ALIGNMENT
Alignment is obtained by
interposing a nylon yarn (ø 1 mm)
between the lathe collet and the
first feeding carriage, by proceeding
as follows:
• place a pierced bushing (A) in
the lathe collet;
• stretch the yarn between the
bushing and the hole in the 1st
feeding carriage (B).
• use a sliding calliper to check
alignment near the bushing (C)
and the spindle (D); adopt a
tolerance of
0.15 mm in all four directions.
It is also possible to carry out alignment by placing
a bar in the guides. Proceed as follows:
• prepare a perfectly straight ground bar, having
an outside diameter equal to the max. spindle
bar passage and a length equal to twice the
coupling distance (see item B paragraph 4.4.3);
• place the bar in the guide and cause it to slide
forwards and backwards in the spindle, until
almost reaching the lathe collet area.
