Iintsimbi ezisetyenziswa ngokuqhelekileyo ukwenza izixhobo zoomatshini bokwakha ziyacinywa kunye nentsimbi epholileyo, intsimbi eqinile, i-carburized and hardened steel and nitrided steel. Amandla egiya yentsimbi etyhidiweyo asezantsi kancinane kuneyeyentsimbi eyenziweyo, kwaye ahlala esetyenziselwa iigiya ezinkulu, intsimbi engwevu ineempawu ezimbi zoomatshini kwaye inokusetyenziselwa ukuhanjiswa kwegiya evulekileyo yomthwalo okhanyayo, intsimbi edityanisiweyo inokuthi ngokuyinxenye. endaweni yentsimbi ukwenza izixhobo.
Kwixesha elizayo, iigiya zoomatshini bokwakha ziyakhula kwicala lomthwalo onzima, isantya esiphezulu, ukuchaneka okuphezulu kunye nokusebenza kakuhle okugqwesileyo, kwaye zizame ukuba mncinci ngobungakanani, ukukhanya ngobunzima, ubomi obude kunye nokuthembeka kwezoqoqosho.
