Radial forging machines - Concepts

SMX hydraulic radial forging machines

Central to this radial forging plant is the SMX forging machine. It features a highly rigid press frame. Here, four hydraulic cylinders with corresponding tools are arranged in an X shape. Compared to mechanical machines with eccentric drives, our design stands out for its clear, simple, and accessible layout. The hydraulic drive ensures you can freely and flexibly select all important forging parameters.

Yet there is another key advantage of this drive over mechanical types: it provides maximum forging force throughout the entire forging stroke.

Your benefits at a glance

  • Shorter set-up times and higher productivity
  • Forming tools produce a specific mass distribution in the forgings ahead of closed-die forging
  • Integrated die shifting device. This means fast changeover to the next die form within a single forging process
