Available from Laser Lines, Synrad's sealed CO2 lasers are used in a variety of industrial processes including cutting, welding, drilling and marking.
As is the case with most fabrics, laser cutting provides a sealed edge that resists fraying, which eliminates the need for additional manufacturing steps to seal or tape mechanically cut edges.
Laser Line's application test called for cutting 22 mil, 9.5oz canvas in order to determine edge quality and cut speeds at various laser powers.
The cutting set-up consisted of a Synrad Firestar laser mounted on a 'flying optics' XY table.
The X- and Y-axis flying mirrors direct the beam down through the cutting head as it traverses the extents of a 0.5m square cutting area.
The 22-mil (0.56mm) material thickness narrows the optics choice to a 63.5mm (2.5ft) positive meniscus lens that produces a 100-micron spot with a 1.8mm depth of focus.
For assist gas, clean, dry air (CDA) was chosen at a pressure of 1.7 bars (25psi).
After setting 25W of power, speeds of 2.54m/min were achieved.
This sample was ran at other power levels to demonstrate the linear cut speed as power is increased.
Using 50W, the cut speed was 5.08m/min and at 100W, cut rates of 10.16m/min were obtained.
On all samples, the edges are cleanly cut with only very slight discolouration on the edge itself.
