  • Page 4: Critical Note On Calibration

    Critical Note on Calibration When configuring the R-1307 Readout, it is critical to match the target ID with the target ID identified on the serial number of the target. For example, if the target ID on the target serial number label is 2, then the R-1307 must also be set to the number 2. If the target and readout and not matched, a centering error of up to .002 in.

    Designed for high-accuracy bore alignments, the L-705/L-706 Laser Bore Alignment System offers the most accurate, yet easy to use laser alignment systems. With high resolution, capability to measure a wide range of bore diameters, and our patented self-centering bore adapters, this is the best bore alignment system on the market.

    Put the cover back on and secure it to the battery pack with the screws. Pulse/Continuous Modes (L-705 and L-706 Lasers) The L-705 and L-706 Lasers are now equipped with a PULSE/CONTinuous switch, which manually switches the laser beam between Pulsed and Fixed Beam Modes. Pulse Mode automatically removes the effects of excess (ambient) background light for the R-1307 readouts, providing a more accurate reading.

The fine-adjustment micrometers can steer the laser beam in the horizontal and vertical axes to .001 in. (0.03 mm) in 110 ft. (33 m). It can either be mounted in customer-supplied fixturing or used with our L-111 Laser Stand and L-102 Laser Beam Translator to be mounted outside the bore.

Place the T-218/T-225L Target in the Near Bore in the NORMal position (see Figure 15). 2. Insert the laser into the L-111 Stand with the level on the top, centered from left to right (see Figure 16).

    Bore Alignment Using the A-512 Target/A-514 Bore Adapter To perform alignments, the laser is mounted in the L-111 Laser Stand and the L-102 Laser Beam Translator is attached. The L-111 has coarse angular adjustment capabilities and the L-102 can translate (move) the laser beam up/down and left/right without changing the angle.

  • Page 29: Bore Alignment Using The L-111/L-102 And A-512/A-514

    Bore Alignment Using the L-111/L-102 and A-512/A-514 Two Point Buck-In Procedure Step 1: Insert the Target in the Near Bore Measure the nominal bore ID. Use the A- 514G Leg-Setting Gage to set the legs of the A-514 Bore Adapter to the nominal bore ID (see Page 10 for a detailed procedure on how to set the legs).
  • Page 30 Step 4: Laser Rough-in -- Position the laser until it is on target at the Near Bore Loosen the thumb screws on the L-111 stand and slide the assembly up or down until the laser beam is visually near the center of the target (you do not need the R-1307 for this). Tighten the thumb screws. Note: To aid in seeing the laser, tape a small piece of paper over the target window and trace an outline of the target opening.
  • Page 31 Step 8: Move the Target Back to the Near Bore Remove the target from the Far reference bore and reinsert it into the Near Bore. Be sure to place the target in the exact location that it was in previously, with the cable at 6 o’clock.
  • Page 32 Step 9: Translate the Laser to .0000 in. in the Near Bore Using the fine adjustments on the L-102 beam translator, adjust the laser beam until the readout displays .0000 in.

  • Page 33 Step 11: Move the Target Back to the Near Bore Remove the target from the Far Bore and reinsert it into the Near Bore. If the readout doesn’t display .0000 in. both vertically and horizontally, repeat Steps 9 and 10 until the readout displays .0000 in. vertically and horizontally in the near and Far Bore.

    Bore Alignment Using the L-111/ L-102/Bore9 Note: A visual buck-in (determining visually that the laser beam is near the center of the target without using the readout or the beam translator) should be done before attempting to buck-in using the readout and beam translator.
  • Page 35 Step 2: Target Mounting Error a. Insert the A-512 into the A-514 Adapter and insert them into the Near Bore, making sure the adapter's level vial is level. Then adjust the L-102 to zero the display and center the laser into the first reference bore (the graphic below shows how the L-102 moves the height of the laser beam, but not the angle).
  • Page 36 Step 3: Laser Buck-in a. Follow the on-screen instructions to enter distances from the laser to the Near Bore (D1) and from the Near Bore to the Far Bore (D2). Insert the target into the Near Bore and re-adjust the L- 102 to zero the display and center the laser into the bore.
  • Page 37 c. With buck-in offsets applied in the Bore9 software, steer the laser using the Pitch and Yaw knobs (angular adjustment) on the L-706 until the H and V displays are zero. d. Repeat the process to confirm zero at both end bores. The laser is now “bucked in” (concentric) to the centerline of the near and far reference bores.

  • Page 41 The readout always shows the displacement between the Target Center and the Laser Beam Center. When the Target Center is not on the True Bore Center, the numbers and the signs on the readout will change when the target is rotated because the Target Center is moved to a different location in relationship to the laser beam.

  • Page 42: Appendix B - Calculating Bore Diameters

    Appendix B – Calculating Bore Diameters Once the measurements have all been taken, a few simple calculations will provide detailed information on the internal diameter of the bore. Due to the design of the target and the NORMIN procedure, it is necessary only to know the reference diameter in order to calculate bore size at each measured point.
  • Page 43 Plotting Measured Data The following chart and calculations are provided to help record, calculate, and plot bore diameter data. The chart can be expanded to record as many measurement points as are required. Formulas for calculating offsets and diameter are provided, as well as a sample plot of readout data (see Figure 25 on Page 41).

  • Page 45: Appendix C - Remote Buck-In

    Appendix C – Remote Buck-in As the distance between the laser and the near target increases with respect to the distance between the two targets, bucking-in by the close method becomes nearly impossible. A special remote procedure has been developed for these situations. The remote buck-in uses simple geometry to make the laser beam parallel to the centerline of the two targets, and then centers the beam on that line.
  • Page 46 If the calculated Set Point exceeds the linear range of the target, (for example, the A-1519 target has a range of 1.0 in. or 25 mm) the laser unit itself must be moved by the Set Point amount. New measurements must then be retaken for both targets, and a new set calculated. Figure 28 shows how to move the laser depending upon the sign of the calculated Set Point.

  • Page 49: Appendix F - Care And Cleaning Of Target Optics

    Appendix F – Care and Cleaning of Target Optics The proper care and cleaning of optical windows and/or lenses of Hamar Laser’s position-sensing devices (targets) assures optimum performance. Contaminants on an optical surface increase scatter, absorb laser energy, and eventually degrade the accuracy of the position-sensing devices. Because cleaning any precision optic risks damaging the surface, optics should only be cleaned when absolutely necessary.
