D16 3D modular welding table with strong hold clamping system

The D16 3D modular welding table with a strong hold clamping system is a three-dimensional flexible fixturing platform developed based on the D16 standard hole pattern (16mm hole diameter, 50mm grid spacing). Through precision grid holes on the table surface and all four sides, combined with modular clamps, it enables rapid positioning and strong clamping of workpieces in the X/Y/Z axes and at multiple angles. It replaces traditional dedicated welding jigs, adapting to the three-dimensional fixturing needs of complex workpieces, and supports multi-table splicing and automation expansion, aligning with the trend of flexible industrial production.

• Hole Diameter Specification: Ø16H7 grade (φ16.065-φ16.149mm)
• Grid Spacing: Metric 50mm×50mm / Imperial 2"×2"
• Tabletop Dimensions: 800×1200mm, 1000×500mm, 1500×1000mm, 2000×1000mm, etc.
• Flatness / Perpendicularity: ≤0.02mm/m (flatness), ≤0.02mm (perpendicularity)
• Material: S355 steel

Material and Metallurgy: The core work surface is made of X8.7 tool steel / S355J2+N structural steel, with sulfur and phosphorus content ≤0.035%, using hot rolling + cold rolling composite rolling. The metallographic structure is uniform, preventing high-temperature cracking during welding.

Heat Treatment Process: Overall quenching + low-temperature tempering + plasma nitriding. The nitriding layer depth is 0.15-0.3mm, improving surface hardness and resistance to thermal deformation. No warping occurs under localized high temperatures (≤800℃) during welding.

Precision Machining: Five-sided CNC gantry milling in a single clamping operation. Flatness/perpendicularity tolerance ≤0.02mm/m. Full-size inspection using a coordinate measuring machine. Grid hole position tolerance ≤±0.01mm.

Anti-stick and Anti-corrosion Coating: After nitriding, a BAR anti-stick coating is applied, with a thickness of 0.01mm, preventing welding slag adhesion and providing corrosion resistance, protecting the workpiece and the work surface accuracy.

Core Certifications: CE certification (EU Machinery Directive), ISO 9001, DIN standards, RoHS environmental certification. Test reports are available for export.

Market Adaptability:
Size System: Metric/Imperial dual versions, suitable for global markets.
Voltage Adaptability: Matching fixtures available in 110V/220V/380V multi-voltage versions.
Packaging and Transportation: Solid wood fumigated pallets + thickened protective packaging, with IPPC marking, suitable for sea and air freight.

We provide a complete set of export customs clearance documents: commercial invoice, packing list, certificate of origin, copies of CE/DIN/ISO certification certificates, and material test reports;

Both the product and packaging are marked with the HS code (8462910000), complying with the customs classification standards of major markets such as the EU, the United States, Southeast Asia, and South America;

We can arrange door-to-door sea/air freight according to customer requirements, working with experienced freight forwarders covering major ports/airports worldwide.
