At present, China's machine tool industry is in a period of rapid development and improvement, and has made great progress in basic technology, design and manufacturing processes, high-end technology and new function development. The development of the machine tool industry has benefited from the continuous application and promotion of new automation technology in the machine tool industry. The development and advancement of CNC machine tools are all branded with the application of automation and innovation technology.
The CNC system is the core of CNC machine tools and the brain of CNC machine tools. The faster and stronger CNC system enables CNC machine tools to have more powerful calculation and processing capabilities, enabling more complex and detailed machining. Recently, the world's leading CNC system manufacturers have introduced new CNC systems. For example, Siemens introduced the 840Dsl and 828D systems. FANUC Corporation of Japan developed a multi-channel multi-axis nano CNC for high-end composite machine tools. Mitsubishi Corporation Developed the M700V series CNC.
These newly developed CNC systems use the latest automation technology and products, all with modular, open, flexible and unified structure, providing visual interface and network integration functions, multi-channel and multiple CNC axis functions, suitable for all processes. . In addition, high-end hardware and optical fiber transmission technologies such as ultra-high-speed processors using the latest chip technology have been applied in new CNC systems, greatly improving the performance of CNC systems.
High-speed and high-precision is not only the index-controlled machine tool, the processing speed of the workpiece is higher, the precision of the produced product is higher, and the CNC machine tool is required to operate at high speed and accurately in the whole process of workpiece machining to reduce the workpiece. The time taken for preparation, processing, transshipment, storage and other aspects, comprehensively improve the production efficiency of the factory and reduce production costs. Higher precision mechanical products will bring more benefits in practical use, such as reducing friction and heat during operation, reducing energy loss, making the whole machine run more smoothly and reliably, and reducing the probability of failure. In order to achieve the goal of high speed and high precision, automation product manufacturers have increased their technical investment and development efforts, and developed more automation products for CNC machine tools, such as linear motors, electric spindles, higher line encoders, and more precision. Highly stable grating scales, etc. These automation products provide powerful support for high-speed and high-precision functions of CNC machine tools.
Today's machining is more oriented to high precision, multi-variety, small batch, low cost, short cycle and complicated processing. Composite machining is an important technical development direction of CNC machine tools. The compound function makes the CNC machine tool significantly improve the production speed of the finished product, which can greatly eliminate the transportation, clamping and waiting time during the processing of the hashing process, which greatly shortens the processing cycle and reduces the number of products in the processing workshop. The workpiece has only one clamping position on the machine tool, which reduces the machining assistance time and improves the machining accuracy of the workpiece. Obviously, multi-tasking machines require more automation products. The implementation of composite functions relies on real-time detection and intelligent judgment, data calculation, tool management and system control for workpieces and tools. Automated products and technologies such as high-sensitivity probes, high-speed processing chips, smaller sensors, and faster response sensors and actuators will find wider application on machine tools.
CNC machine tools should have and communicate with voice, graphics, video and text. Through the sharing of network information, the production planning and scheduling department can monitor the working status and processing progress of the machine tool in real time, transfer the shared information to other users of the network information, observe the processing process, statistical reports, track the production progress, view the fault alarm, and online. Diagnose and help troubleshoot. Ningxia Little Giant Company introduced the information network technology of Yamazaki Mazak Mazak Company of Japan and created the first intelligent networked machine tool manufacturing plant in China. This will be a model in the process of informationization and networking of CNC machine tools in China, and it is also the beginning and starting point of the development of informationization and networking of CNC machine tools in China.
Research and development of new technical means, improve waste recycling methods, etc., embed green requirements and indicators of environmental protection and energy conservation into CNC machine tools, so that the impact of CNC machine tools on the environment is minimized.
