damaged, do not install or commission it.
6. Assembly and installation
Specialist mechanical fitter
6.1. WITHIN A CLAMPING FIXTURE
1. Clamp the vacuum plate with its long side in a suitable clamping fixture. Be sure
to leave sufficient room for the Venturi nozzles and compressed air hose connec-
tion.
6.2. INSTALLATION OF THE COMPRESSED AIR
NOTICE
Damage due to liquid taken up by suction
Liquids that penetrate between the clamping face and workpiece seating face can
damage the Venturi vacuum pump and reduce the coefficient of friction of the work-
piece.
»
Check that the workpiece is securely seated.
1. Connect a compressed air hose with a shut-off valve (included in the scope of
supply) to the screwed connector for the Venturi vacuum pump.
2. Connect the other end of the compressed air hose to the 7.2 mm hose coupling
adaptor.
3. Connect the 7.2 mm hose coupling adaptor to the compressed air supply.
» The compressed air is now installed.
6.3. MOUNTING THE BACK-STOP DISC
i
The purpose of the back-stop discs is the alignment of workpieces on the vacuum
plate.
1. Undo the knurled nut.
2. Rotate the back-stop disc until it projects above the edge of the vacuum plate.
3. Tighten the knurled nut.
7. Operation
7.1. CLAMP THE WORKPIECE TOGETHER WITH THE ADAPTER MAT
CAUTION
Risk of injury due to a loose workpiece
Workpieces that come loose from the vacuum plate can cause injuries.
»
Before starting to machine the workpiece, check that the workpiece is securely
restrained.
» Machining forces must be less than the restraining forces.
» If the workpiece is subjected to higher forces, restrain it using back-stop discs.
» Arrange the back-stop discs to counteract the machining forces or feed move-
ments.
i
Lay the adapter mat between the workpiece and clamping face.
Use the adapter plate to cover the slits not covered by the workpiece.
Milled slots up to 1.5 mm deep in the adapter plate can be accepted without loss of va-
cuum.
The adapter mat can be re-used for workpieces with the same contour
ü There must be no burrs or unevennesses on the contact face of the workpiece.
ü
Contact area between the vacuum plate and workpiece cleaned.
1. Place the adapter mat together with the workpiece to be clamped on the va-
cuum plate.
2. Use the adjustable back-stop discs to align the workpiece on the adapter mat.
3. Draw the workpiece contour on the adapter mat. Remove the workpiece.
4. Take the adapter mat off the vacuum plate and place it on a firm surface.
5. Use hole punches to punch holes in the adapter mat within the marked contour
of the workpiece. Choose a hole diameter larger than the width of the slits. Posi-
tion the holes in alignment with the slits of the vacuum plate.
6. Place the adapter plate with punched holes on the vacuum plate.
7. Place the workpiece on the adapter mat in accordance with the contour outline.
8. Switch on the vacuum and clamp the workpiece.
» The optimum operating pressure for the Venturi vacuum pump is 4.0 bar.
9. Check that the workpiece is securely seated.
» The workpiece is now clamped.
