Feeder carriage position

adjustment

1. Loosen the installation bolt (x 4) fixing the

feeder carriage holder in place. Adjust the

holder to the left and right until feed position is

correct (V−cut shape).

=REFERENCE=

Adjust so that the holders at the right and

left ends are parallel to one another.

Ex. If the lead of the Z axis No. 1 has a

V−cut shape but that of No. 60 doesn’t,

loosen the installation bolt fixing the

holder on the Z60 side and adjust it

conforming to No. 1 as the reference.

2. After adjusting, adjust the feeder

to make sure

the feed pitch and the feeder carriage position.

Adjusting feed pitch (Cam feed

adjustment)

1. Set the parts cassette to the Z axis No. 1.

=REFERENCE=

Use a 5.0 mm parts cassette when

making adjustment.

2. Turn ON the FEED LOCK RELEASE on the

sub−control panel.

3. Turn the hand wheel to set the digital

feed slide and pusher shaft is 1.1r0.1 mm using a

thickness gauge when it stops.

=REFERENCE=

The parts cassette has two types; new and old.

Factory−equipped cassettes are the new type.

Clearance of the old type cassettes shall be

0.6r0.1 mm.

5. If the correct clearance cannot be obtained, loosen

the bolts to disengage the pusher shaft.

6. Move the pusher shaft to−and−fro to adjust the

clearance.

7. After adjusting, retighten the bolts and secure the

pusher shaft.

3. Remove the spring of the feed pusher from

the shaft and then the spring from the end of

the pusher. (Any spring of the two can be

removed first.)

4. Attach a new spring not to have a gap

between the pusher and shaft.

Be sure to attach the spring without any

gap to prevent the clearance to be

changed in feeding the parts cassette.
