BB6000 Design Features & Benefits
Bore 6-inch to 36-inch diameters on site...
Modular versatility
• The rotational drive unit mounts anywhere on the
bar for maximum setup flexibility.
• Feed unit attaches to either end.
• Optional ID mounting spiders have jacking
screws for centering.
• 3-arm or 4-arm end-mount bearing supports.
• When space is really tight, mount the bearing
cartridge right on the workpiece.

The Model BB6000 is the smallest in our line of
traveling head portable boring bars (the smaller
BB3000 and BB5000 models feed by moving the
bar). Boring diameter range is 6" to 36" (152.4 to
914.4 mm). The compact hydraulic rotational drive
unit provides almost 1300 ft•lb of torque.
Compared to competitive machines, the rotational
drive unit provides a high power-to-weight ratio.
Efficient design and cast aluminum housing keep
the rotational drive weight at only 110 lbs. (50 kg),
with the hydraulic motor attached. The compact
mechanical axial feed unit is only a little larger in
diameter than the bar itself.

Powerful
Hydraulic power provides smooth and trouble-free
power transmission to the boring head. Several
hydraulic motors are available to provide a range
of rpm and torque. The Model BB6000 requires a
minimum 5 hp hydraulic power unit.
Rugged, practical design
• Support fixtures feature ball bearings rather than
bronze bushings.
• Split tool carrier is easy to mount on the bar.
• Tool head spacer blocks can be added to
increase the boring diameter.
• The leadscrew is mounted in the boring bar with
roller bearings, not bushings.
• Facing heads, taper boring systems, and other
accessories increase the versatility of the
machine.
• Easy setup and operation.
• High quality, precision design means many years
of trouble-free service.

Setup & Operation
Easy setup and
operation help
minimize downtime.
There are several ways to set up the Model
BB6000 depending on the application and
clearances around the work area. If you have to
mount one of the bearing supports on the surface
that needs boring, weld standoffs on the workpiece
to allow access for tool adjustment.
• Insert the bar into the bore, allowing it to rest on
wooden V-blocks.
• Slip the bearing support assemblies onto each
end.
• Lift the bar to bore center and into the support
spiders attached to the workpiece, either
internally or externally.
Face mounted 4-arm mounting spider for up to 36" (914.4mm)
dia. Torque arms prevent rotational drive turning.
Three-arm mounting assembly for up to
20" (508 mm) diameters.
• Make final centering adjustments with the jacking
screws on the bearing plates.
• Once the bar is accurately positioned, slip the
rotational drive unit in place and lock to the bar
with the two locking collars.
• Tie-down arms are provided to secure the
rotational drive and keep it form turning during
boring operations.
• Place the axial feed unit on either end of the bar.
• Install the tool carrier, spacer blocks, and one or
two tool heads.
The machine is ready to make the first boring
pass. Boring operations are simply a matter of
adjusting the boring depth at the cutter, setting the
feed rate, and engaging the feed in forward or
reverse mode. The hydraulic power unit is turned
on and bar rotation is started with the control
pendant.
Speed wrench or portable drill motor can be used to move tool head from either end
of the bar, with or without the axial feed unit attached.
Tool head accepts either HSS tool bits or
carbide insert holders as shown here.

Components & Accessories
Modular components allow
you to choose exactly what
you need for your application.
The Model BB6000 Portable Boring Bar is
designed in modules for as wide a range of
applications as possible. Select only those
components you need for your particular situation.
A complete machine must have the following
components to be functional:
1. Rotational drive unit
2. Hydraulic drive motor
3. Axial feed unit
4. Boring bar
5. Tool carrier
6. Boring head
7. Hydraulic power unit
8. Bearing supports (2)
Rotational drive unit
unit mounts anyplace along the bar, and weighs
86 lbs (40 kg) with a 6:1 gear reduction. Clamp
collars lock the unit to the bar securely. Torque
arms keep unit from turning with the bar.
Maximum torque at the bar with the largest
displacement hydraulic motor is almost 1300 ft•lbs
(1768 N•m). Fits any 3.5" (88.9mm) diameter bar.
Compact cast aluminum
Drive motors
motors in various
displacements are available
and provide the smoothest
power transmission for most
boring operations. Standard
SAE flange mount reversible
motors with 2-bolt mounting.
Hydraulic
Tool carrier
may be positioned anywhere
along bar. Way wipers are
provided for carrier and bar
protection. A threaded key
drives the carrier along bar
during boring operations. If
you are using this carrier with
an existing bar, be sure the
key threads are compatible with the leadscrew.
Boring heads
are available in two sets that
cover 6" to 24" (152.4-609.6
mm) and 6" to 36" (152.4-
914.4mm) respectively. Boring
heads mount directly to both
sides of tool carrier with or
without spacers. Use boring
heads alone or in tandem.
Spacers increase boring
diameter. Heads accept .5"
(12mm) square tool bits or 1"
(25.4mm) square indexable
carbide tooling.
Facing head
tool carrier in place of the boring head. The unit
can face from 10.5" to 36" (267-914.4mm) in 4"
(101mm) increments.
Mounting system
mounted bar support systems are available. Selfaligning bearings and jacking screws for centering
allow fast setup. ID mounts are available for 12"
to 36" (304.8-914.4mm) dia. End mounted bearing
support assemblies are available for 12" to 38"
(304.8-965.2mm) mounting diameters.

Boring bars
dia. with full length lead screws and replaceable
ends. Bar lengths from 5 to 12 ft (1.5-3.7m) with
longer bars available on special order.

customer applications.
Hydraulic power units
piston pump hydraulic power units are available in
5 or 10 hp (3.73 or 7.46 kW) models. These are
compact units designed for portable machining
applications.
