Check of mechanical alignment
1) Place 10mm gauge block on the lens transducer and tighten
the chuck.
2) Switch on the digital dial gauge and hold the SET / ZERO button for two seconds. Now
in the display appears +10.0000 mm and P flashes. Pressing the Set button to set this
value (+10.0000 mm).
3) Operate the left switch (the measuring tips touch the 10mmgauge block). It is important
that the upper measuring tip first touch the gauge block. Then, press the SET button
on the remote controller. The gauge is now calibrated for +10.0000 mm.

4) Should the bottom measuring tip touch the block first, you can use the torx screwdriver
and make a new adjustment of your lower mess point. Loosen the screwfrom the shaft
holder and move the shaft. Then fix the screw again.
5) Set the digital dial gauge to 10.0000 mm and make some measurements again. The
value must be 10.0000 mm.
6) To know how save your repeatability measurement is, you can form the arithmetic
mean value with this formula:
  

7) If you have big deviations, please check the situation/quality of the special measuring
tips. It is important that you use only the Xonox measuring tips, no ruby or similar.
8) To control the mechanical axis, demount both measuring tips and put the measuring
sleeve on the shaft.

9) Now you can check the alignment of the mechanical axis: Lead the upper and lower
shaft together and move the measuring sleeve over the shafts.
10)When the alignment of the axis are correctly, the measuring sleeve can be moved
without chopping.
11)Control the orientation to the chuck: Clamp the measuring sleeve in the chuck and let
the upper and lower shaft glide into the measuring sleeve. For this action, the upper
boom can be held by hand and the lower boom can be operated with the pneumatic
(left) switch. When you see that the lower shaft entering into the measuring sleeve,
lead the upper shaft by hand in the measuring sleeve.
12)When the alignment is centered, both shafts slide into the measuring sleeve. Now you
know that you are measuring centrically in the middle.

13) For a significant measuring value you can use a CaliBall. We make the quality
assurance for the CT’s with a CaliBall Ø 25,400. Tolerance for the measurements are
4 µm.
14)It is absolutely forbidden to set the dial gauge to zero when the measuring tips stay in
contact! In additional it is very important that the alignment of the CT don’t be checked
in this way!
15)Use always the gauge block to set the digital dial gauge to zero!
