Akiles Corner Rounders

Choose the radius by the finished look and the item size. A 1/4" radius is a common choice for business cards, ID pieces, membership cards, covers, and general office materials because it softens the corner without changing the shape too much. Smaller radii look tighter and are often better for compact cards. Larger radii, such as 3/8" or 1/2", make the rounding more visible and may suit menus, signs, or presentation covers. The Diamond 1 includes a 1/4" die, while other radius options can require separate accessories. If jobs change often, keep Akiles corner rounder accessories near the machine so operators can confirm radius choices before cutting.

Akiles corner rounders can handle more than plain paper when the model, die, and stack thickness match the material. The Akiles Corner Rounders group is positioned for paper, PVC, cardstock, invitations, covers, pouches, and similar finishing work. Laminated pieces and plastic covers need extra care because flexible or thick stacks can shift during cutting. Clean results depend on sharp tooling, stable guides, and not exceeding the practical stack height for the material. If edges start to look rough, chipped, or crushed, reduce the lift and inspect the cutting parts. Replacement corner rounder blades and dies matter most for shops that cut plastic, laminated sheets, or heavy cover stock often.

Leave some capacity in reserve, especially with laminated pieces, thick cardstock, poly covers, or mixed materials. Maximum capacity is not always the best day-to-day cutting thickness. A stack pushed to the limit can shift, cut unevenly, or put extra wear on the die. For clean corners, the stack should sit square against the guides and move through the cut without forcing the handle or motor. If the operator has to press harder than usual, reduce the lift and make two passes instead. Production teams should set an internal stack height for each common material, then train staff to follow that setting rather than relying on the highest advertised capacity.

Start with square stacks, consistent guides, and the correct die for the required radius. Keep the side guide or backstop locked so each piece enters the cutter from the same position. Empty the waste tray before scraps interfere with the next cut. Keep small cards, pouches, and poly covers flat so corners do not shift under pressure. For jobs handled by more than one operator, keep a finished sample at the machine and mark the radius used. That makes reruns easier to match. If a project has tight size requirements, cut one proof from the actual material and check all four corners before releasing the full batch for finishing.
