The compact Model BB7000 offers big
job boring capability on-site. Modular
components allow you to choose exactly
what you need for your application.
Modular versatility.
• Bearing support system consists of
three independent mounting fixtures
that can be used alone or in different
combinations. If space is limited, mount
the bearing cartridge directly on the
workpiece. Or use the bearing cartridge
with the spacer flange and/or the
mounting spider.
• Position the rotational drive unit
anyplace along the bar.
• Axial feed unit mounts on either end of
the bar.
Compact.
• Rotational drive unit is only 12" by 17",
weighs only 160 lbs (72.6 kg) with the
hydraulic motor attached.
• Standard mechanical axial feed is not
much larger than the bar diameter and
weighs less than 20 lbs (9.1 kg).
Powerful.
• Compact hydraulic power unit designed
specifically for portable machining.
• High power-to-weight ratio
• Smooth, trouble-free power transmission
to the boring head.
• Standard boring bar package produces up
to 11 hp at the bar at 60 rpm.
Designed with the operator in mind.
• Easy to operate and maintain.
• Roller bearings instead of bronze bushings on support fixtures.
• Split tool carrier for easy mounting on the
bar.
• All axial feed units are interchangeable
• All axial feed units feature a quick-change
mounting system.
• The leadscrew has replaceable end
sections.
Standard machine (A)
A standard machine package consists of:
• Rotational drive unit
• Mechanical axial feed unit with infinitely
variable feed rate and feed direction
selector options of forward, neutral or
reverse.
• Two, three part mounting spider sets with
roller bearing cartridge, tool carrier-boring
head set for boring 8-inch to 40-inch
diameters, depending on configuration.
• Control pendant with power unit start/
stop, bar rotation on/off and rotation jog.
• A 15 or 25 hp hydraulic power unit with all
hoses and fittings.
Optional facing head (B)
The facing head features mechanical radial
feed with 4" stroke. Feed rate is adjustable
up to .010". Assembly mounts onto either
the 4" or 5" tool carrier assembly. On the
4" tool carrier the facing head will face 9.5
to 35 inches diameter.
CNC option (C)
CNC options are available. Contact the
factory for information.
Optional electronic axial feed unit (D)
Add digital readout control capabilities and
program axial automatic feed stops to the
Model BB7000. The electronic axial feed
features a reduction leadscrew gearbox, slip
rings for electrical impulse pickup and two
interchangeable feed motors that provide
infinitely adjustable feed rates from .026 to
4.8 inches per minute. The pedant provides
control of the boring operation and the
power unit with the following:
• Axial feed direction selector (forward ,
neutral, and reverse)
• Axial feed rate selector
• Bar rotation start/stop
• Power unit start/stop
• Digital tool position readout. This option
allows the operator to bore to a preset
distance without the need for visual
inspection.

Operation & Applications
Easy setup and
operation help you
maximize your
uptime.
There are several ways to set up the Model
BB7000, depending on the application and
clearances around the work area.
Weld standoffs to the work piece around
the bore, positioned to match the slots on
the mounting spiders. Next, lift the bar into
position, set it on wooden V-blocks and
position in the bore. You can now slide the
mounting spiders and bearing plate onto
each end of the bar, lift the bar to center
position and bolt the spiders to the
standoffs.
Once the bar is attached to the standoffs
you can critically align it using a dial
indicator and the jacking screws on the
bearing plates. When
the bar is centered,
slip on the rotational
drive unit and lock it
in place on the bar
with the two
clamping collars. Tie
down the torque
arms on the
rotational drive unit
to prevent it from
rotating. Place the
axial feed unit on
either end of the bar,
install the proper
spacer blocks and
cutter on the tool head and you are ready to
make your first boring pass.
Actual boring operations are simple: adjust
the boring depth at the cutter, set the feed
rate and direction and start the machine
rotation.
Manually adjusting the boring head position.
Applications throughout industry
MarineMany marine repair operations
can be simplified by using the Model
BB7000. Line bore a ship's rudder pins or a
submarine's diving planes or the main
bearing seats in a large marine diesel
engine. Turbine housings and engine block
cylinder sleeves can be bored in place. Ship
stern tubes are an ideal application for a
portable boring bar. Worn areas can be built
up by metalizing and then re-boring to
original dimensions. Submarine hatches
and torpedo tubes can be re-bored with the
portable boring bar.
IndustrialBore large gearboxes, large
hydraulic cylinders, plates, or vessels
without removing them. Stamping presses
Boring in a steam turbine.
with worn bearing seats are ideal candidates
for line boring. Buildup the bore and reboring to original dimensions. Line bore
multistage pumps by separating the pump
halves, removing the impeller system,
installing the portable boring bar, replacing
the top half of the pump and re-boring
without removing the pump.
HydroelectricHydro dams use the Model
BB7000with long bars for boring tainter
gate pivot pin holes eroded by water
cavitation. The bottom pins of some gates
have blind holes that require the use of the
digital readout/auto stop option of the
Model BB7000.
Canal locks The lock gate hinge pins of the
Panama Canal are line bored using the
Model BB7000 Portable Boring Bar.
Metropolitan water districts Repairs or
modifications on pumps and turbines can
be made in place... sometimes saving the
cost of the machine with only one or two
jobs.
