Adjusting parallelism (1)

(Adjusting the connecting rod)

1. Loosen bolt A (2 each) of the X and Y

stoppers to disengage the stoppers.

2. Loosen the rod end and nut of the

connecting rod and set at the 210q and 90q

position (X/Y direction) on the digital

sequencer timer.

3. Tighten the rod end and nut of the

connecting rod.

=CHECK=

This adjustment is required only when

exchanging the rod end and the

connecting rod.

To adjust the parallelism only, skip

these steps.

Adjusting parallelism (2)

(Fine adjustment of the XY axis)

1. Set the digital sequence timer to 210q using

the hand wheel.

2. Loosen the adjusting bolt fixing bolt (2 − M6)

slightly.

3. Using the adjusting bolt, adjust the X−Y axis

so that the swing achieves right angle (90q).

(It is not necessary to input the exact value.

Set to right angle visually.)

4. Retighten the adjusting bolt fixing bolt (2 −

M6).

5. Loosen the M6 bolts (x 3) of the stage (2)

and adjust so that the X axis swing may be

(Fine−adjust so that the parallelism may be

within 0.04 mm while lightly tapping the

stage (2) with the copper rod.

6. Retighten the M6 (x 3) bolts.

7. Set the digital sequence timer to 90q using

the hand wheel.

(Ensure that the accuracy in Y direction is

within 0.04 mm.)

=REFERENCE=

If the above−mentioned accuracy

cannot be obtained, repeat steps 1

through 7.

Adjusting parallelism (3)

(Adjusting the X stopper)

1. Using the hand wheel, set the digital

sequence timer to 210q.

2. Press the X stopper against the stage (1)

and secure it with bolts.

=REFERENCE=

Too strong pressing the stopper will

cause the low accuracy.

3. Check that the accuracy is within 0.04 mm

again.

Adjusting parallelism (4)

(Adjusting the Y stopper)

1. Using the hand wheel, set the digital

sequence timer to 90q.

2. Press the Y stopper against the stage (1)

and secure it with bolts.

=REFERENCE=

Too strong pressing the stopper will

cause the low accuracy.

3. Check that the accuracy is within 0.04 mm

again.

x Lever−operated dial gauge

Required tools

Parallelism check

1. Remove the spring from the insertion

head.

2. Set the machine to manual mode and turn

OFF the HEAD SWIVEL LOCK. Turn the

hand wheel until the cam shaft is at the 0q

position on the digital sequence timer.

3. Attach the lever−operated dial gauge to

the guide rail (fixed side) on the X−Y

table.

4. Set the measuring needle on the side

surface of the insertion head.

5. Move the X−Y table in the X direction by

hand.

=CHECK=

If sliding the X− Y table by hand, make

sure the table does not slip in the Y

direction.

6. Check parallelism of the insertion head

(inserting chuck) against the guide rail is

between 0.05/20 − 30 mm.
