Existing methods for measuring the straightness of cylinders, such as optical borescopes or tight wire, are time consuming. It is also very challenging to get good repeatability from operator to operator with these methods, especially in long cylinders.

In some cases, it is nearly impossible to use these methods for smaller diameter bores. We offer a better way.

L-703B Self-Centering Bore Alignment System

Our 50 years of alignment experience went into the design of the L-703B Self-Centering Bore Alignment System that makes aligning engine blocks easier and faster:

  • Newly designed, the L-703B Laser is smaller and lighter than previous models.
  • Also newly designed L-103 Laser Beam Translator and L-112 Laser Stand, which has built-in position control, helps to speed up the laser buckin.
  • Easy-to-use, patented self-centering targets that only require 1 measurement per bore — no 0° and 180° measurements!
  • Setup in as little as 15 minutes; bore alignment data can often be analyzed in 30 minutes or less.
  • Our self-centering targets can easily measure bore diameters from 1.18 to 40 in. (30 to 1,000 mm).
  • Resolution of .00004 in. (0.001 mm) and bore alignment/concentricity accuracy up to .0002 in. (0.005 mm) per 10 feet (3 m).
  • Simple X-Y readouts require very little training, making it the easiest system on the market to learn and use.
  • L-703B runs on a lithium-ion, rechargeable battery with 11 hours of continuous battery life.
  • Optional Windows-based Bore9 Software records data, analyzes the results and produces reports.
