Vibratory Finishing Compound

We stock most common and many uncommon vibratory compounds, soaps, detergents and inhibitors.  Having a problem with your current process?  A simple compound change may be the best way to go.  Let us know how we can help!

Vibratory Finishing Media

Vibratory finishing requires the right mix of chemistry and media to achieve results.  We’re happy to work with you and our partners to find the right solution for your process.

Ceramic media uses an abrasive (aluminum oxide or silicon carbide most commonly) blended with clay and formed into a specific size/shape to work with your process.  Ceramic medias are the most aggressive medias and can provide all types of surface finishing including deflashing/deburring , radiusing, Ra surface improvement, edge breaking and super-polishing.

  • 22-degree-angle-trianglesProvides uniform and effective finishing action
  • Retains basic shape throughout usage
  • Most effective on flat surfaces where they provide a maximum amount of surface contact
  • Angled sides provide better corner penetration
  • Provides a sharper angle to better penetrate remote areas
  • Elongated shape gives better flowing action over parts
  • straight-cut-trianglesProvides maximum surface contact on flat surfaces
  • Straight-sided shape gives a blocky action that helps maximize cutting action
  • tri-cylsNew, versatile shape for a wide variety of surfaces
