Laser engraving machine in the application of cutting glass
Glass laser engraving machine laser cutting speed, high precision positioning accuracy. Produce gifts, panel lens chassis, model toys, advertising light box signs show supplies and packing boxes.
① cut effect: the incision without fire polishing, very smooth, bright, no sawtooth pattern, one-time cut acrylic thickness 20mm;
② laser tube of good quality, long life: the best machine-made laser tube, not only stable, life expectancy is long (about 8 to 14 months), power 80W, available for one year;
③ machine performance: can non-stop 24 hours a day work, the original guide, accurate and durable;
④ cutting speed: as for cutting 3mm thick acrylic sheet;
Laser lead to separation:
Laser cutting is another key component of quenching gas (water) mouth, as the movement of the laser spot, quenching gas (water) mouth to cold air (water) blown glass surface area for rapid quenching of the heating, the glass along the the maximum stress direction is broken, which will set the direction of the glass along the separation. It should be noted that in order to cause the glass crack, need to use the mechanical method the starting point of the cut line to draw the starting small cracks.
Choose a different laser power, spot scanning speed processing parameters, stress fracture caused by the depth of up to 100 microns to several millimeters, which means using the laser method may further cut depth of 100 microns to several millimeters of glass. Because this process depends on the thermally induced mechanical stress, fracture depth and cutting speed and expansion coefficient of the material itself is very relevant. In general, the method for laser cutting of glass expansion coefficient should be a minimum of 3.2x10-6K-1, Fortunately, the majority of ordinary glass are to meet this requirement.
Results and applications:
With traditional mechanical cutting method, this new approach has several important advantages. First, it is a step to complete, the dry process. Edges smooth and tidy, cleaning and polishing does not require follow-up. Also, the laser separation process produces a result of high intensity, natural temper of the edge, no micro-cracks. Using this method, to avoid unexpected cracks and broken, reducing the defect rate, increase production.
