Its a process that allows custom turbo manufacturers to more easily make custom turbo configurations. Casting a wheel takes a lot of R&D up front to design the wheel and even more time and money to make the tooling to cast the wheel. For custom turbo manufacturers like FP, Kamak, etc. they often don't have the capital or the production volumes to justify the expense of a cast wheel unique to each of the various turbos they make. Machining the wheel from a solid piece of material is more expensive, but allows the manufacturer to more easily change wheel designs as the market moves and the technology develops. Often, rather than choosing an off-the-shelf cast wheel from one of the major manufacturers like Mitsubishi or Garrett, they can customize the wheel to their unique hybrid turbo.

The videos of the 5 axis CNC's making these wheels is really neat to watch.
