Advertising engraving tools prioritize sharpness, excellent chip removal, non-sticking, and smooth cutting surfaces. Commonly used tools include carbide single-edge and double-edge cutters. Single-edge helical milling cutters and single-edge column cutters are suitable for soft plastics like acrylic and PVC, ensuring no yellowing or edge burning during cutting. Flat-bottom and round-bottom engraving cutters are ideal for fine text and pattern engraving. Double-edge straight cutters are suitable for hard materials such as particleboard and solid wood, offering high rigidity and reduced breakage. Tapered ball cutters are primarily used for relief curved surface processing. By selecting the appropriate tool based on material hardness, surface finish requirements, and processing methods—ensuring proper sharpness, number of flutes, and helix angle—the engraving can achieve high precision, smooth edges, and stable efficiency, meeting various processing needs for advertising signage production.
