Analysis of Development Status of China's CNC Machine Tool Industry in 2014-2015
As the strategic equipment of the national defense industry, CNC machine tools are the most important means of manufacturing all kinds of weapons and equipment and are an important guarantee for the modernization of national defense and military equipment. Many times, CNC machine tools are also called "machining centers." Since its appearance, CNC machining has brought revolutionary changes to the machinery manufacturing industry.
CNC machining machines follow fundamentally consistent process principles in many ways. However, due to the unique function of automatic tool change in NC machine tools, the NC machining process has its own features. Below the Chinese machine tool business network Xiaobian from the advantages and disadvantages of the processing center analysis of two aspects.
The advantages of CNC machine tools are mainly reflected in the following aspects:
First, the production efficiency of CNC machine tools is high. It can not only save the work of marking, intermediate inspection, etc., but also due to its automatic tool change function, usually can also save the complicated tooling, reduce the installation of the processing parts, adjustments and many times the knife is relatively complex and tedious jobs. The machining center can select the best process line and cutting amount to effectively reduce the auxiliary time in processing, thereby improving the production efficiency.
Second, the CNC machining machine has high processing precision and stable processing quality. The automatic tool change function of the machining center can very effectively reduce the number of workpieces to be mounted, reduce or eliminate the positioning error caused by multiple mountings, and improve the machining accuracy. When the position accuracy of parts of parts is high, the automatic tool change function of the machining center can be very convenient and effective to reduce the error of positioning and tool setting. It can complete all parts in one clamping and one-off tool setting. Processing to ensure the position accuracy requirements of the processing parts.
Third, CNC machine tools have strong adaptability and flexibility. On the machining center, it is easy to carry out many different machining processes such as drilling, reaming, reaming, boring, tapping, milling, and grooving of box parts. Therefore, the contours can be machined to a particularly complex shape. Hard to control the size of the parts, such as fan blades, car engine box and other parts. Can process complex curve parts and very complex 3D curved surface parts.
Fourthly, to improve economic efficiency, a CNC machine tool concentrates the functions of various equipment such as milling machines, drilling machines, tapping machines, etc. It can reduce the number of machine tools for a company, because one person can operate multiple machining centers at the same time, reducing the number of machine tools. Operating workers, labor costs will be reduced accordingly; in addition to having a CNC machining center is also a concrete manifestation of the strength of the company, which will lead to an increase in more business volume and thus increase economic efficiency.
Everything has two sides, and there are also deficiencies in CNC machine tools, which are mainly reflected in the rigidity of the fixtures of the machining centers, the rigidity of the processing centers and the maintenance of precision; the technology of machining centers is complex, and the use, maintenance, and management The requirements are relatively high; the one-time investment of the machining center is large, and other auxiliary devices such as the CNC tool system are required to be configured.
From the above two aspects, when purchasing CNC machine tools, consumers must pay attention to selecting large-scale, strong-strength, and service-guaranteed production units so that the quality of products can be guaranteed.
CNC machining machine is a highly mechatronic product, suitable for processing many varieties of small batches of parts, the structure is more complex, high precision parts, parts that need frequent modifications, expensive parts that are not allowed to be scrapped, requirements Precision-reproduced parts require urgently needed parts that shorten the production cycle as well as parts that require 100% inspection. CNC machine tools have attracted worldwide attention for their outstanding flexibility, automatic performance, excellent and stable accuracy, and agile and diverse functions. It has created a precedent for the development of mechanical products to electromechanical integration. Therefore, CNC technology has become a core technology in advanced manufacturing technology. The characteristics and application range of CNC machine tools make them an important equipment for the development of national economy and national defense construction.
In recent years, China's furniture and woodworking machinery industry has achieved rapid development. However, in the mid-to-high end product areas, domestically produced equipment still lags behind in terms of its variety, quality, reliability, delivery time, and pre-sales and after-sales service. Huge market demand. At present, China is in the process of upgrading and upgrading traditional furniture with high-tech and advanced and applicable technologies, and using information technology to enhance the competitiveness of China's furniture manufacturing industry. This is a key historical period for manufacturing and equipment informatization. It is of great significance to carry out research on the application of high-end furniture and wood processing equipment.
As a major manufacturing country, China mainly relies on comparative advantages in labor, prices, resources, etc., and there is still a wide gap between its product innovation and independent development. China's CNC machine tool industry cannot rest with the status quo. It should seize the opportunities for continuous development, strive to develop its own advanced technologies, increase technological innovation and personnel training, improve the company's comprehensive service capabilities, and strive to shorten the gap with developed countries. We will strive to realize the transition from low-end to high-end CNC machining machine products, from primary product processing to high-precision product manufacturing as soon as possible, and realize the transition from manufacturing in China to creation in China and from manufacturing to manufacturing.
