T-218 2-Axis Reference Target

Hamar Laser’s T-218 2-Axis “See-through” target is designed for multiple-target, bore centering applications. A small mirror directs the beam to the target cell that is 90 degrees to the centerline. The mirror can be flipped out of the way to allow the laser beam to pass through the target body without optical interference. The T-218T Turbine Target  has an adapter flange for turbine alignment applications and works much the same as reference targets. The target fixture (A-502A) is swept into the center of the bore using the A-501(A) sweep unit, then the target is placed in the fixture and the reading is taken.

  • Bar feeders
  • Cam/Crankshaft/Cylinder Bore Alignment/Inspection
  • General alignment of large bores
  • Lathe steady-rests
  • Turbine bores
  • 10×10 mm PSD (position sensing device). (Note: For a large-range see-through target, see the T-1220 datasheet).
