Mini wifi
I have a  mini flap disc , I would not use ah , is not he must want to use the wireless network card before they can use , not just plug a wireless card inserted lines show that he is not an open connection , but the connection was successful but not on the net? Enter the IP address in the browser , the browser automatically pop up here? My computer is not connected to the router is the network of others , can use mini wifi ah ! Use , you can use it as a wireless card and wireless AP to use , when the wireless LAN network cable when connected to your computer's wired network card , into the management interface set about , when the wireless AP when used on a network cable connected to a router or switch , into the management interface to set about, set see instruction manual. Relatively simple. I just installed one such host. Like you, prepare for LCD TV , I was on top of the TV . Only one extension cord mouse , a PC remote control . Taobao search for mini chassis with power supply , many, best to have a 120W power supply. Note mini chassis size , recommended Liren -E Series chassis , dimensions : 190 ( W ) * 60 ( height ) * 215 ( depth ) mm. Taobao search for mini motherboard 17 * 17 , 17 * 17 mini motherboard specifications , it is best integrated cpu, because such low power consumption.
Exist in the development of China's high-speed cutting tools
At present, China's modern manufacturing required for high-precision, high efficiency, high reliability and cutting tools product and process technologies, more than 80 percent dependent on imports, China's tool industry can not meet the needs of high-speed processing of the aviation industry, mainly in the following aspects: ① the need for the development of a modern tool industry is a lack of awareness and urgency Tool enterprises in China's large and medium-sized state-owned enterprises under the conditions of the planned economy in the long-term production the monotony of standardization tool, legalistic inertia. In recent years, while foreign tool industry in rapid technological advances, but failed to recognize the needs of modern manufacturing is the "three high and one tertiary (high-precision, high-efficiency, high reliability, and specialization)" modern tool. Over the past decade, although the introduction of advanced technology and equipment, but the equipment, First, the total amount is not enough, the second is in which a large part is used in the production line of the standard tool, continue to produce the monotony of standardized tool, necessary for the development of a modern tool industry lack of awareness and urgency. ② lack of knowledge of modern tool industry "high starting point, large investment, large-scale, international" development characteristics, low input intensity, grinding wheel ,also affect the development of Insiders lack of knowledge of modern tool industry "high starting point, large investment, large-scale, international" development characteristics, resulting in low input intensity. The the tool giant on the international assets exceed OEM abound. Many billions of dollars, the less there are hundreds of millions of dollars. Tool industry in China from the structure of the industry-wide, to the formation of a small number of large and strong, the majority of small and specialized reasonable pattern. However, from the global scope, the leader of the few investment scale of 10 to 15 billion yuan is the lowest threshold. Without this input intensity, can not be built in the true sense of the modern tool industry, also failed to meet the development needs of China's modern manufacturing.DC wheel Want to be stressed is that the development of modern tools manufacturing industry is facing serious challenges to master the development of new high-performance tools and materials, new surface coating technology and tool dedicated digital manufacturing technology, the introduction of foreign advanced equipment cost of only a very costly aspect, in fact, a lot of new materials, new coating and manufacturing soft technologies are facing multinational corporations blockade must be developed and mastered. Digestion and absorption of foreign advanced technology, based on personnel training, independent innovation, establish a brand to obtain user identity, you need to have a process. Requirements of debt service in accordance with the most state-owned tools business with loans engaged in technical innovation investment, often within five years, making the tool only major inputs in a mature market, with less risk of traditional standard tool of modern hard alloy efficient tool development has been severely constrained investment system.
Grinding stainless steel should pay attention to what
Wheel dressing should be timely, coarse grinding wheel to trim coarse, fine grinding grinding wheel should always be kept sharp to avoid overheating burns. Corner on both sides of the grinding wheel after dressing allowed burr. Low surface roughness grinding, coarse fine grinding, fine grinding margin generally stay preferably 0.05 mm, can be left 0.1 mm workpiece clamping error. Grinding process must be cooled sufficiently to take away a lot of grinding heat and erosion, and to prevent the grinding wheel the blockage and workpiece surface burns. Coolant must be clean, not mixed with debris or sand, to avoid workpiece nap. The cooling liquid of the grinding of stainless steel, generally used in the cooling performance of the preferred emulsion, or containing the extreme pressure additive and a small surface tension of the cooling liquid. The flow rate is 20 ~ 40 L / min, the grinding wheel diameter is large, 80 L / min.flap wheel Stainless steel grinding allowance should take a small diameter cylindrical grinding, grinding allowance of 0.15 ~ 0.3 mm, fine grinding margin of 0.05 mm. Basically the same margin of internal grinding and cylindrical grinding. Surface grinding on a small area of ??the rigidity of good parts, the the unilateral left margin of 0.15 to 0.2 mm, poor rigidity, large area parts, unilateral stay grinding allowance 0.25 ~ 0.3 mm.
Ceramic casing and its application market analysis
The zirconia ceramic sleeve is a core member of the optical fiber adapter and components RECEPTACLE. 2000 international Kyocera (Kyocera), Toto (Toto),abrasive tools, several Japanese companies to master zirconia ceramic sleeve complete production technology, Japan has not been to our transfer zirconia ceramic sleeve technology. With domestic optical communication market development the ceramic sleeve growing demand, in order to reduce costs and increase the competitive advantage of their products, the country pay attention to the localization of the zirconia ceramic sleeve, so the "Tenth Five" national "863" zirconia ceramic sleeve massive domestic technology in high-tech development plan, "fiber ceramic ferrule connector with zirconia powder" and "Fibre for connectors support. State Key Laboratory of Shanghai Institute of Ceramics, Tsinghua University ceramic domestic units engaged in the study of zirconia sleeve. After several years of development, the domestic enterprises and research units have mastered the precision machining of ceramic zirconia powder to the casing complete production technology. The technical progress of the ceramic sleeve is mainly reflected in the substantial increase of the quality of the zirconia nano-powder and zirconia ceramic sleeve reduce breakage during use and life improved. Nano-zirconia materials used for manufacturing ceramic ferrule and sleeve has long been Japan's monopoly, Japan Tosoh Corporation and Sumitomo Osaka Cement Company production of zirconia powder with high purity, low sintering temperature, high-density, high material strength In the past, our production quality zirconia powder with a wide gap between Japanese products Friends of can not be used in the production of the ferrule and sleeve. Failed zirconia powder production ceramic ferrule or sleeve, long-term use of the product, the ferrule end face of the rough, so that the the ferrule insertion loss significantly increase; while the casing on the decline of strength due to aging, sets tube breakage. Over the past decade, China's zirconia ceramic sleeve production capacity, production technology and product quality has been a very large increase, domestic zirconia powder improving the quality of raw materials, to promote the localization of the ceramic batch and fully grasp the ferrule sets The tube full precision machining production technology, product quality has basically reached the level of Japanese products, various types of domestic ceramic casing production optical communication adapter fully meet the needs of a variety of occasions from high-end to low-end.cutting wheel
