1. Electric instead of hydraulic drive – Servo-electric presses use an electric drive, which makes them more energy-efficient, quieter and more precise than traditional hydraulic machines.

2. Greater precision – Thanks to servo technology, servo-electric presses provide higher edging accuracy, which is important in the production of parts requiring high precision.

3. Faster response and greater flexibility – The electric drive enables faster and more flexible adjustment of the pressing force and speed, which allows for optimizing the production process depending on the type of material and task.

4. Lower operating costs – Servo-electric presses are more energy efficient than hydraulic presses because they do not require constant hydraulic pressure or large oil tanks, which translates into lower operating costs.

5. Clean and No Oil Maintenance Required – Compared to hydraulic presses, servo-electric presses do not require hydraulic oil, which reduces maintenance costs and eliminates problems associated with oil leaks.

6. Increased Reliability – With no complicated hydraulic system to break down, servo-electric presses are more reliable and require less frequent repairs.

7. Increased energy efficiency – Thanks to the use of servo motors, these presses consume energy only when working, making them more energy efficient than traditional machines.

8. Easy integration with automation systems – Servo-electric press brakes can be easily integrated with automatic systems, which allows for full automation of the production process, including changing parameters in real time, which allows for faster adaptation to changing production conditions.

9. Operation silence – Thanks to servo technology, servo-electric presses operate much more quietly than hydraulic machines, which improves work comfort in production halls.

10. Better control over the bending process – Thanks to precise control over the movement of the press frame, the operator has full control over the bending process, which allows for repeatability and high quality of bends.

Servo-electric press brakes are becoming increasingly popular in the industry, mainly due to their advantages in terms of efficiency, energy saving and precision.

Main Features:

• Front supports: 2 pieces on linear guides, ensuring stability during bending operations

• Y1, Y2 axis adjustment: automatic on servo motors

• Back stop adjustment (X axis): servo drive on encoders

• R axis adjustment: servo drive on encoders

• Automatic adjustment of the deflection arrow (option)

• Double-sided punch mount: AMADA quick mount, allowing for quick tool changes

Technical parameters

Automatic adjustment of bumper departure (X axis) and R axis (manual option). R axis facilitating bending of larger radii, e.g. with a stepper system.

Optional finger adjustment in axes Z1,Z2,R1,R2,X1,X2 on servo motors.

In order for the effect of the performed step bending to be satisfactory, it is necessary to perform certain calculations, which, however, require knowledge of several of the most important parameters related to the bending process - these are:

• Arc length - the distance between the ends of the curve of the bent part of the sheet metal counted on the inside of the bend;
• Number of bends - the number of individual bends that must be performed to obtain a bent sheet metal with a specified radius; the greater the number of bends, the smaller the angle of a single bend and, as a result, the smoother the arc;
• Distance between bends – the distance between individual bends made during the process.

Although the entire step bending process may seem quite complicated, the machines and software available at CORMAK are already at such an advanced stage that in many matters they completely replace the operator.
