The cutting series blade is mostly used for longitudinal cutting paper, adhesive tape, magnetic tape, film, gold, silver, copper, aluminum, titanium alloy foil and so on. These top grade foil materials require for high precision, no burr and no impression, so it is much hard to cut. Aiming at this difficult problem of high precision, smallest cutting resistance, high wear resistance and long-term sharpness, our company introduced the most advanced international CNC grinding machines and invited blade experts. Through long-term research, we have developed new product substituting the imported high-precision micron longitudinal cutting blade. Apply high-tech technology; carry out ceramic compounding and surface carbon tungsten plating; then the blade will not be easy to wear out and not adhibit powder, greatly reducing friction during cutting. Resolving this problem, cutting precision and speed is greatly improved; service life of blade is prolonged. The development of this blade successfully saves cost for user.
