BB7100 BORING MACHINE
Packing big boring capability into a compact, modular
machine, maximizing efciency and minimizing downtime.
Powerful Yet Compact
• Take the power of a stationary machine to the
job site to solve tough machining challenges in
record time.
• Using 11.3 in
3
(185 cm
3
) Hydraulic motor,
produces
2280 ft-lbs (3090 N•m) of torque at the
bar, at 29 rpm.
• Compact, modular components, many which
can be lifted by hand, allow fast, easy setup,
maximizing efciencies, and minimizing
downtime.
Versatile and Flexible
• Huge machining range bores from 10.25 - 57.5
inches (260.4 - 1460.5 mm) in diameter, and
faces from 9.6 - 62.5 inches (243.8 - 1587.5
mm).
• ID and End mount bearings feature spherical
taper-lock roller bearings.
• End mount can be ne adjusted by +/- 0.625
inches (15.9 mm) to center the bar.
• Optional dual action boring/facing arms
increase facing range, and allow for both
boring and facing without switching equipment.
Full-length square ways on boring/facing arms
allow for quick positioning anywhere along
the arm. Attaches to the net t tool carrier by
compression-clamping, to provide maximum
tool stability.
• Machine is highly adjustable. The tool carrier,
half nut, alignment of boring/facing arm,
and tool carriage can each be adjusted to
maximize machining performance.
• With leading & trailing boring head conguration,
2 boring heads can be used simultaneously.
• For even greater facing range and longer
continuous stroke, the new boring/facing arms
are available. Setup is quick & easy, featuring
industry standard quick-change tooling for
both boring and facing operations.
• Highly versatile tool holder block accepts
industry standard tooling with a nominal 1 inch
(25.4 mm) square shank.
• Tool post on the boring/facing arm can be
rotated to provide maximum exibility in
machining setup (including some cantilevered
congurations).
• Net t tool carrier can be clamped to bar for
facing operations. For boring operations,
carrier can be adjusted to remove clearance
between carrier and the bar. This exibility
also ensures maximum rigidity for either
operation
• Net t tool carrier designed with a split frame
to simplify installation on the boring bar. It can
be congured to use either the boring head set
for boring or facing, or the new boring/facing
arm assembly.
High Quality Design
• Features a uniquely-designed modular tool
carrier which provides a new level of strength
and rigidity by channeling machining forces
directly to the boring bar through strategically-
located adjustable guide shoes.
• Chromed bars, straight to within 0.001 inch
per foot (0.0254 per 304.8 mm)
• Gun-drilled bars with optical targets available.
• Adjustable, removable half nut increases net
t tool carrier exibility. Easy removal of tool
carrier allows for machining of multiple bores.
• Backlash adjustment nut allows in-the-eld
adjustment to eliminate backlash in the tool
carrier, and extend the life of the machine.
