Compound Slide

Similar to the cross slide, the compound slide
features a scale that displays graduations of one
thousandths of an inch (0.002") or 0.05mm.
Unlike the cross slide, the compound slide can
be rotated to a set angle and then it can be
moved
back and forth along the axis of that angle.
To adjust the compound slide, do these steps:
1. Loosen the compound cap screws shown in
Figure 14 to allow it to be rotated.
2. Rotate the compound slide to the angle
needed for your procedure.
3. Tighten the compound cap screws, and
check the angle again to make sure it did not
move during tightening.
4. Use the compound slide handwheel to move
the tool back and forth along the axis of the
new angle. Similar to adjusting the cross slide
handwheel, make sure the threads are engaging
and all backlash has been cleared before you set
the handwheel scale to "0", or it will not be
accurate.

Carriage Handwheel

The carriage handwheel (Figure 15)moves the
carriage left or right along the bed. This manual
control is necessary when setting up the
machine for turning or when manual movement
is desired during turning operations.

operations.

Carriage Lock

The carriage is supplied with a lock bolt on the
front right-hand side of the saddle (see Figure
15).
This bolt locks the carriage in place for
increased rigidity when making face cuts. This
lock bolt must be loosened before attempting to
move the carriage manually or with the power
feed.
