BREAKING: For acrylic sheet up to 1/4” thick, score repeatedly along a straight edge with a plastic cutting tool, or Fletcher Terry Knife. Score to penetrate 1/3 through the sheet. Align the score with the edge of the table and apply gentle pressure to break the sheet along the score line.<br /><br />CUTTING: Acrylic sheet can be cut with a variety of equipment. The selection of blades is critical with regards to the quality of the edge finish. Table, and Panel saws are the best options for high volume straight cuts. Material can be stacked to cut several sheets at one time. When cutting, the saw blade should protrude through the sheet approximately 1/4”. Saw blades, specifically designed for cutting acrylic sheet, are commercially<br />available.<br /><br />CIRCULAR SAW BLADE SPECIFICATIONS :<br />Rake angle 0 -10°<br />Clearance angle 10-15°<br />Blade teeth 80 per 10” blade<br /><br />Blade Diameter/ RPM:<br />6” /6400<br />8” /5000<br />10” /4000<br />12” /3000<br />14” /2800<br />16” /2400<br /><br />Tooth design - Band, scroll, and sabre saws are best for cutting intricate shapes and curves. Again, blade selection and proper feed rate is important to minimize melting or chipping. These saws are excellent for creating templates for vacuum or hand routing, and trimming off excess scrap material.<br /><br />For more detailed assistance, please contact us at 800-323-0620.<br /><br
