Partnering with CN-HAWE, the controller manufacturers provide extensive application libraries and tailored development services, enabling users to fine-tune machine settings to meet specific needs. These advanced software tools assist operators in optimizing bending sequences, forecasting material rebound, and minimizing trial-and-error processes, which collectively boost efficiency and elevate product quality.

In summary, the 2HPA series press brake has emerged as a preferred choice across numerous industries, particularly in processing large metal components, thanks to its outstanding performance and flexibility. Whether utilized as a standalone machine or integrated into complex automated production lines, it delivers efficient, precise, and dependable solutions.

CNC Controller

CNC controllers serve as the backbone of motion control in press brakes. At CN-HAWE, we primarily utilize controllers from three leading global manufacturers: Delem from the Netherlands, ESA from Italy, and Cybelec from Switzerland.

Optimal tuning is essential for enhancing the compatibility between the controller and the machine. By integrating our proprietary assembly process with state-of-the-art tuning methods, we enable a range of premium optional features for customers to select from.

CN-HAWE controllers deliver exceptional precision and efficiency through advanced functionalities such as real-time angle adjustments, robust 2D/3D programming capabilities, and sophisticated multi-axis control, ensuring consistent high-quality performance.

Back-gauge

The CN-HAWE back-gauge system leads the press brake industry with its exceptional motion precision.

To ensure superior accuracy and consistency in the production process of CN-HAWE’s CNC series press brakes, we utilize imported ball screws and linear guides. Additionally, the entire back-gauge frame undergoes high-temperature tempering, a process that eliminates internal stress, enhances metal plasticity and toughness, and prevents precision degradation caused by frame deformation over time.

For the stop fingers, we have implemented a synchronous pulley mechanism driven by a servo motor. This innovative design delivers enhanced control performance and precision for the CNC press brake machine's back-gauge system.

Main Servo Motor

Servo motors have emerged as the leading technology in industrial automation, offering exceptional dynamic performance and enhancing machine productivity with minimal energy consumption. This makes them the top choice for many businesses. Compared to conventional motors, servo motors can reduce energy usage by up to 35%, enabling customers to significantly boost efficiency while lowering production costs.

Additionally, we offer high-efficiency, energy-saving motors from Siemens, a renowned German manufacturer, to cater to customers' standard production needs. These motors outperform standard models in terms of efficiency, delivering notable improvements in operational productivity. Built with cutting-edge technology and innovative design, they ensure consistent and reliable performance across a wide range of operating conditions. Whether functioning at high or low speeds, these motors maintain exceptional efficiency and precision, meeting the stringent demands of customers for both production efficiency and product quality.

Servo Hydraulic System

A CNC press brake's servo hydraulic system is comprised of essential components such as the motor, oil pump, filter elements, valve assembly, hydraulic cylinders, and oil tank. To ensure reliability and performance, we have partnered with HAWE, a renowned German manufacturer. Their products are known for their exceptional performance and low failure rates, providing a robust foundation for our system.

Furthermore, our hydraulic control system utilizes an electro-hydraulic servo synchronization design, which minimizes the interval between hydraulic cylinders. This design improves resistance to eccentric loads, ensures precise synchronization, and delivers outstanding power density ratios—all while maintaining cost efficiency. The system's pressure is adjustable, allowing it to accommodate varying bending force requirements and adapt seamlessly to a wide range of practical application scenarios.

Oil Pump

The CN-HAWE oil pump is crafted from high-strength cast iron, ensuring enhanced stability and reliability during operation while allowing it to endure high pressure and heavy loads. Its innovative internal design incorporates a precise mechanical structure and an optimized process flow, significantly boosting the pump's efficiency and overall performance.

One of the standout features of this oil pump is its noise reduction capability, which minimizes operational noise and creates a quieter working environment for users. Moreover, the pump demonstrates low sensitivity to oil contamination, enabling it to function effectively even in oil conditions with impurities. This resistance to pollution not only enhances its durability but also significantly extends its service life.

Punch & Die Tools

Before placing an order, it is crucial to carefully consider the selection of suitable press brake punches and dies. Choosing the right combination is key to achieving the desired bending results. For heavy-duty 2HPA tandem models in particular, we offer fully customizable tools designed to meet specific requirements. This personalized approach not only fulfills customer needs but also helps avoid unnecessary complications. Our custom tooling solutions are precisely crafted to match the exact bending specifications provided by our clients.

Crowning System

CN-HAWE currently specializes in two primary product lines: electric lower crowning compensation systems and a full range of upper and lower hydraulic clamping and crowning systems. Our innovative design calculates compensation values by assessing the overall deformation of the slider and workbench.

This approach ensures precise alignment between the deformation curve of the slider and the compensation curve, guaranteeing exceptional straightness and angular accuracy during the production and operation of our press brake solutions. These advancements not only dominate a substantial share of the domestic market but are also exported to numerous countries across the globe. Furthermore, our strategic collaboration with the Dutch manufacturer Wila enables us to offer premium, high-end products tailored to meet the specific demands of European and American markets.

Bending Follower

Press brakes feature two types of front followers: integrated and floor-standing. The automatic bending follower is fully embedded within the CNC system controller, working in perfect harmony with the press brake's motion control cycle. This integration makes bending large sheet metal plates safer and more efficient, significantly reducing time and labor requirements throughout the product's lifecycle.

When it comes to bending ultra-long and ultra-thick plates, our 2HPA series tandem press brake offers exceptional advantages. Its flexibility and adjustable height and position capabilities allow for a substantial boost in efficiency, making it an ideal solution for handling such demanding sheet metal tasks.
