Altering the feeds or thread pitches for D2000 and D2400
2.
Changing the feed from 0.085 mm to a metric pitch of 1.5 mm
a. - c. Start the procedure exactly as already described under pos. 1, a-c, with the exception that
the hexagon nut must be removed from the quadrant bushing C, too, as additional step of the
procedure described under pos. 1 b.
d.
Pull the bushing and the tooth belt pulley Z 48 off the quadrant bushing C. Put the bushing
and the tooth belt pulley Z 24 onto the quadrant bushing C, but make sure that the bushing
precedes
the tooth belt pulley.
Bolt B with toothed belt is not needed for thread cutting!
e.
Pull off tooth belt pulley Z 14 from bolt A and put on tooth belt pulley Z 36. Put on the toothed
belt from the main spindle to bolt A as well as the belt between A and C.
f. - g. Proceed as described under pos. 1, f-g!
i
Only the two short toothed belts (1145) are required for cutting metric threads as well
as the slightely longer toothed belt (1146), which connects the main spindle with
wheel A. The toothed belt (1145) connects wheel B with wheel C.
3.
Changing the feed from 0.085 mm to thread pitch 12 threads/"
Proceed exactly as already described under pos. 2. The procedure differs merely in
additionally replacing the tooth belt pulley Z 48 running on bolt A by the tooth belt pulley Z 34.
bolt B escape
to change Z 48 against Z 34
i
As when cutting metric threads, in most cases only the two shorter toothed belts
(1145) are required. Exception: For a lead of 13. 14. 16 or 19 threads/inch. In this
case, the longer toothed belt (1146) is required to connect wheels A and C.
