A-220 2-Axis Micro-Bore Self-Centering Target for Bores from .75-1.5 in.

A-220 2-Axis Micro-Bore Self-Centering Target for Bores from .75-1.5 in.

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.
