6.5 BARS TO BE MACHINED - FEATURES AND PREPARATION
WARNING - CAUTION:
do not load bars having sizes different from those recommended by the
manufacturer (see reference table in § “VERSION DESCRIPTION”, Chap. 2).
Clean the bar surface before loading bars.
INFORMATION:
the bar must not have a straightness defect above 0.5 per 1,000.
Please find hereafter some advices to optimise the bar feeder performances.
Usually it is not necessary to perform preliminary operations on the bar ends, but to obtain
optimum results during loading, it is advisable to chamfer them.
6.5.1 BAR TO BE MACHINED - SOLID BARS
Make sure that there is not too much rag on the
front end, which might hinder from entering the
lathe collet.
Check that there is not too much rag on bar rear
end, which might hinder insertion in the bar pusher
collet. In any case, to improve operation during this
phase, we advise to chamfer the bar as shown in
the figure.
If bars with front remnant ejection have to be
machined, we advise to chamfer the bar rear end as
shown in the figure.
