7. In the spindle (collet shaft), you are likely to see 3 lines of
debris that need to be cleaned. These are from the slits in
the collet. If they are not cleaned, the collet will not seat
properly and will result in “walking tools”.
NOTE
The lines are not necessarily going to be positioned as
seen in this example. There will be three equidistant lines.
The one on the top cannot be seen from the angle shown.
8. Use the larger bronze wire brush in the collet shaft.
NOTE
Be sure to use a straight in and out motion and do NOT
use a circular motion.
NOTE
The air must be blowing during this step.
9. Use a dental mirror to inspect the spindle or rotate it using
the wrench to ensure all the debris has been removed.
10.Use a DRY paper towel to wipe the inside of the collet
shaft.
To keep your milling unit running smoothly it is very
important to clean the collets and spindles as dirt will
cause the tools to “walk” (not be seated properly) which
coud brake the tools cause broken tools.
These images show the difference before and after five-
minute cleaning.
Make sure to clean the tapered surface inside the shaft
and the front face. The tapered surface is critical.
Clean both outside and inside of collets. Dirt on the
outside can also cause the tools to “walk” if the collet
cannot clamp properly.
