapuro kuruhande rwafunzwe byitwa ubusa, naho umwobo utera ishusho wifuza uhereye mugice cyibikorwa byitwa gukubita.
Kwirengagiza nimwe mubikorwa byibanze muburyo bwo gutera kashe.Ntishobora guhita ikubita ibice byarangiye gusa, ahubwo inategura ibisobanuro kubindi bikorwa nko kunama, gushushanya byimbitse no gukora, bityo ikoreshwa cyane mugutunganya kashe.
Guhisha birashobora kugabanywamo ibyiciro bibiri: gusiba bisanzwe no guhanagura neza.Ibisanzwe bisanzwe byerekana gutandukanya impapuro muburyo bwo gukata hagati ya convex na conve bipfa;gupfunyika neza kumenya gutandukanya impapuro muburyo bwa disformasique.
Inzira yo guhindura ibintu igabanijwemo ibice bitatu bikurikira: 1. Icyiciro cyo guhindura ibintu;Icyiciro cyo guhindura plastike;3. Icyiciro cyo gutandukanya kuvunika.
Ubwiza bwigice cyerekeranye no kwambukiranya ibice, imiterere yukuri hamwe nikosa ryimiterere yikigice.Igice cyigice kigomba kuba gihagaritse kandi cyoroshye gishoboka hamwe na burr nto;ibipimo bifatika bigomba kwemezwa kuba murwego rwo kwihanganira ibishushanyo;imiterere yigice cyambaye ubusa igomba kuba yujuje ibisabwa mugushushanya, kandi ubuso bugomba kuba buhagaritse bishoboka.
Hariho ibintu byinshi bigira ingaruka kumiterere yibice byambaye ubusa, cyane cyane birimo ibintu bifatika, ingano yuburinganire nuburinganire, ubukana bwuruhande, imiterere yububiko, imiterere, neza neza, nibindi.
Igice cyigice kigaragara cyerekana ibice bine biranga, aribyo gusinzira, hejuru neza, hejuru ya burr.Imyitozo yerekanye ko mugihe inkombe ya punch itagaragara, hazagaragara burrs kumurongo wo hejuru wigice;mugihe inkombe yumugore ipfuye idahwitse, hazagaragara burrs kumpera yo hepfo yumwobo wigice.
Ikigereranyo cyukuri cyigice cyerekanwe cyerekana itandukaniro riri hagati yubunini nyabwo bwigice cyuzuye nubunini bwibanze.Gutoya itandukaniro, nukuri nukuri.Hariho ibintu bibiri by'ingenzi bigira ingaruka ku bipimo bifatika: 1. Imiterere n'ubuhanga bwo gukubita bipfa;2. Gutandukana igice cyambaye ubusa ugereranije nubunini bwa punch cyangwa gupfa nyuma yo gukubita birangiye.
Imiterere yikosa ryibice byerekana ubusembwa nko kurigata, kugoreka, no guhindura ibintu, kandi ibintu bigira ingaruka biragoye.Ubukungu bushobora kugerwaho nibice rusange byerekana ibyuma ni IT11 ~ IT14, kandi hejuru irashobora kugera kuri IT8 ~ IT10 gusa.
