T-220 2-Axis Small Bore Self-Centering Target

T-220 2-Axis Small Bore Self-Centering Target

Descriptions

Self-centering bore target for measuring the straightness of long, small-ID bores, such as gun barrels and other similar cylinders. Each target is customized to the nominal bore ID and comes with a self-centering adapter, insertion pole and cable. Can be used on bore diameters from .70” (17.8 mm) to 1.5” (37.6 mm). Requires a modified L-705 or L-706 Bore Laser with a small-diameter beam.

APPLICATIONS

  • Tube sheet bore straightness
  • Large gun barrel straightness
  • Small extruder barrel alignment

FEATURES

  • Straightness checks on cylinder or gun-barrels up to 4.5 feet (1.5 meters) long.
  • 0.001 mm resolution and < 1% linearity and a PSD size of 4x4 mm.
  • PSD centered to measuring feet to within .0005” (0.012 mm)
  • Hollow carbon fiber insertion pole to allow the cable to connect to the readout.
  • Used with R-1307 Readouts.
  • For bores from .70” (17.8 mm) to 1.5” (37.6 mm).
  • Requires a modified L-705 or L-706 Bore Laser with a small-diameter beam.
