本发明的方法是基于高度加压Arbeitsmedums的在封闭的变形空间中循环地作用于条目为空白的塑性变形（13），其中，除了集中在通过工作介质的封闭变形空间和可控制的压力脉冲的空白（13）的区 在相等的时间间隔，并在加工坯料的纵向重复（13）可控制地加入到该装置用于执行该方法由一个工作工具（6）与一个中心盲孔（7）的，具有相同的相关联的径向通道（8）和模具（12） 与插入的空白（13）。 工作工具（6）上设置有进给气缸（1）形成在其中的压力室（2），并通过进给气缸中的活塞（14）（1），具有脉冲变压器（15）。

The inventive method is based on the entry of a highly pressurized working fluid in a closed deformation space for the plastic deformation of a blank (13), wherein additionally concentrated in the zone of the closed deformation space and controllable pressure pulses via the working medium to the blank (13) acting cyclically repeated in equal time intervals and in longitudinal direction of the machined blank (13) can be moved controllably The apparatus for carrying out this method consists of a working tool (6) with a central blind bore (7), associated with the same radial channels (8) and a die (12) with inserted blank (13). The work tool (6) is in which a pressure chamber (2) formed with a feed cylinder (1), and by a plunger (14) in the feed cylinder (1) with a pulse transformer (15).
