Flow Forming Center
Leifeld FFM 623-5
The flow forming center is particularly suitable for rolling out cylindrical rings which are then finish-formed to weight-optimised truck 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
