II. HOW TO USE THE VACUUM TABLE (CONT.)
Vacuum Hold-Down - 1
The Techno Vacuum Table is very effective in
“holding down” parts to be routed. For this method
to work and work well, simple procedures need
to be followed. First, you need to defi ne the
area where your workpiece will be positioned on
the vacuum table. Second, using the red rubber
plugs, you need to plug-up and close-off all of the
area outside your defi ned work area. Fill in ALL
the vacuum grid holes outside your defi ned work
area with the plugs and leave the holes within your
work area open. Next, use the black foam rubber
gasketing to section/wall-off your work area. The
idea is to create an area of concentrated vacuum,
which will generate the greatest amount of vacuum
“hold-down.”
Vacuum Hold-Down - 2
After you have defi ned your workpiece
area and closed off all the vacuum
outside of that area, there is another
option to greater your vacuum: the
vacuum control valves. Each valve
controls the fl ow of vacuum to two rows
of extrusions. Turn ON (valve vertical)
the valves that pertain to your work area
and turn OFF (valve horizontal) the ones
outside of that area. This will concentrate
all the vacuum “hold-down” capacity to
your defi ned work area.
NOTE: You do not need to plug vacuum
holes in a section that has the valve
turned OFF.
WARNING: Proper care should be taken to make sure that objects held down with the vacuum table
are secure. There is a danger that objects held down with the vacuum can become loose and could be
thrown by the action of the cutting tool. Proper safety precautions against fl ying debris must be taken.
Safety glasses must be worn when the vacuum table is being used.
Important Gasketing Installation Notes:
1) DO NOT STRETCH the gasket material while
inserting it into the gasket slots. This will
produce tears in the gasket material which
causes leaks leading to the loss of vacuum
and unsecure pieces fl ying off of the vacuum
table.
2) When joining two separate pieces of gasket
material, make sure to push them together
so the two pieces forma tight seal.
