Servo Motor and Drives
Servo motors and drives are critical components in a CNC press brake, enabling precise and repeatable motion control of key axes such as the ram (Y1/Y2) and backgauge (X, R, Z1, Z2, etc.).
Servo Motors convert electrical signals into high-precision mechanical motion.
Servo Drives process control signals from the CNC controller and regulate power to the motors.
| Axis / Component | Controlled by Servo? | Description |
|---|---|---|
| Y1 / Y2 (Ram cylinders) | ✅ | Controls the vertical stroke, ensures synchronized movement. |
| X-axis (Backgauge) | ✅ | Controls the forward/backward position of the material stop. |
| R-axis (Backgauge) | ✅ | Controls the vertical position of the backgauge fingers. |
| Z1 / Z2 (Backgauge) | ✅ | Controls left and right finger movement for part alignment. |
| Crowning System | ✅ (optional) | Adjusts table deflection for consistent angles across parts. |
High positioning accuracy (typically ±0.01 mm)
Fast response and repeatability
Energy efficient – power only used during motion
Maintenance-friendly – fewer mechanical components than hydraulic drives
Smooth and quiet operation
Yaskawa
Delta
Siemens
Panasonic
Beckhoff
Mitsubishi
Each brand offers different levels of integration with CNC controllers (like Delem, ESA, CybTouch).
