General Information
The dual spindle drive ensures a smooth and central pulling action with a consistent broaching speed. The machine is primarily designed for cutting keyways up to 20 mm (for broaching tools from 16 mm width only with stepped tool shafts). The machine’s design enables fast and easy setup for broaching with flat broaching tools for keyways. The universally constructed pull bridge and machine table allow broaching with both profile and flat broaching tools. Profile broaching is possible without additional pull heads, simply using centering bushes. Broaching tools and mandrels compatible with the machine are available upon request.
