BB6000 Design Features & Benefits
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.
Compact
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.
