ABSTRACT:
The invention relates to a broaching machine comprised of a machine table for receiving a workpiece and being mounted in a machine frame. There is a platform which is driven so as to be displaceable relative to the table, as well as of one or more of axially operating broaching tools, which can be coupled with the platform. The machine table and the platform are displaceable in oppositely oriented directions. The machine table and platform are preferably driven via a common spindle drive. The spindles have two oppositely oriented threaded sections and the machine table and platform each are mounted on one of the two oppositely oriented threaded sections for a driving connection.
