The engraving machine bearing knife is an upgraded tool specifically designed for advertising engraving. Its core principle is bearing rotation+eccentric cutting, which solves the pain points of ordinary straight knives such as steering lag, film pulling, and tool breakage.
The cutting tool is equipped with two sets of micro precision ball bearings, one on top and one on the bottom. The blade has a standard eccentricity of 0.25mm and the tip deviates from the center of the tool holder. When the equipment is running, the blade head turns along the pattern trajectory, relying on low resistance rolling of the bearing to drive the blade to rotate 360 ° freely, always keeping the blade facing the cutting direction without the need for additional machine adjustment.
Compared to ordinary engraving knives, bearing knives replace sliding friction with rolling friction, significantly reducing friction and making operation smoother. Paired with high hardness tungsten steel blades, there is no stuttering during cutting and turning. When cutting small text or complex hollow patterns, the incision is clean and free of burrs, and it will not pull materials such as vinyl film and reflective film.
This structure is compatible with a full range of engraving machines such as Roland, Yumu, Muto, and Suma, balancing cutting accuracy and service life, significantly reducing engraving waste rates, and suitable for large-scale advertising material cutting operations.
