Quality Inspection & Manufacturing Process：

Pre-Assembly Inspection	Precision Machining	Vibration & Natural Aging
Each machine component undergoes precise measurement of guide rail straightness and geometric accuracy. Altimeters verify linear dimensions to ensure every part meets design standards.	High-speed rough machining removes burrs and excess material, followed by fine processing for smooth, flat surfaces that ensure long-term cutting precision.	Residual internal stress is released through vibration and natural thermal cycles. This process enhances structural rigidity, stability, and dimensional accuracy of the machine bed.
Assembly Process	Welding & Structural Strength	Final Inspection & Testing
Guide rails and gear racks are installed and calibrated by skilled technicians using precision tools, ensuring smooth transmission and stable machine performance.	CO₂ shielded welding guarantees firm, defect-free joints, improving overall frame strength, durability, and cutting stability.	Dynamic performance tests check positioning accuracy, repeatability, and micro displacement precision. Interferometers compensate for any rack errors, ensuring superior cutting accuracy.
