Flow Forming Center

Leifeld FFM 312-4RS

The flow forming center is particularly suitable for rolling out cylindrical rings which are then finish-formed to weight-optimised passenger car rim rings. Starting parts are cylindrical rings round-bent from a sheet strip, butt welded, burred and expand-calibrated.

Main Characteristics

  • Fast changeover due to automatic mandrel clamping device and/or roller clamping device, as well as horizontal machine design
  • Low space requirement
  • Shorter cycle times due to integrated loading system
  • Flexible material flow by use of robots
  • Wall thickness measuring station for compensation of thickness variations in the material batch
  • No additional trimming required
  • Speed-regulated roller drives reduce wear on the spinning rollers
