High quality, precision design
means years of trouble-free
service. Compare these
features with competitive
boring systems.
BB8000 Features
Versatile
“Mix and match” the individual components of
our system to components you already have...
you don't have to buy an entire system to get the
components you need.
Choose a plate mounting system with attached
bearing modules or a universal spider system for
a range of diameters. Support fixtures feature
roller bearings rather than bronze bushings.
Put the rotational
drive unit anywhere
on the 6 or 8 inch
diameter boring
bar.
Mechanical feed
units mount on
either end of the
bar. Axial feed
units feature a
quick-change
mounting system.
The feedscrew is mounted in the boring bar with
roller bearings and has replaceable end sections
so the entire leadscrew
doesn’t have to be replaced
if only the ends are dam-
aged.
Boring heads and boring-
facing head combos give
you a wide choice of ma-
chining options. Tool carrier
and counterbalance are
attached to the bar in a
modular stacking system so
you can bore a wide range
of diameters with just one
tool head.
Compact
The Climax Model BB8000 rotational drive unit
is compact, only 19 by 22 inches (482.6 x 558.8
mm) and weighs only 420 lbs (191 kg) with the
hydraulic motor attached. The standard mechani-
cal feed is not much larger than the bar diameter
itself and weighs less than 20 lbs. (10 kg).
Powerful
Hydraulic boring power offers a high power-
to-weight ratio and smooth, trouble-free power
transmission to the boring head. Your choice of
single or dual hydraulic motors combine with the
gear reduction of the rotational drive to produce
over 2500 ft.lbs (3,400 N•m) of boring torque.
