Deburring & Finishing
In Turbo-Abrasive Machining, a broad, low-speed airstream is used to impart motion to powdered or granular material within a chamber. The material, typically small aluminum oxide grains, takes on the properties of and behaves like a fluid. In this example, the fluidized bed partially envelops a rotating workpiece, creating a specific abrasive environment for a certain level of deburring and finishing.

T
urbo-Abrasive Machining (also referred to as TAM or Turbo-Finish) is a mechanical deburring and finishing method originally developed to automate edge finishing procedures on complex rotationally oriented and symmetrical aerospace engine compo- nents. Aerospace parts such as turbine and compressor disks, fan disks and impellers pose serious edge finishing problems. Manual methods used in edge finishing for these parts were costly and time-consuming. What’s more, human intervention, no matter how skillful at this final stage of manufacturing, was bound to introduce some measure of non-uniformity in both effects and stresses in critical areas of certain features on the part.
