The processing quality of robot components directly affects the equipment's motion accuracy and service life. High-quality parts must simultaneously meet requirements such as dimensional accuracy (e.g., tolerance of critical mating surfaces ≤±0.01mm), material stability, and functional reliability. Based on the CNC machining technology system, this paper systematically elaborates on the technical paths and implementation specifications for ensuring processing quality from five dimensions: process parameter control, material standard management, equipment precision guarantee, personnel capability building, and quality improvement mechanisms.
