The three-axis adopts high-quality granite with low thermal expansion coefficient, good temperature stability, resistance to effective deformation, and good rigidity. Adopting internationally advanced precision crossbeam technology to design the structure, it is lightweight, has a low center of gravity, strong rigidity, small dynamic error, and high stability. Adopting a reflective metal strip grating ruler, it has a thermal expansion coefficient similar to most workpieces, ensuring good repeatability accuracy. By adopting a high-performance three coordinate dedicated control system and professional 3D three coordinate measurement software, the reliability and anti-interference ability of the system are greatly improved, and maintenance costs are reduced.
