i dont understand..
what is chain punching? if you hit someone once and it wasnt enough then you keep hitting until it is. If that person is fighting back then you hit when you can.
'chain punching' as a concept seems to imply a lack of awareness of your opponent, as if you just hit randomly, even against a punch bag chain punching is bad because it doesnt take into account any movement of the bag, relative strength of any punch vs another, movement of you around target etc.
if you simply mean ' keep hitting really fast' ...
shouldnt that be so obvious as not to require a term 'chain punching'?
