China's CNC bending machine has a promising development prospect
With the continuous advancement of numerical control (NC) systems, manufacturers are placing higher demands on the automation level of machine tools. Modern production models now require more efficient and precise equipment. In the past, when performing multi-channel bending operations, traditional bending machines had to process an entire batch of workpieces at once, which required frequent stops for refueling and adjusting. This significantly reduced production efficiency. However, with NC control, the rack and slider stroke can be precisely managed, allowing for continuous multi-fold bending of a batch of workpieces. This ensures extremely high forming accuracy and consistency across the same batch of products. As a result, production efficiency is greatly improved, and the future of CNC bending machines looks very promising.
A CNC bending machine essentially functions as a CNC-controlled bending mold designed for thin plates. The mold consists of a bracket, a worktable, and a clamping plate. When the coil is energized, electromagnetic force is generated, enabling the pressure plate to clamp the base and secure the thin plate. This method of electromagnetic clamping allows for easy operation and enables processing of workpieces with side walls, making it highly adaptable to specific requirements.
In China, most bending machine manufacturers are concentrated in Bowang District, Maanshan City, Anhui Province. The area is often referred to as “a factory everywhere†due to its overwhelming presence in the industry. The main industries here include sheet metal machine tools such as bending machines, shears, and various types of blades and folding molds. Since the establishment of the district, it has earned five national titles, including the National Cutting Machine Tool and Blade Die Industry Base, the National Scissors Machine Tool Industry Famous Brand Demonstration Zone, and the National Torch High-End CNC Machine Tool and Edge Die Base. These achievements have helped the region expand its industrial reach nationwide and export products to over 120 countries. The five "GuoZiZhao" initiatives have driven innovation and rapid development, pushing the area closer to its goal of "Building Hope."
As one of the key products in the region, the CNC bending machine has seen significant growth. Common models include G, F, and WC67K series. A special type, the plastic plate CNC bending machine, is designed based on the principle of heating and softening thermoplastic materials. It is ideal for bending all types of thermoplastics. The mold features direct bending without splicing, slotting, or welding, resulting in a neat appearance, no leakage, and high structural strength. It also improves processing speed, enhances surface finish, and reduces labor costs by replacing manual welding with fully automatic operations. This leads to better product quality, increased efficiency, and a shorter production cycle.
Today’s CNC bending machines are rapidly evolving in their integration with numerical control systems, CAD, CAPP, and flexibility. They play a crucial role in modern sheet metal forming and have vast development potential. Facing the challenges and opportunities in the machine tool industry, it is expected that CNC bending machines will continue to advance, boosting productivity and driving the progress of the entire industry.
