6. Handling procedures for the output shaft
The output shaft on an indexing drive is subject to momentous torque during starting
and stopping. Therefore, the shaft must be torsionally rigid. To maintain positioning
accuracy, the output shaft must have minimal run out. The run out on a standard SANDEX
is within 0.02 mm (.0008 ).
Note
The SANDEX is designed to show accuracy as it stops. When aligning shafts, do so after
repeated indexing and make sure the shaft is in a dwell.
There are different handling methods for various configurations of the final turret. The
following indexing drive handling procedures also apply for roller drives and oscillating
drives.
6.1 Table type output
(1)
Table type output sections have a broader mounting surface than flange type output.
Tables can be mounted easily and accurately.
(2)
To accurately position work stations on the table, enlarge the hole in the center of the
table from 0.1 to 0.2 mm (.004

(3)
The center of output shaft has a fixed flange with a hole in it. This fixed flange is suitable
for directly mounting fixed tables. A hole can be drilled in the mounting base in line with
the center of the output shaft for concealing wiring and plumbing.
