Positioning
Headstock
The head tilts 45° left or right and is mounted to
a turret that rotates 45° left or right around the
column (see Figures 25–26).
Any time the head has been tilted or rotated, you
must tram the spindle with the table when setting
the headstock back to the 90° position. This is the
only way to ensure precision milling results later.
Refer to Tramming Spindle on Page 50 for more
information.

Tilting Head Left/Right
1.
DISCONNECT MACHINE FROM POWER!
2.
Use a 17mm wrench to loosen the four tilt
locking nuts on either side of turret (see
Figure 27). Do not remove locking nuts.
Note: The head is heavy. Have an assis-
tant help to support its weight as you make
adjustments.
3.
Manually tilt head to left or right. Use head tilt
scale (see Figure 27) to determine angle.

4.
Retighten all tilt locking nuts to secure head.
Note: The tilt locking nuts shown in Figure
27 are threaded onto T-bolts that travel in a
circular slot during head tilt adjustment. When
tilting head, it is possible for these T-bolts to
jam in the slot preventing movement of head.
If this happens, gently rotate each nut, one at
a time, until you free up the jammed T-bolt.
Then continue to tilt head to desired position.
Always lock head firmly in place after tilt-
ing or rotating it. Unexpected movement of
head during operations could cause dam-
age to cutter or workpiece.
