At present, the commonly used machining methods include CNC computer gong processing, large-scale CNC lathe processing, large-scale CNC gantry milling processing, large-scale boring machine processing, large-scale grinding machine processing, and large-scale planer processing. Due to the stable processing quality, high machining accuracy, high repeatability of large-scale CNC lathes, and the ability to process complex surfaces that are difficult to process by conventional methods, today's large-scale CNC lathe processing may have become the vane of machining trends.

1. With the progress of large-scale CNC lathe processing technology, composite processing technology is becoming more and more mature, including milling-turning composite, turning-milling composite, turning-boring-drilling-gear machining and other composites, turning-grinding composite processing, forming composite processing, special composite processing etc., the precision and efficiency of composite machining will be greatly improved.

2. There have been new breakthroughs in the intelligent technology of large-scale CNC lathe processing, which has been more reflected in the performance of the CNC system. Functions such as automatic adjustment of interference and anti-collision function, workpiece automatically exiting the safe zone after power failure, power-off protection function, processing parts detection and automatic compensation learning function, intelligent parameter selection function of high-precision processing parts, and automatic elimination of machine vibration during processing have entered practical use. In the stage of transformation, intelligence improves the function and quality of machine tools.

3. There has been a new progress in the precision machining technology of large CNC lathes. The machining accuracy of CNC metal cutting machine tools has been improved from the original wire level to micron level. The fully closed-loop control and dynamic error compensation technology such as temperature and vibration can improve the geometric accuracy of machine tool processing, reduce shape and position errors, surface roughness, etc., thus entering the era of sub-micron and nano-level super-finishing.

4. The performance of functional components of large CNC lathes has been continuously improved, and functional components have continued to develop in the direction of high speed, high precision, high power and intelligence, and have achieved mature applications.
