Machine Structure
An all-steel welded structure is used to build the machine frame, which also includes the bed and moving beam. Its symmetrical design keeps the weight evenly balanced on both sides of the column. A stable support is provided by reinforced internal ribs and a well-proportioned connection between the main drive housing and columns. The overall structure is optimized through finite element analysis to ensure sufficient strength, rigidity, and long-term stability. To prevent deformation after machining, the frame undergoes full annealing to eliminate internal stress, followed by one-time precision machining using large five-face machining centers, ensuring high geometric accuracy and consistent long-term performance.
