Transfer at high stroke rates: Mechanically coupled or servo?
Transfer is not transfer: Why the coupling determines output and robustness
In practice, we see two main worlds – and both have clear use cases:
1) Mechanically coupled transfer (on the main drive)
Examples: Trailing finger or rail-to-rail transfer with closing axis
- deterministic synchronicity between press and transfer
- High robustness for series processes
- Ideal if the goal is maximum repeatability and stable timing
2) Servo transfer (for complex motion sequences)
- Freely programmable travel profiles
- Optimizable for demanding geometries, sensitive surfaces, difficult transfers
- Particularly interesting if process windows are to be “opened” via movement
What is important is that the decisive factor is not “servo or mechanics” – but the right system design for the component, material, tool and quality target.
Even the best transfer concept loses money if it comes to a standstill in reality.
