Our 406 Series Bore Targets may be used to establish centerlines of
large cylindrical units or bores such as extruder tubes, crankshaft bores,
turbine/ generator bores, etc. The compact and flexible design
accommodates a wide range of bore diameters.
Two models are available in this
series: the model 406-6 accommodates a maximum
bore diameter of 60" (1.52m), while the 406-6A can
handle a bore up to 150" (3.8m) in diameter.
The unit is made for quick and easy field setup. Stability is
assured with solid leg connections (rather than telescoping legs) and the
use of "sleds" as feet - no more targets slipping or falling
out of bores during your alignment. This feature makes
the 406 Series ideal for half-bore and vertical applications.
Leg design helps to minimize sag.
 In use, the target is first positioned
roughly in the bore center with adjustable feet, then the
central target holder is "indicated in". This is
achieved using the dial indicator, which is mounted on a
sweep arm connected to a rotating central hub. The hub, in turn, contains the
optical target. The central hub is adjustable so that it
- and therefore the target - may be brought to dead center.
This process also reveals and quantifies any out-of-round
conditions in the bore.
When used in half-bore configurations, the horizontal legs are situated just
below the bore's centerline (photo at right).
The target holder is sized for any 2¼" diameter target. The kit
includes a 795 multi-shot distance
target. The legs terminate in ball feet or sleds, as desired by the
user (both are included). The target
holder also has unique adjustments for calibration of wire
targets.
At left, the 406-6 is shown in small bore configuration. The
indicator initially mounts in the target holder. After the central hub is brought to
the center of the bore, the indicator is removed and replaced
with the optical target.
At left below, the 406-6 bore target kit comes complete in a
polyurethane case with foam inserts. Each 406 Series
Bore Target Kit contains the components shown at right below
(see table below for component listing).
