Product Details

The Delem DM51 is a classic compact numerical NC controller specially designed for conventional hydraulic press brakes, widely adopted for small and medium sheet metal bending jobs. This press brake NC controller delivers reliable closed‑loop positioning control and ram synchronization, supporting standard axes Y1, Y2, X, R and optional Z1, Z2 backgauge axes for flexible multi‑directional adjustment. As a stable sheet metal bending control unit, it adopts simple numerical programming workflow and supports servo, frequency inverter and proportional hydraulic valve drive schemes. This numerical bending controller is frequently sourced as replacement spare part and retrofit upgrade for legacy bending machines, offering dependable bending precision and easy daily operation for sheet metal fabrication workshops.

Supported Functions

This press brake NC controller supports direct angle programming, automatic bend allowance calculation and spring‑back compensation. The sheet metal bending control unit provides three working modes: manual mode, automatic mode and test mode for commissioning verification. It supports teach‑in calibration, manual jog movement, single bending cycle and continuous automatic bending sequences. This numerical bending controller also includes inch / metric switching, batch counting, material parameter setting, pressure factor adjustment and password protection for stored bending recipes.

Core Functions

Built‑in synchronization algorithm keeps Y1 and Y2 axes moving synchronously to maintain ram parallelism and consistent bending angles. The press brake NC controller precisely drives X, R and optional Z1, Z2 backgauge axes to achieve accurate positioning. It securely saves mould, material and product parameters and retains all stored data after unexpected power loss. Integrated fault indication helps technicians quickly locate encoder, wiring, I/O and drive faults to reduce machine downtime. Its compact panel structure allows direct swap for the original failed controller on older bending equipment.
