The single-edge column knife features a sharp cutting edge, ample chip clearance, and excellent heat dissipation, effectively preventing issues like adhesion, burning, and discoloration in plastic materials such as acrylic and PVC, resulting in smooth and glossy cutting surfaces. With minimal cutting resistance and slight vibration during operation, it imposes low load on the machine, making it ideal for high-precision vertical cutting, slotting, and drilling. Compared to multi-edge column knives, it is less prone to burring, delivers cleaner cuts, and requires no secondary polishing. Its simple structure, high sharpness, low breakage rate, and cost-effectiveness make it the preferred tool for efficient precision machining of soft in advertising engraving, offering outstanding practicality and cost performance.
