7. 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 glass mirror with the painted side face down on the cutting table.
•
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.

options.
Edge grinding
YES
Edge treatment
YES
Drilling
YES
Notchings
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°.
•
Processing on the painted side of glass must be smooth and free of glass cullets to prevent the
risk of corrosion.
•
Use non-abrasive coolant additives (neutral pH) to prevent damage being caused to the paint
layer.
•
Clean the cooling water circuit regularly to remove glass particles and plastic particles
originating from the safety backing film.
•
Wash processed products immediately, preferably with deionised water, and dry carefully,
especially around the edges.
•
Use spacers when stacking processed products.
