1. Technological Iteration and Intelligent Upgrades
CNC busbar processing machines, core equipment for busbar (copper and aluminum) processing in power systems, are undergoing a profound transformation from mechanization to intelligence. Market data for 2025 shows that the proportion of intelligent models with automatic die change and online inspection capabilities has increased from 18% in 2020 to 35%, and is expected to exceed 50% by 2025. Take the new generation of copper busbar processing equipment launched by Huigong Cloud as an example. Its 10-position die library design and double-row die layout shorten die change time to an industry-leading level. Its gantry-style structure and laser positioning system achieve machining accuracy of ±0.02mm and reduce burr incidence by 50%. This type of equipment also integrates a fully automated control system, enabling the complete punching, shearing, and bending process of complex busbars in a single clamping operation. Combined with a remote diagnostic module, it significantly reduces maintenance costs.

In terms of drive technology, the widespread use of servo motors and linear encoder feedback systems has increased positioning accuracy to ±0.03mm and repeatability to ±0.02mm, nearly double the accuracy of traditional stepper motor-driven equipment. Bion Intelligent's 3D busbar punching and shearing line incorporates German Smart Punch technology, enabling seamless integration between the PLC and machining software through a real-time communication module. This allows for processing speeds of up to 25 meters per minute, supports direct import of 3D drawings, and supports full nesting, significantly improving processing efficiency for large projects.

II. Market Structure and Demand Differentiation

The Chinese CNC busbar machining machine market is expected to exceed 8 billion yuan by 2025, with a compound annual growth rate of approximately 10%, demonstrating significant regional concentration. The Yangtze River Delta region, leveraging its well-developed industrial chain, holds a 45.6% market share. Jiangsu-based companies excel in high-precision CNC systems, achieving an average product accuracy of ±0.02mm, 30% higher than the industry average. The Pearl River Delta region, leveraging its electronics and information industry cluster, leads the research and development of flexible processing units, accounting for 43.2% of the nation's patents related to this sector.

The new energy sector has become the fastest-growing application market, with photovoltaic, wind power, and energy storage projects driving an average annual growth rate of 30% in equipment demand. Taking photovoltaic inverters as an example, the evolution of TOPCon battery technology has driven a 32% increase in demand for specialized processing equipment. The share of offshore wind turbines exceeding 8MW has increased to 40%, driving a 25% annual increase in orders for wide-width (≥600mm) processing equipment. The rail transit sector is also experiencing explosive growth. By 2025, new subway lines will exceed 450 kilometers, driving the busbar trunking market to 8.7 billion yuan. Procurement of equipment for processing thicknesses of 3-12mm and equipped with laser positioning capabilities has increased 4.2-fold over the past three years.

The power industry remains the largest application sector, accounting for 65% of overall demand, but the demand structure has shifted significantly. The construction of ultra-high voltage power grids has driven a 22% increase in the production capacity of busbar processing equipment with a width of 800mm or more. Smart grid transformation requires equipment to have processing data traceability capabilities, and the penetration rate of IoT modules is projected to increase from 34% in 2023 to 51%. Notably, data center construction has fueled demand for heat-dissipating busbar processing equipment, with orders in the Chengdu-Chongqing region exceeding 40% annually.

III. Technical Standards and Safety Regulations

The national standard GB/T39746-2021, "CNC Busbar Processing Machines," implemented in 2022, standardized 28 core indicators, including geometric accuracy and positioning accuracy, for the first time, driving the industry from a chaotic, non-standardized approach to standardized development. The standard mandates an emergency stop button response time of ≤0.5 seconds, a 40% improvement over the previous industry average. It also clarifies the equipment's energy efficiency evaluation system and maintainability parameters (such as MTBF ≥ 1500 hours). Taking Shandong Lijian's DGWMX series as an example, its equipment, featuring fully enclosed protective covers (IP54 protection), photoelectric interlocks, and standardized anti-wear hydraulic oil replacement, has reduced the incidence of mechanical injuries by 82%.

Regarding maintenance, standards require regular inspection of the electrical system and hydraulic oil. For example, punching dies require lubrication every 20 cycles, and bending dies require maintenance every 50 cycles. Equipment manufacturers such as Been Intelligent also offer online video tutorials and remote diagnostic services to help users implement preventative maintenance and extend equipment life.

IV. Competitive Landscape and Future Trends
Foreign brands such as Germany's TRUMPF and Japan's AMADA still dominate the high-end market, with average unit prices of 2.8 million to 3.5 million yuan and machining accuracy generally reaching ±0.02mm. Domestic companies are seizing the mid-range market through differentiated strategies. Manufacturers such as Yawei Co., Ltd. and Jinfangyuan Co., Ltd. have developed specialized machines for lithium battery electrodes, priced between 800,000 and 1.2 million yuan, offering significant price-performance advantages. Policy support is further accelerating domestic substitution. Jiangsu Province is offering a 30% subsidy to companies purchasing high-end equipment, with a maximum of 500,000 yuan per unit.

Future technological development will focus on three key areas: First, AI-driven process optimization. For example, Siemens' new-generation control system already enables automatic optimization of machining parameters. Second, green manufacturing: the proportion of models with oil mist recovery efficiencies ≥98% is projected to increase from 41% in 2023 to 68% in 2025. Third, modularization and shared manufacturing: the rise of regional shared machining centers has led to a 7.8% share of equipment investment driven by third-party machining services. With the implementation of special policies for intelligent manufacturing, equipment with intelligent connectivity and remote operation and maintenance capabilities will become mainstream, with the proportion of intelligent equipment expected to exceed 55% by 2025.

V. Conclusion
As the "industrial teeth" of power equipment manufacturing, the technological evolution of CNC busbar machining machines is closely linked to market demand. From traditional three-station machining to intelligent 3D punching and shearing lines, and from single-function equipment to flexible production lines, the industry is undergoing a transformation from "manufacturing" to "intelligent manufacturing." Driven by the dual forces of the new energy revolution and digital transformation, high-precision, high-reliability, and highly intelligent equipment will become the core of corporate competitiveness, while standardization and innovative service models will provide solid support for the industry's sustainable development. In the future, with the deep integration of AI and IoT technologies, CNC busbar processing machines are expected to further push the boundaries of efficiency and precision, injecting new momentum into the upgrade of global power infrastructure.
