The primary challenge for most on-site maintenance is that repairs are often done under difficult conditions. CLIMAX Portable Machining & Welding Systems leads the way in promoting the safe use of portable machine tools. Safety is a joint effort. As the operator of this machine, you are expected to do your part by closely examining the job site and following the operating procedures outlined in this manual, your own company rules, and local regulations.
MACHINE SPECIFIC SAFETY PRACTICES All aspects of the machine have been designed with safety in mind. Following are safety practices that you should keep in mind when using the CLIMAX BB7100 Boring Machine. Personal Protective Equipment (PPE) Metal Fragment Hazard...
SAFETY WARNING SYMBOLS The purpose of product safety signs and labels is to increase the level of awareness to possible dangers. Safety Alert Symbols indicate DANGER, WARNING or CAUTION. These symbols may be used in conjunction with other symbols or pictographs. Failure to obey safety warnings can result in serious injury.
Due to the unique nature of portable machining applications, identifying one or more hazards that must be addressed is typical. When performing the on-site risk assessment, it is important to consider the Portable Machine Tool and the workpiece as a whole. Page 4 BB7100 Operating Manual...
RISK ASSESSMENT CHECKLIST The following checklist is not intended to be an all-inclusive list of things to watch out for when setting up and operating this Portable Machine Tool. However, these checklists are typical of the types of risks the assembler and operator should consider.

INTRODUCTION This manual describes how to use your Model BB7100 Portable Boring Machine. Every part meets CLIMAX’s strict quality standards. For maximum safety and performance, read the entire Operating Manual before using the portable boring machine. P/N 55769, Rev. 4...
INSPECTING THE MACHINE Your CLIMAX product was inspected and tested prior to shipment, and packaged for normal shipment conditions. CLIMAX does not guarantee the condition of your machine upon delivery. When you receive your CLIMAX product, perform the following receipt checks.
SETUP WARNING When setting up or servicing the machine, disconnect the power source and lock the machine out. Failure to do so could result in accidental start-up and seriously injure you or others. Crane or Hoist A hoist, crane, or other lifting device is vital in the setup of the machine. Only use an apparatus that allows smooth operation with fine adjustment, such as a hydraulic lift or 2- stage winch.
6. Clean the bar with solvent to remove dirt and chips. CAUTION The bar is not hardened. To prevent bar damage, do not strike the bar against the bearing supports or against the work piece. Page 12 BB7100 Operating Manual...

7. Place the boring bar into the bore(s) to be machined. Placement of the Boring Bar in the bore 8. Slide bearing supports onto each end of the bar. Attaching bearing supports 9. Using a hoist, hold the bar and bearings in the center of the bore. 10.
9. Slide the boring bar through all bearing assemblies. 10. Lock the bar in place by tightening the bearing cartridge nut. 11. Insert the bearing key tool between the groove in the boring bar and the groove in the bearing tapered sleeve. Page 14 BB7100 Operating Manual...
Page 23
17. Position a dial indicator to measure the concentricity between the boring bar and the bore 18. Adjust the screws in the bearing support adjusting blocks until the bar is centered. CLIMAX recommends using at least two support assemblies to obtain machine stability. P/N 55769, Rev. 4...
To feed the tool head AWAY FROM the axial feed, turn the lever away from the bar. The feed is in NEUTRAL when the knob and the lever are perpendicular to the bar. Axial Feed Direction Page 16 BB7100 Operating Manual...
IMPORTANT If the axial feed unit is moved to the opposite end of the bar, the feed direction will reverse. Check feed direction before operating the boring bar. Setting the Axial Feed Rate Axial feed rate is adjustable and variable from 0.003" to 0.025" (0.07 to 0.63 mm) per revolution.
When the servo is engaged, the drill socket will not fit into the port. Drawings (P/N 81709) are found in the Exploded Parts and Views on page 41. Page 18 BB7100 Operating Manual...
Rotational Drive Setup The rotational drive can be placed anywhere along the boring bar. CAUTION The boring bar is not hardened. To prevent bar damage, do not strike the bar against the bearing supports or against the work piece. To setup the rotational drive 1.
Page 28
11. Connect the hydraulic lines between the motor and the hydraulic power unit. CAUTION To avoid damaging the hydraulic power unit pump, connect the hydraulic motor to the power unit before plugging in and turning on the power unit. Page 20 BB7100 Operating Manual...
Installing the Facing and Boring Arms to the Boring Bar To mount the tool carrier 1. Check the bar for nicks or cuts. Dress the bar smooth, if necessary. A bar with nicks or gouges can damage mating parts beyond repair (including the axial tool carrier and rotational drive unit).
1. Do not remove all the screws 2. Remove the screws on each end of the brass nut 3. (If there is too much play in the brass nut, the center set screw can be tightened) Page 22 BB7100 Operating Manual...
Install the Slide Arm onto the Tool Carrier 1. Using a device such as a crane, place arm onto tool carrier flush with carrier surface as shown. IMPORTANT Always use the lifting eyes when lifting the arms. The rotating lifting eyes provide the flexibility and safety during setup operations.
0.001" change in diameter. The dove tail adjustment set screws are set to the correct load by CLIMAX and should not be necessary to re-adjust them. These set screws have Vibratite-VC3 in order to avoid losing tension during vibration. The lock also has this compound, and it might be necessary to re-apply some every once in a while, if necessary.
Boring head setup 1. Select the required parts using the “Boring head tool range” table. 2. Using the drawing as a guide, assemble the stack up blocks on to the tool carrier symmetrically on both sides of the tool carrier, from tallest to shortest. 3.

Starting the machine The CLIMAX BB7100 is intended for operation at varying rates of rotation and feed. The rotation speed is controlled by varying the output from the Hydraulic Power Unit (HPU). The feed rate of the mechanical unit is controlled manually from the feed unit.
5. Operate the boring bar as described in “Starting the machine” on page 29. CAUTION The bar is not hardened. To prevent bar damage, do not strike the bar against the bearing supports or against the workpiece. Page 30 BB7100 Operating Manual...
Using the Remote Pendants Operator controls for the machine are located on the remote pendants, described below. CAUTION The bar rotation and the axial feed are independent of each other. Be sure the feed is OFF when the bar is not running. Feed Pendant The following is a description of the Feed Pendant controls: Symbol...
Disassembly To disassemble the machine 1. Turn off and lock out the hydraulic power unit. 2. Disconnect the hydraulic hose from the motor. 3. Remove the tool bit or carbide cartridge from the tool head. Page 32 BB7100 Operating Manual...
4. Remove the tool head and tool carrier. 5. Remove the axial feed from the bar. 6. Securely support the boring bar, bearing supports, and rotational drive with hoists. 7. If the rotational drive is between bearing support assemblies, remove one support first by doing the following: ...

14. Loosen the bearing cartridges. 15. Place a clean wooden “crib” in the bottom of the bore. 16. Remove the bearing support(s) from the work piece. 17. Slide the bar out of the bore using the crib. Page 34 BB7100 Operating Manual...
Filling the gearbox with oil 3. Fill the gearbox (through the fill hole) until oil comes out the level hole. 4. Replace the level plug. 5. Add one more quart of oil. 6. Replace the fill plug. Page 36 BB7100 Operating Manual...
Bearing support End-mount bearing support assemblies Periodically grease the bearing cartridge by pumping grease through the grease fitting in the housing. Before storage, lightly oil the assembly to prevent rusting. ID-mount bearing support assemblies If the jaws stick inside the blocks, pull the jaws out and grease the worm gears inside the blocks.
STORAGE Proper storage of Model BB7100 Portable Boring Machine will prevent undue deterioration or damage. Before storing the machine, clean it using solvent to remove grease, metal chips, and moisture. Spray the machine with a moisture-protective coating (LPS1 or LPS2 for short-term storage, LPS 3 for long-term storage) to prevent rusting.
SPARE PARTS Parts listed below include items most frequently replaced due to wear, loss, or damage. To avoid unwanted down time you may choose to stock the items listed.
