WE67K CNC Electro Hydraulic Hybrid Drive Pump Press Brake
CNC press brake using a servo-driven hybrid pump-control system in place of conventional valve-control hydraulics.
Features
- Pump control replaces conventional valve control
- Designed to reduce throttling losses and hydraulic overflow losses
- Servo drive reduces noise during idle, release, pressure-hold and return
- Rapid servo braking and pressure/flow cutoff described for emergencies
- Lower thermal equilibrium temperature described; manufacturer says no cooling device required
Manufacturer performance claims
The catalogue claims 50% energy savings, installed power at 50% of its stated theoretical requirement and a 75% reduction in hydraulic tank volume. It also describes longer hydraulic component life and a lower thermal equilibrium temperature.
Controller choices
The controller options shown with the hybrid spread are Delem DA53T, DA58T, DA66T and DA69T; Cybelec CybTouch 8 PS, 12 PS and 15 PS; and ESA VIS-640. Their listed displays, programming functions and interfaces are detailed under listing 3. Controller choice and enabled functions depend on the ordered configuration.
Configuration and specifications
The hybrid spread describes the drive concept rather than a separate model-by-model standard component schedule. The CNC reference tables after listing 5 require confirmation before their capacities or dimensions are assigned to this hybrid version.
