We\u2019ll explain how to cut them with a saw, a guillotine, and a CNC machine, and how to mill them for bending. <\/p>\n\n<h2 class=\"wp-block-heading\">Cutting a composite panel with a circular saw<\/h2>\n\n<p class=\"wp-block-paragraph\">For straight, vertical, or horizontal cuts, use table saws, frame saws (wall saws), or hand-held saws with a guide:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Maximum cutting speed of about 5,500 rpm and feed rate of up to 30 m\/min.<\/li>\n\n\n<li>A carbide disc with a diameter of 200 to 350 mm, with as many teeth as possible featuring a trapezoidal or flat geometry.<\/li>\n\n\n<li>Pitch of 10 to 12 mm and thickness of 2 to 4 mm, with a positive rake angle of about 10\u00b0 and a clearance angle of 15 to 17\u00b0.<\/li>\n\n\n<li>For angle cuts, tilt the panel or the disc.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Using a saw with a cutting depth of 55\u201365 mm, you can cut several panels at once, as long as the blade enters from the front and exits from the back: this ensures a clean front edge.<\/p>\n\n<h2 class=\"wp-block-heading\">Cut with a guillotine<\/h2>\n\n<p class=\"wp-block-paragraph\">The composite panel can also be cut with shears or a hydraulic guillotine, with a cutting angle of less than 1.5\u00b0. To prevent marking the visible surface, place a protective rubber strip between the machine\u2019s cutting blade and the sheet. Adjust the clearance between the blades so that the edge does not become rounded.  <\/p>\n\n<h2 class=\"wp-block-heading\">CNC Cutting and Milling<\/h2>\n\n<p class=\"wp-block-paragraph\">For facade components, curved contours, openwork, or trays, a CNC router is the best option: it cuts and, in the same pass, mills the folding grooves. Approximate speeds: <\/p>\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Core and Operation<\/th><th>Rotation (rpm)<\/th><th>Feed Rate (mm\/min)<\/th><\/tr><\/thead><tbody><tr><td>FR \u00b7 cut<\/td><td>20,000\u201322,000<\/td><td>8,000\u201310,000<\/td><\/tr><tr><td>FR \u00b7 milling<\/td><td>22,000\u201324,000<\/td><td>10,000\u201312,000<\/td><\/tr><tr><td>A2 \u00b7 cut<\/td><td>24.000<\/td><td>12,000\u201315,000<\/td><\/tr><tr><td>A2 \u00b7 Milling<\/td><td>24.000<\/td><td>15,000\u201318,000<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">The mineral core of the A2 panel causes greater tool wear, which is why diamond (PCD) cutters are used.<\/p>\n\n<h2 class=\"wp-block-heading\">Milling for Bending<\/h2>\n\n<p class=\"wp-block-paragraph\">To bend the panel, a groove is milled on the back side, the core is removed, and the outer sheet is left with about 0.8 mm of material. Depending on the shape of the groove, different bends are achieved: <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Round slot:<\/strong> 90\u00b0 bends.<\/li>\n\n\n<li><strong>V-groove:<\/strong> 135\u00b0 bends.<\/li>\n\n\n<li><strong>Arched slot:<\/strong> 180\u00b0 folds (not on panel A2).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Learn more about our <a href=\"https:\/\/panel-composite.com\/en\/machining\/\">composite panel machining<\/a> service.<\/p>\n\n<h2 class=\"wp-block-heading\">Mistakes to Avoid<\/h2>\n\n<ul class=\"wp-block-list\">\n<li>Cutting without chip removal: The saws must be equipped with a reliable dust extraction system.<\/li>\n\n\n<li>Do not ignore the direction of the film: cut and assemble all the pieces so that the arrows on the film point in the same direction, or there will be differences in tone.<\/li>\n\n\n<li>Drag the panels across the table: hold them on their edges to avoid scratching the visible surface.<\/li>\n\n\n<li>Removing the film too early: Leave it on until the editing is complete (and remove it within one month).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If you&#8217;d prefer to receive the pieces pre-cut, we can provide you with <a href=\"https:\/\/panel-composite.com\/en\/custom-cut-composite-panel\/\">composite panels that are cut to size<\/a>, milled, and folded\u2014ready for installation.
