Saturn V rocket because it needed to travel at 36,000km per hour to escape the Earth's atmosphere.

I go for the New Horizons mission to Pluto, due to flyby Pluto and Charon on July 14th 2015, that was launched on January 19th 2006 and is already closing fast on Jupiter, where it will get a gravity assist at the end of February 2007.
The New Horizons spacecraft was launched directly into an Earth- and solar-escape trajectory. It had an Earth-relative velocity of about 16.21 km/s (36,300 mph) just after its last engine shut down, making it the fastest spacecraft launch ever.
It will pass through the Jupiter system at 21 km/s (47,000 mph), with closest approach to Jupiter occurring at approximately 06:00 UTC February 28, 2007. The flyby will increase New Horizons' speed away from the Sun by nearly 4 km/s (9,000 mph), putting the spacecraft on a faster trajectory to Pluto,
Previous missions to Jupiter have taken a minimum of 2 years but this one is taking a mere 13 months, New Horizons is the first of NASA's New Frontiers category of missions, that are larger and more expensive than Discovery missions. So it is not surprising that it is faster than previous missions you could name.
It is in a different league. The spacecraft took only nine hours to reach the Moon's orbit, compared to the three day trip the Apollo 11 spacecraft needed to reach the Moon in 1969.
Weighing in at 478 kgs, the New Horizons mission even has its own webpage where you can follow its journey and discoveries: http://pluto.jhuapl.edu/

Neither a CYCLOTRON or a SYNCHOTRON actually moves itself, so I'd have to say that the fastest machine ever built would have to be one of the unmanned space ships that have left Earth's gravitational field. Probably one of the ones that used Jupiter or Saturn's gravity to slingshot it into space. I believe that was one of the Voyager missions.

The New Horizons Spacecraft headed for Pluto. it passed the moon in just a few hours where it took the Apollo missions 3 days.

It would actually depend on what you mean by fastest. The computer, for example, is pretty fast. But in distance matters, it is the spacecraft we sent into deep space many years ago. I can't recall its name, but perhaps it is above.

Since you are saying A MACHINE.
Technically, a CYCLOTRON or a SYNCHOTRON would be the answer since they accelerate particulate matter to speed near to that of light itself.
But on their own they donot move.
THEY CAUSE MOVEMENT....thus they fit into your criteria!

partical accelerators can move a partical at .99 times the speed of light.

- not only do they stamp out these little machines really fast,
- they also gain an hour each day they are so fast
