Mounting of specimen and
adjustment of specimen holder
Accutom-2
Instruction Manual
Specimen holder for affixation of specimen (CATPE). The block has a
surface of 40 x 30 mm, suitable for affixation of the specimen with
double adhesive tape, thermoplastic or ordinary glue.
Specimen holder with vacuum holder (CATAP). The vacuum holder has
the dimensions 30 x 50 mm. Well suited for vacuum clamping of plane
specimens, e.g. thin sections on a glass plate. Without vacuum pump.
Specimen holder with parallel vice, small (CATAN). As CATCH.
However, max. dimensions between the screws 16 mm.
Dovetail plate for mounting of user's own specimen holder (CATFU).
Length 60 mm.
The specimen must be clamped/be supported in the specimen holder so
that it moves as little as possible during the cutting. Inconvenient
movements may lead to damaging of the cut-off wheel and the specimen,
and under all circumstances cause a bad cutting quality.
When cutting with the rotating or swivelling cutting stand the specimen
should be placed so that by rotation or swivelling it moves as little as
possible, i.e. it moves on its own axis. Thus the fastest cutting is obtained,
as most of the time the cut-off wheel will be cutting.
The movement of the cutting table is so precise that an asymmetric
clamping of the specimen will not affect the cutting quality, it only gives a
longer cutting time.
When using the stand for fixed specimen holder the specimen should be
placed so that the cut-off wheel cuts through the smallest cross section.
It is advantageous to place the specimen so that as little a variation of the
cross section as possible is obtained.
Notice that the cut-off wheel must be able to cut through the specimen
without the latter touching the flanges. Normally, this will not provide any
problem when using diamond cut-off wheels, as they do not wear.
Depending on the specimen to be cut, the wear can vary with the cut-off
wheels 356CA and 357CA. Therefore, the condition of the cutting should be
checked at regular intervals.
The specimen should protrude at least 6 mm from the specimen holder
which might otherwise come in touch with the flanges.
It is especially important to pay attention to this fact when the
rotating/swivelling stand is used.
