GIGA-S Vibratory Polisher
2.0 Product Description
2.1 General Description
3
The GIGA-S is a metallographic vibratory polishing unit used for final polishing of
specimens. The GIGA-S utilizes a piezoelectric (PZT) motor set to a specific
customizable frequency and voltage to slowly polish the surface of a placed
specimen. When used in conjunction with PACE polishing slurries, a sub-micron
finish can be achieved on all materials. The GIGA-S accepts both 9 and 12 inch
polishing bowls, which allows specimens with a large variety of shapes and sizes to
be polished with minimal operator attention. Pulse Mode is a new feature to the
GIGA line that reduces the risk of staining samples left in polishing slurries. This
mode also stops certain polishing slurries from conglomerating after a procedure is
completed.

4.3 Locking Mechanism
Insert the locking handle straight into the side port of the GIGA. Once inside, the
handle should be guided into the hex-shaped hole on the bowl locking mechanism.
Rotate the handle about 180 clockwise. The front panel will indicate when the bowl
is engaged in the lock. Remove the handle and place next to the
machine. The handle should not be left in the machine while it is running.
The frequency set at the factory is ideal for compression mounts that have been
mounted in their respective GIGA sample holders. The GIGA-S is fully capable
of handling irregular and heavy objects. If the user wishes to place a large or
irregularly shaped object in the bowl, it is recommended to adjust the frequency
to ensure optimal polishing. If similar parts are polished often, the ability to save
the procedure is available. The desired frequency can be found as follows:
4.4 Finding the Correct Frequency
1. Lock down the GIGA bowl and ensure the Locking Indicator is ON.
2. Fill the GIGA bowl with the intended polishing medium.
3. Place the sample(s) inside the bowl.
4. If the user plans to program settings for one of the buttons, follow the
directions in section 4.5 Programming a Button.
5. Start the machine with the Run/Stop button.
6. Press the frequency button and adjust up or down until the sample starts to
move.
7. Continue adjusting the frequency up or down in small increments until the
sample is moving at the desired rate in a continuous smooth circle.
8. Press frequency again to save the parameter.

4.5 Programming a Button
1. Press and hold the button that you would like to set parameters to: P1, P2, or P3.
2. Set the timer to desired time.
3. Change the speed to desired speed setting.
4. Toggle Pulse mode on or off.
5. Press button again to save.
4.6 Finding the Correct Speed
Once the optimal frequency is found, the speed setting needs to be set. Speed is
simply the amplitude of the vibration. Increase the speed to make the specimen(s)
rotate faster. If they are moving smoothly across the surface of the bowl, the speed
setting is ideal. Once the samples start to jiggle or lift noticeably from the bowl, the
speed is too high and will not be as effective at polishing.

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.

6.0 Maintenance
6.1 Introduction
The GIGA-S polisher is a low maintenance machine. In order to maintain proper
performance, it is advised to properly clean the polishing bowl after every use.
Some abrasive slurries will conglomerate and introduce contamination to future
polishing steps if not properly cleaned. The hinged hood should be wiped down
with a damp cloth when small contaminants can be seen. If a large amount of
sloshing has occurred, the hood should be removed and thoroughly cleaned to
reduce the risk of contamination.
6.2 Instructions
Take a damp cloth and lightly scrub the surface of the cover and hood. Do not
use chemicals to clean.
To remove the hood for cleaning, loosen the four thumb screws on the back of
the machine (shown below). Clean the hood with soapy water. Place the hood
back onto the hinges and tighten the thumb screws to secure the hood back in
place.
It is recommended to clean the hood after use before slurries or other polishing
mediums have time to dry.
To clean the GIGA-S polishing bowl, simply remove the bowl from the locking
plate and properly dispense of any polishing medium. Remove the polishing cloth
and continue to wash the bowl as needed.
