BB8000 Features
High quality, precision design
means years of trouble-free
service. Compare these
features with competitive
boring systems.
Versatile
“Mix and match” the individual components of
our system to components you already have...
you don't have to buy an entire system to get the
components you need.
Choose a plate mounting system with attached
bearing modules or a universal spider system for
a range of diameters. Support fixtures feature
roller bearings rather than bronze bushings.
Put the rotational
drive unit anywhere
on the 6 or 8 inch
diameter boring
bar.
Compact
The Climax Model BB8000 rotational drive unit
is compact, only 19 by 22 inches (482.6 x 558.8
mm) and weighs only 420 lbs (191 kg) with the
hydraulic motor attached. The standard mechanical feed is not much larger than the bar diameter
itself and weighs less than 20 lbs. (10 kg).
Mechanical feed
units mount on
either end of the
bar. Axial feed
units feature a
quick-change
mounting system.
The feedscrew is mounted in the boring bar with
roller bearings and has replaceable end sections
so the entire leadscrew
doesn’t have to be replaced
if only the ends are damaged.
Boring heads and boringfacing head combos give
you a wide choice of machining options. Tool carrier
and counterbalance are
attached to the bar in a
modular stacking system so
you can bore a wide range
of diameters with just one
tool head.
Powerful
Hydraulic boring power offers a high powerto-weight ratio and smooth, trouble-free power
transmission to the boring head. Your choice of
single or dual hydraulic motors combine with the
gear reduction of the rotational drive to produce
over 2500 ft.lbs (3,400 N•m) of boring torque.

Setup & Operation
Easy setup and operation
maximize your uptime.
There are many ways to set up the Model
BB8000 Boring Machine, depending on the
application and clearances around the work
area. To bore the surface you are mounting on,
standoffs welded on the workpiece give you
clearance for making tool head adjustments.
Insert the boring bar, supported on wooden Vblocks, in the bore and slip the mounting spider/
bearing plates on each end. Lift the bar to bore
center and attach the mounting spiders to the
workpiece, either internally or externally. Final
centering adjustments are made with the jacking
screws on the bearing plates.
Vertical mounting of the Model BB8000 Portable Boring
Machine is used to bore a large metropolitan water system
pump.
Horizontal setup of the boring bar with ID mounting spiders in a
large turbine. Surface mounts or ID mounts are available.
Individually adjustable clamping feet allow precise
alignment of the ID spider mounting system.
Once the bar is accurately positioned, move
the rotational drive unit into place and lock it to
the bar with two locking collars. Tie-down arms
keep the rotational drive from turning during
boring operations.
Next, place the axial feed unit on either end
of the bar, install the split tool carrier, spacer
blocks and tool head on the bar and you are
ready to make your first boring pass. Actual
boring operations are simply a matter of
adjusting the boring depth at the cutter, setting
the feed rate and direction and starting the
machine rotation.

Components & Accessories
components allow
you to choose
exactly what you
need for your
application.
The Model BB8000 Portable Boring
Machine is designed to meet as
wide a range of applications as
possible. Select only the components you need. A complete
machine consists of the following:
1. Rotational drive unit
2. Drive motor(s)
3. Axial feed unit
4. Boring bar
5. Tool head and carrier
6. Two support spider systems
7. Hydraulic power unit
8. Tool kit
9. Feed control unit
Rotational drive unit Compact unit
weighs 420 lbs. (191 kg) with a 20:1
double enveloping worm gear reduction. Mounts anyplace on 6" (152.4
mm) or 8" (203.2 mm) diameter bars.
Collets are needed with the 6" bars.
Integral cooling fans require 115 v
power.
Boring bars 6" (152.4 mm) and 8"
(203.2 mm) dia. bars feature a full
length, in-bar leadscrew with replaceable ends. Collets are needed
with the six-inch diameter bars. End
caps allow attachment of axial feed
units. Bar lengths are 8 ft (2.44 m) to
20 ft. (6.1 m). Longer bars available
on special order.
Mechanical
axial feed
unit A revers-
ible automatic
feed with
manual control
for setting feed
rate and feed
direction. Feed rates are variable
from .003 to .040" (.08 to 1.01 mm)
per revolution.
Tool carrier The tool carrier is a
split design that may be attached
anyplace on the bar. Boring heads
may be attached on one side for
single tool boring or both sides for
boring with twin tools.
Mounting system Various combinations of ID or end mounted
support systems and roller bearing
assemblies are available.
Manual facing
head Attaches
to tool carrier/
spacer blocks in
place of manual
boring head. Has
a 5" (127 mm)
mechanical radial
feed stroke for
facing operations.
Hydraulic power units Variable
displacement piston pump hydraulic
power units are available in 15 or 25
hp (11.2 to 18.6 kW) models. These
compact units are designed specifically for portable applications.
Special accessories
Taper-cutting attachments, extra long
bars, flame-cutting attachments,
electric and CNC axial/radial feed
units, remote
boring/facing
head, and other
adaptations have
been designed
for special
customer applications. Ask your
Climax sales
representative for
more information.
Drive motors
various displacements are available
for the smoothest power transmission in most boring operations. Use
single or dual motors depending on
the amount of torque needed. Electric
drive motors are also available.
