BOREWELDERS

From the BOA-408i base to the fully optioned BOA-408i S5, this patented bore welding system has been the top selling design since it was released. For bores, faces and OD's ranging in size from under 1" (25mm) to over 60" (1.5m) in any position, the BOA-408i has you covered. Ask about the free-trial and trade-in programs too.

The BOA-M1 bore welder is literally the most compact bore welder available, period. Stuck welding up on the undercarraige of a wheel loader? How about the a worn bore on a log yarding machine where the boom attaches to the base? The 2.5 pound BOA-M1 is ready for the job. With an entry price of under $4900. these bore welders are amazing and fully upgradable with the ultra precise, compact stepper auto-drive sytem for full automation.

Designed specifically for ultra long duration welding at very high amperages, the BOA-550HD standard setup can run 16" (410mm) continuous stroke and will reach 6 feet (1.8m) deep into a bore. Great for those large jobs such as those found on rock crushers or power generation, the BOA-550HD can weld up bores, faces and outside diameters over 6 feet (1.8m) and well beyond with optional accessories.  

LINE BORING SYSTEMS

BOA-C45 LineBore System

(premium pass-thru drive)

Simple, rugged, precise and very easy to use the BOA-C45 is a staple in any shop or on any service truck working on the bores found on most earth moving machines. The BOA-C45 line boring package is capable of machining bores & faces from 1" (25mm) to 14" (356mm) and boasts a number of features that are unique such as quick-change feed screws (available in a variety of lengths) , pass-through compact drive design (offering amazing setup versatility), variable feed rate, reversible feed direction and rotation and the all-new star drive interface. Of course, like all our pass-through design line bore systems, tune-able bar support bearings & dual tool ports are standard in the bars offering easy & precise "tool-in" bore measurements and final cut sampling measurements. It is these many unique features that makes the BOA-C45 simply the best, quickest and most accurate systems available at any price for most any heavy equipment bore repairs. (now available with electric or hydraulic drive)

BB6 LineBore System

(premium pass-thru drive)

The BB6 line boring system is designed for a wide variety of diameters. Capable of working on faces and bores from 1.5" (38mm) to 24" (610mm) and able to operate with the feed gearbox remotely mounted from the rotational gearbox, this system is big, tough and versatile. Like the BOA-C45 , the BB6 has a pass-through drive design, may be ordered with shorter or longer feed screws and may be equipped with the unique snap-ring groove cutting system or morse-taper end bars allowing all sorts of options including blind end machining. (available with electric or hydraulic drive)

AM7 LineBore System

(premium pass-thru drive)

This hydraulic-drive boring system is similar to the BOA-C45 in that it has a pass-through drive and utilizes a larger main bar allowing machining on bores as large as 30" (762mm). The rotational feed and axial feed are integrated on this unit and a micro bar setup can be added which allows the AM7 to machine as small as 1" (25mm) diameter bores. Dual tool ports are also standard on the two main (large) diameter bars in this package.  

150 Series LineBore System

(economy end-mount drive)

This is an electric drive boring system that rotates and feeds the bar from the end of the bar. Bar does not have the option of passing through the drive. The 150 with accessories can machine as small as 1" (25mm) and as large as 6" (152mm)  Package available at under $3300. USD.   This is the industries lowest price boring system. Add a bore welder and you will be under $8995. USD.

POPULAR BORE

REPAIR ACCESSORIES

We manufacture a number of accessories for you to use with your line boring and bore welding system. Popular accessories include:

ID BORE MEASURE GAGE KIT - offers you the easiest way to accurately measure the bore you are repairing through the secondary tool port on your boring bar. Works in 1/2" and 3/8" tooling ports, for bores up to 14" diameter. (order #K92.10) See demo here

ID BORE MEASURE GAGE KIT TIGHT BORE VERSION - similar to the standard kit above, but is designed to collapse  down to the bar diameter enabling the accurate measurements of bores which are much closer to the actual boring bar diameter. (standard ID bore measure requires 1/2" (12mm) clearance over bar dia) (order #K92.20)

PRECISION TOOL BIT ADJUSTER KIT - Used in with your ID bore measure gage kit, This kit offers you the most accurate and positive way to adjust your cutting tool for a precise final cut. (order #K93.26) See demo here

ADJUSTABLE BASE PACKAGE - This package offers you more adjustment of your boring bar supports. Very handy when mounting the unit to uneven surfaces and/or when working on excessively worn bores. Comes with (2) bases to work with your (2) standard one-arm supports. (order #K94.21)

MORSE TAPERED BAR OPTION -

We offer our boring bars with morse tapers machined in the ends. This is handy for a variety of specialty work and allows bars to be coupled together (using our optional coupler kit) or allows your boring bar system to machine right off the end of the bar for blind machining or drilling. (order # varies depending on bar. We also modify existing bars, call for details)

FACE MACHINING OPTIONS - All of our line boring systems are available with face machining options available. Our largest facing head (which fits the BB6) will machine up to 24" (610mm) We offer a line of very compact face machining heads as well, for working in those tight spaces. (order # varies depending on model chosen) See example of our auto facer here

SNAP-RING GROOVE MACHINING KIT - This unique, patent pending tool offers you the simplest way to restore damaged or worn out snap ring grooves in your equipment bores. This kit will fit easily in bores that no other tool will fit into. A great compliment to your bore repair system. (order # varies depending on model chosen)

SURE-CUT SYSTEM - This oxygen lance is one slick, easy to use tool that should be on every service truck and in every shop that works on repairing worn out bores. Pays for itself in 1-2 uses in time savings. If you've ever had to deal with how to remove a stuck or frozen/rusted in pin you will appreciate this system. In minutes it can pierce a hole straight through the stuck pin. Once it cools a few minutes later, the pin shrinks and the rust bond is broken and the pin can be easily tapped out. This tool, when compared to using a press or a sledge hammer can potentially save hours of labor. (order #JRSC2024S-REG)

Low-Profile Bar Centering kit - This kit offers a handy way to get your boring bar centered when using cones is not a good option. For example when the bore faces are not square to the bores or the bores have lots of wear and are no longer close to round you will find that pre-centering your bar using this kit is much easier and accurate. These kits are available to fit 1.25", 1.75", 2.0" and 2.25" diameter bars. Kits include a pair of centering rings, weld-on centering tabs, centering screws with knurled ends and instructions.

SPECIALTY EQUIPMENT

L-34 LINEAR WELDING SYSTEM -This is a special welding device for use with a turntable which contains a part being rotated that requires a weld clad to be applied to either the internal bore or external round surface. The standard L-34 can reach 100" (250cm) into a bore or along the outside diameter of a part. It has a continuous stroke of 34" (860mm)  The L-34 system comes complete with a unique telescoping welding gun assembly with fully adjustable angle weld head, quick position feed arm and a trigger mechanism that works in conjunction with the turntable. Every revolution of the part triggers the L-34 to index the weld at a set, consistent amount. This is the easiest way to quickly clad ID's and OD's that we have found. Case studies report some jobs that used to require days of hand welding to be reduced to mere hours using the L-34.

BOA-SIZER BORE FINISHING SYSTEM - When using a home made line boring system or other line bore system that utilizes traditional roller bearings, it can be very difficult to achieve the tight tolerances required for press-fits of new bushings. Unlike the unique tune-able bearings that Bore Repair line boring systems utilize which offer a means of adjusting the actual ID of the bearing so there is no excess play between the boring bar outside diameter (OD) and the bearing race internal diameter (ID), roller bearing style boring bars have a problem with excessive play between the boring bar and bearing...obviously if there is .005" clearance between the boring bar and bearing race, then it is very difficult to machine to a .001" tolerance.  Enter the BOA-Sizer. The BOA-Sizer tackles this common problem by honing the bore the final .005" to .010" to the desired final diameter while leaving a desirable class A finish. Bore Repair Systems, Inc. offers direct mount systems to use the BOA-Sizer on your off-brand line bore system, as well as universal mounts for customers wanting to use the sizer with a home-brew boring bar that utilizes roller bearings.
