LONGBOW 100% Electric CNC Press Brake
100% Electric CNC Press Brake For The More Demanding Taste
Superior Quality. Reliability In An Economical Machine
EP series Mini Electric Press Brake is a machine that the servo motor advances the heavy-duty ball screw to drive the slider to do reciprocating motion, and then drive the upper mould on the slider to apply force to the lower mould on the workbench, so as to bend the mental plate according to the required shape and size. The Mini Electric Press Brake produced by Longbow Company has the following characteristics: first, the control system adopts the closed-loop control mode: the drive device is the servo motor. Second, the Mini Electric Press Brake will automatically output the proper power electrical energy according to the working conditions, so it is particularly power-saving. Third, environment-friendly and environment protection: no need to use and replace the hydraulic pressing oil, make it free from the pollution of the environment by waste hydraulic pressing oil.

Core Features of 100% Electric CNC Press Brake
Bending machine bed
The bed is the basic support structure of the press brake, which needs to withstand various forces and moments generated by the press brake during the working process. Therefore, the structure and material of the bed have a great impact on the performance and accuracy of the press brake.
The bed of the electro-hydraulic servo press brake usually adopts an integral welded structure, which has high stiffness and high stability. The steel plate of the bed is welded with high quality steel plate, and has high precision and stability after strict annealing and stress relief treatment.
Hydraulic system
The hydraulic station is the core of the hydraulic system, which controls the movement of the machine by controlling the pressure and flow of the liquid. The main motor consists of a servo motor tank made of stainless steel. A hydraulic station usually consists of the following main components:
Hydraulic pump: Hydraulic pump is the power component of the hydraulic system, which converts mechanical energy into hydraulic energy and provides power for the entire hydraulic system.
Crowning
Our independently designed system calculates the compensation value based on the overall deformation of both the ram and worktable. This enables the deformation curve of the bed to align seamlessly with the compensation curve, ensuring optimal straightness and angle consistency in our products.
Manual Upper Tool Clamping
The one-key release fast clamp could ensure the safe and fast punch changing, with strict quality requirements and procurement standards of raw materials, which keeps the punch from falling out.
Ball Screw & Guide
The machine features ball screws and linear guide rails to ensure smooth and reliable operation.
Servo motor
The machine features ball screws and linear guide rails to ensure smooth and reliable operation.
