NANTONG, CHINA – Nantong Baizhuo CNC Machine Tool Co., Ltd. (BAIZHUO), a premier global developer of high-end metal forming machinery, proudly announces the successful delivery and commissioning of its flagship 220T/6100mm Heavy-Duty CNC Press Brake to a prominent metal fabrication facility in Wuhan, China. This successful deployment underscores BAIZHUO's robust engineering capacity to design, manufacture, and deliver extra-long bending solutions that meet the stringent precision demands of modern infrastructure.
In large-scale metal fabrication, processing extra-long sheets—such as 6-meter (20-foot) plates for architectural facades, heavy steel structures, or transport machinery—poses significant technical challenges. The most prominent issue workshops face is structural deflection, which causes the infamous "boat effect" where the bending angle in the middle is wider and less accurate than at the two ends.
To eliminate this headache, the newly delivered BAIZHUO 220T/6100mm model is engineered with a premium closed-loop configuration, specifically designed to bring flawless angle consistency and high efficiency to large-format sheet metal fabrication.
To guarantee micrometer-level precision across a 6.1-meter bending length, a press brake requires perfect synchronization between its control system, hydraulics, and mechanical compensation. Here is how the BAIZHUO 220T model achieves it:
1. Smart Programming with Cybelec CybTouch 15 (CT15) System
The brain of the machine is the high-end Cybelec CybTouch 15 (CT15) CNC controller from Switzerland. Featuring an intuitive touchscreen interface, it streamlines the operator's workflow significantly:
Automatic Calculations: The CT15 automatically computes the necessary bending depth, backgauge positioning, and deflection compensation curve based on the programmed material properties.
Easy Sequencing: It supports 2D graphical profile creation and multi-step sequence simulation, drastically reducing setup times and test-bending waste.
2. Perfect Deflection Control via CNC Mechanical Crowning
Without compensation, a 220-ton force over 6 meters will cause the upper ram to flex upward and the lower bed to deflect downward.
BAIZHUO integrates an advanced CNC Mechanical Crowning Table.
Fully managed by the CT15 system, the table utilizes a series of high-precision internal bi-directional wedges. During the bending stroke, it dynamically creates an exact counter-curve that matches the frame deflection down to the micrometer, ensuring a uniform $90^\circ$ angle from the first millimeter to the $6100\text{th}$ millimeter.
3. Eco-Friendly Power: Servo Pump & Closed-Loop Hydraulics
Traditional hydraulic press brakes suffer from constant noise, high oil temperatures, and energy waste. BAIZHUO eliminates these issues by integrating a premium Servo Drive System (powered by Inovance components):
High Positioning Accuracy: Equipped with high-quality German linear grating scales, the Y1 and Y2 axes achieve a repeatability accuracy of up to ±0.01 mm, ensuring perfect ram synchronization and parallelism during heavy-duty bending operations. This advanced closed-loop control system continuously monitors ram position and automatically compensates for deviations, guaranteeing exceptional bending precision and consistent part quality.
Energy & Noise Reduction: The servo motor operates only when the machine is performing a bending cycle, reducing energy consumption by more than 50% compared to conventional hydraulic systems. In addition, the servo-driven system significantly lowers workshop noise levels and minimizes hydraulic oil temperature rise, helping to extend the service life of hydraulic valves, seals, and other critical components while reducing maintenance costs.
A high-quality press brake must deliver reliable performance for decades. The BAIZHUO 220T/6100mm CNC Electro-Hydraulic Press Brake is built on a heavy-duty welded steel frame optimized through Finite Element Analysis (FEA). The entire machine frame undergoes a strict stress-relief heat treatment process to eliminate internal stress and prevent deformation during long-term operation.
This robust engineering design ensures outstanding structural stability, bending accuracy, and long-term durability even under demanding production conditions.
Sectionalized Quick-Clamping System
To maximize productivity and operator safety, the machine is equipped with a heavy-duty sectionalized quick-clamping system.
Key benefits include:
Fast and convenient tool changes
Secure and uniform clamping across the entire 6100 mm ram length
Reduced setup and downtime
Improved tooling alignment and bending accuracy
Ergonomic design for safer operation
The quick-clamping mechanism ensures that punches are firmly secured during operation while significantly reducing tooling replacement time, making it ideal for high-volume production environments.
Ergonomic Dual Foot-Switch Station: Complete with a prominent emergency stop button, the mobile foot switch ensures the operator has absolute control over the ram movement at all times.
Multi-Axis Backgauge Support: A rugged, servo-driven backgauge system runs smoothly on linear guides behind the bed, ensuring heavy 6-meter plates are positioned flawlessly before every punch.
The successful delivery and seamless setup in Wuhan stand as a testament to BAIZHUO's commitment to quality and precise metal forming engineering. Whether you are forming heavy plates or high-end architectural panels, this machine guarantees the speed, precision, and reliability your business needs to stay competitive.
