VIPER 500 - HÖFLER CYLINDRICAL GEAR GRINDING MACHINE

The VIPER 500 cylindrical gear grinding machine is designed for component diameters of up to 500 mm and is optimally suited for small to medium-sized batches. To suit individual requirements, the machine is available in three different configurations: profile grinding, small grinding wheels for custom jobs and multiple-wheel technology (K) and generation grinding (W) . The special machine axis arrangement is a contributing factor to the machine's tried-and-tested precision, consistent quality and tremendous flexibility. The highly dynamic axes allow optimized 5-axis machining of wide variety of modifications in the shortest possible grinding time.
