Iigiya ze-bevel ezithe tye luhlobo lwecandelo lomatshini elihlala lisetyenziswa kwizixhobo zombane ukuhambisa amandla kunye nokunyakaza phakathi kwee-shafts intersecting kwi-angle ye-90-degree.Ezi ngongoma ziphambili ndingathanda ukwabelana nawe ngazo: Uyilo, umsebenzi, iMathiriyeli, uVeliso, uLondolozo, usetyenziso, izinto eziluncedo kunye nezingeloncedo.Ukuba ukhangela ulwazi oluthile kwiNjaniukuyila, ukukhetha, okanye ukugcina iigiya ze-bevel ezithe ngqo zezixhobo zombane, okanye ukuba unesicelo esithile engqondweni, zive ukhululekile ukunika iinkcukacha ezininzi ukuze ndikuncede ngokubhekele phaya.
