L-741 Ultra-Precision Leveling and Plumb Laser

L-741 Ultra-precision Leveling Laser with Plumb Beam

Descriptions

Designed primarily for high-accuracy flatness and plumb (squareness) measurements, the L-741 Ultra-Precision Leveling Laser has 1 horizontal, auto-rotating laser plane that is flat 0.5 arc seconds (.00003 in/ft or 0.0025 mm/m) in a 360º sweep and 0.25 arc second in a 90º sweep. It also features a plumb laser beam that is perpendicular to the scan plane to 1 arc second (.00006 in/ft or 0.005 mm/m) and 3-arc-second illuminated level vials.

The laser is mounted on an adjustable base with coarse and fine pitch and roll adjustments, so that the laser plane can project the measurement reference out to 100 feet (30.5 m) in radius in all directions. The laser is completely self-contained and can operate on battery or AC power.

APPLICATIONS

  • Measuring and aligning:
    • The flatness and straightness of almost any horizontal surface up to 100 feet (30.5 m) (squares, frames, ways, flanges, circles, etc.)
    • The flatness and straightness of horizontal surfaces
    • The straightness of horizontally traversing axes of machine tools
    • The squareness of vertical to horizontal surfaces, up to 100 feet (30.5 m)
    • The parallelism of horizontal surfaces
    • Checking machine tool guideway twist in horizontal axes, machine beds and parallelism between horizontal guideways
    • Measuring surfaces up to 200 feet (61 meters) long with 1 setup
  • Machining centers, gantries and lathe beds.
  • Bore flanges squareness to bore centerline L-706 Bore Alignment targets and accessories.
  • Parallelism of 2 bores using the L-706 Bore Alignment targets and accessories.

FEATURES
