A high impact speed can also be achieved by high-speed workpiece
rotation inside a tank of abrasives in the bubbling regime.
This technique is extremely useful for axisymmetric or nearly
axisymmetric components. When rotated, the peripheral speed of axisymmetric or nearly axisymmetric workpieces is almost constant.
Thus, the speed of impacts between the workpiece surface
and the fluidized abrasives is the same everywhere, yielding a highquality
finish for the end products.
