Rotary Table

Movement

The T1243 rotary table rotates by turning the
3" handwheel, which is attached to a precision
worm gear engaged with a worm wheel. The ratio
between these gears is 90:1, which means one
complete turn of the handwheel rotates the table
4° (see Figure 5).

Adjusting Indexing

Scale

The rotary table scale collar is marked in whole
degrees and has a resolution of 1 arc second (
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.

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 within +/-2.5° by loosening the thumb­screw and moving the marker.

evenly spaced holes in a round workpiece. Always
ensure your rotary table is properly aligned on
the X-axis of the mill before beginning angular
indexing.

Oil Amount ......................................1 or 2 Squirts

Lubrication Frequency .............. Daily/Before Use

Schedule

For optimum performance from your cross-slide
rotary table, follow this maintenance schedule
and refer to any specific instructions given in this
section.

Daily/Before Use:

• Clean and lubricate the ball oilers.

• Dress the machined surfaces.

• Check/resolve any unsafe condition.

Monthly:

• Clean and lubricate X- and Y-axis
leadscrews.

Cleaning &

Protecting

There are two ball oilers that should be oiled on a
daily basis, or before beginning operation. Refer
to Figure 31 for their locations.

Ball Oiler

Locations

It is essential that the rotary table be cleaned
after every use, and the surfaces oiled with a light
machine oil to prevent corrosion.

DO NOT use compressed air to clean your
rotary table. Chips or debris may become lodged
between the moving parts, reducing the life and
accuracy of the device. Instead, use a stiff-bristled
brush to remove the chips and swarf, then wipe
down the surfaces with a clean shop rag.

Model T1243 (Mfd. Since 02/18)

Figure 31. Location of ball oilers.

Lubricate the ball oilers with a pump-type can that
has a plastic or rubberized cone tip. We do not
recommend using metal needle or lance tips, as
they can push the ball too far into the oiler, break
the spring seat, and lodge the ball in the oil galley.

Clean the ball oiler before lubricating. Push the tip
of the oil can nozzle against the ball oiler to cre­ate a hydraulic seal, then pump the oil can once
or twice. If sludge and contaminants come out,
pump the oil can until the oil runs clear. When
finished, wipe off excess oil.

Adjusting Gibs

The function of the gibs is to remove play in the
table (X-axis) and cross slide (Y-axis) without
causing the slides to bind.

Each gib has (3) cap screws that can be adjusted
(see Figure 36). The outer cap screws on each
gib have (1) hex lock nut. When adjusting, make
your adjustments equally and in small increments,
and test the feel of the table movement while
doing so until it feels right.

5. When finished, use Y-axis handwheel to
move table along full length of travel to
spread lubricant evenly along leadscrew.

Note: Y-axis leadscrew cover will close auto-

matically when cross slide moves over it.

Tools Needed Qty

To adjust gibs:

1. Loosen lock nuts under outer gib screws on

X-axis or Y-axis gib (see Figure 36).

Note: For best performance, adjust only one

gib at a time.

2. Depending on current table movement, slight-

ly loosen or tighten each gib screw in equal
amounts, then move table with handwheels
and test feel. When properly adjusted, gibs
should offer slight resistance without binding.

3. Hold gib screw position with hex wrench, then
tighten lock nut. Repeat on all gib screws.
