Tip: When using the rotary table
to machine several locations or
with a complicated pattern, make a
drawing with measurement details
to help visualize the operation. This
will reduce the risk of making errors
during the operation.
To make five evenly spaced holes:
1. Use the handwheel to rotate the
rotary table to the 0° mark on
the rotation scale, then tighten
both table locks.
2. Drill the first hole.
3. Unlock the table, then turn
the handwheel 18 full turns.
This will rotate the rotary table
to 72°, as displayed on the
rotational scale.
important: Be careful not to pass the
handwheel scale 0° mark on the
last turn. If you go past the 0°
mark, reverse the handwheel
one full turn, then try again.
This will eliminate any backlash
error that occurs when reversing
the handwheel direction.
4. Lock the table in place and drill
the hole.
5. Repeat Steps 3–4 to produce
the third hole at 144°, the fourth
hole at 216°, and the fifth hole
at 288°.

To make two circular slots:
1. Use the handwheel to rotate
the rotary table to the 0° mark
on the rotational scale, then
tighten the table locks.
2. Move the mill table to the left
1.125" along the X-axis so that
the spindle is at the starting
point above the lower end of the
upper slot.
3. Install a 1 ⁄
4
" end mill in the mill
spindle, then make a 0.083"
deep hole (approximately
1 ⁄
3
the
cutter diameter).
Two Circular Slots
In this example, you will cut two 92°
circular slots in a round workpiece,
as illustrated in Figure 13.
