7.7.1 Dressing wheels
Purpose: If wheels are dull, the processing time becomes longer or the accuracy in size and
polish becomes low. Dress wheels periodically.
Jig: Dressing stick for roughing wheel (orange) WA80K, dressing stick for finishing wheel
(white) WA320K, compound kit (40380-1700)
1. Be sure to wear protective glasses during dressing wheels. Spray containing processing
waste may cause eye damage.
2. Be sure to select a dressing stick suited to the wheel type. An improper dressing stick
may damage the wheel, which prevents normal lens processing.

Dressing stick for finishing wheel (white) WA320K
Never dress the roughing wheel for plastic lenses. Doing so may damage the wheel,
which prevents normal lens processing.
3. Apply only the flat surface of the tip of the dressing stick to the wheel, not its corners.
Otherwise, the wheel may be damaged.
4. Hold the dressing stick with both hands. The stick cannot be held securely enough with
one hand, and as a result, its corner may contact and damage the wheel.
5. Lightly apply the dressing stick to the wheel. Otherwise, the wheel may be damaged.
6. Dress the wheel holding the dressing stick with a minimum of 2 or 3 cm protruding.
Filure to do so may hurt your fingers due to the contact with the wheel.
7. When the dressing stick is worn to the length of 4 cm, replace it with a new one. As it is
hard to hold the shortened dressing stick securely, your fingers may be hurt or the wheel
may be damaged.
8. Do not rotate/stop a wheel successively ten times or more. Otherwise, operation may
stop as the function to prevent excessive heating is activated.
1. Soak the dressing stick in water and leave it
for 5 minutes.
2. Turn on the main body and press to
display the MENU screen.
3. Press to move the arrow ( → ) to “Wheel
dressing” and press .
The Wheel dressing screen appears.
