3.8.1 (Part 1) Table Leveling
1. Loosen all of the XY table Pcb clamping claws with a 3mm wrench.
2. Loosen the sensor flag base and remove the sensor flag from the fixed rail. (Fig.11)
(CP-742/743(M)E)

3. With the cam angle at 0 degrees, release the air and set the gap between the reference and
adjustable rails at a position adequate for setting the dial gauge.
4. Reconnect the air and clamp the two rails.
5. (Initial Leveling) Level the table as illustrated below by loosening the four corner lock nuts
and adjust the table flatness (at the points indicated) to be within 0.1mm. After completion,
ensure the lock nuts are securely tightened. Then, apply Three Bond 1320N to the four lock
nut locations as indicated in Fig.12.

6. (Final leveling check) The reference point for measuring the table flatness is the far right claw on
the adjustable rail, when it is 50mm from the fixed rail (indicated by a 0 in Fig.13). Measure the rail
flatness at the nine points identified in Fig.13.
(Tolerance: +/- 0.15mm,)(within 0.1mm is best)

7. If the adjustable rail is not flat at the locations illustrated, it may be necessary to repeat step 5.
8. Once the adjustable rail flatness is within tolerance. Use the 0 position (Fig.14) as the reference to
check the height between the adjustable and reference rails at the hi-lighted positions.

9. If the height of the reference rail is more than +/-0.1mm than that of the adjustable rail, (or the
reference rail itself is uneven) adjust the reference rail height (flatness), by loosening the bolts
indicated in Fig. 15 and adjust, using the bolts under both sides of the reference rail.

3.8.2 (Part 2) Reference and Adjustable Rail Alignment in the Y direction
1. The two rails should be aligned to within 0.1mm. (with the adjustable rail at the center of
play)
2. Disconnect the air pressure to the machine and move the adjustable rail left and right to
establish the center of play using a dial gauge.
3. Reattach the air with the adjustable rail at the center of play.
4. Align the reference rail to the adjustable rail (center of play) by loosening the bolts indicated
in Fig.16.

3.8.3 (Part 3) Origin Pin To Claw Position Adjustment (CP-742/743(M)E)
1. The distance from the origin pin to the claw should be between 3500 and 3600 pulses.
2. Install the origin pin and spring.

3. Using a dial gauge, set the distance from the pin to the claw, by moving the reference rail in
the Y direction. (set the distance as close to 3510 pulses as possible)
Note: The CP-732/733E does not have tooling pins, so steps 1 to 3 do not apply. The
rail is just centered in the bolt holes.
