Headstock Travel
(Z-Axis and Rotation)
Headstock height is adjustable in the vertical Z-axis to
accept large workpieces. For unique milling operations,
the headstock can be tilted right or left between 0° and
90°. Your mill has a dovetailed slide that allows you to
reposition the headstock and change tooling without los-
ing your alignment with a hole or milling path.
To raise or lower the headstock, do these steps:
1. Unlock the headstock slide lock lever shown in
Figure 12.
2. Turn the Z-axis handwheel shown in Figure 13 to
raise or lower the headstock, then lock the head-
stock slide lock lever.
Note: Milling with the quill fully extended, can
cause tool chatter. For maximum spindle rigidity
when milling, lower the headstock, keep the spin-
dle retracted completely with the quill lock lever
locked, and the fine feed lock knob tightened.
To tilt the headstock to the left or right, do these
steps:
1. DISCONNECT THE MILL FROM POWER!
2. Using a 17mm wrench, loosen both headstock tilt
lock nuts (Figure 14).
3. Insert a 6mm hex wrench into the index pin release
port (Figure 14), and turn the hex wrench clockwise
to disengage the spring-loaded index pin from the
headstock.
4. While watching the tilt scale, rotate the headstock
to the required angle, and retighten the tilt lock
nuts to hold the headstock in place.
Note: The index pin is spring loaded and serves
only as a quick way to return the headstock close
to zero. It is not intended to be an absolute zero
degree stop. No other index holes exist at other
angles in the headstock.
