Processing.
Definition of the profile lengths.
All connectors within the assembled frame have a thickness of
18,5 mm. This dimension must be deducted from the outer
dimensions of the furniture for each connector to obtain the
exact profile dimensions. E.g. for 2 connectors and an outer
dimension of 400 mm the result is:
Drilling/Milling.
The hole for the grub screws has a distance of 20,5 mm to the cut end
of the profile. A 4,5 mm metal drill is used for drilling, to do this we
recommend a twist drill (e.g. from Würth). In order to drill exact holes
you need a pillar drilling machine with stop or you can use our drilling
and tapping jig, which easily can be adjusted to the different profiles and
standardized drilling positions
(see pages 10|11) . Position 1 is intended
for the connector, the hole should be completely drilled through the
external profile wall, approx. 9 mm, up to the middle
(see on the left) .
Alternatively, the holes can also be drilled by using a CNC milling
machine.
Outer dimension: 400 mm

Dimension of the profile: 363 mm
Cleaning.
Drilling or milling chips must now again be removed
with compressed air.
Inserting of the grub screws.
For the most popular 3 profile colours, we offer the matching threaded
pins which discreetly fit into the overall appearance of the frame. If
necessary, they can also be covered with cover caps.
Grub screws of the size M5 x 6 mm DIN 913 are used to link the con-
nectors with the profiles. These are simply being screwed into the 4,5
mm drill hole with a cordless screwdriver. Thus the steel screw forms the
thread in the aluminium profile, it is not necessary to cut the thread into
the profile in advance.
Work steps:
Place as straight as possible.
Screw through the profile wall completely.
Unscrew the threaded pin again so far that the connector‘s
arm can be inserted without any problems.
Finished: The profile is prepared for assembly.
Cutting of the profiles.
The required length of the respective profile can be cut to size on
commercially available circular table saws with an aluminium cutting
saw blade. A generous saw tolerance of +/- 0,3 mm facilitates the
processing.
Cleaning.
We recommend blowing over and through the profiles completely
with compressed air in order to free them from chips produced during
sawing. This minimizes any potential damage to the surfaces during
further processing.
Depending on the current state and age of the saw blade, a small burr
can appear on the profile edges. This should carefully be removed,
especially if black profiles are being used. In this case we use an
abrasive sponge with a grit of 180.
Cross-sections of black profiles that are not entirely clean can easily be
blackened with a black ink pad..
