Mill head – angle setting
1. Setting the angle:
a. Loosen the three ram adapter clamp bolts
(E, Figure 11). There is no need to loosen the
bolts more than one-half (1/2) turn to allow
tilting.
Figure 11: Mill head movement
b. Support the mill head with your free hand.
Press upward on the spindle when changing
the angle.
c. Turn ram adapter worm nut (F, Figure 11) to
tilt head forward and backward. Use scale on
ram adapter to locate desired angle.
2. Returning to upright position:
a. When returning mill head to full upright
position, support head by upward pressure on
the spindle as you turn worm nut.
b. Check to make sure mill head is
perpendicular to worktable.
c. Set up a dial indicator in a collet and secure
using the draw bar (refer to Figure 10).
d. Put spindle drive in neutral.
e. Set dial indicator plunger on worktable. Zero
the indicator.
f. Rotate spindle 180 degrees. (When rotating,
raise dial indicator plunger by hand to prevent
it from dropping into the table T-slots).
g. Read dial indicator. The indicator should
read zero. If not, loosen adaptor bolts (E,
Figure 11) and reposition mill head.
h. Recheck perpendicularity using dial
indicator. Repeat procedure above until dial
indicator reads zero in both positions.
i. When indicator reads zero, tighten ram
adapter clamp bolts (E, Figure 11).

Ram movement
12.8.1
Ram position fore and aft
Refer to Figure 12.
1. Loosen handles (G, Figure 12) that lock the
ram to its ways.
2. Turn lever (H) to slide ram.
3. When desired position is reached, lock
handles (G) securely.
Figure 12: Ram positioning
12.8.2
Rotating ram on turret
Refer to Figure 12.
Make sure machine base is
secured to floor before repositioning ram. The
center of gravity can shift enough to cause
machine to tip over, resulting in serious injury
to operator and damage to machine.
1. Loosen four turret lock bolts (J, Figure 12) that
clamp the ram to the top of the base. One-half
(1/2) turn should be sufficient to allow the
turret to move.
Note:
Use gentle hand pressure to avoid rapid
movement.
2. Swing the ram until spindle is in desired
position. Use scale (I) on turret for degree
measurement.
3. Tighten the four turret lock bolts (J).
12.9
Table Movement
Refer to Figure 13.
A.
Longitudinal Movement
(A, Figure 13) -
handles located on opposite ends of table;
control the X-axis.
B.
Stops
(B) - located on front of table; limit how
far table travels in either direction.
C.
Table Locks
(C) - located on front of saddle;
used for locking table in position.
D.
Cross Feed Movement
(D) - located on front
of knee; controls the Y-axis.
E.
Knee Handle
(E) - located on corner of knee;
controls the Z-axis.
