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.
Split tool carrier
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.
