CNC Automotive partsHigh speed, precision, composite, intelligent, and green are the overall trends in the development of CNC machine tool technology, achieving gratifying results in practicality and industrialization. Mainly manifested in:
1. With the advancement of CNC machine tool technology, composite processing technology is becoming increasingly mature, including milling turning composite, turning milling composite, turning boring drilling gear processing, turning grinding composite, forming composite processing, special composite processing, etc. The accuracy and efficiency of composite processing are greatly improved. The concepts of "one machine tool is a processing plant" and "one clamping, complete processing" are being accepted by more people, and the development of composite processing machine tools is showing a diversified trend.
2. The intelligent technology of CNC machine tools has made new breakthroughs, which have been more reflected in the performance of CNC systems. For example, the automatic adjustment of interference and collision prevention function, the automatic exit of the workpiece from the safety zone after power failure protection function, the detection and automatic compensation learning function of machining parts, the intelligent parameter selection function of high-precision machining parts, and the automatic elimination of machine tool vibration during the machining process have entered the practical stage, and the intelligence has improved the function and quality of the machine tool.
3. Robots make flexible combination more efficient. The flexible combination of robots and hosts has been widely used, making flexible lines more flexible, expanding functions, shortening flexible lines, and achieving higher efficiency. Robots and machining centers, turning and milling composite machine tools, grinders, gear processing machines, tool grinders, electrical machining machines, sawing machines, stamping machines, laser processing machines, water cutting machines, and other forms of flexible units and flexible production lines have begun to be applied.
4. New progress has been made in precision machining technology. The machining accuracy of CNC metal cutting machines has been improved from the original wire level (0.01mm) to the micrometer level (0.001mm), and some varieties have reached 0.05 μ About m. The micro cutting and grinding processing of ultra precision CNC machine tools can achieve a stable accuracy of 0.05 μ About m, with a shape accuracy of up to 0.01 μ About m. The precision of special processing using energy sources such as light, electricity, and chemistry can reach the nanometer level (0.001 μ m) . By optimizing the design of machine tool structures, ultra precision machining and assembly of machine tool components, adopting high-precision full closed-loop control and dynamic error compensation technologies such as temperature and vibration, the geometric accuracy of machine tool machining is improved, and shape and position errors, surface roughness, etc. are reduced, thus entering the era of sub micron and nano level ultra precision machining.
5. The performance of functional components is constantly improving, and they are developing towards high speed, high precision, high power, and intelligence, and have achieved mature applications. The promotion and application of fully digital AC servo motors and drive devices, high-tech electric spindles, torque motors, linear motors, high-performance linear rolling components, high-precision spindle units and other functional components greatly improve the technical level of CNC machine tools.
