The A-514 A, B and C Self-Centering Laser and Bore Adapters
The A-514 self-centering laser and bore adapters
accurately and quickly position the laser and target on the
bore centerline. The adapters can be centered to the bore
to within .0005 in. (0.0127 mm). The adapters have
adjustable legs that allow them to be used for bore
diameters ranging from 3.5 in. (90 mm) to 40 in. (1m) and
the A-514B and A-514C come with counterweights to
prevent the assembled system from tipping. Three sizes
are available, as follows:
•
A-514A
for bores from 3.75 in. (95 mm) to 6.75 in.
(172 mm)
•
A-514B
for bores from 6.5 in. (165 mm) to 17.5 in.
(445 mm)
•
A-514C for bores from 17.0 in. (432 mm) to 40.0 in.
(1 m)
Note: For bores over 1 m, half-bores, or where bore
surfaces are worn or rough, the T-218 Two-Axis
Universal Target and T-225L Large Bore Flange are used. The T-218 has a prism that flips out of the
way, allowing the laser beam to pass unobstructed through the target without removing it, which proves
useful for aligning multiple bores over long distances. For half-bores, the T-218 is used with the A-502A
Half-Bore and A-501A Bore Sweep Fixtures.
