Tool post
Compared to turret lathes, a flat-bed lathe with a tool
post can often be more rigid and stable. This results in
the capability of holding larger and longer boring bars.
The limitation of the machine in this case can be the
tool post, the size of the machine and the rigidity in its
design.
The stability of the machine slides and gibs is an impor-
tant factor for achieving good results when holding large
Silent Tools boring bars with long overhangs.
The weight increases dramatically with increased bar
size:
• Diameter 100 mm = 88 kg
• Diameter 120 mm = 140 kg
Split holder for 300 mm bar diameter. Distance between the
cross slides is 1200 mm (4 x dm
m
).
Minimum 4 x bar diameter
