The device allows the broaching of thin-walled workpieces with high precision and an excellent surface condition. It comprises mainly a fixed support defining a radial abutment surface, a sleeve defining ramps, wedge-shaped members bearing against said ramps and against the outer surface of the workpiece. These wedge-shaped members are carried by a plate which is capable of being brought to a wedging position under the effect of springs or to a disengaged position by means of ramps. |
