Altering the feeds or thread pitches for D2000 E and D2400 E
When altering the feeds or thread pitches, proceed as follows:
1.
Changing the feed from 0,085 mm to 0,16 mm
a.
Loosen the fixing screw D of the change gear quadrant.
b.
Loosen and remove the hexagonal nuts and washers from the bolts A and B.
c.
Loosen the hexagonal bolts A and B. Remove the toothed belt connecting A and B. Unscrew
the bolt B together with the 2 tooth belt pulleys from the quadrant and remove it by slightly
tilting upwards the bolt. This at the same time leaves free the toothed belt connecting the
main spindle with A by placing the toothed belt onto the great driving pulley E.
d.
Remove both tooth belt pulleys Z 14 from their bolts A and B and change them for tooth belt
pulley Z 18 or tooth belt pulley Z 20, respectively. Then, tighten bolt A. Mount and tighten the
washers and nuts of A and B.
e.
Mount bolt B, together with both tooth belt pulleys into the change gear quadrant again by
slightly tilting the bolt and screwing it into the square nut located behind the quadrant. Put on
the toothed belt connecting B and C, pull bolt B upwards imparting tension to the toothed
belt. Then, tighten bolt B.
f.
Put on toothed belt from main spindle to bolt A and from bolt A to bolt B. Then tense the belt
between main spindle and bolt A by means of the change gear quadrant and tighten the
change gear quadrant with fixing screw D.
g.
