When Y-axis (vertical axis) performs automatic grinding,
if the total downfeed is over or equal to the setting value
shown on the display (43), then automatic downfeed will
stop. Once the setting times shown on the display (36)
reaches (Automatic zero return), Y-axis (vertical axis) will
perform automatic downfeed at cross and longitudinal
downfeed point.
When Y-axis (vertical axis) performs automatic grinding,
the spindle will automatically downfeed until the current
value shown on the display (33) reaches the setting value
shown on the display (40). Then the machine will perform
spark out grinding according to the times set on the
display (37). (Once times reaches, it will automatically
return to zero)
1. When the display shows "red X ", it means the spindle
head does not raise automatically.
2. When the column shows "red, concave" and "red X "
disappear, it means the spindle head raises
automatically.
1. When the display shows "no frame, convex", it means
cross feed is not locked.
2. When the display shows "red column, concave", it
means cross feed is locked. (In this case, the cross
feed motor can't run. When this occurs, check if the
CROSS LOCK KEY is pressed and Z. LOCK lamp
flashes or not).
When Y-axis (vertical axis) performs automatic grinding,
it provides target point setting value for workpiece to be
ground.
When Y-axis (vertical axis) performs automatic grinding,
the spindle will automatically downfeed until the current
value shown on the display (33) reaches the setting value
shown on the display (40). Then the machine will perform
spark out grinding according to the times set on the
display (37). Once times reaches, the control will
automatically judge if the key no. 38 should be set at
automatic raise or not. If setting at automatic raise
condition, the spindle will automatically raise to the
position set by the raising point value.
When Y-axis (vertical axis) performs automatic grinding,
the spindle will automatically downfeed. Before the
current value shown on the display (33) reaches the
setting value shown on the display (40), an allowance will
be left for final finish grinding. The setting value is the
allowance setting value for final finish grinding before the
current value on the display (33) reaches the setting
value on the display (40).
When Y-axis (vertical axis) performs automatic grinding,
you can properly set the intermittent spark out grinding
amount, so that when the total downfeed is over or equal
to the setting value shown on the display, then automatic
dewnfeed will stop. Once the setting times shown on the
display (36) reaches (Automatic zero return), Y-axis
(Vertical axis) will perform automatic downfeed at cross
and longitudinal downfeed point.
