Holding the
workpiece
CAUTION
Risk of injury due to the workpiece falling
If the workpiece is very dirty or uneven, it may fall down.
•Only grip workpieces with surfaces that are as clean and even
as possible.
ØApply the vacuum suction unit (4) of the GSW-V to the
workpiece.
✓The vacuum suction unit (4) is slightly flexible so that it can
be used for Z-compensation.
ØSwitch on the compressed air or cooling lubricant supply of the
toolholder.
✓The compressed air or lubricant enters the Venturi nozzle (2)
through the media inlet (1).
✓This causes the Venturi nozzle (2) to generate a vacuum in
the intake duct (5).
✓The workpiece is now securely held.
Note: During holding, the gripper continuously supplies
coolant or compressed air via the outlet port (3).
ØPosition the workpiece using the GSW-V.

Detaching the
workpiece
ØSet down the workpiece at its destination position using the
GSW-V.
✓Use the slight flexibility of the vacuum suction unit (4) for Z-
compensation again if required.
ØSwitch off the compressed air or cooling lubricant supply.
✓The vacuum will no longer be generated.
✓The workpiece is no longer held.
ØLift the GSW-V off the workpiece.
