Hagati yumuriro wamashanyarazi garebox ifite uruhare runini muguhindura ingufu za mashini mumashanyarazi. Mubice bitandukanye biri muriyi sanduku, ibikoresho bya bevel naibikoresho bya tekinikeuhagarare nkabashya bashya mugukwirakwiza amashanyarazi.
 Ibikoresho bya Bevel, bizwiho ubushobozi bwo guhindura icyerekezo cyo kuzunguruka, ni ntangarugero mumashanyarazi ya garebox. Igishushanyo cyihariye cyinyo cyemerera uburyo bworoshye bwo kohereza ingufu, kugabanya kunyeganyega n urusaku. Ibi bituma biba byiza mubikorwa aho umwanya ari muto kandi neza ni ngombwa.
ibikoresho bya tekinike, kurundi ruhande, tanga uruvange rwimikorere nimbaraga. Uburyo bwabo bwo kumenyo bwinyo bugabanya guterana no kwambara, byongerera igihe cya garebox. Byongeye kandi, ibyuma bya tekinike birashobora kohereza umuriro mwinshi kandi bigakora ku muvuduko mwinshi ugereranije n’ibikoresho byaciwe neza, bigatuma bahitamo icyifuzo cyo gukora imirimo iremereye mu mashanyarazi.

Udushya twa vuba muri bevel naibikoresho bya tekinikeigishushanyo cyarushijeho kuzamura imikorere yabo. Ibikoresho bigezweho, nkimbaraga nyinshi zivanze hamwe nibihimbano, byashizwemo kugirango bitezimbere kandi birwanya kwambara. Byongeye kandi, tekinoroji yo gukora neza, harimo igishushanyo gifashwa na mudasobwa (CAD) hamwe na mudasobwa igenzurwa numubare (CNC), menya neza ko buri bikoresho byakozwe muburyo bwihariye.

Ibi bishya ntabwo byateje imbere gusa uburyo bwo kohereza amashanyarazi ahubwo byanagabanije ibisabwa byo kubungabunga no gukoresha amafaranga. Muguhindura imyirondoro yinyo no kugabanya ubukana, agasanduku gare gashobora gukora neza bucece kandi neza, kugabanya igihe cyateganijwe no kuzamura imikorere yibiti muri rusange.
Mu gusoza, ibyuma bya beveri hamwe nibikoresho bya tekinike ni ibintu by'ingenzi mu isanduku y’amashanyarazi, bitera udushya mu guhererekanya amashanyarazi. Mugihe ikoranabuhanga rikomeje gutera imbere, turashobora kwitega ko tunonosorwa byinshi mugushushanya ibikoresho no gukora, amaherezo bikagira uruhare mukwizerwa no gukora neza sisitemu yo kubyara amashanyarazi.
