Instruction Manual
After clamping the sample in the specimen holder, the holder is
placed in the specimen holder head and fixed there. To move the
specimen holder and the sample, the POSITION keys
used. The display shows the position in either X- or Y- direction.
Every time the power is switched on while the cover is closed,
Accutom-50 checks its own reference position. The sample holder
head will be moved back as far as possible, to the reference position
(X=0.000 Y=0.0), and thereafter it will return to the position where it
was before the power was switched on.
The absolute position shows the total distance the specimen holder
has travelled from the reference position.
The relative position equals that of the absolute position until it is set
to zero at a desired point. By setting it to zero, calculation of the
sample movement close to the cut-off wheel or cup wheel is made
easier. The screen value always relates to the distance the specimen
holder has travelled since being set to zero.
The relative zero position is the point where the relative position in
either the X- or Y- position was set to zero. Having completed the
cutting process, the sample holder automatically returns to this point.
Pressing F3 when in the X-or Y- position screen also returns the
sample to the relative zero position.
A stop position can be set to halt the cutting process at a precise
point. After reaching this point the sample will be retracted and
returned to the relative zero position.
Please make sure when setting the stop position to compensate for
possible wear of the cut-off wheel. This is especially important when
using Al
O
or SiC wheels.
