In the next five to ten years, multinational auto parts companies will re-adjust all aspects of the value chain of production, procurement, research and development, making China not only an important market, but also an important factor in gaining global competitive advantage. This will also bring new opportunities and vitality to the Chinese auto parts industry. As the largest manufacturer of automotive electric power steering (EPS) in China, Zhuzhou Yileda Electromechanical Co., Ltd. specializes in EPS research and development, production, sales and service, and accounts for 75% of domestic EPS market share. In the next few years, Elite's strategic goal is to become a world-renowned steering system supplier, ensuring the safety and comfort of driving with high-quality products.
Innovation - dissatisfaction is the wheel of progress
EPS is a mechatronics new generation of automotive intelligent power steering system. The principle is that the control module determines the magnitude and direction of the steering assist based on the torque sensor and the signal transmitted from the vehicle speed, and drives the motor to assist the steering operation. EPS is based on the mechanical steering system. According to the torque signal and the vehicle speed signal acting on the steering wheel, the motor generates a corresponding amount of auxiliary force through the electronic control device (control module) to assist the driver in steering operation and obtain Servo system with optimal steering characteristics. It uses the principle of automatic control and feedback to achieve satisfactory steering assistance for drivers under different vehicle conditions, ensuring the safety and comfort of driving.
In 2001, Elite successfully developed the first automotive electric power steering gear with independent intellectual property rights in China, ending the history of domestic automobile EPS dependence import. With the continuous improvement of technical strength, Elite is actively seeking innovative breakthroughs. It has established the first EPS research institute, EPS testing institute and EPS post-doctoral work station in China, and obtained more than 40 patents such as EPS structure, appearance, invention and software, and has the independent knowledge of the electronic components of EPS core components. Property rights, patented technologies cover EPS system control, sensors, product structure and security protection.
Yi Lida's technician Shen Hao said, "Our view of innovation is that dissatisfaction is the wheel of progress. With this philosophy, we are never satisfied with the achievements in the fields of technology, R&D, etc. We continue to innovate for better. development of."
Automated production equipment to help upgrade corporate strategy
From the transformation of domestic EPS leading enterprises to the world's leading steering system suppliers, Elite needs to select first-class production equipment to ensure its high-quality products. “The earliest contact with EMAG was in 2011, and since then it has been using EMAG worm gear processing equipment. The most important reason for choosing EMAG machine tools is its high degree of automation, which can reduce the human factors of the operators in the production process and greatly improve The efficiency of processing.†Yi Lida technician Shen Hao said. It is understood that Yi Lida chose the EMAG K 200 model, mainly used for worm gear processing. In the worm wheel machining process, the consistency of the parts and the accuracy of the worm wheel are required to reach 7C/GB10089. Before the EMAG machine tool is used, the product quality is difficult to achieve relatively high precision and the processing efficiency is relatively low. The EMAG machine just solves this problem. The automation equipment is not only efficient and stable, but also produces consistent parts with high precision.

“The production equipment with efficient automation is an important part of Yilida's strategic goal.†Shen said, “Emmmark equipment has good stability, which provides a strong guarantee for high-quality products, and at the same time, the equipment is highly automated and effectively reduced. Labor costs and improved processing efficiency."
According to reports, the EMAG K 200 is a fully automatic machine with a minimum of 8 active CNC axes. It can solve almost all the imaginary cutting tasks, whether it is equipped with manual loading or unloading or a unique and flexible automation. The K 200 is able to respond quickly to an ever-increasing range of processing tasks, meeting the different requirements of the customer, ensuring maximum flexibility and efficient production processes.
High-precision worm gears produced by the K 200 machine
In addition, the K 200 can be used for soft pre-milling of spur gears and worms, and can be hard-finned using a scraping hob (after quenching) on ​​the same machine, or even directly for already solidified blanks. Rolling processing for the highest product quality in the shortest machining time.
Cooperation and win-win cooperation
Shen Wei stressed: "The relationship between Elite and EMAG is a mutually beneficial and win-win cooperation. In the future, as the competition of auto parts enterprises becomes more and more fierce, we also expect and need to improve the efficiency through the improvement of automation level. And the company's strategic goals."
Since the development of the inverted vertical lathe with reverse thinking in the early 1990s, EMAG Group has taken the lead in automation theory as the basis and development direction of innovation, insisting on independent innovation, and striving to ensure that all its machine tools and production systems are simple. Flexible, stable and high-quality processing at the same time, any form of flexible processing can be carried out to completely eliminate those complex processing systems and manual loading and unloading operations.
"The application of EMAG's automation innovation theory, while effectively improving the processing efficiency, significantly reduces the production cost, and provides an opportunity for the rapid development of small and medium-sized enterprises, especially auto parts enterprises, and becomes the development direction of automation technology. In the future, I believe we will have more in-depth cooperation and development in the field of automation." Shen Hao added.
