Description
Hamar Laser’s A-220 Micro-Bore, Self- Centering Target is designed specifically to measure the straightness of small bores, from .70 in, (18 mm) to 1.5 in, (38 mm). This small, lightweight, compact target self-centers to an accuracy of .0005 in. (0.013 mm) and has a sensor area of 4 x 4 mm. It requires the L-706SM Small-Beam Bore Laser. It works with the following customized bore adapters:
- M-220-ID-SC-BL – this is a set of 2 self-centering bore adapter discs customized to a specific bore ID. Specify bore ID and bore (barrel) length for insertion pole.
- M-220-ID-BW-BL – this is a set of barrel-wear bore adapter discs customized to a specific bore ID. Specify bore ID and bore (barrel) length for insertion pole.
Applications
- Large-caliber gun-barrel straightness
- Small, short bore concentricity/alignment
- Small-bore twin-barrel extruders
- Tube-sheet bore straightness
Features
- Up to 6 ft. (2 m) carbon fiber insertion pole with connector. Extra lengths of pole are available for bores up to 10 feet (3m) long.
- Uses M-220-ID-BW-BL or M-220-ID-SC-BL customized bore adapters. The adapters are customized for each bore ID, but can accommodate diameter changes of ± .010 in. (0.25 mm) without affecting the ability to self-center in the bore.
- 4 x 4 mm PSD (Position Sensing Detector) is concentric to bore ID to.0005 in. (0.013 mm).
- .00002 in. (0.0005 mm) resolution when used with the R-1307 Readout.
- .654 in. (16.6 mm) OD, with tungsten carbide, precision-ground measuring balls (feet) and a tapered end for easy insertion in bores.
- Accommodates bores from .70 in. (18 mm) to 1.5 in. (38mm).
- Can be used with the R-1307C or R-1307 2.4ZB target readouts.
- Use the A-910-2.4ZB Radio Receiver for a PC with the R-1307-2.4ZB for wireless data downloads to our Bore9 software.
- Spirit level orients the PSD sensor axes to the alignment axes of the bore.
