The overall casting is made of high-quality cast iron, with a stable structure. After annealing and aging treatment, internal stress is eliminated. Combined with 3D dynamic finite element analysis, a strong and tough rib structure is designed to ensure high precision and stable reliability of the machinery during high-speed machining. The ball screw of the three-axis transmission adopts C3 grade double nut pair ball screw, and all screws are pre stretched for stable performance and improved axial power transmission efficiency. All slides are equipped with automatic lubrication system for centralized and superior lubrication. The three-axis adopts high-precision linear slides, which can support heavy loads with extremely low friction resistance coefficient, and have fast displacement to ensure machine positioning and processing accuracy.
