1. CNC machine tools continue to develop rapidly with new structure and high performance <br> Machine tools are not only an important equipment for implementing advanced manufacturing technology, but also an important carrier for manufacturing information integration. Therefore, the development and innovation of machine tools reflect processing technology to a certain extent. The main trend. The flexible manufacturing technology centered on numerical control technology formed in the 1970s will continue to develop and become the mainstream of processing technology development in this century. Focusing on the overall technical goal of high-speed, high-precision and high-efficiency flexible CNC machine tools, the current CNC machine tools are mainly moving along the following five aspects: Note: The medium-sized machining center includes production vertical machining centers and horizontal machining centers. Its main specifications are: 2. Develop an open platform system, build a new generation of CNC systems The technical development characteristics of CNC machine tools and their constituent manufacturing systems can be summarized as 3F, 3I and 3S, namely: Led Makeup Mirror,Led Plastic Mirror Lamp,Over Mirror Light,Frost Glass Mirror Light NINGBO EASTKEY ILLUMINATE APPLIANCE CO.,LTD , https://www.eastkeylighting.com
(1) Taking the development of high-speed cutting as the forerunner, and paying attention to the speed increase of the air-running process, we strive to reduce the cutting time and auxiliary working hours in a comprehensive manner.
(2) Efficient Machining While focusing on improving the material removal rate of machine tools, we will vigorously promote the composite processing technology aiming at shortening the process chain. The process concentration is further realized by the compound numerical control machine tool, which can reduce the time for multiple loading and unloading adjustment of the workpiece, and can eliminate the time for storing and transferring the in-process product which is generated by processing on multiple machine tools according to the process, which is to improve the single piece small time. An effective way of batch productivity.
(3) For the large-scale production, the flexible production lines with CNC machine tools as the core are still the main development direction. The manufacturing systems built with the support of Reconfigurable Manufacturing technology are characterized by high efficiency and flexibility. Through the rapid reorganization of the manufacturing system, it is more agile and economical to adapt to the uncertain market demand for products, and to ensure that the products required by the market can be put into production quickly.
(4) The working accuracy of CNC machine tools is increasing by 8% to 10% per year (doubled in about 8 to 10 years), moving toward sub-micron precision, and continuously expanding new precision machining methods.
(5) The green design and manufacture of machine tools is focused on reducing environmental pollution. The efficient machining technology of dry cutting or micro-cutting fluid (≤100ml/h) is becoming more and more mature, and the development of machine tool structure is adapted.
