Pure Electric Press Brake

A pure electric press brake utilizes servo motors and ball screws instead of traditional hydraulic systems to generate bending force. The servo motors drive the ball screws, converting rotational motion into precise linear movement. This controls the vertical displacement of the ram (upper beam), which presses the metal sheet against the die (lower tool) to achieve the desired bend angle.

Key components include:

Servo Motors: Provide high-precision torque and speed control.

Ball Screws: Ensure accurate force transmission with minimal friction.

CNC System: Programs parameters like bend angle, depth, and speed.

Advantages include energy efficiency (no hydraulic oil), reduced noise, faster response, and minimal maintenance. The electric design eliminates oil leaks and ensures consistent repeatability (±0.01mm), ideal for complex or high-volume sheet metal fabrication in industries like automotive and aerospace.

Pure electric press brakes offer significant benefits over hydraulic counterparts. Energy efficiency stands out, consuming up to 60% less power by eliminating hydraulic pumps and oil. Precision and repeatability (±0.01mm) are achieved via servo motors and CNC systems, ideal for complex, high-tolerance bends. Faster cycle times and instant response enhance productivity. Maintenance is minimal due to no hydraulic oil, filters, or leak-prone components, reducing downtime and lifecycle costs. The eco-friendly design avoids oil waste and contamination, aligning with sustainability goals. Low noise operation (below 75 dB) improves workplace comfort. Flexibility in programming enables rapid adaptation to diverse part geometries. These features make electric press brakes ideal for automotive, aerospace, and electronics industries seeking speed, precision, and cost-effective production.
