In conventional metalforming operations, the main way to reduce friction between the tooling and the workpiece is to apply a lubricant. Another supplementary method, which has been used for decades, is to introduce ultrasonic energy to the tooling, resulting in microscopic, high-frequency vibrations that reduce friction and improve surface finish.
Since its inception, Amada America, Inc. has provided manufacturers with innovative, productivity-enhancing sheet metal machines, including both fiber and CO2 lasers, turret punch presses, press brakes, automation systems, and software. We accomplish this by carefully listening to the voice of our customers and engineering machine solutions that solve their sheet metal fabrication needs. See us at FABTECH Booth S901.
