  • Page 46 b. Place the A-703SP-LM on top of the straightedge, aligning the channel (cutout) on the bottom to the straightedge, making sure to put pressure on the straight edge to prevent it from sliding. Then, holding down the straightedge, slide the laser fixture against the straightedge to make it parallel to the straightedge and line segment.
  • Page 47 Step 5a – Place T-1297 Target & Base on the Plate Place the T-1297 Target and Base on the plate near the laser, gently push it against the straightedge, and line up the Measuring Plane of the base with the zero point on the scale (see image).

Then click Record to record the first data point. When positioning the target, line up the Measuring Plane (front edge of target base mounting surface) with the ruler dimension before hitting Record.
  • Page 49 However, DO NOT TOUCH THE L-703SP- laser fixture since it does not have rubber feet and can be moved easily. Moving the fixture can cause the laser beam to move, causing measurement errors.
  • Page 50 Note - you do not need to re-adjust the laser beam since you are using the same straightedge, which means the alignment of the laser to the straightedge should hold its position, so after positioning it and the L-703SP-LM, you can start recording.
  • Page 51 Step 2. Also pay attention to which end of the line to put the L-703SP-LM Laser Fixture. For line GE, it will be the right side of the line – see below. Find the straightedge that best matches the length of that side of the plate.

  • Page 56: L-703Sp - How It Works - Step 2 - Line View

    One of the annoying parts of using electronic levels when re-surfacing a surface plate is you have to shoot the entire plate for flatness to see how the lapping process is going. This is a waste of time! With the L-703SP Surface Plate Calibration Systems, you can do quick checks of a single line segment in about 3-5 minutes to see how much the flatness error has been reduced.
  • Page 57 Use the corner/midpoint locating tool to set up the straightedge as shown above on pages 35, 41 or 42. Then, place the L-703SP-LM Laser Fixture on the straightedge, as shown above. Step 4 - Set Up Laser Line Before taking data, it’s a good idea to make sure the laser is still reasonably parallel to the A- 703SP-LM Laser Mount.
  • Page 58 Step 5 - Move Target to Far Point and Adjust Laser’s Pitch/Yaw Move T-1297/A-1297-SP Base to the far end of the straightedge. Adjust the Pitch and Yaw knobs on the laser until you get to around 2,000 µin (50 µm) for the V axis and 5,000 µin (125 µm) for the H axis.
