Group 1 - The core viewpoint of the article highlights the significant product structure differences between Qiaofeng Intelligent (乔锋智能) and Huachen Equipment (华辰装备), despite both companies being categorized under the "C34 General Equipment Manufacturing" industry, specifically "C3421 Metal Cutting Machine Tool Manufacturing" [1] - Qiaofeng Intelligent primarily focuses on vertical machining centers, gantry machining centers, and horizontal machining centers, along with some CNC lathes and CNC grinding machines (mainly surface and guideway grinding) [1] - Huachen Equipment's core product is the fully automatic CNC roller grinding machine, which indicates a distinct specialization compared to Qiaofeng Intelligent's offerings [1]
