The high-precision turning and milling composite machine tool integrates multiple processes such as turning, milling, drilling, and tapping, and can complete the full sequence processing of complex parts with one clamping, greatly reducing repeated positioning errors and effectively improving product accuracy and consistency. Machine tools have high rigidity, high speed, and high dynamic response characteristics, with high processing efficiency, centralized processes, and shorter workflows. They are particularly suitable for efficient production of complex precision parts such as shafts, irregular parts, polyhedra, etc. They have significant advantages in shortening processing cycles, improving yield rates, and reducing production costs. They are ideal equipment for high-end precision manufacturing.
