This user guide will help thin section technicians prepare slide for bonding to billets. For more information refer to the Logitech Thin Rock Section Production manual, available both on a Logitech thumb drive in the Thin Section Lab cabinet and Thin Section Lab computer under the "Manual" folder on the desktop. Or, refer to Operation and Maintenance of the LP50 Lapping and Polishing Machine manual, located in the black binder in the Thin Section Lab cabinet labeled "LP50, PM5 and Associated Equipment".

PROCEDURE

SETTING THE JIG

  1. Use the jig labeled "Frost".
  2. Clean jig and Logitech scale by wiping them with a kimwipe and isopropyl alcohol.
    1. Refer to the Logitech LP Set Up user guide for more information on scale use.
  3. Set the scale on the jig gently (Fig. 1) and wiggle the scale.
  4. The jig should be set to 1217 (just before the 17 is better).
    1. Use the middle gauge on the scale.
      1. The small dial (Fig. 1) on the bottom left side should read 12.
      2. The large face (Fig. 1) should read 17.
        1. If the jig is not set, put the Tommy bar into the holes on the main post in the middle of the jig to adjust it (Fig. 1).
          1. Rotating the Tommy bar clockwise will lower the chuck face causing the numbers on the scale to increase.
          2. Rotating the Tommy bar counterclockwise will raise the chuck face, causing the numbers on the scale to decrease.

LAPPING UNFROSTED SLIDES

  1. Clean six unfrosted slides by washing them with hot water and wiping them off with a kimwipe and isopropyl alcohol. Then blow dry with the air gun.
    1. If slides are stuck together, let them soak in hot water. They should separate easily after a day.
  2. Set the clean slides on the jig's chuck face over the vacuum grooves. There should be no spaces between any of the sides (Fig. 2).
    1. If there are spaces the vacuum will not seal properly.


                                                  Figure 2


     3. Connect vacuum hose to the right forward vacuum plugin (Fig. 3).

4. Check oil level in the vacuum pump under the counter.

    1. If there is not a proper vacuum seal right away try pressing lightly on the slides to help them seal and make sure the exhaust flap (Fig. 4) is clean.
    2. If that does not work, take off the slides and clean them and chuck face again.

...

     9. The plate monitor can stay in place on the back arm (Fig. 5).

10. Turn on the abrasive drum by overriding and make sure it is dripping properly.

...

19. Place jig chuck face up in the sink (Fig. 6).




                             Figure 6


20. Scrub the jig and slides gently with a soft brush to break the vacuum seal.

...

22. Clean the jig by scrubbing it down with warm water and a soft brush. Then blow through the jig and on the chuck face with the air gun.

MEASURING FROSTED SLIDES

  1. Hold the micrometer with your pinkie and ring finger through the "C" part of the micrometer. Your index finger and thumb will move the dial (Fig. 7).



                Figure 7


2. Clean the micrometer before use by placing a piece of paper in between the two bars and closing it gently (do not apply force). Pull the paper out and repeat.

...

3. Place the slide in between the two bars and close them gently onto the slide (Fig. 8).



                 Figure 8
(This slide is "16")

    1. Take a measurement at the middle and sides to make sure that the frosted slide is even all the way across.
    2. Uneven slides will cause your sample to be uneven. If this happens put the slide back onto the jig and lap it down longer until it is even.

4. Organize the frosted slides into groups based on slide thickness (Fig. 9).
