YFD-550 CNC vertical engraving machine is mini graphite equipment. With high-speed linear guide rail and ball screw, it can realize both fast feeding and high-precision of engraving. Gantry type frame improves the rigidity of the machine in the high-speed engraving process. With embedded high-speed electro-spindle, it lightens the weight of spindle, and realizes the high-speed engraving and upgrades the surface quality of parts. The power of equipment is greatly reduced by small capacity and low-inertia servo control components. All of theses make it first choice to engrave precisely the electrodes and other small parts.
