Adjusting Indexing

Adjusting Handwheel
Scale
The degree scale is marked on the edge of the
rotary table in 1° increments (see
Figure 9). The
zero point can be synchronized with the handwheel
to start the table indexing at 0° by using the index
marker as a starting point.
The index marker position for the rotary table can
be adjusted /-2.5° by loosening the thumb-
screw and moving the marker.
The rotary table scale collar is marked in whole
degrees and has a resolution of 1 arc second (
1
⁄
60
of 1°). For every full rotation of the handwheel, the
indexing scale on the rotary table moves 4°.
The handwheel scale (see
Figure 7) can be
repositioned without rotating the handwheel. This
helps when aligning all of the zeroes at the
beginning of a job.
