[Without Japan's machine tools, does China really struggle?] As the cornerstone of the equipment manufacturing industry, the machine tool industry plays an important role in the modernization of the national economy. Without Japan's machine tools, does China really struggle? CNC machine tools are digital control machine tools and are automatic machine tools equipped with a program control system. According to the different performances and grades of CNC machine tools, CNC machine tools can be divided into high-end CNC machine tools, mid-range CNC machine tools, and low-end CNC machine tools. High-end CNC machine tools refer to CNC machine tools that have high-speed, precision, intelligence, compound, multi-axis linkage, network communication, and other functions. 01 Status of Domestic Machine Tools ▼ Due to the late start, at the beginning of the development of China's machine tool industry, mainly relying on imitation and introduction, compared to the more mature Germany, the United States and Japan, China's process technology is still relatively backward, it is difficult to get rid of the "low-end" embarrassment, despite having a vast The market, but in the application of machine tools in many important industries, foreign products still occupy a larger proportion. In recent years, under the drive of innovation and development, China's numerical control technology has made considerable progress. At the same time as the industrial scale has expanded, technological development has also made a lot of progress. Shenyang Machine Tool launched the world's first i5 system with network intelligence, which caused a stir in the industry. It not only optimized the performance of the machine tool, but also integrated the new network technology and supported cloud platform data acquisition and analysis, becoming a representative of domestic high-end CNC machine tools. Similarly, Guangzhou CNC, Huazhong CNC, Dalian Guangyang and other companies have continuously updated the highest level of domestic CNC technology with innovative technology, which shows that China has the world's top technology capabilities. 02 Insufficient domestic machine tools ▼ Industrialized countries such as Europe, America and Japan have successively completed the industrialization of CNC machine tools. Compared with foreign products, the gap between domestic CNC machine tools is mainly due to the high-speed, high-efficiency and precision of machine tools. The machining accuracy and positioning accuracy of many small and medium-sized machine tool companies do not convince users. Equipment maintenance Compared to foreign products, the performance of domestic products is still not good enough, and the pressure of post-maintenance is large. From the perspective of the whole life cycle, domestic products still need to be improved. The production of CNC machine tools with domestically-made machine tools has been slow to develop, with fewer varieties and low industrialization levels. The precision indicators and performance indicators have not been hardened. PS: CNC functional components include CNC system, spindle unit, CNC tool holder and turntable, ball screw pair and rolling linear guide pair, magazine and manipulator, and high-speed protection devices. They are an important part of CNC machine tools. Their level of technology, the merits of performance, and the overall social support level directly determine and influence the technical level and performance of CNC machine tools. 03 Japanese Machine Tool ▼ Japan is the third country in the world after the United States and Germany to establish a machine tool industry, a manufacturing industry, and an industrialized country. In 1889, the establishment of the iron and steel factory in Chiba, Japan, began production of the first machine tool, which was the embryonic stage of its machine tool industry. Due to the proliferation of talents, proper management, quality standards, and the most important spirit of innovation, it eventually broke through the key technical foundations and the configuration of parts. The Japanese machine tool technology has become a world-class level overnight. There are about 200 machine tool manufacturers in Japan. Some of the most famous brands include Dama Giesen Seiki, Yamazaki Mazak, Otsuka and Fanuc. In 2014, 6 of the 11 largest machine tool manufacturers in the world came from Japan. Japan FANUC controls 65% of the global market share of CNC systems. The company has been included in the Top 100 Global Innovation Companies 2011 and 2012. Many companies in the Japanese machinery industry have considerable strength. They not only have a long history, but also have deep market accumulation. For example, Japan Steel Industry Co., Ltd. was established in 1907, Yamazaki Mazak was established in 1919, Mori Seiki returned to 1948, and Fanuc was traced back to 1958. 04 postscript ▼ In recent years, the development of China's manufacturing industry has been good, and the market demand has been continuously upgraded. The transformation and upgrade of the machine tool industry is imminent. China must accelerate development to avoid being eliminated. ▲ Localization rate of different CNC machine tools After several decades of development, China's CNC machine tools industry has become the world's largest producer and seller of products. The rapid development of technology and production capacity has already provided the basis for responding to the national manufacturing transformation. In the future, the demand for CNC machine tools in China will shift from middle to low to high-end, in other words, high-end CNC. The machine tool will have a larger import substitution space. Today's China is not China 50 years ago or China 20 years ago. We already have a fairly good material, technical, and financial foundation. As long as we have the spirit of self-reliance and self-reliance, we must use the spirit of developing “two bullets and one star†and “Shenzhou spacecraft†not long ago. I believe many problems can be overcome. To let the Japanese and the Americans have less "cow" in front of the Chinese people, the key is to rely on ourselves.
Dc Gear Motor can be defined as an extension of Dc Motor which already had its Insight details demystified here. A dc gear motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a dc gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
Application field: usually used Electronic door locks, shutter motor, home audio equipment, sweep the floor machine robot
Features: dc gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Dc geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Dc geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
