FABRICATING PRESCRIPTIONS
In order to guarantee a perfect end product, the following guidelines should be adhered to during the
production process.
II.1.1
Metal-removing operations
Metal-removing operations are understood to mean all mechanical operations such as sawing, milling,
drilling, punching and cutting. For painted profiles it is essential that the paint coatings do not come off
on the edges during these operations. Therefore it is very important for the quality of the connections
that:
- the metal-removing tools are appropriate and sufficiently sharp;
- the machines are well adjusted (e.g. number of revolutions);
- the tools are regularly checked;
- the metal-removing tools are greased sufficiently and correctly: Reynalube cutting grease block
(art.nr. 086.9190.--) for saw blades, cutting spray (art.nr. 086.9175.--) for punch tools or the cooling
agents and lubricants prescribed by the machine suppliers;
- the appropriate clamp blocks are used;
- the cutting table is free of swarf and dust;
- possible cooling is done by means of chemically neutral products which do not attack the surface
treatment.
Position/clamping of the profiles during cutting:
The position of the profiles on the sawing table during cutting is very important and is the basis to get
perfect mitres after assembly of the sliding elements.
The biggest clamping pressure should always be on the "reference side" of the profiles.
The "reference side" has to be put perfectly horizontally or vertically on the sawing table.
The clamp blocks should possibly be used:
a. to ensure that tolerances on the profiles do not influence the quality of the mitre;
b. to ensure that the profiles do not twist on the table.
Reference side ->
INCORRECT CLAMPING
FAULT: The clamping pressure is on the upper side of the
profile, allowing it to twist during cutting.
CONSEQUENCE: An oblique saw cut resulting in the out-side
of the profile being shorter than the inside.
RESULT: On assembly, the corner is closed on the inside and
open on the outside.
CORRECT CLAMPING
Here, the clamping pressure is on the rebate side of the profile,
and the visible side undergoes a smaller, secondary pressure.
The profile is prevented from twisting or deforming during
cutting. A perfect joint is obtained on assembly.
Remark: It is recommended to exhaust the swarf during the
cutting.
