2.6. Operating the Polishing Unit

It is assumed in the following that the mounting instructions under point
5.2.1 have been followed.
2.6.1. Dismantling and Assembling the Specimen Holder
To dismantle the two main parts of the specimen holder turn them a little in
relation to each other. Now, they can easily be dismantled.
One half of the specimen holder (Fig. 7.1) contains a displaceable
diaphragm (Fig. 7.3) This diaphragm can now be pressed out from the rear
side.
When assembling the specimen holder (with specimen) the procedure is:
 The two halves are clicked together (the click is heard). The
displaceable diaphragm must not be inserted.
Without the displaceable diaphragm inserted, the specimen holder is

placed on a table in such a way that the big cut-out where the
diaphragm has to be inserted, turns upward. The platinum strip (Fig.
7.4) will be visible through the cut-out.
 The specimen is now placed in the aperture of the platinum strip over
the diaphragm opening (Fig. 7.6) in the bottom half (Fig. 7.2).
 Then the displaceable diaphragm is pressed down into the cut-out, until
it fits tightly against the specimen.
 Now the specimen holder can be mounted in the polishing cell with the
contact piece facing the pump motor. Remember to press the holder
completely down into the polishing cell (See Fig. 9).
 When the polishing is finished, the holder is removed from the polishing
cell and placed in a beaker with water or water/alcohol mixture. Now
the holder can be opened so that the specimen "falls" out into the
beaker. The holder may also be taken out of the beaker and rinsed with
a washing bottle. In that case, the holder is opened and the specimen
taken out with forceps or the like.
2.6.2. Mounting of Jet Holders
The jet holders are equipped with a long sleeve which fits into a
corresponding groove in the polishing cell. The holders are inserted and
taken out in the longitudinal direction of the polishing cell. The procedure is
as follows:
 Place one jet holder in the polishing chamber and slide the sleeve into
the groove until the holder fits tightly against the back wall of the
chamber.
 Mount the other jet holder similarly at the other side of the chamber.
The cut-outs at the top of the holders provide the necessary space for
the fingers (Fig. 6.1). Do not use force. Slide the jets at a right angle to
the polishing cell aperture.
 Connect the two banana plugs in the corresponding sockets in the
holders, one plug in each holder (Fig. 5.1).
 Place the protective casing over the polishing cell (see Fig. 12).
