Bore ID Surface Measurement Alignment Fixture
Lasercheck can be equipped with our optional model YMC070016 bore ID measurement alignment fixture. This
mates and centers with a range of bore curvatures setting correct vertical and horizontal position of the head
ensuring accurate measurements.
The YMC070016 fixture on the 6212 measurement head can be used on any ID bore diameter 2 inches (50 mm)
or greater. This measurement capability is suited for large high quality bores like engine cylinder bores and
hydraulic shafts that have been honed to high surface quality.
Directional / Rotational
Many machined surfaces have a dominant direction of roughness. The length of the Lasercheck head must be
oriented perpendicular to the direction of roughness so that the scatter strikes the detectors, which are oriented
in a line down the middle of the head. Well-designed mounting hardware will ensure proper orientation.
If Lasercheck is not aligned at right angles to grinding groves on a directional ground surface for example (or
straight along the length of a cylindrical barrel) t
hen the “line” of scattered light will not perfectly fall on the
detectors in Lasercheck. Well-designed fixtures will ensure accurate measurements.
