An electric broaching press 1 with electric cylinder 4 having a ball nut assembly with internal linear guide way support 5 is presented herewith. The ball nut assembly 5 is driven by electric motor 2 through set of pullies 4a. Rotational motion generated by the electric motor 2 is transmitted into linear motion by a ball screw and nut assembly 8. The ball screw and nut assembly 8 comprises a ball nut 8a, a ball nut housing 8b, and a ball screw 8c. The ball screw 8c transmits the rotational energy in to linear energy to a piston rod 12. The piston rod 12 causes vertical displacement and is attached to a cantilever support structure 20a holding broach tool to carry out broaching operation.

A punching device for punching a workpiece includes a punching part and a broaching part. The punching part has a punching cutting edge that limits a punching cutting area, the punching part being intended to pierce the workpiece. The broaching part is intended to tear the workpiece later than the punching part, and includes at least a broaching tooth with a cutting edge that limits a cutting area which is greater than the punching cutting area.
