CNC Electric Servo Press Brake PB5-4015
Product advantages
High-Efficiency Bending
Driven by a seryo motor with high response speed the processing efficiency is more than 1.5 times higher than that of traditional hydraulic press brakes. The ram approach speed reaches up to 30 mm/s, approximnately twice that of conventional electro-hydraulic press brakes.
Stable Precision
Bending speed can be adjusted according to different workpieces, utilizing optimal algorithms and motion trajectory control to enhance bending accuracy. Compared to traditional all-electric servo press brakes, this system eliminates belts and gear reducers, The seryo motor directly drives the ball screw, ensuring bending angle deviations within +0.5°, offering more stable precision.
Eco-Friendly and Energy-Saving
Consumes approximately 70% less energy than traditional electro-hydraulic press brakes. No hydraulic oil is required, making the system both energy-efficient and environmentally friendly.
User-Friendly and ow Maintenance
The drive system is simple, with no consumable sealing parts and no risk of oil eakage. Only periodic lubrication is needed, reducing maintenance costs. The operating system is easy to use, making operation more convenient and worry-free.
Rear Gear Positioning Bearings (15 Years Without Deformation)
The standard CNC backgauge is equipped with six axes: X, R, Y1, Y2, Z1, and Z2.The X-axis controls the overall horizontal (front-to-back) movement of the backgaugefingers.The R-axis controls the vertical (up-and-down) movement of the backgauge fingers, significantly improving operational efficiency and reducing labor intensity by making height adjustments easier.The Y1 and Y2 axes control the vertical movement of the upper beam.The Z1 and Z2 axes control the independent horizontal (left-to-right) positioning of the two backgauge fingers.This six-axis configuration demonstrates outstanding efficiency and flexibility, especially for applications requiring frequent changes in sheet width or angled bending.


Servo Motor
With ball screw drive ensures higher precision., greater stability, and improved efficiency. It achieves processing speeds of up to 200mm/s, with a repeat positioning accuracy of ‡0.01mm.

Ball Screw and Linear Guideways
Featuring high-precision ball screws manufactured by HIWIN, this system offers enhanced positioning accuracy. Combined with a fully equipped backgauge, it ensures faster and more efficient bending operations.
