Description
What is a pure electric press brake?
A pure electric press brake is a machine tool that bends sheet metal into various shapes and angles to meet market demand. Unlike traditional bending machines, it relies on a servo motor for power transmission. The servo motor drives a large-lead ball screw to squeeze and bend the sheet through the pressure of the upper workbench.

Five Advantages of Fully Servo Pure Electric Press Brake
Energy saving
One of the advantages of pure electric servo drive technology is that the input power of the motor is proportional to the load power. The energy consumption is large during bending, the power is small when the slider is unloaded and upward, and there is no power when the slider stops.
Even if the slider of the hydraulic servo bending machine is not working, the main motor and hydraulic pump will continue to run and consume electricity.
Taking the monthly electricity consumption as a reference, the monthly electricity consumption of the pure electric servo model is only 30%-50% of that of the electro-hydraulic servo model.
Environmental protection
The pure electric servo bending machine does not use hydraulic oil, and replacing hydraulic oil or components is not troublesome. There is no hydraulic oil leakage during the replacement process and daily system, and no waste oil treatment and pollution.
High production efficiency
Compared with electro-hydraulic models, the full servo motor ball screw CNC bending machine has a screw transmission, no switch valve delay, and higher efficiency, and compared with the same type of electro-hydraulic model, the efficiency will be increased by 50%-80%.
High bending accuracy
The bending speed of the pure electric servo bending machine is adjustable. It can set a more appropriate bending speed for different thicknesses, materials, and lengths to improve bending accuracy and maintain high productivity. The main drive of the servo bending machine drives the screw through a servo motor, which has higher transmission accuracy. Measuring the bending angles of plates of various specifications can ensure the bending angle error is within ±0.5°. Compared with the same electro-hydraulic machine, the bending accuracy can be improved by 20%-50%.
Low maintenance and use cost
The transmission system of the pure electric servo bending machine is simple. It requires no maintenance and only regular lubrication.
The hydraulic oil of the hydraulic bending machine needs to be replaced regularly. Pumps, valves, and seals are prone to failure and damage, and the hydraulic system is easily contaminated, which is not easy to detect and troubleshoot. Once the hydraulic system is infected, it is difficult to clean, which will cause environmental pollution.
How do you choose between electro-hydraulic and pure electric press brakes?
When choosing a bending machine, you may face a significant decision: should you choose an electro-hydraulic bending machine (electro-hydraulic servo CNC bending machine) or a pure electric bending machine (pure electric servo CNC bending machine)?
