Our 50 years of alignment experience went into the design of the L-706 Self-Centering Gun Barrel Bore Alignment System that makes checking the straightness of long cylinders, such as gun barrels, much easier and much faster:

• Self-centering targets that require only 1 measurement per bore for bore diameters from 1.18 to 40 in. (30 to 1,000 mm).
• The system is designed to work with long insertion poles to easily position targets deep inside bores up to 20 ft (6.1 m) in length.
• For cylinders longer than 20 ft (6.1 m), we offer a unique method using roller bearings for the measuring feet to easily slide the target into the bore.
• Measurement resolution of .00002 in. (0.0005 mm) and accuracy to +/-.0001 in. in 10 ft (+/-0.0025 mm in 3 m).
• Set up in as little as 15 minutes; bore alignment data can often be recorded and analyzed in 30 minutes or less.
• Insert the L-700 laser into the machine’s chuck and check the alignment of the barrel while it is still on the machine.
• Uses simple X-Y readouts that do not require software, making it the easiest system on the market to learn and use.
• Optional Windows-based Bore9 Software for recording data, analyzing data and producing reports.
