Premium Material Selection

• ​HT300 High-Strength Cast Iron: Combines exceptional vibration damping (damping coefficient ≥0.03) with robust tensile strength (≥300 MPa).
• ​Microstructural Integrity: Rigorously validated under ​ISO 185 standards to ensure dense graphite morphology and zero shrinkage porosity.

Advanced Process Assurance

• Stress Elimination: Multi-stage stress relief (annealing, high-frequency oscillation, natural aging) removes >99% residual stress.
• Stable Microstructure: Precision-controlled cooling rates and alloying elements (Cu, Sn) refine grain structure for uniform mechanical properties.

Built to Last in Extreme Conditions

• Multi-Layer Protective Coating: Anti-impact, corrosion-resistant, and anti-rust composite spraying technology guarantees longevity in harsh industrial environments.

Advanced Process Assurance

• Reinforced "工"-Beam Ribs: Longitudinal ribs maximize bending rigidity and load-bearing capacity for heavy-duty operations.
• ​Honeycomb Cross-Ribs: Lightweight transverse design shifts resonance frequency beyond ​200 Hz, effectively minimizing vibration-induced deformation.

Ultra-Precision Machine Bed

• Critical Surface Finishing: Guideway mounts, screw holes, and locating holes undergo precision grinding, scraping, and milling to achieve ​micron-level flatness.
• ​Seamless Assembly: Reference planes and alignment pins ensure stress-free assembly and geometric accuracy across the entire machine tool.
