2-11 ADAPTERS FOR SPECIMEN CLAMPING
2-11-1 ADAPTER, NON-ORIENTING
This adapter replaces the specimen holder and
serves for the non-orienting fastening of the
specimen clamps directly on the feed cylinder.
2-11-2 ADAPTER, ORIENTING,
SPECIMEN ORIENTATION
Using the orienting adapter (fig. 7.4 and 7.5) fasten
the specimen clamps on the feed cylinder. This
allows the specimen to be aligned in relation to the
knife.
Fig. 12
To bring the specimen into the desired position, turn
the eccentric lever (fig. 12.1) to the front. This will
loosen the specimen clamp and a rotation of 360°
on the cylinder axis (Z-axis) is possible. With the
two adjusting screws (fig. 12.2) the specimen
clamp can be oriented by 8° in each direction on
the X-axis and Y-axis. Before starting cutting,
press the eccentric lever (fig. 12.1) upwards to fix
the orientation of the specimen.
NOTE! To avoid undesirable movement while
adjusting the specimen, press the eccentric lever
upwards slightly. This will lightly hold the specimen
clamp.
CAUTION! The spring bolt (fig. 12.3) must
always be tightened to keep the adjusting screws
under constant tension.
2-11-3 CHANGING AND/OR
CLAMPING SPECIMEN
CLAMPS
The available specimen clamps are all clamped or
removed in the same way.
To change a specimen clamp, press the eccentric
lever (fig. 12.1) downwards and pull it sideways in
the direction of the arrow. Slightly unscrew the two
adjusting screws (fig. 12.2) as well as the spring
bolt (fig. 12.3).
Now the specimen clamp can be pulled out and can
be replaced with another specimen clamping
system.
Insert the new specimen clamp into the specimen
holder so that the clamping lever can be put
through the hole of the adapter (fig. 7.5) from the
right side all the way through. Tighten spring bolt
(fig. 12.3). Then align the specimen clamp by
means of the orienting screws (fig. 12.2). Then
press the clamping lever (fig. 12.1) upwards (see
2-11-4, readjusting specimen clamps).
