Honing pipe industry actively promotes technological progress, product innovation, energy conservation and emission reduction. In the first 11 months of 2009, the energy consumption and sulphur dioxide emissions of the honing tube industry decreased. With the influx of a large number of products, the supply of stainless steel honing tube market is far greater than the demand. The price keeps falling, which makes many experts in the industry short of the honing tube price. The industry expansion impulse gradually stops as the market price drops. In the view of the industry, the development of the honing tube industry should be deeply reformed and directly cut in. Substantive issues to remove key issues.
Honing tube is a honing head made of 4~6 sand bars for finishing the inner hole. Stainless steel basket company reminds: honing not only high productivity, but also high machining accuracy, general dimensional accuracy can reach IT5-IT6, surface roughness can reach 0.8-0.1 micron, and can correct the geometric deviation of the hole. In order to further improve the honing productivity, the honing technology is developing towards the direction of strong honing, automatic honing with automatic size control, electrolytic honing and ultrasonic honing. The working pressure of honing machine oil stone has great influence on honing cutting performance, which directly affects cutting efficiency, honing oil stone wear and workpiece precision and roughness. Stainless steel basket company reminds: when the working pressure of honing is high, the honing cutting amount and the abrasion amount of honing oil stone are large, and the machining accuracy and surface roughness are also poor. When the working pressure of honing is small, the cutting amount and the wear amount of honing oil stone are small, and the machining precision and surface roughness are good.
The development of precision honing tube and other industries can be described by lip and tooth dependence, so the overall level of honing tube is closely related to the development of related industries. At present, China's precision cold-drawn pipe products are mainly low-grade, low technology content, high-grade precision cold-drawn pipe mostly rely on imports, one reason is the lack of core technology in related industries. The export of precision honing tubes is increasing, and the international competitiveness level has also been improved. However, most of them are concentrated in the middle and low-grade areas. The technology level of precision honing pipes is low, and the added value is low. Some high-precision honing pipes still depend on imports. Therefore, China's precision cold-drawn pipe manufacturing industry should strengthen integration in its own field, there is no need for excessive competition, the division of labor and cooperation in technological development, the relevant industries and enterprises should take a long-term view, concentrate on new technology and new process research, and gradually form a division of labor, cooperation, multi-field, all-round. The research and development pattern has introduced the precision cold drawn tube products with independent intellectual property rights.
At present, most of the high-grade precision cold-drawn pipes rely on imports, one of the reasons is the lack of core technology in related industries. Although the export of precision cold drawn tubes has increased continuously in recent years, the level of international competitiveness has also improved. However, most of them are concentrated in middle and low-grade fields. The technology level of precision cold-drawn pipes is on the low side, and the added value is on the low side. Some high-precision cold-drawn pipes still depend on imports. Therefore, the domestic precision cold-drawn pipes manufacturing industry should strengthen integration in its own field, there is no need for excessive competition, division of labor and cooperation in technology development, related industries and so on. Enterprises should take a long-term view, concentrate on new technology and new technology research, gradually form a division of labor, cooperation, multi-field, all-round scientific and Technological Development pattern, and launch a precise cold-drawn pipe products with independent intellectual property rights. In the process of research, we can do some forward-looking research on the basis of the accumulated experience of developed countries, without burying ourselves in doing some technical work already done by others, resulting in the waste of talents and resources.
