Machine comparison KER Series
- The new generation of chain manufacturing machines benefits from decades of experience in mechanical machines in order to meet the requirements of high-strength chain materials.
- The WAFIOS control system supports the operator by an easy correction of chain dimensions, its programs facilitate the repeat set-up of a chain and increases the machine's productivity.
- The newly developed chain bending machine KER 4.2 combines conventional chain production with modern servo technology which makes it an important milestone in chain production.
- The software-supported machine monitoring system supports the operator in case of errors, synchronizes the bending and welding machine and reduces rejects.
- Due to the use of servo technology and the roll bending technology of the KER x.2, expensive chain-dependent tools, such as cam segments, as well as their changeover, are no longer required. This reduces set-up times and allows chains to be produced cost-efficiently without oiling and in a surface-friendly manner.
High-end cold-forming process for high-strength chains - KEB and KER series
Chain bending machines of the KEB and KER series are used to cold-bend round steel link chains. Wire material is fed in from the wire coil. The bent chain link can then immediately be electrically welded on a separate machine
