CNC turning is mainly used to process workpieces of revolving bodies, but sometimes it is also possible to clamp workpieces by customizing fixtures to process non-revolving products, such as planes, grooves, etc. Compared with manual turning and automatic turning, CNC turning has the characteristics of high efficiency and high precision. Moreover, with the development of science and technology, the requirements for workpieces are getting higher and higher, and more complex and higher precision workpieces need to be processed. In order to deal with such workpieces, multi-axis linkage CNC lathes have appeared, and multi-axis linkage turning machining usage is becoming more and more common.
SCZY has multiple three-axis CNC lathes, as well as multiple 4-axis linkage and 5-axis linkage CNC lathes, we can process complex-shaped rotating parts, usually the tolerance can reach ±0.01mm (specifically, it depends on the product material and structure. ), if we need better precision requirements, we can cooperate with the grinding machine for finishing, which can achieve a high precision of ±0.002mm. Our processing range includes the processing of stainless steel, alloy steel, special steel, ordinary steel, aluminum, copper, plastic and so on. Here are some CNC turning products we have processed:

In recent years, the rapid development of China's bearing industry, the bearing market is gradually optimistic, which led to an increase in the demand for bearing steel, bearing steel has become a bright spot in the domestic steel market.
According to statistics from the China Bearing Industry Association on 116 enterprises and major enterprises in the national bearing industry, from January to May this year, 107 companies produced a total of 498.4 million sets of bearings, an increase of 10.51% over the same period of last year; the sales volume of bearing products was 483 million sets. , an increase of 7.99%; bearing export sales of 185 million units, an increase of 4.55%; total industrial output value of 7.6344 billion yuan, an increase of 25.64% over the same period last year; industrial added value of 2.357 billion yuan, an increase of 20.91%. At present, China has become one of the largest bearing producers in the world.
According to the analysis of industry insiders, China’s bearing market is huge, especially the rapid development of the domestic host industry, which will provide a larger market space for the development of the bearing industry. Last year, all industries of the machinery industry maintained a rapid development trend. For example, construction machinery, heavy mining, agricultural machinery, instrumentation, machine tools, and other machinery industries all experienced large increases, with some growth rates exceeding 28%. In the first half of this year, the added value of the machinery industry increased by 27.3% over the same period of the previous year. Among them, the average increase rate of CNC machine tools, forklifts, shovel transportation machinery, power generation equipment, smelting equipment, and metal rolling equipment was above 50%; the export of machinery products. The total amount increased by 46% year-on-year. As a result, the needs of the bearing are pulled. In addition, the demand for electromechanical bearings required by a group of national key projects such as West-East Gas Transmission, West-East Electricity Transmission, South-to-North Water Diversion, the Three Gorges on the Yangtze River, the 2008 Beijing Olympics, and the 2010 Shanghai World Expo will create a huge platform for the bearing market.
The continuous expansion of the bearing market has also brought the market and business opportunities for bearing steel. Shanghai Baosteel Group's five steel company is one of the domestic bearing steel production bases. In the past few years, the production and sales of bearing steel have been booming. Last year, five steels developed high-quality bearing steels, such as automobiles, trucks, and speed-raised passenger car bearing steels. The production of new bearing steels increased by 23.8% over the previous year. In the first half of this year, the company's bearing steel production has reached 78,000 tons, an increase of 35.3% year-on-year. The newly-developed ultra-pure bearing steel cold drawing material provides the world's largest miniature bearing production company, Japan Minebea Corporation, for the manufacture of high-speed silent bearing steel for air-conditioners and is highly praised by users. The high-grade bearing steel produced by Jiangyin Xingcheng Special Steel Co., Ltd. has an annual sales volume of 300,000 tons, accounting for one-third of the domestic consumption, and has become the third largest bearing steel manufacturer in the world.
The future domestic bearing market will continue to expand. According to expert analysis, China will produce 3 billion sets of bearings by 2005, and the total industrial output value will reach 31 billion yuan. At present, China has already had 24-25 million sets of production capacity, of which universal bearings exceed supply. During the "Tenth Five-Year Plan" period, the supporting hosts for the bearings are automobiles, motorcycles, home appliances, tractors, railway vehicles, metallurgy and mining machinery, petrochemical machinery and textile machinery. China's bearing export prospects are promising. It is expected that exports will reach 1.8 billion units in 2005 and foreign exchange will reach 910 million US dollars. As a result, the demand for bearing steel will increase significantly. It is predicted that the domestic consumption of bearing steel in 2005 will reach 1.2 million tons, which is at least 20% higher than the current.
However, due to the increasingly high requirements on the quality, noise and service life of bearings in the future, the bearing industry also puts higher requirements on bearing steels. For example, precision bearings for machine tool spindles, aerospace precision bearings, bearings for computers and video recorders, etc., have high demands on bearings. However, the actual quality of the domestically-made bearing steel is still unstable, which affects the noise and life indicators and performance of the bearing. As a result, the inherent quality and surface quality of domestically-made bearings are significantly different from those of developed countries. To this end, some domestic steel mills are further developing scientific and technological research activities to meet the needs of the bearing market. On the basis of optimizing the quality of smelting, Wugang Company carries out research on the technology of stripping of silver-brilliant steel and the analysis and quality control of surface defects of bars, researches and develops high-quality bearing steels, and develops high-tech and reliable railway locomotive bearings and passengers. The steel for truck bearings is adapted to the requirements of the speed increase of passenger cars.
