Welcome to the forum! Parrots chew on their cage bars for different reasons. It could be boredom, it could be anxiety (budgies don't do well on their own, they need other budgies), it could be that the cage is too small, it could be that they are missing some kind of mineral (inadequate diet -only seeds?), etc. so, basically, it's NOT OK for the bird to do this and you need to figure out what is making him/her do it (most importantly because you can't trust the cage to have a safe finish, it could have lead and kill your bird from metal poisoning).
