The number of ordinary machine tools in China is about 3 million units. If you calculate 60,000 yuan for each remanufacturing, it means a 180 billion yuan transformation market. Even if not every ordinary machine tool has the value of transformation, then this piece The cake is undoubtedly massive. The question is, can the domestic CNC system meet the technical specifications of machine tool remanufacturing?
Domestic systems can be competent
On June 3, China Industrial News reporter came to Sanhuan Automobile Directional Machinery Co., Ltd., located in Xianning City, Hubei Province. The company is affiliated to Hubei Sanhuan Group, with a production value of 360 million yuan last year. It is one of the "little giants" in the auto parts industry.
Minister Deng of the Equipment Management Department of Sanhuan Railway Machinery Co., Ltd. told the reporter: "Since 2004, the company began to tentatively adopt a system of Huazhong CNC for the transformation and upgrading of the second-hand machine tool of CK7815 of Great Wall Machine Tool Plant. After one year of use, we found that The Chinese medieval star numerical control system is not only suitable for teaching as legendary, and its performance is comparable to that of Siemens 802D and FANUC0imateTC. Because the domestic CNC system has the advantage of cost performance, and the company is close to Wuhan, it can easily and quickly get the Huazhong CNC. Technical support and personnel training, while using the "Chinese brain" equipment domestic machine tools, to provide a platform for display capabilities of domestic CNC systems, since 2005, our company has successively purchased a number of equipment equipped with Huazhong CNC system."
The original intention of remanufacturing is to save. Minister Deng calculated the account for the reporter. The residual value of an old ordinary thread grinder was 100,000 yuan, and the transformation cost was 100,000 yuan, totaling 200,000 yuan. The purchase of a new CNC thread grinder costs about 450,000 yuan, and remanufacturing saves more than 50% of the cost of technical renovation. For their equipment management department, the old machine tool is not the main business. When the equipment is overhauled, if they feel that there is a need for transformation, they will finish the work by the way. Even so, the team led by him last year saved the company millions of dollars in technical renovation costs, and therefore also received the company's rewards.
Re-manufacturing is not only in line with national industrial policies, but also saves costs for enterprises. Why not do it? Equipment users also have their own difficulties. The spare parts of imported equipment are very expensive. One of the reasons is that Minister Deng told reporters that a set of encoders for HEIDENHAIN would cost two or three thousand yuan. The price of a whole domestic CNC system is no different.
CNC system is the core component of CNC machine tools. Its technical level directly affects the performance quality and efficiency of CNC machine tools. It is of great significance for improving the success rate and economic benefits of CNC machine remanufacturing. Since the import system is too expensive and violates the original intention of remanufacturing, the key question remains: Can the domestic CNC system be competent?
Chen Jihong, secretary general of the CNC System Branch of China Machine Tool Industry Association, said: "There are gaps between domestic CNC systems and imported products, but they are smaller than the industry imagined. Domestic systems now sell more than 100,000 sets a year, if reliability is true. Poor, we can't save the fire."
He believes that the performance and reliability of domestic CNC systems have reached a high level. Compared with foreign products of the same grade, the domestic CNC system has a good performance-price ratio advantage, which is very suitable for CNC remanufacturing of machine tools.
At present, there are nearly 30 major manufacturers of CNC systems in China, forming the East (Shanghai Open, Nanjing Huaxing, Nanjing Xinfangda, Jiangsu Renhe), South (Guangzhou CNC, Shenzhen Shanxing), West (Chengdu Guangtai, Mianyang Sheng) Wei, North (Beijing Kai Endi, Shenyang Gaojing, Dalian Guangyang, Beijing Aerospace, Dalian Dasen, Beijing Kaiqi), China (Wuhan Huazhong CNC) layout. The development speed of these enterprises is relatively fast, and the production and sales of CNC systems are also relatively large.
The domestic economical numerical control system has developed rapidly, and it has occupied more than 95% of the domestic economical numerical control system market share, forming a scale advantage and leading the market of domestic economical numerical control systems. The function and performance of the domestic popular CNC system are continuously improved, and the price and service have great advantages, the reliability is greatly improved, and the supporting functions such as the all-digital AC servo drive system and the spindle servo drive system are available in the CNC milling machine and machining center. And other mid-range CNC machine tools get batch matching applications.
In the development of domestic high-end CNC systems, China has partially mastered the core technology of high-end CNC systems, developed some high-end CNC system products, and has been applied in military enterprises, breaking the foreign technology blockade. Therefore, the domestic popular CNC system has achieved batch matching with CNC machine tools, and the product reliability and technical performance have been gradually recognized by the end users.
In the middle and high-end market, the domestic CNC system has also achieved batch matching with equipment manufacturing enterprises. There are more than 100 five-axis CNC machine tools equipped with Huazhong CNC system, aerospace system, blue sky system and Cage system in aviation, ship and electric power. Many key enterprises in the field of automobiles and automobiles have been successfully applied, and user usage is very good. The national XK2136-5X five-axis linkage CNC gantry milling machine jointly produced by Huazhong CNC and Guilin Machine Tool was purchased by Nanchang Aircraft Manufacturing Plant of China and became the first high-end CNC machine tool selected by China's large aviation manufacturing enterprises to support the domestic five-axis linkage CNC system. Since 2002, Wuxi Shenlong Lolin Precision Machinery Co., Ltd. has ordered five five-axis CNC machine tools and a four-axis CNC milling machine equipped with Huazhong CNC system for the manufacture of large impellers and various turbochargers.
