Inkqubo yesinyithi somgubo ngoku inokuvelisa iintlobo ezininzi zeegiya: iigiya ze-spur, iigiya ze-helical, iigiya eziphindwe kabini, iipuli zebhanti, iigiya ze-bevel, iigiya zobuso, iigiya ze-bevel ezithe tye, iigiya ze-bevel ezijikelezayo kunye neegiya ze-hypoid.Abasebenzisi bahlala bekhetha i-metallurgy engumgubo ukwenza iigiya ngenxa yeenzuzo zayo ezininzi zetekhnoloji:
•Bonelela ngeprofayili yamazinyo eyinyani kunye neradiyasi yefillet epheleleyo.
• Kulula ukufaka imingxunya yokunciphisa ubunzima, ngaloo ndlela kuncitshiswe ubunzima bamalungu.
• Ngenxa yokuba i-material i-porous, inceda ukuthulisa indlela yokubaleka (ukukhululeka kuya kuthothisa isandi) kwaye kuyenze ikwazi ukuzithambisa (ngokuntywiliselwa kwe-oyile).
•Isixhobo sinokudityaniswa nezinye izinto zoomatshini (ezifana neekam, iiratchets, iilugi zokuqhuba okanye ezinye iigiya) zibe sisiqwenga esinye.
• Kuyenzeka ukwenza igiya eneradiyasi kwikona eyimfama, ngaloo ndlela kupheliswe ukukhululwa kwe-undercut efunekayo ekusikeni iigiya kunye nokubonelela ukomelela kweradiyasi eyongezelelweyo.
• Phantse akukho okanye akukho machining efunekayo, kwaye izinga lokusetyenziswa kwemathiriyeli lisondele kwi-100%.
• Iigiya ezineeshafu ezigxunyekwe ngokudibeneyo zinokuveliswa, mhlawumbi njengeetrani ezimfutshane okanye ngokudibanisa iishafti zentsimbi ezenziwe ngoomatshini kwiigiya ngexesha lenkqubo yokuntywila.
