Table Travel
(X-Axis & Y-Axis)
Using the handwheels, the milling table can be
moved in and out (Y-axis), and left and right
(X-axis). The handwheels are fitted with a gradu-
ated dial shown in Figure
23 that reads in incre-
ments of 0.001" where one complete rotation
equals
1
⁄
8
" of table travel. The Y-axis handwheel
can be disengaged from the leadscrew, so it can
safely freewheel if a power feed is in installed and
in use. Both the X and Y leadscrews are 8 TPI
and 20mm in diameter.
X-Axis
Fastened to the front of the table is a 24" inch long
scale (see
Figure 24) that is broken down in incre-
ments of
1
⁄
8
". This inch scale is used for general
workpiece positioning, and the graduated dial on
the handwheel is for precise positioning.
For milling operations where the table is moved
in or out in the Y-axis, left and right X-axis move-
ment can be prevented by using the table lock
levers located on the front of the table shown in
Figure 25.
The table also is equipped with adjustable table
stops for when X-axis travel must be kept within
range.
Y-Axis
For milling operations where the table is moved
left or right in the X-axis, in and out Y-axis move-
ment can be prevented by using the table lock
levers located under the right-side of the table
shown in
Figure 25.
