• To punch an insulating material or
15 m/min
leather with a single die, positioning is
(2000 rev/min)
performed using two servo motors.
One servo motor is for feeding (X-axis)
15 m/min
(1875 rev/min)
and second servo motor is for press
head direction.
• After the table is positioned by the
X-axis servo motor, the press head is
positioned by the Y-axis servo motor,
and the material is punched with the
press.

• When the kind or shape of material is
changed, the press head is replaced,
and the positioning pattern is
switched.
• The palletizer is positioned with a high
degree of accuracy by using the 1-axis
servo motor.
• The lowering distance of the palletizer
corresponding to the material
thickness is stored.
• The ATC tool magazine of small
machining center is positioned.
• The relationship between the current
value and target value of the
magazine is calculated, and it is
positioned in the forward or reverse
direction in which the target tool can
be accessed more quickly.
