At present, the distribution pattern of CNC systems on the domestic machine tool market is basically based on foreign systems such as FANUC, Siemens, and Mitsubishi, etc.; middle-to-low-end systems are dominated by domestically-made systems, such as Guangzhou CNC and Beijing Kaiendi. Wuhan Huazhong. The long-term technological advantages of foreign numerical control systems have made high-end machining centers, drilling and milling centers, compound machine tools and other high-end equipment almost entirely optional. Under such circumstances, it will take a long way to make the domestic high-end numerical control system gain a place in the market.

Taking the domestic machine tools for gear shaping and hobbing machine tools as an example, at present, most of these machine tools use Siemens systems. However, from a technical point of view, this type of machine does not have to use Siemens systems. For example, the gear-inserting machine tool is mainly a three-axis linkage. One of the axes is set as a linear axis, and the two axes are set as a rotation axis. The upper and lower teeth insertion actions come from the spindle, and the spindle motor drives the mechanical transmission device. To sum up, the main requirements of the numerical control system for the gear cutting machine are as follows: 1 Three-axis linkage; 2 A linear axis and two rotary axes are simultaneously interpolated; 3 Macro variable programming. The domestic high-end numerical control system can basically meet the above requirements, and the price is more advantageous. For the hobbing machine tool, a four-axis CNC system is generally used. The technical feature is that the hobbing axis and the workpiece axis are rotated in a certain proportion at the same period to perform flat gear machining, or relative to the Z axis, and the workpiece axis is processed according to the spiral angle of the gear. Compensation, helical gear machining. The hobbing function has emerged as an independent function of the CNC system in foreign systems such as Siemens and Mitsubishi, or it is an additional function and an optional function. Therefore, the domestic CNC system manufacturers can fully develop or increase this function on their own systems and thus enter the application field of hobbing machine tools.

In addition, all kinds of tool grinders are also promising areas for domestic high-end CNC systems. At present, foreign CNC systems such as FANUC, Siemens, and Mitsubishi have special models or functions for grinding machines. However, compared to traditional positions such as machining centers and CNC lathes, grinders are a relatively new area, for example, crankshaft grinders, cam grinders, and grinding machines. Among them, the crankshaft grinder has high requirements on the servo performance, and try to use a large inertia servo motor to ensure the continuity and stability of the grinding action, improve the grinding accuracy and reduce the surface roughness, this, the domestic high-end systems and It is not difficult to achieve. For the grinding machine tools, due to the high configuration of the CNC system and mechanical functional components, the price of the whole machine is high at present, whether imported or domestic. As a matter of fact, the precision of products processed by grinding machines in China is not the same. Practice has proved that the servo motor configuration 17-bit resolution (131072 pulse / rev) encoder, you can meet most parts of the rotary axis indexing accuracy requirements, domestic high-end digital control system can do it. At the same time, the domestic market for grinding machine rebuilding has huge potential. Many traditional grinders, including profiling grinders and grinding machine tools, are faced with the choice of CNC transformation due to their low efficiency. Moreover, according to the practice summary in recent years, after the traditional grinders have undergone numerical control transformation, the processing quality and processing efficiency have been greatly improved. It is not an exaggeration to call it a green industry. Therefore, we must pay attention to the transformation industry of traditional grinding machines and gradually enter the field of grinding machine manufacturing. Taking the route of “encircling the cities from the countryside” is a new attempt and choice for domestic CNC system manufacturers.

In summary, the domestic high-end numerical control system in the competition with the foreign numerical control system, in order to achieve a breakthrough in market share, in addition to independence, but also to find new ways, that is, in the positive market without conceding, but also in the The side markets make a difference, so that we can gradually increase the product image of domestic high-end CNC systems and increase market share.
