Guide for Process Media


  • Shape: Due to its shape, the abrasive media must reach all contours (especially corners, edges and holes) of the workpiece and should not jam. Angular media shapes tend to have a more aggressive grinding behavior than round shapes.
  • Size: With increasing size and weight of the abrasive the grinding performance increases. The grinding pattern becomes rougher.
  • Material: Plastic and ceramic media are often used, but special media made from steel, wood or glass are also used for specific applications.
  • Quality: The quality of the grinding performance has a significant influence on the grinding process and the grinding pattern. The grinding performance ranges from A (very abrasive) to P (polishing).
  • Separating: In order to enable economical separation, there should be a sufficient difference in size between the workpiece and the abrasive media. With normal separation, the abrasive media is smaller than the workpiece, so it is discharged through a sieve. In special cases, a reverse separation, magnet separation or an individual concept can be used.


  • Type: Liquid additives (compounds) are usually used to support the vibratory finishing process. Powdered additives and pastes are added in individual cases depending on the requirement and goal.
  • Purpose: Compounds support the removal of grinding abrasion from the vibratory finishing container via the liquid that is added during the grinding process. They optimize the vibratory finishing process, increase the abrasiveness, chemically clean and polish the material surface.
  • Selection: In addition to the area of application, selection criteria for compounds include the material to be processed, the desired processing result and the compound properties:
    • Corrosion protection
    • Recyclability (e.g. with centrifuges)
    • Brightening
    • Degreasing and cleaning


  • Defoamer: Can be used in the case of heavy foaming in the circulatory system to reduce foaming.
  • Adhesion prevention: To reduce the attachment (adhesion) of components.
  • Grinding additive: Addition during the machining process to specifically influence the grinding result.

Article Number Key

All abrasive medias are provided with an individual article code in order to clearly identify them.

Quality / Grinding performance

The grinding performance has a significant influence on the grinding process and the grinding pattern. The qualities range from A (very abrasive) to P (polishing). In addition to the quality, the media size also influences the grinding performance.

With quality P, the grinding wheel is made of pure porcelain (Ceramic), which can serve as a carrier for grinding pastes or other additives. The abrasive media itself has no abrasion.

Depending on the media shape and size, several grinding stages are available.
