The essentials of ultrasonic finishing operations
Š
Basic usage
The basic way to use the tool is to place it on the surface and press down lightly while sliding it. The
figure below shows the direction of ultrasonic vibration and the effective sliding direction pattern. The
ultrasonic vibration greatly reduces the resistance to machining, which is more effective in getting the
tool to bite the surface of the workpiece and the tool rather than the machining pressure.
Do not press down on the tool more than necessary and be careful to ensure that the tool touches the
work surface.
Modify the face of the tool as necessary to get a better bite. It is useful to correct the tool by using a
diamond file/sandpaper to create weak vibrations in the tool.
Use the side of the tool
Use the tool at an angle
Use the end face of the tool
Beware of tool bites.
The best angle is about 30

.
Use it while correcting the tool
surface.

Optimal tip length
When using the tip holder with a tip in between, use it within the range of optimum length as shown in
the table below.
Also, please note that it may not vibrate normally due to a defective (or loose) tip holder or tip
installation.

How to use lapping brass tips
When using the lapping brass tips, select the CLAMP mode and adjust the output to the extent that the
protection circuit (see "9 – 3 Protection circuitry ") is not activated. If the output value is too high, it may
stop due to overload.
