6. Develop marketable CNC products according to market needs High-tech is a direction of the development of CNC systems. On the other hand, the development of marketable CNC products is also suitable for market development. China is a developing country, and economical CNC systems have a broad market in China. Therefore, it is very meaningful to develop a numerical control system with excellent performance and low price to meet the needs of the Chinese market. At present, China's economical CNC machine tools require about 8,000 to 10,000 units per year. Although there are dozens of manufacturers in production, the price is very cheap, but the technology development is not fast for many years, there are still some problems in performance and reliability, can not meet the market demand. SINUMERIK 802S was launched in 1997 by Siemens AG (Nanjing) Co., Ltd., a joint venture established by SIEMENS in Germany. In addition to the G code programming, this system also has a graphics loop support function, which is converted by software keys. It adopts 15.24cm (6in) color liquid crystal display and uses two stepping motors as the driving unit. The driving torque is 3.5~12N.m, and the price is about 30,000 yuan. This is Siemens' efforts to occupy the Chinese market. 7. Develop new CNC products With the development of machining technology, the performance requirements of CNC machine tools are getting higher and higher, and it is urgent to develop some new mechatronics CNC products to meet and meet these requirements. For example, the large-scale use of aluminum alloy materials requires high-speed cutting to achieve high precision and low surface roughness. The spindle speed requirements of CNC lathes and machining centers are increased to 10,000 to 20,000 r/min, which is the use of conventional machinery. The drive is difficult to achieve. Therefore, the "electric spindle" that integrates the armature of the motor directly with the spindle of the machine tool has become an urgently needed product in production. At present, Japan's FANUC company, NSK company, Switzerland's IBAG company, Italy's GANFIOR company are developing and producing this new product. Similarly, in order to achieve high-speed movement, it is required to develop a "linear motor" to directly drive the linear motion of the table. The linear motor produced by FANUC Japan can move at speeds up to 100m/min. Japan's THK, Germany's INDRAMAT and SIEMENS are developing and producing such products. In summary, the development of numerical control technology is synchronized with the development of modern computer technology and electronic technology, and is also developed according to the needs of production development. Now that CNC technology is mature, the development will be deeper, wider and faster. Future CNC systems will make machinery more usable and cheaper. Previous page
