3. FD 3600

        The FD 3600 gear cutting machine is designed for machining gears with diameters between 550 mm and 3,600 mm with a weight up to 25 tons. It is characterized by a high degree of accuracy, quality of the teeth surface and the ability to emit a large amount of chips in the time unit. It uses a hobbing cutter tool.
