Is the bismuth molybdenum bismuth alloy wire the main wire cutting electrode wire? A group of research materials will tell you later. We start with the “six hopes” of the wire cutting industry. There are so many expectations in the wire-cutting boss: one is looking forward to the wind; the second is not changing the liquid; the three expecting the meter does not turn; the fourth is expecting the rent to be halved; the five hope that the sun does…

Recently, China’s newly developed TMH20/15MN large radial precision forging machine was successfully tested at one heat load, and the first qualified high-end bar was forged. The successful test of the radial precision forging machine marks that the core manufacturing equipment of high-end pipe in China will no longer be easily “card neck”! However, this also means that China has successfully broken one of the technical barriers that have long been completely monopolized by foreign countries – large radial precision forging…

Recently, the United States is looking around for alternatives to China’s rare earths. In addition, a hurricane hit the US state of Florida, causing damage to almost half of the F-22 aircraft in the base. It seems that the “Eagle Eye” filmed by NASA is not only “eyelid” and “eyes”, but the power is also sufficient. Worse, these fighters are “invisible”, so that the current count of damage is still in progress. Up to now, there are more than 20…

You are concerned about the news that “the Chinese have broken through the Western blockade of China and won the championship for the third time”. Things are like this. Recently, the thin film optical laboratory of the Key Laboratory of Laser Materials of the Chinese Academy of Sciences, affiliated to the Shanghai Institute of Optics and Fine Mechanics (Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences) successfully developed a laser reflective film module, and for the third…

How to choose the electrode material in EDM? Is it right to find tungsten-copper composites directly? First of all, we have to know what is the main electrode material of EDM to continue to deepen. What are the main components of EDM electrode materials? The electrode materials for electric discharge machining mainly include graphite, copper and tungsten-copper composite materials. I believe that the master of mechanical machining also knows that in EDM, the physical properties of the electrode material have…

A few days ago, the US Department of Defense announced the report “Assessing and Strengthening the Flexibility of the US Manufacturing and Defense Industry Foundation and Supply Chain.” The report said that the US defense industry is heavily dependent on foreign countries and contains nearly 300 kinds of foreign military products. Among them, the demand for rare earth and other materials and spare parts in China is particularly large, such as military solar cells and aircraft LCD screens. Therefore, there…

The Similarities Between WEDM-HS, WEDM-LS and WEDM-MS WEDM-HS, WEDM-LS and WEDM-MS all refer to – EDM machine – a CNC machine tool that can remove metal and complete workpiece cutting tasks. The full name of the electric discharge wire cutting machine Wire-cut Electrical Discharge Machining，English abbreviation is WEDM. From another point of view, it can also be said that the WEDM-HS, the WEDM-MS, the WEDM-LS are all metal wire and metal discharge corrosion processing. The Differences Between WEDM-HS, WEDM-LS and…

The old driver said that this transparent car insulation film, which you may not know, is a tungsten oxide transparent car insulation film. Although, at present, there are many kinds of car films on the market, such as 3M, Weigu, Ray-Ban, etc… The old driver who has been in the film industry for a few years said that after years of research and development by researchers, they have successfully applied tungsten oxide nano-transparent thermal insulation coatings to automotive glass by…

Environmental issues have followed the rapid development of the social economy. Nowadays, environmental issues have been put on the agenda as an important issue that cannot be avoided. Therefore, we must not only pursue economic development, but also go side by side with environmental protection! Therefore, the emergence of new environmentally-friendly materials will always become a topic after people have a meal. Although it is only a topic of time, it is not very shocking and will not detonate the…
