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, such as; electron-backscatter diffraction (EBSD) applications, AFM (atomic force microscope), SEM (scanning electron microscopy) analysis and Nano indentation or micro- hardness testing. 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, surface polishing on soft and ductile materials such as Titanium, Aluminium, pure Copper and Copper alloys, Aluminium alloys, steel and Nickel-based alloys .
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.
Features
- Low power consumption and noise design with piezoelectric vibratory plate, light weight but stable in operation
- Easily replacement design on disc, convenient to change and clean
- 7" LCD touch screen
- Save up to 20 customized programs
- Automatically adjust frequency setting
- 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.
