When selecting a media for your vibratory finishing process, you must understand that it will determine the surface quality of the completed part. Larger media, for example, help impinge or impact the parts, which helps with deburring. Smaller media, on the other hand, will cushion the parts more which are ideal for smoothing processes. Then with abrasive, the more aggressive is good for deburring, and with less aggressive is ideal for smoothing, pre-plate, or prepping for polished finishes. As a critical element in the vibratory finishing process, it’s important to understand the nuances involved with media selection. In this post, we’re going to look at the function of media, how it works and what you should expect.
