EPB-C-4520 Full Servo Electric CNC Press Brake

Full electric servo CNC press brake with ESA S860 controller

LZK | Intelligent full servo drive system, high precision, energy saving, durable

Using the dual servo principle, the Y1 (ball screw) and Y2 (right ball screw) axes are controlled by powerful new generation servo motors. Quick response, high speed, low failure.

The EPB-C series is the smallest “all electric” servo driven press brake in the LZK-EPB electric press brake series. The C-series machines are equipped with 1 to 2 ball screws and use a “direct drive system” to manage the force. Each ball screw is capable of generating approximately 25 tons of force. By using these ball screws in a “direct drive system”, our electric press brakes are very affordable compared to traditional small hydraulic press brakes. They are very useful for companies looking to free up the capacity of a large press brake with a small press brake in the shop as well. For average daily use, the power consumption of EPB-C machines is generally lower than that of ordinary electro-hydraulic CNC machines. By eliminating the need for hydraulic oil, customers benefit by eliminating expensive oil change, spare parts, valve and maintenance costs associated with traditional hydraulic press brakes.

LZK | The new generation of ESA S860 control system makes complicated work easy

The ESA S860 control system is mainly used in all-electric servo bending machines. It has powerful functions, rich built-in resources, and has the advantages of safety, high efficiency, energy saving, and environmental protection.


LZK | Dual servo main motor control, fast response, low failure

The EPB bending machine adopts the principle of dual servos, and the Y1 and Y2 axes are controlled by powerful SYNTEC servo motors.
This design achieves the highest speed and precision and ensures extremely low operating costs.


LZK | A variety of mold options to match various bending workpieces, with higher precision and faster speed

A variety of molds can be selected to adapt to the production of various workpieces, so that the bending angle of the bending machine is more accurate and the work efficiency is higher


LZK | Reliable Electrical Systems

Open the door and cut off the power, high-quality SYNTEC servo motor drive, electrical components.


LZK | 4-axis precision fast backgauge

High-precision four-axis back gauge is adopted. It is driven by servo motor, ball screw and linear guide to ensure high-precision operation. Beam height is adjusted by CNC.


LZK |Mechanical table compensation mechanism (optional)

It is made of high-strength steel and has a non-linear corrugated block structure. Driven by a motor, the compensation amount can be adjusted precisely.


LZK | DSP laser protection device

The Italian DSP laser protection device, the DSP laser safety protection device fully protects the personal safety of the bending machine operator and avoids the danger caused by the rapid movement of the slider on the machine tool. A block-shaped protection area is formed for the bending tip to protect the front, middle and rear areas of the tip. The protection area is fixed under the tool tip and moves synchronously with the mold, which ensures that any object below must enter the protection area generated by DSP before touching the tool tip when the mold moves down at high speed. Once an obstruction (such as a worker’s finger) enters the DSP protection area, the DSP will immediately send a signal and interrupt the downward movement of the slider.
