620mm 3000mm D28 3D Welding Table Precision Ground Weld Flat Table Surface

The D28 3D Welding Table with Precision Ground Flat Surface is a three-dimensional flexible modular tooling platform designed for heavy industry, high-precision welding, and the assembly of complex structural components. Based on the D28 standard hole pattern and precision-ground flat surface, it combines ultra-high load capacity, three-dimensional positioning, exceptional accuracy, and long-term stability. It is a core tooling equipment for heavy-duty precision welding in fields such as engineering machinery, shipbuilding, and pressure vessels.

Flexible positioning

• 5-Sided Precision Machining: One top surface and four side surfaces are uniformly drilled with D28 holes, enabling three-dimensional positioning in X/Y/Z axes without blind spots, allowing for multi-angle clamping of complex workpieces.
• Hole System Accuracy: CNC machining ensures hole positions within ±0.03–0.05 mm, providing extremely high repeatability and consistency, suitable for high-volume precision welding.
• Modular Fixture: Compatible with D28 series three-dimensional adjustable fixtures, quick-locking pins, and positioning angle irons, allowing for tool-free, rapid changeover in 5 minutes, adaptable to hundreds of different workpieces.

Accuracy and stability

• The work surface undergoes stress relief annealing and precision grinding, completely eliminating internal stress. It remains free from deformation, warping, or sagging even under prolonged high-temperature welding and heavy loads.
• The precision-ground surface offers extremely high flatness, ensuring greater workpiece stability, reduced welding deformation, and higher dimensional consistency.
• The hole system is processed with high-precision CNC machining, guaranteeing long-term stability of hole positions, perpendicularity, and parallelism, and consistent accuracy for repeated clamping, making it suitable for high-precision mass production.

• The cast iron/thickened steel plate structure provides excellent resistance to vibration, torsion, and impact, resulting in virtually no vibration during welding and ensuring stable weld quality.
