Broaching machine for broaching from underneath of angles onto workpiece

摘要

The broaching machine has a large number of work tools (11) which are located in a vertical plane. All of the work tools have a component moving parallel to gravity during the broaching process. The broaching work tools feed in two diagonally opposite guiding blocks (12,13) relative to the centre of the workpiece. All work tool guides are matched to each other in a common guide plane (15) by underlying plates (14).
