Gear hobbing machine OFA 32 CNC 6

The OFA CNC 6 vertical gear hobbing machine is designed to cut spur gears or helical gears, sprocket wheels, worm gears hobbed by the radial tangential method, gears with longitudinal modification, spline shafts and other types of gearing generated by the hobbing process. The modern design with backlash elimination of hob carriage and table offers hobbing of hardened gears and high speed milling of non-hardened gears with carbide tipped tools. The machine is suitable for mass production as well as piece production. The operation, setting and maintenance of the machine are designed to be simple, swift and easy. The automatic work cycle of the machine along with possible application of a work-piece magazine enables to operate several machines by one operator. In its basic version the machine is equipped with SIEMENS Sinumeric 840D sl control system and drives. There are six controlled machine axes.
