USED DMG ULTRASONIC 20 LINEAR

The DMG ULTRASONIC 20 LINEAR is a compact, high-precision 5-axis ultrasonic machining center designed for the efficient machining of advanced materials that are difficult or impossible to process using conventional milling methods. Developed by DMG MORI, the ULTRASONIC 20 LINEAR combines high-speed linear drive technology with ultrasonic-assisted machining, enabling manufacturers to machine brittle and hard materials with outstanding surface finishes, reduced tool wear, and exceptional dimensional accuracy.

Unlike traditional machining centers, the ULTRASONIC 20 LINEAR uses high-frequency ultrasonic vibration superimposed on the rotating cutting tool. This technology significantly lowers cutting forces, minimizes heat generation, and reduces the risk of microcracks when machining ceramics, glass, sapphire, quartz, carbide, zirconia, silicon carbide, composites, and other advanced engineering materials. At the same time, the machine performs conventional high-speed milling on metals including aluminum, stainless steel, titanium, and hardened steels, making it a highly versatile manufacturing platform.

The machine features a rigid mineral cast or cast iron machine structure, direct-drive linear motors, precision glass scales, and a high-speed spindle capable of exceptional positioning accuracy. Its simultaneous 5-axis capability enables complex contour machining, micro-machining, engraving, drilling, milling, and precision finishing in a single setup. The compact footprint makes it ideal for research laboratories, medical manufacturers, aerospace suppliers, semiconductor companies, and precision engineering facilities where floor space is limited but machining performance cannot be compromised.

Most DMG ULTRASONIC 20 LINEAR machines are equipped with Siemens or Heidenhain CNC controls integrated with DMG MORI’s CELOS operating platform. Advanced probing systems, automatic tool measurement, high-speed tool changers, and sophisticated coolant management contribute to exceptional productivity while maintaining outstanding part quality.

Because of its unique ultrasonic machining capability, high-speed linear drives, and premium German engineering, the used DMG ULTRASONIC 20 LINEAR remains one of the world’s most advanced machining centers for precision manufacturing of technical ceramics and difficult-to-machine materials.
