Guide: after China's entry into WTO, the competition of China's electromechanical products in the international and domestic markets has become increasingly fierce. How to make the domestic bearing industry develop continuously in the fierce market competition, improve product quality, explore new potential markets, and increase the share and competitiveness of bearing products in the international market is the current domestic bearing
after joining the WTO, the competition of China's mechanical and electrical products in the international and domestic markets has become increasingly fierce. How to make the domestic bearing industry develop continuously in the fierce market competition, improve the quality of products with much lower production value, open up new potential markets, and increase the share and competitiveness of bearing products in the international market is an urgent problem for the domestic bearing industry at present
Japan is a powerful country in precision bearing production, leading the world in product development, design and manufacturing, process level, product quality and production equipment. In order to further understand the current situation of bearing production and market in Japan, at the invitation of the mayor of Kobe, Japan, a Chinese bearing industry delegation jointly organized by the planning and marketing department of the China Machinery Industry Federation and the machinery industry branch of the China Council for the promotion of international trade recently paid a 10 day visit to Japan, which was a complete success. The delegation was headed by songxiaogang, Deputy Secretary General of China Machinery Industry Federation, and sunzhenbin, a consultant of the planning and marketing department of China Machinery Industry Federation and a senior expert in China's bearing industry. The members of the delegation were China Bearing Industry Association, Harbin Bearing Group Company, Luoyang Bearing Group Co., Ltd., Chongqing Yangtze River bearing industry Co., Ltd., Zhejiang Xinchang Simic Bearing Co., Ltd Fujian Nan'an Bearing Co., Ltd. and other 13 units, a total of 24 people. After visiting Japanese bearing manufacturing enterprises, the members of the delegation felt deeply about the advanced production technology adopted by Japanese enterprises. After returning to China, he will soon apply some of his technologies and management methods to his own enterprises. Through the communication and exchange between the leaders of bearing enterprises of China and Japan, the trade between Chinese and Japanese enterprises was further promoted
During the visit, the members of the Delegation believed that the production and operation of Japanese bearing enterprises have the following characteristics:first, the process and equipment are advanced, and the product manufacturing level and work efficiency are both high. This experimental speed meets the requirements of the current domestic experimental speed of all conventional metal and non-metallic materials. Entering the production workshops of Japanese enterprises, rows of equipment are neatly stacked, motors roar, and there are very few operating workers in the workshops. For standard bearings with large quantities, each person is basically responsible for 1 ~ 2 production lines. A series of processing procedures, from parts loading, clamping, processing, inspection to cleaning, assembly, oiling, packaging, are completely completed by high-precision and efficient automatic equipment. Advanced processing and detection technologies, such as adaptive grinding technology, measurement technology, fault self diagnosis technology, have been widely used, thus reducing the unqualified product quality caused by human factors, and the work efficiency is very high. Another example is that there are two modes for the automatic grinding and processing line of ball bearings produced by Japanese bearing enterprises. One is the process and equipment flow of the automatic grinding and processing line. There are a total of 18 equipment in the inner and outer rings of an automatic line, and one person is responsible for two ultra automatic grinding lines. The beat of 6200 grinding super line is
4.8 seconds/piece. There are 8 automatic lines in the workshop, which are supervised by 4 people, and the monthly output is 1million sets. Another kind of automatic grinding and loading line is composed of 27 equipment, with only 2 people watching, and the monthly output is 400000 sets
second, create a professional production pattern and maintain high-quality brands. Japanese bearing enterprises mainly produce heat treatment process, grinding process and assembly process. All rough processing procedures and parts are purchased, and each kind of parts is supplied by 2-3 enterprises and companies. This specialized production pattern has created good benefits for enterprises. Labor must first take the resource-saving development path, and the productivity per person is as high as more than 3million yuan. No matter NSK or NTN is famous in the world, there is no doubt that it is because of its high quality. They always provide the highest reliability for customers' ultra-high accuracy requirements. They advocate the production standardization of global production sites. Nearly half of NSK brand ball bearings are produced in overseas factories, which can also maintain the same level of high quality as those produced in Japan. Because of this, NSK and NTN products, led by bearings, are constantly advancing with the most cutting-edge technology of the times
third, it is necessary to form a steel structure industrial cluster in Yindu District; Take HSBC management, Yongtong cast pipe and Fengbao group as the leaders to integrate the industrial structure to meet the market demand. In the process of structural adjustment, Japanese bearing enterprises have changed their market strategies and changed the way of blindly attacking into advancing and retreating. Its strategic features are: the implementation of customs, stop, merge, turn, optimize the combination. Expand the market of superior products and shrink the market of inferior products. General purpose bearings are adjusted in the direction of mass production and low cost; Multi variety and small batch bearing products are adjusted to the unit direction. Japanese enterprises generally attach importance to product development, and based on the global development strategy under the premise of economic borderless. We constantly launch our own enterprise's characteristic products, and can put forward new products that meet the requirements of the host before the host is put into operation according to the needs of users, which has won the trust of consumers all over the world
fourth, Japanese bearing enterprises pay attention to the development of manufacturing technology and process. Among the manufacturers visited by the delegation, the enterprises are highly automated production and automatic detection. However, in the production line, not all the equipment is the most advanced, and some are still the equipment of the 1960s or 1970s (some enterprises in China have eliminated these equipment), but they can be combined with the production line and ensure the product quality, which benefits from the fact that Japanese enterprises generally attach importance to the development of production technology. Most of the enterprises visited by the delegation are production plants, but the technology development departments have strong development capabilities. While paying attention to the development of new products, they also pay attention to the development and innovation of production technology and process, so as to ensure the quality of products
