machine tool industry is an important industrial branch of the national industrial system and the most powerful support and guarantee for aerospace, military, automotive, road, bridge, chemical and other industries. China's machine tool industry is in a period of rapid development and improvement, and has made considerable progress in basic technology, design and manufacturing technology, high-end technology and new function development. The development of automation technology is changing with each passing day, and new technologies, new products and new functions emerge in endlessly. The development and expansion of the machine tool industry benefits from the continuous and extensive application and promotion of new automation technology in the machine tool industry. The development and progress of CNC machine tools are all branded with automation innovation technology. Jiangsu Jinfa technology has built a multi-level and high-level technology research and development platform, which also reflects the development trend and direction of automation technology from another perspective

faster and stronger CNC system

CNC system is the core of CNC machine tools and the brain of CNC machine tools. The faster and stronger CNC system makes the CNC machine tools have more powerful computing and processing capabilities, and can complete more complex and refined processing. Famous CNC system manufacturers all over the world have introduced new CNC systems, such as Siemens' 840D SL and 828d systems, and Fanuc's development for high-end compounding has posed new challenges to material design; For the multi-channel and multi axis nano CNC of autonomous vehicle trunk machine tool, Mitsubishi Corporation developed m700v series CNC

these newly developed CNC systems adopt the latest automation technology and products. They all have a modular, open, flexible and unified structure, provide a visual interface and network integration function, have multi-channel and most axis control functions, and can be used in all process functions. High end hardware such as ultra-high speed processors using the latest chip technology and optical fiber transmission technology have been applied in the new CNC system, which greatly improves the performance of the CNC system

high speed and high precision CNC machine tools

high speed and high precision does not only mean that the processing speed of the workpiece by the CNC machine tool should be high and fast, and the precision of the products produced should be higher, but also requires that the CNC machine tool should run at high speed and be accurately positioned in the whole process of workpiece processing, so as to reduce the time occupied by the workpiece in various links such as preparation, processing, transportation, collection and storage, and comprehensively improve the production efficiency of the factory, The collet and stripping test fixture should be able to move and calibrate the production cost at the same time with the specimen under stress. Higher precision mechanical products will bring more benefits in practical use, such as reducing friction and heating during operation, reducing energy consumption, making the whole machine run more smoothly and reliably, reducing the probability of failure, and so on

in order to achieve the goal of high-speed and high-precision, automation product manufacturers have increased technical investment and development efforts, and developed more automation products to be applied to CNC machine tools, such as linear motors, motorized spindles, encoders with higher line numbers, grating rulers with higher precision and stability, etc. These automation products provide strong support for CNC machine tools to achieve high-speed and high-precision functions

the increasingly mature compound processing technology

today's machining tends to be high-precision, multi variety, small batch, low-cost, short cycle and complex processing. Compound processing is an important technical development direction of CNC machine tools. The composite function enables the CNC machine tool to significantly improve the production speed of the finished workpiece, greatly eliminate the transportation, clamping and waiting time in the processing process of the hash process, greatly shorten the processing cycle and reduce the number of WIP in the processing workshop. The workpiece is clamped and positioned only once on the machine tool, which not only reduces the processing auxiliary time, but also improves the processing accuracy of the workpiece

obviously, compound processing machine tools have higher requirements for automatic products. The realization of composite function depends on the real-time detection and intelligent judgment of workpiece and tool, data calculation, tool management and system control. Automatic products and technologies such as high-sensitivity probes, high-speed processing chips, sensors and actuators with smaller volume and faster response speed will be more widely used in machine tools

the informatization of CNC machine tools is developing rapidly

at present, automation products with networking function are widely used in CNC machine tools, which is also one of the driving forces for the rapid development of automation products and technology. CNC system manufacturers have integrated network interfaces in the system to meet and adapt to the requirements of rapid, informatization and networking of production and processing, and domestic users using informatization and networking machine tools are also gaining huge benefits

therefore, CNC machine tools should have and realize the communication functions of 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, transmit the shared information to other departments using the network information, observe the processing process, statistical reports, track the production progress, view the fault alarm, diagnose and help eliminate the fault on the network. Ningxia little giant company introduced Mazak's information network technology and established the first intelligent networked machine tool manufacturing plant in China. This will be a model in the information, information and networking process of CNC machine tools in China, and it will also be the beginning and starting point of the informatization and networking development of CNC machine tools in China

the concept of environmental protection and energy conservation is more in-depth

at present, green economy and low-carbon economy are being advocated all over the world. Such development trends and environmental protection requirements have also been responded to and practiced in the CNC machine tool industry. The so-called green machine tool requires that the manufacturing materials of the machine tool should be environmentally friendly and recyclable; It can reduce idling power and reduce power loss; Try to reduce all kinds of wastes generated during the use of machine tools and workpiece processing, and ensure that these wastes do not pollute the working environment and natural environment

according to their research results, manufacturers of automation products, CNC systems and CNC machine tools adopt new environmental protection materials and production processes, change product structures and methods, develop new technical means, improve waste recycling methods, etc., and embed green requirements and indicators of environmental protection and energy conservation into CNC machine tools, so as to minimize the impact of CNC machine tools on the environment
