4. QUALITY CHECKS
We recommend performing quality checks based on the requirements of standard EN 1036-1:2007
for the following visible factors: float glass defects, optical deformation, scratches, dimensions, etc.
5. CUTTING
▪
The cutting and transfer tables must be covered with felt and cleaned frequently to avoid scratches
caused by small glass splinters that could damage protective paints and varnishes.
▪
Cut the mirror with glass side face upward.
▪
Reduce the pressure applied to the cutting tool to avoid cullets.
▪
When starting, cut slowly and build up pressure until you achieve a good cut.
▪
Use small quantities of neutral cutting oils (e.g. ACECUT 5503 cutting oil or equivalent).
▪
Correct cutting settings can differ from one cutting installation to another and can be tested by
cutting test strips 100mm wide and at least 1m long. It should be possible to break the cut strips by
hand.

6. EDGE PROCESSING & DRILLING
Edge grinding
YES
Edge treatment
YES
Drilling
YES
Notching
YES
▪
Processing quality depends on clean cutting.
▪
Adjust the speed of the processing machine according to the number of grinding wheels fitted to it
and the thickness of the glass.
▪
If using spherical grinding wheels, avoid overly angular shapes.
▪
If processing a flat joint with arise edges, avoid edges with an angle greater than 145°.
