Tianjin Wujia CNC Machine Tool Co., Ltd. is one of the leading manufacturers and suppliers of pump-controlled dual-servo cnc bending machine in China. Please rest assured to wholesale high quality machines at competitive price from our factory. Good service and cheap products are available.
This pump-controlled dual-servo CNC bending machine is a mid-to-high-end model widely praised by employers in the sheet metal industry. Unlike traditional electro-hydraulic bending machines, it doesn't rely on a cumbersome hydraulic valve assembly; instead, it uses a servo motor to drive the oil pump. This transmission method is particularly direct, resulting in crisp and clean slider movements without any sluggishness or dragging. The pressure output is also stable, without fluctuations.
Most notable is the pump-controlled dual-servo CNC bending machine's dual-servo system, where the left and right cylinders are independently controlled. This ensures that even when bending sheet metal several meters long, the angle remains consistent throughout, preventing issues like incorrect angles in the middle or tightness at both ends and looseness in the middle. In mass production, the high precision and uniformity of workpieces naturally reduce the scrap rate.
The pump-controlled dual-servo CNC bending machine also boasts significant energy savings. Unlike older hydraulic presses, it doesn't consume electricity by idling as long as it's turned on. Pump-controlled technology delivers only the required amount of oil, with the motor essentially idle during standby. For factories operating two or three shifts daily, this translates to significant electricity savings over a year. Furthermore, the slower oil temperature rise extends the lifespan of hydraulic oil and seals, keeping the workshop floor dry and minimizing leaks.
The pump-controlled dual-servo CNC bending machine boasts an impeccable structure, constructed from thick welded steel plates. After welding, vibration aging treatment thoroughly eliminates internal stress. Even under heavy loads and high-speed operation, the frame remains resistant to deformation. The high precision machining of the worktable and slide, coupled with automatic deflection compensation, provides confidence when bending thick or long plates. The machine's overall rigidity and low vibration are beneficial for mold protection and improved workpiece quality.
Operation is also quite worker-friendly. The system interface is intuitive, with graphical programming, allowing new apprentices to quickly learn. Simply input the plate thickness, angle, and dimensions, and the machine calculates automatically, eliminating the need for experienced technicians to repeatedly experiment. With hundreds of programs stored, product changes can be directly called upon, completing the changeover in minutes, making it particularly suitable for today's high-volume, multi-variety orders. The backgauge positioning is also highly accurate, greatly improving efficiency.
It can handle carbon steel, stainless steel, aluminum plates, and galvanized sheets. From automotive parts to chassis and cabinets, and even structural components for new energy vehicles, the processing results are consistently stable. Compared to single-servo models, it offers better precision and stability; compared to all-electric models, it has stronger load-bearing capacity and a more affordable price, making it a well-rounded machine.
Routine maintenance is simple due to its simplified structure and fewer pipelines, resulting in fewer potential failure points. Regular maintenance involves checking the hydraulic oil, timely lubrication, and changing the filter; frequent repairs are unnecessary. Many factories have used it for five or six years with its precision still consistently high, rarely experiencing major production disruptions.
In short, this is a very practical machine that doesn't rely on fancy specifications. It doesn't focus on flashy parameters; it prioritizes high efficiency, high precision, and a low failure rate. If you have stable orders and are looking for a reliable, long-term partner that doesn't break down easily and can save you costs, this pump-controlled dual-servo CNC bending machine is indeed a very safe choice.
