"Positioning" refers to moving a moving body, such as a workpiece or tool (hereinafter,
generically called "workpiece") at a designated speed, and accurately stopping it at the
target position. The main application examples are shown below.

To punch insulation material or leather, etc.,
15m/min
(2000r/min)
as the same shape at a high yield, positioning
is carried out with the X axis and Y axis
15m/min
servos.
(1875r/min)
After positioning the table with the X axis
servo, the press head is positioned with the Y
axis servo, and is then punched with the
press.
When the material type or shape changes, the
QD75
AD75
press head die is changed, and the positioning
pattern is changed.
Using the servo for one axis, the palletizer is
positioned at a high accuracy.
The amount to lower the palletizer according to
the material thickness is saved.
QD75
The ATC tool magazine for a compact
machining center is positioned.
The relation of the magazine's current value
and target value is calculated, and positioning
is carried out with forward run or reverse run to
achieve the shortest access time.
