In the past few years, China's shipbuilding industry has achieved leap-forward development and its position in the international ship market is becoming more and more important. Especially in 2008, China's shipbuilding industry not only achieved remarkable achievements in shipbuilding completion and hand-held ship orders at the end of the year, but also made breakthroughs in economic scale, economic benefits, and independent research and development.
In terms of innovation, new breakthroughs were made in the R&D and construction of high-tech ships and offshore engineering equipment: the first large-scale LNG carrier and the 10,000-ton container ship were successfully delivered; the first 3,000-meter deep-water semi-submersible drilling platform was built in China; New progress has been made in key scientific research projects such as 160,000/200,000 cubic meters of LNG vessels and self-owned brand medium-speed diesel engines.
I. Interactive development of the domestic machine tool industry and the shipbuilding industry
It should be said that the tremendous development achievements of the shipbuilding industry are closely related to the rapid and rapid development of the machine tool industry in recent years, and the two complement each other.
1. Domestic machine tool industry provides processing support
As the industrial machine of the "machine device", the domestic machine tool industry has provided a wide range of high-tech, high-performance machine tools for shipbuilding enterprises, especially marine equipment manufacturers, in order to improve the overall production capacity and production efficiency of the shipbuilding industry. Provides strong support.
In the marine industry, important components of marine diesel engines such as crankshafts, body, cylinder heads, connecting rods and camshafts, large marine propellers, rudder blades, rudder stocks, cranes, anchoring machines, separators and other marine accessories For the processing and manufacturing, all kinds of machine tools such as boring and milling machines are needed.
At present, China's machine tool industry has been able to meet most of the machine tool equipment required by the shipbuilding industry, and the high-tech content of the equipment is constantly improving. Among them, CNC lathes, turning and milling machining centers, horizontal machining centers, vertical universal grinding machines, CNC milling and boring machines, gear hobbing machines, etc., can be provided by local machine tool enterprises.
Jinan No. 2 Machine Tool Group has successfully developed the first mechanical five-axis linkage CNC machine tool with complete independent intellectual property rights. This equipment can improve the precision and smoothness of the machined surface, reduce or even eliminate the subsequent manual grinding, and is suitable for propellers. Processing.
Harbin Measuring and Cutting Tool Group has successfully manufactured China's first parallel machine tool with international leading level. This machine line can greatly reduce the number of machine tools, improve processing quality and reliability, and is suitable for free-form surface processing of large complex parts such as ships.
The “CNC Heavy Duty Crankshaft Rotary Machining Center†independently developed by Qizhong CNC Equipment Co., Ltd. has filled the domestic gap. Moreover, the first large-scale marine crankshaft machined by the machine tool has been rolled out of Qingdao Haixi Heavy Industry Co., Ltd., which has changed the long-term dependence on imports of large-scale machine tools made in China.
2. The ship industry drives the demand for machine tools
At the same time, the shipbuilding industry is the fastest growing and most active industry in the downstream industry of the machine tool industry. All related enterprises have a large demand for large machine tools such as gantry milling and boring machines, floor milling and boring machines, machining centers, grinding machines and gear processing machines. And the performance requirements are also very high, which fully promotes the rapid development of the domestic machine tool industry.
Although the current global financial crisis has brought many "troubles" to the development of the shipbuilding industry and the machine tool industry, the tasks of the world and China's shipbuilding industry will remain full in the next two to three years, which brings rare opportunities for the further development of the machine tool industry. space.
On the one hand, Chinese shipbuilding companies are full of orders, and most of the orders of enterprises have been discharged to 2011, but the development speed of marine equipment manufacturers still lags behind the development of shipbuilding industry, the production capacity of key marine supporting equipment is insufficient, and the status quo depends on imports. Did not get a fundamental change.
At present, and in the latter period, under the encouragement of the national "Shipbuilding Industry Adjustment and Revitalization Plan", China's major marine equipment manufacturers, especially medium and low-speed diesel engine manufacturers, will intensify technological transformation and promote key components such as diesel engines and diesel engine crankshafts. Localization of development. Their demand for machine tool equipment replacement and the need to add new equipment will definitely drive the machine tool industry to grow further.
On the other hand, the speed of optimization and upgrading of China's ship product structure is accelerating, and a large number of large-scale, high-tech, high-value-added ship products will be more and more. It is necessary to build these ships and marine supporting equipment efficiently and quickly. For high-end, more advanced CNC machine tools. It can be foreseen that in the future, the demand quality of the shipbuilding industry for machine tools, especially high-end CNC machine tools, will tend to be high-end, and the demand structure will tend to be rationalized.
3. The domestic machine tool industry still needs to make great efforts
Although the production capacity and technical level of China's machine tool industry have been greatly improved in recent years, there are still some high-end CNC machine tools that need to be imported from abroad.
For example, CNC gantry milling machines, CNC boring and milling machines, CNC boring machines, etc. for processing low-speed diesel engine mounts, frames, cylinder blocks, etc.; machining inner and outer cylindrical lathes and vertical honing machines for cylinder liners of low-speed diesel engines; processing low-speed diesel engine oil Horizontal turning center of head oil pump, pentahedron machining center, etc.
Moreover, because some CNC machine tools can only be produced in a few countries, the price of the products is high, and the delivery period is difficult to guarantee. Moreover, some products belong to other countries' strategic materials, and often impose restrictions and embargoes on China, which seriously affects Chinese marine use. The production capacity of equipment enterprises has increased rapidly.
Faced with the current major problems, the machine tool industry and the shipbuilding industry should strengthen close cooperation and take effective measures to promote mutual progress and achieve a win-win situation.
Second, strengthen cooperation and enhance productivity
1. Promote the localization and high-end of marine machine tools as soon as possible
In the next 5 to 8 years, it will be a crucial period for China to catch up with Japan and work hard to build a world shipbuilding power. A new round of leaping development in the shipbuilding industry urgently requires a large number of domestic high-end processing equipment. The localization and high-end level of marine machine tools are crucial to the development of the shipbuilding industry.
In the future, the machine tool industry should adhere to the principle of key breakthroughs to promote comprehensive development, further strengthen the joint design and joint manufacturing with foreign advanced technology, accelerate the pace of localization of marine high-end CNC machine tools, and vigorously develop large-scale, precision, high-speed CNC. Equipment and CNC systems and functional components.
With the gradual increase of the proportion of high-end CNC machine tools in the machine tool industry, the shipbuilding industry uses high-precision CNC machine tools to manufacture key marine products, laying a solid foundation for the large-scale, high-tech, high value-added ship construction in the future.
2. Encourage and support shipbuilding enterprises to give priority to domestic machine tools
The localization and high-end process of machine tool equipment not only requires the unremitting reform and innovation of the machine tool industry itself, but also the support and drive of the shipbuilding industry in the downstream industry.
It is necessary for the shipbuilding industry to be market-oriented, supported by policies, and adopt various effective measures to encourage and support shipbuilding industrial enterprises to give priority to domestically produced machine tools in the process of production and technological transformation.
By prioritizing the use of domestically produced machine tools, especially large-scale, high-precision CNC machine tools, there are two main advantages: First, it can improve the domestic market share of domestic machine tools, improve and improve the product quality and technical performance of domestic machine tools, for the direction of these advanced CNC machine tools. On the other hand, it can minimize the dependence of shipbuilding manufacturers on foreign high-end machine tool products, reduce the procurement costs of shipbuilding companies and avoid the delay in delivery risks that may be faced.
3. Actively develop effective communication and build cooperation platform
Effective communication and collaboration mechanisms are an integral part of the joint development of the marine industry and the machine tool industry.
This means that the shipbuilding industry and the machine tool industry should carry out more extensive exchanges and cooperation in project development and personnel training. Under the premise of the conditions, the joint research and development of marine machine tool projects will be actively carried out, and a group of relevant personnel in the shipbuilding industry enterprises will be selected to participate. At the same time, a group of personnel from the machine tool industry were also selected to learn and exercise in the shipyard and marine equipment factories.
By building a long-term and effective cooperation platform, it is not only expected to realize the direct connection of demand, but also make the product development of the machine tool industry more "targeted", thus providing more suitable products for the shipbuilding industry. At the same time, it can also cultivate the ship with effective practice. The core reserve talents of the industrial and machine tool industries lay the foundation for the sustainable development of these two industries.
