Vibratory Polisher for Metallography & Petrography

The Vibrapol is an automatic vibratory polisher designed to prepare high quality polished surfaces on a wide variety of materials, especially for electron-backscatter diffraction (EBSD) applications. The high frequency vibration in horizontal motion produces a very effective polishing action to remove minor deformation remaining after mechanical preparation and reveal the stress-free surface. Ideal for EBSD specimens preparation.

The Vibrapol is equipped with a variable frequency and voltage controller, this allows the operator to optimise the frequency and voltage independently depending upon specimen size and weight. The Vibrapol has a programmable timer for better control of the polishing process.


  • Frequency and voltage controls. By adjusting the vibrating frequency, different size specimens can be polished. By changing the applied voltage, the speed of the polishing action can be easily controlled
  • Timer control
  • Capable of handling small or large specimens
  • Multiple sized holders (1" - 2" diameter, other sizes can be customised)
  • Robust and durable design
  • Easy to use and service
  • Ideal for all materials

Vibratory Polishing Basics

Vibratory polishing is a specialised polishing technique for minimising specimen preparation damage. It is a slow polishing process which can take several minutes to hours. Vibratory polishing is a unique mechanical polishing technique which still uses the standard polishing abrasives. Vibratory polishing uses a spring and motor to create the vibration. Essentially, the sample is vibrating up and down; however, by angling the spring mechanism, the specimen will rotate around the polishing bowl. Vibratory polishing is a very low deformation polishing technique; however, polishing action is usually very slow and it is not uncommon to polish samples for hours with this technique. Figure 1 shows the effect of polishing a low carbon steel with standard polishing techniques compared to vibratory polishing. As can be seen in Figures 2 and 3 under DIC illumination, vibratory polishing is an effective polishing technique for removing surface deformation.
