The reporter learned from the 706 of the Second Academy of China Aerospace Science and Industry Corporation on December 8 that the institute has successfully developed the first information security product for ensuring CNC machining in China. It can build a security line from the outside to the inside, from the network to the CNC machine. Form a solid "bronze wall" to ensure safety.
According to reports, the product includes "HT706-CNCP CNC system terminal information security protection device" and "HT706-CISP border security dedicated gateway", which can obtain NC machining through risk analysis of network protection and data security in CNC machine tool operation. Technical measures for the protection of information security.
According to experts from the Institute, CNC machine tools, as key equipment for production and processing enterprises, are facing a variety of industrial viruses and cyber attacks. Once the protection is improperly attacked by external forces, it will lead to the risk of downtime of the CNC machine and even the entire production line. In China, the processing workshops of major military manufacturing units use a large number of high-end CNC machine tools. Statistics show that Germany's Siemens, Japan's Fanuc and other brands account for more than 95% of the market share of high-end machine control systems. Due to the large number of log files in foreign high-end machine tools, the manufacturer does not explain the specific meaning of the log. Domestic users cannot know the accurate information contained in it, which seriously threatens the processing safety of key components in key areas of China.
Therefore, ensuring the safety of CNC machining manufacturing has become an urgent problem to be solved. 706 R&D personnel said that the CNC machining protection system can break through the information bottleneck and realize the safe interconnection between DNC network and office network, which greatly facilitates the improvement of processing efficiency of various manufacturing enterprises.
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel Bright Bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
