  • Hamar Laser Introduces A-221 Small-Bore Self-Centering Target

    Ideal for extruder barrel alignment and large-caliber gun barrel straightness

    A-221 2-Axis Small-Bore, Self-Centering Target for Bores from 1.18-10 in. (30-255 mm)

    Hamar Laser is pleased to introduce a new small-bore target. The A-221 Self-Centering, Small-Bore Target is designed specifically to measure the straightness and alignment of small- to medium-size bores, from 1.18 in. (30 mm) to 10 in. (255 mm). This makes the A-221 Target an ideal alignment tool for large-caliber gun barrel straightness, cylinder straightness and small single- and twin-barrel extruder alignment applications.

    The small, lightweight, compact A-221 Target self-centers to an accuracy of .0007 in. (0.018 mm) and has a sensor area of 10×10 mm. The new target features self-centering bore adapters with customized legs to fit the bore diameter, but which can accommodate diameter changes of ±.040 in. (1 mm) without affecting the self-centering feature. The target’s 10×10 mm PSD (Position Sensing Detector) is concentric to target OD to within .0005 in. (0.013 mm).

    Other features include:

    • Measurement resolution of .0001 in. (0.001 mm) when used with Hamar Laser’s
      R-1307 Readout.
    • 5 ft. (1.5 m) insertion pole with connector for extra lengths up to a total of 15 ft. (4.5 m) insertion length.
    • Accommodates bores from 1.18 in. (30 mm) to 10 in. (255 mm) when used with customized Bore Adapters.
