It depends
There is no single right answer to the question of how 'hands-on' a PhD supervisor should be.
In principle, it should be determined by the nature of the project, your existing skills/expertise, and the extent to which the supervisor's skills/expertise are actually conducive to 'micromanagement' (in my discipline, it is rare for any one supervisor to possess all the specialist knowledge needed to manage every aspect of a PhD project in detail; for that reason, a research student often works under 2 or even 3 supervisors, and he/she is expected to acquire a variety of skills/expertise independently, through a combination of reading, doing, and 'hands-on' guidance/training).
In practice, it is often determined by the personality of the supervisor, his/her other commitments, and his/her past experience. What you need to ascertain is why your supervisor is 'micromanaging' your work. Possible reasons may include:
- the supervisor is imparting a skill/specialism that requires intensive instruction and oversight (you should start by assuming this reason);
- the supervisor, when he/she did his/her PhD, may have lacked support from his/her own supervisor, and is 'overcompensating' by going to the opposite extreme in his/her own approach;
- the supervisor may have a history of PhD students failing to complete projects, and is trying to ensure that you succeed;
- the supervisor may think you lack motivation or capability; or
- the supervisor may be a control freak.
It can be a delicate matter asking about this. You could start by asking your supervisor about how he/she thinks you are progressing. Then, you could ask him/her what he/she expects of you in the next few years, and what you need to do to fulfil those expectations. Ask your supervisor to comment on your weaknesses (everyone has weaknesses), and what you could do to improve. If, after asking about these issues, your supervisor does not bring up the issue of 'independence', you should then raise the point -- you could phrase it something like:
I understand that, to get a PhD, I have to make an independent and substantial contribution to knowledge; obviously, I appreciate that this does not happen overnight, but could you tell me what I need to be doing in the next few years to reach that threshold, as a researcher specialising in [insert name of field/discipline/specialism]?
The www is awash with lots of generic advice about this, some of which may be very useful. But keep in mind that the answer will be unique to the individual and the field in which he/she is specialising. In many arts and humanities disciplines, it is often expected that a PhD student should present at conferences and even publish as a sole presenter/author. In the natural sciences, conversely, multi-authored papers are more common.
