Company Profile
1. Providing Full-process Services to Customers With the development of the industry, customers have put forward the demand for "turnkey projects" to equipment manufacturers. This has led manufacturers to further integrate the front-end product selection and process design, as well as the back-end services such as personnel training, installation, commissioning, operation and maintenance, on the basis of simple product manufacturing and sales. Enterprises are required to provide full-process services within the application scenarios. As a comprehensive solution provider for intelligent grinding applications, our company can offer customers full-process services. By continuously improving our service capabilities and technical levels, and perfecting the variety and specifications of our products to meet the diverse needs of customers, our company also has strong system integration and engineering package capabilities, and is able to provide customers with comprehensive, effective, customized and high-quality solutions. 2. Competitive Advantages in the Industry As an important supporting equipment specifically used for the precision repair of rolls, the roll grinding machine can perform high-precision geometric precision repair and surface microscopic quality repair for rolls. It is an indispensable key equipment in various application fields of metal sheet rolling production lines, as well as in manufacturing processes such as papermaking and light textiles. Our company's products have successively won many honors, including National Key New Products, National Torch Program, First Prize of the National Machinery Industry, Gold Award for Excellent New Products in Jiangsu Province, the First Set of Products in Jiangsu Province, Special Prize for Scientific and Technological Progress in Jiangsu Machinery Industry, and National Excellent Patent Award. 3. Advantages in Technological R&D Huachen Equipment has been deeply engaged in the field of high-end precision grinding equipment for nearly 20 years and has established a complete R&D and innovation system. The company has a high-quality technical R&D team, gathering more than 100 professionals in various fields such as machinery, electricity, mechatronics, materials, and software development. It has formed nearly 100 core intellectual property rights, including 46 invention patents, 39 utility model patents, 1 design patent, and 11 software copyrights. The company jointly constructed the Engineering Research Center for High-precision Roll Intelligent Manufacturing System of the China Machinery Industry Federation with Tsinghua University, which has been highly recognized by the industry. At the same time, the company jointly established the Joint Research Center for Intelligent Grinding Technology with Tsinghua University and set up a joint grinding laboratory in the Department of Mechanical Engineering of Tsinghua University. It is committed to continuous innovation and breakthroughs in the field of precision grinding equipment, solving the "bottleneck" technical problems, striving to achieve the leap from "Made in China" to "Created in China", and leading the upgrading of Chinese equipment. 4. Domestic Substitution of Self-developed Intelligent Grinding Numerical Control System Under the same mechanical structure and electrical hardware, the machining accuracy and efficiency of numerically controlled machine tools directly depend on the performance of the numerical control system. Currently, the numerical control systems of high-end numerically controlled machine tools in China still mainly rely on foreign products. High-end numerical control systems are the key "bottleneck" technologies restricting the progress of China's industrial mother machines towards the high-end market. In order to break through the "bottleneck" technical problems of numerical control systems, the company has formed a professional technical team to tackle the core technologies of the numerical control system for precision grinding equipment. It has successfully developed the Huachen HCK2000 intelligent grinding numerical control system, and the company's products equipped with this system have been delivered to customers and passed the acceptance inspection. According to the usage and feedback from customers, the self-developed numerical control system of Huachen can comprehensively improve the grinding accuracy and efficiency of the company's products, and the system performance and stability are comparable to the advanced level of similar international products. On this basis, according to the application characteristics of new products such as sub-micron high-end composite grinding series products, precision thread grinding machines, numerically controlled linear guideway grinding machines, and new ultra-precision curved (flat) surface grinding machines, the company continuously iterates and upgrades the high-speed and high-precision intelligent grinding numerical control system, and successively realizes the installation and application of the self-developed numerical control system for new products. In the newly signed equipment orders of the company in 2024, the installation rate of the self-developed intelligent grinding numerical control system exceeded 35%. 5. Advantages in Precision Intelligent Manufacturing As a high-end precision equipment manufacturing enterprise, we have accumulated more than 20 years of profound experience in the production and manufacturing of precision equipment, and have the capabilities of manufacturing and processing complete equipment and ultra-precision parts throughout the entire supply chain. The company is equipped with a constant-temperature machining center and a constant-temperature assembly workshop covering an area of over 20,000 square meters, and has more than 100 sets of various heavy, large and medium-sized professional precision machining equipment and heat treatment equipment, including advanced equipment such as a five-axis high-precision milling-turning composite horizontal machining center of BW Company in Germany, a turning-milling composite machining center of EMCO Company, a double-workbench gantry machining center of SNK Company in Japan, and a Swiss precision numerically controlled cylindrical grinder. The company attaches great importance to the construction of digital, intelligent and information-based operation and management systems. In 2018, the company introduced the advanced foreign FMS (Flexible Manufacturing System) and high-precision horizontal machining centers to establish the company's first intelligent flexible production line. In 2022, the company's self-developed FMS system was combined with large high-precision horizontal machining centers to establish the second intelligent flexible production line. This production line is currently the first flexible intelligent manufacturing production line composed of a domestically self-developed FMS system and international top large horizontal machining centers. Through data monitoring of the entire machining process, it effectively ensures production safety and part quality, and realizes digital intelligent production.
