Machine tool keeping up with the development of the times

Machine tool keeping up with the development of the times China's machine tool industry has grown from the large-scale production of small machine tools, to large- and medium-sized machine tools, and the proportion of finished products has gradually increased. The media pointed out that with the continuous improvement of the processing technology, the requirements for the processing accuracy of processing accuracy are also increasing. At present, there are tens of thousands of manufacturers in the machine tool industry in the country, most of which are based on the production of medium- and low-end rough machining.

However, due to the soaring prices of materials and energy in recent years, the monetary tightening policies adopted by the country and other factors will lead to a slowdown in the growth rate of the downstream industries and a decrease in profits. While the growth of high value-added products will continue to increase production, profits will increase substantially, and future industry competition will inevitably shift to the high-end market.

Therefore, more and more companies have begun to realize that while China's machine tool industry is sticking to the low-end sector, it should expand its development and manufacturing of high-end products rather than relying more on imported equipment.

According to different equipments, the machine tool industry uses a wide range of electrical products, ranging from single-chip microcomputers, PLCs, positioning modules, numerical control systems to motion control systems, etc., and more independent research and development of electrical equipment. Some high-end applications, such as high-precision grinding machines, rotary tool magazines, servo-stamping feeders, automated special-purpose machine assembly lines, etc., have special requirements for control and process. These are not ordinary impulse generation products or positioning products that can easily correspond to each other. , More and more are using motion control products.

Recently a new machine tool milling tool technology has saved about 20% of power consumption and increased cutting depth. When machining large parts such as steel or engine blocks, efficient milling cutters are required. When roughing the surface of the blank, it is necessary to shorten the time as much as possible. Therefore, it is beneficial to the operator to increase the depth of cut. At the same time, the power consumption of the machine tool should be as low

CERATIZIT's latest MaxiMill 27117 cutter fully meets these requirements. The maximum depth of cut can reach 8.4mm, which can adapt to the processing of steel, stainless steel, and cast iron. The CERATIZIT R&D center has developed a great deal of cutting edges in the development of this tool. This tool has a double positive angle design to ensure the process is very smooth. For the operator, this means that the MaxiMill 27117 has reduced its power consumption by 20% compared to cutting cutters of the same depth in the past. In addition, up to 8 corners per blade are economical and can benefit customers.

The latest statistics show that in 2012, Japan's machine tool equipment orders amounted to 1.2 trillion yen, a significant year-on-year decline. According to the analysis, the main reason is that, on the one hand, the orders for China have been greatly reduced. On the other hand, due to the European debt crisis, the decline in equipment investment and the appreciation of the yen have contributed to the decline in international competitiveness. Not only Europe but also China has emerged as an outflow of orders.

At present, both domestic orders and overseas orders in Japan have fallen by more than 20%. The decreasing trend of orders has become more and more obvious. The foundry industry and the machine tool industry are closely related. The two industries are closely related to one another, and are both prosperous and lossless. The ever-decreasing orders in the machine tool industry mean that the size of the machine tool industry is continuously shrinking, and the corresponding demand for foundry products will be reduced accordingly. The machine tool industry is a major market player in the foundry industry, and its continuous decline in industry performance indicates that the development prospects of the foundry industry will be hindered.

However, this situation will change in 2013. According to the data from the Japan Machine Tool Industry Association, although the reduction in orders began in the second half of 2012, as the Chinese market recovers and demand in new areas increases. In 2013, the orders for machine tool equipment will remain at least 2012 levels. Yokoyama Motohiko, president of the Japan Machine Tool Industry Association, said that the machine tool equipment orders in 2013 will maintain a level of at least 1.2 trillion yen in 2012, with a focus on breakthroughs in energy development. For new markets such as aircraft equipment, the expected amount of orders in 2013 is expected to be 1.3 trillion yen.

Affected by this, its foundry industry will also stop its declining performance, and its performance will be stable under the relevant market environment. However, if it wants to revert to a higher rate of growth, it will still need to wait for the opportunity.

Although Japan’s large manufacturing industries were generally pessimistic about the business climate, relevant data showed that at least in the machine tool industry, Japan’s order volume in 2013 was affected by rising demand from the Chinese machine tool market, and its order volume was at least 2012 levels.

A few days ago, the Japan Machine Tool Industry Association stated that the annual orders for Japanese machine tools in 2012 were around 1.2 trillion yen, with an average monthly order of 100 billion yen. In spite of the reduction in orders that began in the second half of 2012, with the recovery of demand in the Chinese market and the increase in demand in new areas, the orders for machine tool equipment will remain at least 2012 levels in 2013.

With the recent decline in the yen exchange rate and the effect of Abe's new economic policy, the sales of Japanese machine tools will improve. In addition, the passage of the U.S. government’s new budget temporarily eased the financial crisis, and orders for the automobile and aircraft-related industries will also improve. At present, China, the world's largest machine tool importer, is expected to look forward to its orders due to the rebound in the market.

Yokoyama Motohiko, president of the Japan Machine Tool Industry Association, said that in 2013 Japan's machine tool equipment orders will at least maintain the level of 1.2 trillion yen in 2012, and it is necessary to focus on breakthroughs in new fields such as energy development and aircraft equipment, and the amount of orders in 2013 is expected. The highest is 1.3 trillion yen, which is 100 billion yen higher than 2012.

Of course, this is only the expected situation. In 2012, Sino-Japanese relations have become increasingly complex, bringing a lot of uncertainties to the 2013 bilateral trade.

General Purpose VRLA AGM Battery

The now-widely used valve-controlled lead-acid battery (VRLA) uses AGM (absorptive glass mate) as its partition (hereafter called AGM Battery). The sulfuric acid electrolyte of the battery is absorbed in the AGM separator and positive and negative plates, and the sulfuric acid electrolyte of the colloidal VRLA Battery is fixed in the GEL of silica (hereinafter referred to as gel cell).

The electrolyte of AGM battery is fixed in the micropores of fine glass fiber felt, and there is no free flowing electrolyte in the battery. During overcharging, the oxygen generated by the positive electrode reaches the negative electrode through the pore channel in the AGM, and oxygen recombination reaction occurs to complete the closed oxygen cycle (the silica GEL of GEL battery will form fine cracks in the use of the battery, and become the pore channel for oxygen to reach the negative electrode ).

AGM batteries are suitable for floating charging and are often used in UPS that require high power output. This type of battery has a service life of about 5-10 years and a cycle life of about 200-500 times (80%D0D). The end of battery life often shows the increase of internal resistance, and the negative sulfation is an important cause of battery failure. At present, the vast majority of electric bicycles in China use AGM batteries as power, with a lifespan of about 1-2 years.
