Speed Viper 300

HÖFLER Cylindrical Gear Grinding Machine

The New Force In High-Productivity Generating Grinding

The Höfler cylindrical gear grinding machine Speed Viper – which focuses on high-productivity generating grinding in large-series manufacturing – draws on the successful concept of the Viper 500 series. It is available in four different configurations based on individual requirements. The Speed Viper 300 is designed for maximum workpiece diameters of 300 mm. In addition to toothed gears, it can also grind extra-long shafts. This is possible thanks to a distance between centers over table of up to 1,100 mm. More information at www.speedviper.com
