Cutting Akril Down
Akril is an Australian made environmentally friendly, highly engineered polymer, enhanced with colour. Quite simply, it
offers a new source of design inspiration kitchen and sliding doors. Being half the weight of glass and 25 more impact
resistant Akril is the logical alternative providing a safe environment for families knowing Akril will not shatter when hit
with force.
Circular Saw
Always cut Akril on a flat secured surface.
With quality equipment, an excellent edge finish can be
achieved with Akril. The main factors in achieving the best
possible outcome with a circular saw are:
• Panel rigidity. Clamp the sheet on both sides of the cut.
• Saw stability. Always use a good quality fence or guide
to improve saw stability and straight-line cutting.
• Saw bearing quality. The price of a circular saw can be
a good indication of the quality of the bearings used
inside. Cheaper saws often use bushes that offer little
to limit the blade’s sideways float, and will begin to
wear quickly. This will have a dramatic impact on cut
quality.
• Blade selection. Always use a blade with the correct
cutting geometry. Aluminum blades generally work
well with Akril.
Reduce the cutting depth to allow the blade to cut
approximately 7mm through the Akril, preferably cutting
into a sacrificial MDF board or similar.
Circular Blade Geometry and
Conditions
Circular Blades for Akril.
Akril is best cut using fine-tooth Aluminum circular blades
with either a ”hollow ground” geometry or a “triple chip”
blade with the following geometry and conditions;
Blade Diameter
255-305mm
Number of Teeth
80-100
Tooth Thickness
3-3.5mm
Clearance Angle
15-20°
Cutting Angle (Rake)
-5°
Cutting Angle of Setting Band
2-3°
Blade Speed
3000-5000rpm
Surface Speed
3000-4000m/min
Hole Saws
Hole saws should be sharp, but the pilot drill blunt. It is
recommended to drill the hole saw half way through, then
turn the Akril over and finish the hole.
This prevents the edge from “blowing out”. De-bur the
edge with 100-grit sandpaper.
Determine the position of the outlet on the panel and mark
the centre. Now mark 20mm either side of the centre
mark. Drill each hole with a 65mm hole saw.
Cutting of Penetrations
When measuring and marking for cut-outs around power
outlet boxes etc, ensure enough clearance is given for the
switch body and that the cover plates or bulkhead fittings
will cover the finished cut-outs.
Use an approved sealer to seal the edge and a 50mm
perimeter of the painted side of any Cut Outs.
