High quality and long lasting standard D16 3D welding table

The high-quality, durable standard D16 3D welding table is a modular, high-precision welding fixture platform featuring a D16 hole system (Φ16mm holes on a 50×50mm grid). Designed for precision positioning, flexible clamping, and long-lasting durability, it is ideally suited for the precision welding and assembly of small to medium-sized components.

1. Casting/Blank Processing
   Cast Iron Model (HT300): Formed via sand casting and subjected to two rounds of artificial aging (high-temperature stress relief) to thoroughly eliminate internal casting stresses. This critical step prevents table warping or deformation during long-term use, ensuring sustained precision. The blank undergoes sand removal and flaw detection to ensure the absence of defects such as air pockets, sand inclusions, or cracks.
   
   Steel Structure Model (Q355): Cut from a solid steel plate with a dense grid of reinforcing ribs welded to the underside. The entire structure undergoes post-weld annealing for stress relief to prevent surface misalignment caused by welding stresses.
2. Machining Processes
   Five-Sided Milling: The top surface and all four sides are milled flat in a unified process, ensuring the fundamental flatness and perpendicularity of all faces of the 3D welding table.
   
   Precision Grid Hole Boring: A specialized CNC boring machine is used to machine all Φ16 reference holes in a single operation. This guarantees a uniform 50mm grid spacing and consistent tolerances and coaxiality across all holes.
   
   Edge Chamfering: All edges and corners are chamfered with an R2-R3 radius to prevent injury to personnel or damage to workpieces, while also avoiding edge chipping caused by stress concentrations.
   
   Reference Surface Precision Grinding: The working surface undergoes secondary finishing on a high-precision grinder to further minimize flatness errors.

• Small-batch production, prototyping, and repair workshops
  Opt for small-format (1000×1000 mm or 1500×1000 mm) 3D welding tables equipped with mobile casters. Use basic angle brackets and standard quick-action clamps; this setup offers high cost-effectiveness and flexible mobility.
• Batch production of precision sheet metal, chassis, and cabinets
  Use medium-to-large cast-iron tables with an integral nitrided finish. Equip them with adjustable supports and angle blocks to ensure workpiece consistency through high precision.
• Pipe and tube welding
  Standardize with V-blocks, rotary supports, and angled support blocks; utilize the 3D hole matrix system to achieve multi-angle positioning for pipe welding.
• Automotive parts and small construction machinery components
  Select tables with high-rigidity steel structures and reinforced legs. Use heavy-duty clamps to withstand moderate loads and continuous operation.
• Cleanrooms / High-cleanliness workshops
  Choose models with chrome-plated surfaces; these are rust-resistant, dust-proof, easy to clean, and do not shed oxidized debris.

• Standard System: The D16 (System 16) 3D welding table adheres to common European standards; its accessories are globally interchangeable, eliminating compatibility concerns, and it is a mainstream choice in European, American, and Southeast Asian markets.
• Essential Documentation: The unit comes with CE machinery safety certification, material inspection reports, and a factory accuracy inspection certificate, facilitating customs clearance and customer factory audits.
• Language Support: English installation manuals, maintenance manuals, and parts lists are provided as standard to meet the needs of overseas customers.
• Voltage / Accessories: For models equipped with an electric lifting base, the motor voltage can be customized to match the requirements of the customer's country.
