Slitting machine mainly used in paper, tape, tape, film, gold, silver, copper, aluminum, eliminating items such as alloy foil slitting ... These high-grade metal foil slitting requirements of high precision, Burr, no creasing, cutting more difficult, so high requirements for precision slitting, cutting knives, cut off the least resistance, abrasion resistance maximum sharp cutting edge sustainable. To solve this problem, I introduced the most advanced CNC grinders, tooling technology experts were invited, after a long research and development instead of imported high-precision micro-slitting blade. And apply advanced technologies, the tungsten carbide ceramic composite and blade the blade surface plating handle, blade when cutting, easy to wear and not powder, reduce friction during cutting, solve this problem, greatly improving cutting precision and speed, extended tool life. This tool was developed for users to save significant costs and foreign currency.
