5.1 XY Table Positioner and Guide Rail Check and

Adjustment

DA3SEC−83−8H0−A0

Sentence No.

When to perform

x After replacing the positioner

x When too much correction from the PC

board center towards the outside is

required while performing teaching (PC

board is tilted with respect to the X−Y

table).

x Micrometer

x Slotted screwdriver

x Lever−operated dial gauge

x Plastic tip hammerSteel rule

x Steel rule

Required tools

Positioner pin and shaft check

1. Loosen the lock screw and remove the pin

from the positioner lever. With the

micrometer, measure the diameter of the

pin. Here, check diameter is correct.

=REFERENCE=

If the positioner pin is too tight to be

removed, remove the entire lever and then

remove the pin with an pin extractor.

2. With the pin extracted, slide a PC board along

the rails checking to make sure it slides without

catching or incurring other irregularity.

3. Widen the distance between the X−Y table

guide rails to the with required for the largest

PC board. Attach the lever−operated dial gauge

to the upper frame and set the measuring

needle so that it contacts the shaft side of the

positioner. Slide the X−Y table in the X direction

checking shaft parallelism against the frame is

within 0.03 mm.

=REFERENCE=

If sliding the X− Y table by hand, make sure

the table does not slip in the Y direction.

Positioner lever height check

1. With the steel rule or other scale, check the

height of the guide rail where it contacts the PC

board, and the height of the top surface of the

positioner lever are the same.

Positioner shaft straightness

check

1. Press the steel rule flat against the shaft

checking the shaft is not bent anywhere.

Measuring positioner pin

parallelism to the X−axis

1. Attach the dial gauge at the top of the base

plate on the head side.

2. Set the measuring needle on the side

surface of the positioner pin (reference

side). Bring the scale reading to “0”

(reference point).

=REFERENCE=

Set the measuring needle on the

positioner pin as shown left.

3. Slide the X−Y table in the X direction by

hand making sure that the measuring

needle contacts the side surface of the

positioner pin (moving side) and checking

parallelism is within 0.03 mm.
