That’s not how time machines work. The machine and you both get lifted out of time and moved to another time. In order for the machine itself to disappeared, it would have to be a machine that flings you through time rather than moving through it with you.

No, according to this concept my time travel would probably stop at the moment before I built my machine because I'd have nothing to travel with anymore. No?
