It is recommended to carry out the fine adjustment of steady
rest whilst the work piece is centre on the steady rest with
an offset along the positive X axis and Y axis of about 0.01
mm.
Minor errors (<= 0.02 mm) along the X axis can be
corrected as follows:

--

Undo and retract the clamping arm.

--

Undo the clamping screw on the fine adjustment
(do not remove).

--

Apply a low torque to set the 11 mm (brass)
adjustment nut according to the direction +/--.

--

Move forward and clamp the clamping arms.

--

Check the radial run.

--

Either re--adjust (clamping arms retracted) or
tighten the clamping screw (approx. 1 Nm).

Note:

In delivery condition the fine adjustment is in centre position
(steel bolt and adjustment nut in one level). The maximum
permissible adjustment travel of the steel bolt is +/-- 2 to 3
mm, depending on the size of the steady rest. In the pro-
cess, the centre moves by a maximum of +/-- 0.12 mm.

7 Adjust the centring position along the Y axis according to

the reading on the measuring gauge.

8 Open the steady rest and retract the arms.

9 The spacer units for the height adjustment of the Y axis

have been made thicker so as to be able to lower them per-
mitting the group to be adjusted to the height of the centring
points of the machine.
