Mechanical stages with friction adjustment
The drive length and friction for the X- and Y-adjustment can be adjusted individually on the standard
mechanical stage (432035-9002-000) and the mechanical stage 432035-9070-000.
(1) Adjusting the drive length on the stage
drive
The drive length of the X- and Y-drive can be
adjusted by an axial shift of the coaxial knurled
knob (
4
and
1
) within a range of approx.
15 mm.
(2) Adjusting the frictional torque of the
coaxial knurled knobs
for the
X-/Y-adjustment of the mechanical stage
The frictional torque of the coaxial knurled knobs is
factory-preset to a medium level which can be
changed as follows if necessary:
a) X-drive
•
Slide the coaxial knurled knob for the
X-adjustment (
4
) all the way down.
•
Take the enclosed adjustment pin (
5
)
out of the coaxial knurled knob for the
Y-adjustment (
1
) and stick it into one
of the holes on the lower hole nut (
3
).
•
Hold the coaxial knurled knob for the X-adjustment (
4
) and turn the hole nut with the
adjustment pin clockwise (lower frictional torque:
–
) or counterclockwise (higher frictional torque:
+
)
until you reach the desired level of friction (see
•
The adjustment should not be more than
one
rotation.
b) Y-drive
•
Slide the coaxial knurled knob for the Y-adjustment (
1
) all the way up.
•
Stick the enclosed adjustment pin (
5
) into the hole on the upper hole nut (
2
).
•
Hold the coaxial knurled knob for the Y-adjustment (
1
) and turn the hole nut with the
adjustment pin clockwise (lower frictional torque:
–
) or counterclockwise (higher frictional torque:
+
)
until you reach the desired level of friction.
•
The adjustment should not be more than
one
rotation.
•
Replace the adjustment pin in the coaxial knurled knob for the Y-adjustment (
1
).
