11.2 Clamping a Workpiece
Caution! Danger of crushing hands and fingers between vacuum suction cup and workpiece. Do
not reach into this danger area and wear protective gloves if necessary.
Danger of cutting and abrasion due to sharp workpiece edges and pointed corners. Be careful
with sharp-edged and pointed workpieces and wear protective gloves if necessary.
11.2.1 Clamping the Workpiece with Vacuum Suction Cups
Figure 13: Suction cup valve
•
Before attaching the suction cup, thoroughly clean the workpiece sur-
face of chips, dust and dirt to ensure an optimal holding surface and to
prevent dirt from being sucked into the pump.
•
Each suction cup (whether round or oval) is equipped with a safety
valve that triggers the vacuum by contact with the workpiece.
•
The vacuum is only released after the valve ( V ) has been pushed in-
wards by the workpiece approx. 2 - 3 mm.

The penetration of chips, dust and dirt can damage the vacuum pump!
11.2.2 Clamping a Workpiece with the Universal Clamping Plate
With hole grid table tops, the workpiece can alternatively be clamped via an optional universal clamping plate.
There is a flat version ( Art.-No. 200.405.00) as well as a 90° swivelling version ( Art.-No. 200.406.00) available.
The fixation on the hole grid plate is identical for both versions.
Figure 14: Quick release coupling
•
For fixing on the table, the base plate is equipped with two fixed re-
taining bolts and one loose clamping bolt with matching grid hole spac-
ing. The loose clamping bolt has an additional quick coupling (
K ), which
serves to clamp the clamping plate.
•
Place the universal clamping plate with the two fixed retaining bolts at
the desired position in the hole grid of the table top.
•
Then insert the loose clamping bolt on the opposite side through the
large hole into the grid hole and clamp with quick coupling (
K ) by swiv-
elling to the left (see

Figure 14).

•
y inserting the rubber sealing
strip (D) into the finely milled
grooves, the vacuum range can
be adapted to the size of the
workpiece (see

Figure 15).
•
Thoroughly remove chips, dust
and dirt from the workpiece
surface.
•
Switch on vacuum pump.
•
Place the workpiece and make
sure that it fits tightly on the
fixture.
•
Now the workpiece can be ma-
chined.
•
Before unclamping the work-
piece (after machining), please
follow the instructions in sec-
