Cleaning/lubricating the W-axis and U-axis
The once-a-year cleaning and lubricating for ball screw, guide, and hexagon spline of W-axis and U-axis is
required. See also "Chapter 4 Lubricating points" for details.
1
Read any board data.
TIP
Moving the push up unit of both stage 1 and stage 2 are
available by reading board data.
2
Set the conveyor width to the minimum.
1. Press the [Width] button on the [Unit] -
[Conveyor] screen to display the [Conveyor
width] screen.
2. Input the minimum width of "50mm" in the
"Target width" field and press the [OK]
button. Then the conveyor width is changed
to the specified.
3
Raise the push up unit.
1. Press the [Push up] button to display the
"Conveyor Pushup" screen.
2. Input "0.1 mm" in the "Board thickness" field
and press the [OK] button. Then the push up
unit raises.
3. Raise the push up units of both stage 1 and
stage 2 by the procedure above.

NOTE
When the board size X of the board data selected at Step
1 excesses 380mm, the [Push up] button of upstream side
is grayed-out. The upstream push up unit raises engaging
with the raise of downstream push up unit.
n
NOTE
The access to the guide and ball screw of U-axis become
easier by raising the push up units.

Clean each section of W-axis and U-axis.
1. Press the emergency stop button and detach
the feeder exchange carriage. Then open
the machine safety cover.
2. Remove all items sensitive to magnetic fields
such as wristwatches and magnetic ID cards.
3. Wipe away old grease or dirt from all over
the 8 ball screws, 6 guides, and 4 hexagon
spline of W-axis and U-axis, using a lint-free
cloth or similar.
n
NOTE
Carefully wipe the lead grooves of ball screw and the
grooves of guide rail during cleaning. Also, make sure
that no dust, lint and debris remain on the ball screw and
guide.
n
NOTE
See also "Chapter 4 Lubricating points" for the positions
and numbers of ball screw, guide, and hexagon spline.

Maximize the conveyor width.
1. Close the machine safety cover and attach
the feeder exchange carriage. Then release
the emergency stop.
2. Press the [Conveyor width] button to display
the [Conveyor width] screen.
3. Input the maximum width of "510mm" of the
dual stage type machine in the "Changed
conveyor width" field and press the [OK]
button. Then the conveyor width is changed
to the specified.
TIP
The push up unit lowers automatically by changing the
conveyor width.
