TURBOFINISH Application: Turbo-charger Rotors

TAM technology has several advantages over other mechanical finishing processes, such as a high flow of free abrasive grain that allows for penetration of abrasive media particles into difficult to access part areas that require edge and surface finish improvement. Another advantage is lower energy consumption, especially in contrast to pressure-blast surface finishing. It also has very simple tooling, processing, and maintenance requirements.

Turbocharger rotors such as these can be deburred in short cycle times of a few minutes

Although these rotors can pose a nesting or impingement problem for mass media finishing methods such as barrel and vibratory finishing, edge finish can be accomplished uniformly with a high-speed spindle finish process in a dry abrasive environment with blasting grains lasting a few minutes

Turbo-finishing—or turbo-abrasive machining—is a loose, abrasive machining method that can deburr and produce edge contour effects very rapidly. The method is especially useful for the final machining and finishing of larger complex rotating components. These types of parts often are not good candidates for other mass media finishing techniques and until now have required very tedious and expensive manual deburring.
The turbo-abrasive machining (TAM) process can automate much of this work, not only reducing labor and costs, but improving the uniformity and consistency of edge and surface effects in…
