• use a sliding caliper to check alignment near
the sleeve "C" and the spindle "D"; adopt a
tolerance of 0.15 mm in all four directions.
• prepare a perfectly straight ground bar, with
an external diameter equal to the maximum
spindle bar passage and with a length equal to
the double coupling distance (see "B" in
section 4.4.3);
• place the bar in the guide channel and make it
slide forwards and backwards in the spindle,
until almost reaching the lathe collet area.
POSITIONING ADJUSTMENTS
After checking the alignment of the bar feeder with
either the thread or the bar, any required corrections
should be carried out.
Adjust the height by turning the screws of the feet;
carry out the lateral adjustments with calibrated
mallet blows on the bar feeder foot.
During this phase, any adjustment carried out during
the levelling phase should be preserved; therefore,
in most cases, it is necessary to find the correct
adjustment of the bar feeder position.
