Adjustments
Headstock Alignment
Refer to Figures 11 and 12.
The headstock has been aligned at the factory
and should not require adjustment. However, if
correction is deemed necessary in the future,
the procedure is described below.
It is
recommended that only qualified service
personnel perform this adjustment.
1. Using a machinist’s precision level on the
bedways, make sure the lathe is level side
to side and front to back. If the lathe is not
level, correct to a level condition before
proceeding.
2. Re-test alignment if any leveling
adjustments were made.
3. From steel bar stock of approximately two
inches in diameter, cut a piece
approximately eight inches long.
4. Place two inches of bar stock in chuck and
tighten chuck. Do not use the tailstock or
center to support the other end.
5. Set up and cut along five inches of the bar
stock (see Figure 11).
6. Using a micrometer, measure the bar stock
next to the chuck and at the end. The
measurement should be the same.
7. If the measurements are not the same and
adjustment is required, loosen hex socket
cap screws (A, Figure 12) which hold the
headstock to the bed. DO NOT loose n
completely; some drag should remain.
8. Adjust two screw nuts (B) located at the end
of the headstock. Loosen one and tighten
the other. Make another cut. Keep adjusting
the screw nuts after each cut until the bar
stock measurements are the same.
9. Securely tighten headstock screws (A).
Tailstock Adjustments
Refer to Figures 13 and 14.
Quill Clamping Lever (A): Rotate clockwise to
lock the quill. Rotate counterclockwise to unlock.
The quill sleeve has a millimeter and inch scale
(1/8” graduations).
Quill Traverse Handwheel (B): Rotate
clockwise to advance the quill, counterclockwise
to retract it. The handwheel has a revolutio n
scale in 0.002” increments.
