What Materials Are Best for Vibratory Finishing?
  • Opening Intro -

    Whenever talking about the process of finishing machined parts, it’s essential to know the specifics behind what that means.

    Different levels of vibratory finishing exist for different parts.


The media that you use to machine them determine their finishes. These are the materials that are best for vibratory finishing and why people use them.

Some media establish size and shape, while others will give you different finishes. You may choose them depending on your desired result.

The Size of Media for Finishing

Your media’s sizes will determine the coarseness or smoothness of the surface you have when you finish a machined product. In other words, if you use a smaller-sized medium, you will obtain a smooth surface.

These media will take what is already relatively smooth, or slightly course, and give it a soft edge or facing.

The larger media will give different results. So, with these, you’ll do more grinding. You might want to cut away at the sharp edges and really grind the shapes down to a more uniform finish.

The Types of Media for Shaping

Generally, regular stones and river stones are media that people use for machined pieces that they need to smooth out and finish. People also use plastics and ceramics, but these generally give more polish to the surface.

Due to the nature of these media, they will buffer more than cut. That’s why professionals use them for polishing.

So, your choice all depends on your products and what you’re trying to accomplish. These media types will determine whether your pieces are smooth and shiny or rough.

The Shapes of Media for Deburring

When choosing vibratory finishing media, you’ll ultimately get smoothed edges and fine finishes if you go with rounded or cylindrical shapes. If your media is coarser and more angled, you’ll end up with smoother internal parts that aren’t easy to achieve, along with finished exteriors.

Examples of these media are those that are triangular in their patterns or geometric in shape. Having smooth interiors is generally a product of manufacturing. Ultimately, the results depend on the parts that you machine.

The effect you need in their finishing can also influence them.

Vibratory machining takes on a certain complexity in terms of how you finish products and use media.

These conditions create the type of result that you aim for in your product. Whether your goal is to have smooth and rounded pieces or polished parts with clean edges and insides, you can know with certainty that the media matters.
