I have a bicycle with a really cheap suspension fork, which is really annoying me when I ride, but I'm broke at the moment, and I can't afford a new fork for a month or two, so I was wondering, if I can somehow disassemble it, and remove the suspension making it rigid.

Can't tell, it depends on just HOW cheap it is. I've come across two that appeared, best as I can tell, to have been press fit assembled. Try as I might, I couldn't find a non-destructive, reversible way into those.
Then there are the RST elastomer forks, rather cheap, but marginally serviceable. They'd be far better candidates for such a treatment, but rigidifying them would still take some serious tinkering. Removing the sus elements isn't enough, as that would make the fork telescope in and out uncontrollably. You'd need to remove the sus elements AND lock the fork legs together, preferably in a slightly compressed position to avoid upsetting the steering geometry too much.

I might try it, but then I've got a lathe and some pipe stock available. I'd still much prefer to source a rigid fork(new or used) from somewhere, and simply swap the fork out. It'd be more reliable, lighter, and a much simpler job.

I've never done this but you might try putting screw-type hose clamps on the fork tubes right where they go into the sliders to stop the travel.

Cheap & easy.

most X-mart full suspension bikes are press fit, and hopeless. You could always change out the fork.

If you can I would drill a hole in the top of the fork blade. tap it and screw some treaded rod down the hole until it reaches a point you desire.
