Our Report
Get a ALU-angle 30mm x 20mm x 3mm at a builders merchand, where they are around 8,00€ per piece.
Shorten the profile with a hand saw to 570mm length (machine Z-720)
If the profile is a little longer, you can shorten it later with HEIZ S-720 - once clamped. (instructions to follow - you would need an object-pick-up kit - not yet possible, we are still at the beginning) :-)
Drill two holes into the profile with diameter = 6.2mm centred at 544mm (Z-720)
Attach 4 grove stones - for perfect operation make sure the stones are orientated in the right direction. (Sybject to be discussed in ‘groove stones’)
Use an M6 x 8mm screw, a larger screw of M6 x 10mm will touch the lower profile and therefore needs a washer.
In order to retain the right angle postition the left profile directly at the block where the spindle connection is.
Despite our large CNC-konwhow, we wanted to start from scratch. (we have scrutinized 2 drill bits, D=2 just yesterday.) :-(( So, how to proceed??
I assume that you have positioned the aluminium angles 30x20x3 on your machine.
My idea was to mill into timber or perspex.....complete nonesense!!
Get a sheet of hard insulation foam from a builders merchant (see picture). they come in 1000mmx500mmx20 and cost around 3,60€ per piece.
The sheets are labelled ‘JACKODUR’ and is originally used as insulation material for buildings. Surfaces are very smooth (pay attention not to take the once which have a rough surface, these are not suitable for us).
You can cut the sheet to 200mmx300mm with a carpet knife (dimensions are our idea)
If you now had a vaccuum sheet you could mill our sheet foam exactly to the right angle with the machine S-720. (But for now, we will produce such a vacuum sheet - therefore try to cut the sheet as exact as possible)
Now fix the cut sheet inbetween the Alu-angles as mentioned above. (see picture)
It is soon time to start the milling operation (note to zero location will follow)
We have designed an ACAD software which actually produces paper with a 10mm grid and has an exterior frame of 5mm radius.
We worked with a 2mm drill bit and used a depth of 1.5mm.
