10.2.4 Changing of feeds or thread pitch for D3000 E
1. Working with the automatic longitudinal feed
a. Turn the handle (19) on the symbol longitudinal turning. For the connection of the clutch disk
turn with with the handle (31212) a little.
b. Switch-on the direction switch on the right of the substructure.
middle position = off
left injected = advance to the spindle
right injected = advance to the tailstock
With the potentiometer adjust the feed speed.
c. After the automatic longitudinal turning but the direction switch on the middle position.
2. Working with the thread cutting unit
a At first for the desired thread pitch the changing wheels must be mounted. Your receive the
machine from our factory with yet mounted wheels Z 36 and Z 24 for a thread pitch of 1,5 mm.
During putting of metric threads the toothed wheel Z 48 is placed on the change gear quadrant
as shown on the picture 6.22. During cutting of inch thread this wheel has to be replaced
through the tooth wheel Z 34.
For the different thread pitches only the tooth wheels B (beside Z 48) and C ( on the main
spindle) according to picture 6.22 have to been changed.
b. Select slowest spindle feed.
c. Turn the handle (19) on the symbol thread turning. The handle must be in function till the
thread is ready produced. For the cutting of several cuts to produce the thread the machine
must be stopped with the reversing switch at the end of the thread and at the same time the
threadcutting tool separated. Now turn the reversing switch on left turning and the carriage
runs in the direction of the tailstock. If the threadcutting tool is placed approx. 5 mm in front of
the beginning of the thread, stop again the machine, turn the cross-slide ahead like the before
made cut plus the desired removal of material. Then turn the reversing switch on right turning
and execute the cutting of the thread. Only when the thread is finished the handle (19) can be
put out again.
