S Vibratory Polisher
5.0 Vibratory Polishing Basics
Vibratory polishing is a specialized polishing technique notable for its low sample
deformation. It utilizes easily available standard polishing abrasives such as those
sold at PACE Technologies, and requires minimal operator skill, reducing damage
from human error.
Vibratory polishing uses a spring and motor to create the vibration, and by angling
the spring mechanism, this causes the specimen to rotate around the polishing
bowl. This results in minimal damage to the sample, but can require up to several
hours of polishing. The advantages can be seen in the below figures. Figure 1 and
2 show the effect of polishing a low

carbon steel with standard polishing techniques
while figure 3 shows the results using vibratory polishing. As you can see, vibratory
polishing is an effective polishing technique for removing surface deformation.
