8. Applications

8.2.3 Altering the feeds or thread pitches

for D2000 and D2400

When altering the feeds or thread pitches, proceed as follows:

1. Changing the feed from 0.085 mm to 0.16 mm

a. Loosen fixing screw D of the change gear quadrant.

b. Loosen and remove the hexagon nuts and washers from the bolts A and B.

c. Loosen the hexagon bolts A and B. Remove the toothed belt connecting A and B. Unscrew

bolt B together with the two tooth belt pulleys from the quadrant and remove it by slightly

tilting the bolt upwards (this at the same time leaves free the toothed belt from B to C).

Remove the toothed belt connecting the main spindle with A by placing the toothed belt onto

driving pulley E.

d. Remove both tooth belt pulleys Z 14 from bolts A and B and replace them by toothed belt

pulley Z 18 or toothed belt pulley Z 20, respectively. Mount and tighten the washers and nuts

to A and B.

e. Mount bolt B together with both tooth belt pulleys to 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. Put on toothed belt from main spindle to bolt A and from bolt A to

bolt B.

f. Pull bolt A upwards until the toothed belt is strained, then tighten bolt A. Strain the belt

between main spindle and bolt A by means of the change gear quadrant and tighten the

quadrant with screw D.

g. Close the cover and re-tighten the hexagon socket screw.
