【Abstract】 When we take the pre_cut method in abrading the each end surface of gear,which is cementited and queched,we avoide it cracking because of forming the high rigidity after being cementited and quenched.Through analysing it and finding out the reason,we draw a conclusion.We found it good way to pre_cut the each end surface of gear.更多还原
