First, the machine tool composite technology to further expand with the progress of CNC machine tool technology, composite machining technology is becoming increasingly mature, including milling - turning composite, milling composite, turning - boring - drilling - gear processing and other composite, grinding composite, forming composite processing, special composite processing, etc., precision machining efficiency greatly improved.
Second, the intelligent technology of CNC machine tools have new breakthroughs in the performance of the CNC system has been more reflected. Such as: automatic adjustment of interference anti-collision function, power failure after the workpiece automatically exit the safety zone power failure protection function, processing parts detection and automatic compensation learning function, intelligent enhance the function and quality of the machine tool. More five-axis linkage high-speed machining center was introduced.
Third, the robot makes the flexible combination of higher efficiency robot and host of flexible combination is widely used, making the flexible line more flexible, further expand the function, flexible line to further shorten, higher efficiency. Robots and machining centers, turning and milling machine tools, grinding machines, gear processing machine tools, tool grinders, electrical processing machine tools, saws, stamping machine tools, laser processing machine tools, water cutting machine tools and other forms of flexible units and flexible production lines have begun to apply.
Fourth, precision mechanical parts processing technology has made new progress in CNC gold cutting machine tool processing accuracy has been upgraded from the original silk level to the current micron level, some varieties have reached about 0.0μm. Ultra-precision CNC machine tools for micro cutting and grinding, precision can be stable to 0.0μm or so, the shape accuracy of up to 0.0'μm or so. The use of light, electricity, chemical and other energy sources of special processing accuracy can reach the nanometer level. Through the optimization of machine tool structure design, machine tool components of ultra-precision machining and precision assembly, the use of high-precision full dead cycle control and temperature, vibration and other dynamic error compensation technology, thus entering the era of sub-micron, nano-level ultra-precision machining. Functional components continue to improve the performance of functional components continue to high speed, high precision, high power and intelligent direction, and to achieve mature applications. Full digital AC servo motors and drives, high technology content of electric spindle, torque motor, linear motor, high-performance linear rolling components, high-precision spindle units and other functional components to promote the application, greatly improve the technical level of CNC machine tools.
