Composite machining of CNC machine tools

At present, China's machine tool industry is in a period of rapid development and improvement. It has made great strides in basic technologies, design and manufacturing processes, high-end technologies, and development of new functions. The development and growth of the machine tool industry benefits from the continuous application and promotion of new automation technologies in the machine tool industry. The development and progress of CNC machine tools are all accompanied by the imprint of automated and innovative technology applications.

The CNC system is the core of CNC machine tools and the brain of CNC machine tools. The faster and stronger CNC system allows CNC machine tools to have more powerful computing and processing capabilities, and can complete more complex and sophisticated processing. Recently, world-renowned CNC system manufacturers have introduced new CNC systems. For example, Siemens has introduced the 840Dsl and 828D systems. FANUC Corporation of Japan has developed multi-channel multi-axis nano-CNCs for high-end composite machine tools. Mitsubishi Developed the M700V series CNC.

These newly developed CNC systems are equipped with the latest automation technologies and products. They all have a modular, open, flexible and unified structure, provide a visual interface and network integration functions, and have multi-channel and multi-numerical axis functions, applicable to all processes. . In addition, high-end hardware and optical fiber transmission technologies, such as ultra-high-speed processors using the latest chip technologies, have been applied in new types of numerical control systems, greatly improving the performance of numerical control systems.

High-speed high-precision is not just an index-controlled machine. The processing speed of the machine tool is faster and faster. The precision of the manufactured product is higher. It also requires the CNC machine tool to operate at a high speed during the entire processing of the workpiece and precisely position it to reduce the number of workpieces. The time taken for preparation, processing, transshipment, storage, etc., will increase the production efficiency of the plant and reduce the production cost. More high-precision mechanical products will bring more benefits in practical use, such as reducing friction and heat during operation, reducing energy consumption, making the whole machine run more smoothly and reliably, and reducing the chance of failure. In order to achieve high-speed, high-precision goals, automation product manufacturers have increased their investment in technology and development, and developed more automated products for use in CNC machine tools, such as linear motors, motorized spindles, higher-line-count encoders, and improved accuracy. High and stable grating scales, these automation products provide powerful support for CNC machine tools to achieve high-speed and high-precision functions. Today's machining processes tend to be more precise, multi-variety, small-batch, low-cost, short-cycle, and complex machining. Composite machining is an important technological development direction of CNC machine tools. The composite function enables the CNC machine tool to significantly increase the production speed of the finished product, and can greatly eliminate the transportation, set-up and waiting time during the processing of the hashing process, greatly shortening the processing cycle and reducing the number of work products in the processing workshop. The workpiece only has one clamping position on the machine tool, which reduces the processing auxiliary time and improves the machining accuracy of the workpiece. Obviously, the requirements for automation products for composite machine tools are even higher. The realization of compound functions depends on real-time detection and intelligent judgment, data calculation, tool management and system control for workpieces and tools. High-sensitivity probes, high-speed processing chips, smaller-size, faster-response sensors and actuators and other automation products and technologies will be used more widely on machine tools.

CNC machine tools should have and implement voice, graphics, video and text communication capabilities. Through the sharing of network information, the production planning and dispatching department can monitor the working status and processing progress of the machine tool in real time, transfer shared information to other use departments of network information, observe the processing process, statistical reports on the network, track production progress, view fault alarms, and online Diagnosis and help troubleshoot. Ningxia Little Giant Company introduced the information network technology of Japan's Yamazaki Mazak Mazak Company and established China's first intelligent networked machine tool manufacturing plant. This will be a model for our country in the process of informationization and networking of CNC machine tools, and also the beginning and starting point for the development of CNC machine tools in China.

Research and development of new technical means, improvement of waste recycling methods, etc., embed the environmental protection and energy saving green requirements and indicators into CNC machine tools so as to minimize the impact of the CNC machine tools on the environment.
