How to make the domestic bearing industry develop continuously in the fierce market competition, improve product quality, open up new potential market, increase the share and competitiveness of bearing products in the international market, is an urgent problem solved by the domestic bearing industry. Japan is a strong producer of precision bearings and is among the world's leaders in product development, design and manufacturing, process level, product quality and production equipment.
In order to further understand Japanese bearing production and market status, recently, at the invitation of the mayor of Kobe, Japan, the Chinese Bearing Industry Research Group, jointly organized by the Planning and Marketing Department of China Machinery Industry Federation and the Machinery Industry Branch of China Council for the Promotion of International Trade, recently A 10-day visit to Japan was a complete success. The delegation was headed by Song Xiaogang, deputy secretary general of China Machinery Industry Federation, Sun Zhenbin, consultant of Planning and Marketing Department of China Machinery Industry Federation and senior expert of China's bearing industry. The delegation was composed of China Bearing Industry Association and Harbin Bearing Group. Luoyang Bearing Group Co., Ltd., Chongqing Changjiang Bearing Industry Co., Ltd., Zhejiang Xinchang Ximic Bearing Co., Ltd., Fujian Nan'an Bearing Co., Ltd. and other 13 units are composed of 24 people. After visiting the Japanese bearing manufacturing companies, the members of the delegation were deeply impressed by the advanced production technologies used by Japanese companies. After returning to China, some technologies and management methods will soon be applied to their own enterprises. Through the communication and exchange between the leaders of the bearing companies of China and Japan, the trade between Chinese and Japanese companies has been further promoted.
During the visit, members of the delegation believed that the production and operation of Japanese bearing companies had the following characteristics:
First, advanced technology and equipment, product manufacturing level, work efficiency is high. Into the production workshop of Japanese companies, the rows of equipment were neatly stacked, the motor roared, and there were very few operators in the workshop. For a large number of standard bearings, it is basically responsible for 1 to 2 production lines per person. From the processing of parts loading, card loading, processing, inspection to cleaning, assembly, oiling, packaging, etc., it is completely completed by high-precision and high-efficiency automation equipment, advanced processing technology, such as adaptive grinding technology, online Measurement technology and fault self-diagnosis technology have been widely used, which has reduced the quality of products caused by human factors and the work efficiency is very high. Another example is the existing two models of ball bearing grinding automatic line produced by Japanese bearing enterprises. One is the automatic line process equipment process for grinding. There are 18 sets of automatic inner and outer rings, and one person cares for two grinding super automatic lines. The 6200 grinding super line beats 4.8 seconds/piece. There are 8 automatic lines in the workshop, which are controlled by 4 people and the monthly output is 1 million sets. Another type of automatic grinding line consists of 27 sets of equipment, only 2 people are in charge, with a monthly output of 400,000 sets.
Second, create a professional production pattern and maintain a quality brand. The production of Japanese bearing companies is mainly heat treatment process, grinding process and assembly process. All roughing processes and parts are purchased out, and each component has 2 to 3 companies and companies. This specialized production pattern has created good benefits for enterprises, and the labor productivity is as high as 3 million yuan per person. Whether it is NSK or NTN, the reason why it is famous in the world is undoubtedly due to its high quality. They always report the highest reliability for their customers' high precision requirements. They promote the standardization of production at global production sites. Nearly half of the NSK brand ball bearings are produced in overseas factories, and they can maintain the same high quality as those produced in Japan. Because of this, NSK and NTN products, which are led by bearings, are constantly in sync with the most advanced technologies of the times.
Third, adjust the industrial structure to adapt to market demand. In the structural adjustment of Japanese bearing companies, they have changed their market strategies and changed their offensive behaviors. Its strategic characteristics are: implementation of closure, stop, merger, transfer, and optimization of the combination. Expand the market for superior products and shrink the market for weak products. General-purpose bearings are adjusted to high-volume, low-cost directions; multi-variety and small-volume bearing products are adjusted to the unit direction. Japanese companies generally attach importance to product development and are based on global development strategies on the premise that the economy has no borders. Constantly launching its own company's featured products, it can meet the requirements of users before the host to put forward new products to meet the requirements of the host, which has won the trust of consumers around the world.
Fourth, Japanese bearing companies focus on the development of manufacturing technology and technology. Among the manufacturers visited by the delegation, the company is highly automated production and online automatic inspection. But on the production line, not all equipment is the most advanced, some are still in the 1960s or 1970s, but they can be combined with the production line and can guarantee the quality of the products, which is due to the widespread attention of Japanese companies. Development of technology. Most of the enterprises visited by the delegation are production plants, but the technology development departments have strong development capabilities. While attaching importance to the development of new products, they also pay attention to the development and innovation of production technologies and processes to ensure the quality of products.
After visiting the delegation, the members of the delegation believed that the following production technologies could be used by domestic enterprises for reference:
1. Bearing grinding and bearing assembly automatic line technology.
2, bearing automatic line online automatic testing technology.
3. Precision steel ball manufacturing process and testing technology.
4, heat treatment production line automatic alignment technology.
5, ball bearing double end grinding machine inner and outer ring set grinding technology.
6, CBN abrasive use technology.
The members of the delegation realized through the inspection that although China has become the world's largest bearing production country after Japan, the United States and Germany in terms of total bearing production and production system, it has developed its product development capability, product quality level and production. In terms of manufacturing scale, there is still a big gap between China and the bearing production countries. Chinese enterprises should strengthen technical cooperation with Japanese companies, especially small and medium-sized enterprises, and combine the advantages of Japanese enterprises in technology, capital and management with the advantages of China's market, manpower and resources to achieve mutual benefit and common development.
In order to further promote the better development of China's bearing industry, the members of the delegation of the Ministry of Machinery Industry's Fifteen Development Plan proposed the following suggestions:
1. At present, the large enterprises in the bearing industry are not strong, the small enterprises are not specialized, and the loose state of the inter-connected enterprises is transformed into a large enterprise, a small one, and a large and small enterprise. Reasonable combination of conditions.
2. The internal organization structure of the bearing enterprise is changed from olive type to dumbbell type.
3. The capital structure of bearing enterprises has changed from the state of state-owned capital to the diversified coordinated development of public, foreign-funded and private enterprises.
4. The structure of bearing products consists of low-grade bearing products, and many ordinary bearing products are transformed into high-quality bearing products. The quality of bearing materials should be close to or reach the level of international bearing brand-name products; from the emphasis on final products, the emphasis on tangible products, and the simultaneous attention to Intermediate products, value added value.
5. Accelerate the technological progress of enterprises and improve the technological innovation capability of enterprises. The pump and valve trading network will transform the existing backward group-type production methods into line-type production methods.
6. Promote the construction of specialized production systems, increase labor productivity, and reduce production costs. Pump and valve trading network enterprises should be lean in the main body, separation and assistance; adhere to the fine machining, rough processing, finished products, and the special development direction of bearing production outside the parts.
7. Accelerate the pace of internationalization and strengthen economic and technological cooperation with foreign countries. Encourage qualified bearing companies to build factories abroad.
