A new, high accuracy version of the Model 1200 Gage for measuring crank-shafts and camshafts is  introduced by Adcole Corp.

The ADCOLE Model 1200 crankshaft-camshaft gage features proprietary refinements to the spindle, including significant components and subsystems to achieve accuracies for roundness of better than a quarter micron (0.25µm) for measuring pin journals.  This exceeds the 10% rule of the new 2.5 micron roundness tolerance now being introduced by engine manufacturers, according to the company's press release.

 Capable of measuring pin journal roundness, cylindricity, straightness, parallelism, diameter, taper, radial runout, concentricity, and other critical parameters, the ADCOLE Model 1200 crankshaft-camshaft gage incorporates a laser interferometer measurement system and is built on a base of structural steel. Applications include machine tool performance verification, manufacturing process control, and final parts inspection.
