Figure 7.2 Exploded Ultrasonic Stack Assembly
7. With two spanner wrenches carefully separate the Booster from the Converter. Check and clean
the mating surfaces of these components with an oilstone or 600-grit paper as shown below.
Place 600 grit emery on a hard, flat surface. Place component on emery with the mating side you
wish to clean face down.
Do not press down. Using only the weight of the converter, booster, or horn as downward
pressure, drag the component across the emery in a single, straight, long stroke (Figure 7.3
).
Figure 7.3 Cleaning object mating surface direction
Turn the component 90 degrees and repeat step 2. Repeat this procedure until all mating
surfaces are clean.
8. Clean and then polish away any roughness on the Diaphragm Spring.
9. Assemble the stack per the steps in the next section.
