ALIGNMENT
The alignment is obtained by fitting a nylon thread
(ø 1 mm) between the lathe collet and the first
feeding carriage, proceeding as follows:
• place a drilled bush (A) in the lathe collet;
• stretch the thread between the bushing and the
hole in the first feeding carriage (B).
• check with a sliding caliper, the alignment near
bushing (C) and spindle (D); use a tolerance of
± 0.15 mm in the four directions.
It is also possible to carry out the alignment by
placing a bar in the guide channels. Proceed as
follows:
• 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 paragraph
4.4.3);
• place the bar in the guide channel and cause it
to slide forwards and backwards in the spindle,
until the lathe collet area is reached.
