Please rest assured to wholesale high quality machines at competitive price from our factory. Good service and cheap products are available.
This 55T_1250mm High-speed Pump-controlled Servo CNC Press Brake is specifically designed for small to medium-sized precision sheet metal machining jobs. Its biggest highlight is its ease of use and cost-effectiveness. It utilizes a closed-loop control system with a servo motor and variable pump, offering fast response, stable precision, and crucially, exceptional energy efficiency and a small footprint. It's particularly suitable for batch processing of thin sheet metal parts, electronic appliance housings, small lighting components, or small brackets, making it ideal for hardware factories, electronics component manufacturers, and even small workshops.
Let's first look at its basic structure. The 55T_1250mm High-speed Pump-controlled Servo CNC Press Brake's body is welded from a single piece of Q355B high-strength steel plate. After welding, it undergoes vibration aging treatment to eliminate internal stress. The advantage of this design is that the machine body is exceptionally robust and resistant to deformation. Even with frequent, high-frequency use every day, the structure remains rock-solid over the long term. Slight deformation of the machine body won't compromise the accuracy of the bent products. Furthermore, the machine body undergoes sandblasting and electrostatic powder coating, making it rust-proof, wear-resistant, and corrosion-resistant. It can withstand dust and slight humidity in the workshop and will last for many years without problems.
Let's talk about its core performance, which is the hallmark of this 55T_1250mm High-speed Pump-controlled Servo CNC Press Brake. It uses a pump-controlled servo power system, which, simply put, means the servo motor directly controls the oil pump output. Compared to older hydraulic press brakes, it saves 30% to 50% on electricity, and the oil temperature is exceptionally stable during operation, preventing overheating even during prolonged continuous use. This results in lower noise levels, less hydraulic oil consumption, and significantly reduced maintenance. Furthermore, with the addition of a dual-cylinder servo synchronous drive and a closed-loop detection system using a linear encoder, the slider moves incredibly smoothly with extremely high synchronization accuracy, ensuring that a batch of processed workpieces is perfectly aligned in size and angle, with minimal deviation.
Specific parameters:
- Nominal pressure is 550kN (55 tons), worktable length is 1250mm, column spacing is 1000mm.
- Throat depth is 200mm, slider stroke is 150mm, and opening height is 380mm, making mold clamping very convenient.
- Speed is also impressive: the slider's rapid descent and return strokes can reach 120mm/s, and the working speed is adjustable between 5-25mm/s.
- The back gauge also moves quickly, with a movement speed of 200mm/s, a repeatability accuracy of ±0.01mm, and a bending angle accuracy of ±0.1°.
- In terms of processing capacity, it can handle cold-rolled steel sheets up to 3mm thick and stainless steel sheets up to 2mm thick without any problems.
- The standard configuration features 4-axis control (Y1/Y2/X/R) with a main motor power of 5.5kW.
Operation is straightforward. Its CNC system supports graphical programming, automatic angle calculation, and multi-segment positioning. The interface is clean and intuitive, and it supports multiple languages. Operators can easily learn to program and debug with minimal training. The back gauge uses a servo drive, coupled with ball screws and linear guides, ensuring fast and accurate positioning. It easily handles continuous bending with multiple processes and angles, significantly improving overall processing efficiency.
Safety features are also comprehensive, including standard devices such as safety light curtains, emergency stop buttons, overload protection, and leakage protection, meeting general industrial safety requirements and providing peace of mind while working. Overall, this equipment has a compact structure, saves space, and is flexible in installation and relocation, making it suitable even for large factories. If you're looking for a precision sheet metal bending machine that balances efficiency, accuracy, and cost-effectiveness, the 55T_1250mm High-speed Pump-controlled Servo CNC Press Brake is definitely a very practical choice.
