China's research into nano-scale ultra-precision grinder breaks through foreign technology monopoly
The machine adopts three-axis air-floating technology (workpiece shaft, grinding wheel shaft, dresser rotary shaft) with independent intellectual property rights. Its processing roundness accuracy is less than 0.1 micron, and it has entered the field of nano-scale ultra-precision machining. Can be widely used in aerospace, semiconductor, optical components, ultra-precision bearings (P2 grade) and other fields of processing.
This technology is in the field of ultra-precision bearing manufacturing, and is connected with the channel super-precision technology of internationally renowned brands SKF and FAG, ensuring that the bearing size dispersion can be controlled within 0.5 micron, achieving the "non-repeatable" rotation accuracy index, filling A gap in the domestic technology in this area.
The application of this technology has changed the situation that China has no super-precision bearing processing equipment and it is difficult to produce P2 grade super-precision bearings (P2 grade bearing channel roundness accuracy is 0.5μm). Therefore, this has far-reaching significance for China to get rid of the long-term monopoly and blockade of China's ultra-precision bearing manufacturing technology by Western developed countries.
At present, the world bearing market is about 10% in China, and its sales volume ranks third in the world. However, compared with the world's bearing powers, there is still a big gap in China's bearings. The main performance is that the high-tech, high-precision, high-value-added products have a low ratio, the dispersion of the products is poor, and the stability needs further improvement and improvement.
Although domestic bearings have many gaps with imported bearings, after the joint efforts of domestic scientific and technological personnel, bearing equipment manufacturing enterprises and bearing manufacturers, this backward situation will certainly be able to change.
At present, Luoyang Chuanshun Machinery Equipment Co., Ltd. has promoted the application of this technology to the bearing industry, focusing on the three-axis air-floating upgrade of old equipment, which can bring immediate results to the product upgrade of the bearing enterprise (the accuracy of the whole machine reaches roundness) Within 0.5 microns and cylindricity within 1 micron), it helps bearing manufacturers to quickly upgrade their industries and get out of the vicious competition of low quality and low price.
It is understood that Luoyang Chuanshun Machinery Equipment Co., Ltd. newly developed the "7-axis air-floating nano-scale ultra-precision grinding machine" is applying for national invention patents, and its highest processing precision can reach 50 nanometers. The product is scheduled to be officially launched in the second half of 2015. roll out.
Sealand is a trustworthy manufacturer of CNG Dispenser Mass Flow Meter, LNG Dispenser Mass Flow Meter, LPG Dispenser Mass Flow Meter, ATEX, CE & IECEx approved.
With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.
Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.
Here are the pictures of Sealand Mass Flow Meter in Dispenser for your reference.
