4: INSTALLATION
We do not recommend setting the backlash greater than 90
arc-seconds (1.5 arc-minutes). It won't improve the life of the
mechanism, and could result in chatter during machine
operations.
Mount the Rotary Table
1. Prevent rust from forming on the machine table from
trapped water-based coolants: put a thin film of oil (WD-
40® or similar) on the surfaces.
2. Depending on your rotary table, do one of the following:
l
6 in. Rotary Table or 8 in. Rotary Table Put the
rotary table on the left side of the machine table.
l
6 in. Super Spacer Rotary Table, 8 in. Super
Spacer Rotary Table, 6 in. Tilting Rotary Table,
or 8 in. Tilting Rotary Table Put the rotary table on
the right side of the machine table.
3. Loosely attach the rotary table toe clamps to the
machine table.
Note: The components are left loose so that
you can adjust the rotary table.
4. Attach a magnetic dial indicator to the spindle head of
the machine.
5. Put the dial indicator on the rotary table so that it will
measure across the platter of the rotary table.
6. Jog the machine from side-to-side in the Y direction to
indicate across the platter.
7. Use a dead blow hammer to tap the rotary table and
adjust its position and reduce any misalignment
determined in Step 6.
8. Completely tighten the rotary table toe clamps to secure
the rotary table to the machine table.
