The bearing blade of the engraving machine is a specialized upgraded tool for advertising engraving, with the core principle being bearing self-rotation + eccentric cutting, addressing the pain points of ordinary straight blades such as turning jams, film pulling, and blade breakage.

    The tool is equipped with two sets of miniature precision ball bearings at the top and bottom. The blade features a standard eccentricity of 0.25mm, with the tip offset from the center of the tool holder. During operation, the cutting head follows the pattern trajectory and rotates by rolling with low-resistance bearings, driving the blade to freely rotate 360°. This ensures the cutting edge always faces the cutting direction, eliminating the need for additional machine tool adjustments.

    Compared to ordinary engraving knives, the bearing knife replaces sliding friction with rolling friction, significantly reducing friction and ensuring smoother operation. Paired with high-hardness tungsten carbide blades, it cuts and turns without hesitation, delivering clean edges without burrs when engraving fine text or intricate hollow patterns, while preventing material distortion on vinyl and reflective films.

    This structure is compatible with the entire series of Roland, UPM, Wadachi, and Suma engraving machines, balancing cutting precision and service life to significantly reduce engraving waste rates, making it ideal for large-scale advertising material cutting operations.
