1. Loosen 2 each of the setscrews
and setscrews
.
2. Press the X feed stepping motor
in the direction of the arrow to
reduce the backlash to zero.
3. Tighten the setscrews
and setscrews
.
1. Remove 4 setscrews
and take out the Y feed stepping motor
.
2. Confirm that distance is kept 40.7 to 40.8mm between the tip of the Y
drive bevel gear
and the spigot joint of the Y feed stepping motor
.
If this distance is not secured, loosen 2 setscrews
to remove the Y
drive bevel gear
and adjust the number of teeth of the Y drive
bevel gear spacer
.
(The spacer thickness is 0.1mm. Usually, two pieces are used.)
(Caution) When tightening the setscrews
, try to join the flat
section of the shaft of the Y feed stepping motor
with
the position of the setscrew
. At that time, confirm that
the Y drive bevel gear
does not move in the axial
direction.
3. Install the Y feed stepping motor
on the bed.
4. Press the Y trailing gear
in the direction of the arrow to reduce the
backlash to zero and tighten 2 setscrews
. At that time, join the flat
section of the Y drive shaft
with the position of the setscrew
.
o If there is any backlash, needle
entry accuracy is lowered. This
can also be a cause of feed error.
o Too much pressing may result in
an increase in the feed load, thus
causing feed error.
